“2011 Analyst Outlook for Wireless” – Notes from Wireless Technology Forum, Atlanta

(from our Atlanta desk)

I attended the Wireless Technology Forum, Atlanta meeting on 18 Nov. The topic was “2011 Analyst Outlook” – an excellent one as we all are very curious to know what comes in 2011 in Wireless. Here are the notes from the meeting :

Speakers :-

There was an excellent lineup of speakers –

Keynote : “Prospects for LTE in 2011″ by Steven Leonard, Regional Director, Data Sales, Verizon Wireless

Panelists :

- Phil Hendrix, Principal Analyst, Institute for Mobile Markets Research (or IMMR)
– Jorge Fuenzalida,
Vice President, Strategy and Technology Group, inCode Telecom Group (now part of Ericsson)
- Jeremy Schneider,
Principal, Telecommunications, McKinsey & Company, Inc.
- Robert Prudhomme, Vice President, Client Services, Telecom Practice, The Nielsen Company

Moderator : Gerry Purdy, Principal Analyst, MobileTrax

Steven Leonard (Verizon Wireless) on LTE in 2011 :-

LTE offers 10 times faster speed compared to 3G networks. Verizon will have LTE in 38 markets by 2011. Verizon has the valuable 700 MHz spectrum which allows high speed and data accuracy in network transmission. LTE utilizes the MIMO technology. MIMO (Multiple Input, Multiple Output) is a technology that  increases in data throughput and link range without additional bandwidth or transmit power.

Another key aspect of 2011 is the growth of Tablets and accompanying data demands. 181% growth expected in Tablet usage in 2011 over this year. Verizon is the only carrier with contiguous 4G spectrum in USA (AT&T may disagree : )

Lte is 3.5 times faster than CDMA in how far signal will travel without diluting. It offers Latency near 30 ms where earlier it was 150 ms.

Verizon 4G leadership (per Steven) :-

    – Joint innovation lab
    – Open devl
    – Verizon developer community
    – LTE innovation center
    – M2M management center in partnership with Qualcomm

Note : M2M or Machine-to-Machine is the new wireless industry developing around putting wireless chips in home appliances, hospital equipment and other such non telecom functions).

Verizon Launch mkt this year – Athens and Atlanta are included

Wireless broadband features in LTE include :-

    1 Advanced applications :- like Entertainment and Music

    2 Innovative devices

    3 Location agnostic : Whereever you are availability

As per Steven, Verizon 4g network rollout will be completed in 2013 in the USA.

Phil Hendrix (IMMR) :-

Phil gave a presentation on Mobile Commerce, an area which is rapidly evolving. The most happening event in USA on Mobile Commerce has to do with NFC phone proliferation expected in 2011 with Google Nexus S and Apple iPhone – both NFC enabled phones coming out potentially as per reports.

As per Phil, Mobile Commerce has three perspectives :-
    – Consumers : mobile shopping
    – Brands : mobile advertising
    – Retailers : m-commerce

8 dimensions which together constitute mobile commerce:-
    – Mobile Shopping
    – Mobile Funds Transfer
    – Mobile Advertising
    – Mobile Rewards
    – Mobile Coupons
    – Mobile Booking
    – Mobile Offers
    – Mobile Payments

Today we are only in the initial stages of Mobile Commerce.

Certain trends are accelerating Mobile Commerce. These Accelerators include :-

    – Location-Based
    – Hyper Local sensitivity – what is around us
    – Social Media
    – Yield Management
    – Supply Chain integration
    – Big Data

Jorge Fuenzalida (inCode) :-

inCode Telecom Group, the telecom strategy consulting firm, has been acquired by Ericsson recently. inCode is famous for its “top 10 predictions” in wireless every year. Jorge said that these are not finalized for 2011 but offered a Sneak preview of the top 10 :-

Predictions :-
    1) Over the Top goes over the top (in other words, over the top video/OTT or IPTV accelerates and everything in video goes online)
             2009-Netflix becoming very popular – CPE based OTT
             2011-all content goes online eg Google TV or other such offerings
    2) Tablet rush – in 2011 it will overtake netbooks
    3) The new Gold Rush in 2011- wireless rural broadband – due to government stimulus

Well said, Jorge.

Jeremy Schneider (McKinsey) :-

Core wireless has matured. Revenue growth has slowed in voice and messaging

What is next then? Three predictions (since it is the day of 3 predictions from all analysts : ) :-

1) Data will grow much more than what most analysts are calling for. McKinsey thinks 17 times growth from 2009 to 2012 in mobile data
     McKinsey thinks that even this number is relatively conservative. They think it could be 25 times growth by 2012.
     Tablets, mobile video and broader consumer adoption of mobile browsing will drive mobile data growth.
2) Enterprise will outstrip Consumer in wireless (this is surprising as per me as consumer has been the bigger driver of smartphone data via apps so far)
     Enterprise mobility will enable employee mobility etc
     – 6 times higher willingness to pay in enterprise consider to consumer
     – big market. M2M sensors estimates keep rising on a daily basis
     – many verticals are ripe for innovation

     Healthcare is particularly exciting in the M2M arena.
     Healthcare will expand in 5 trillion dollars overall in 5 yrs. At current rates healthcare will be 30% of us GDP
           * Remote Monitoring
           * Remote Consultation
           * Medication Management
           * Health and Wellness

3) New directions in Application Architecture
     – Data growth needs efficient network
            * 30% time waiting on mobile browsing
     – Platform independent tech like HTML5, JIL (Java Intermediate Language), WAC (Wholesale Application Community – the operator consortium), SNs (?)
     – Delivered in the cloud (aha – Cloud Computing – we know it)
          * Consumer – Large portions of iPhone apps already on the Amazon Cloud or EC2
          * Enterprise – 40% savings by moving to cloud

Robert Prudhomme (Nielsen) :-

Growth has slowed in postpaid the USA. Prepaid is going well.

Only verizon and AT&T were able to get net adds in Pospaid this year. However, all of these came at the expense of T-Mobile or Sprint (no wonder, with 80%+ market penetration for wireless in USA, you can only get new customers by poaching from your competitors)

AT&T is doing well with its Connected Devices business, however a concern is that Standards and Business models around these new devices are not clear and their financial worth is not known.

The erstwhile prepaid kings, the carriers Cricket and Metro are suffering as the Big-4 wireless operators are getting most of the prepaid now.

Sprint is competing on pricing while it tries to retain its customers who are churning fast. The No 1 reason to win a customer now is promotion and pricing. This means price wars as are seen in $50 all you can eat plans from some carriers. Now, Sprint is even undercutting T-Mobile in pricing. (my conjecture is that the profit margin in $50 all you can eat plan is really next to nothing).

Of course wireless has lot of bright areas too on the premium side – mainly Record smartphone sales. On premium side, smartphone (driven by top smartphones like iPhone and Android phone) sales are driving fast growth.

Wireless Tablets remains an unpredictable play for the operators. This is depicted by the fact that only 1/10th of iPad tablets sold are activated on the AT&T network. Rest are using WiFi or exported out of the country. (But AT&T still scores as it has a respectable nationwide WiFi network – of course free public WiFi for broadband customers is a customer retention strategy by carriers like AT&T and not really a revenue generator).

Smartphones are driving increases in App adoption (finally a direct reference to Apps)
    – 59% smartphone owners download apps
    – 9% feature phone owners download apps

AT&T – 74% postpaid net adds in last quarter are iPhone customers (did I get it right – 74% ?).

Interesting stat from Nielsen : -950,000 netadds lost from AT&T if they lost iPhone exclusivity per Nielsen estimates. In other words, with the impending Verizon iPhone and potentially on other carriers too, AT&T might loose almost 1 million net adds per quarter. A significant number but one AT&T is already planning for most likely.

In France and other European countries, when iPhone exclusivity ended with one carrier, Apple doubled their share or more in some cases. So one can conclude that the Apple stock price may be trading at a discount if its market share is about to rise (now let me run and buy some Apple stock.. : )

Overall an excellent discussion on the 2011 Outlook for US wireless by some Industry heavyweights in the Analyst world. Congratulations to the team at Wireless Technology Forum (Atlanta) and especially to Gerry Purdy of MobileTrax for putting together this awesome event.

Notes from Wireless Technology Forum SIG on Mobile Video, Feb 11 2010

(from our Atlanta desk)

I attended the Wireless Video SIG organized by Wireless Technology Forum, Atlanta on Feb 11, 2010 at Goizueta Business School, Emory University. The title was :

“Mobile Video : New Horizons, New Possibilities”

Here are the notes from the SIG :

Panelists :

David Barnette, Regional Vice President, Clearwire

Craig Kirkland, CNN Mobile

Dr. Nikhil Jayant, Executive Director, GCATT

Mark Nagel, Mobility Video Services, AT&T Mobility

Susan Schedel, Director, Business Development, FLO TV (Qualcomm)

Clay Garrett, Director of Visual Design, N4D

Moderated By : Dr Benn Konsynski, George S. Kraft of Business Administration, Goizueta Business School, Emory University

Overall – an excellent session on Mobile Video arranged by Mobile Video SIG Chair Caroline Dunn and Ashok Kumar.

Dr Konsynski started off with saying that there is a tidal wave of mobility and also of video. There exists a confluence of each. Moreoever, UGC (user-generated content) and other actors are confounding these influences. There is also a strong pursuit of standardization in this space.

David Barnette – Clearwire :
Clearwire leading 4G space in United States. Clear (Clearwire markets its 4G wireless service under the brand name “Clear”) is present in 27 cities covering 30 million people. Clear finds that usage for its service is increasing rapidly. Users are moving double the bandwidth compared to first generation network that they had. As they say : “If you build it, they will come”.  David says that Mobile experience with Clearwire is not about dropped calls (dig at traditional wireless operators :) but rather can you take a video while driving and not dropping the signal. Clear is judged by video apps and not really voice. “does it pass the hulu test?”.

Davind mentioned that typical phone customers are on 3G but have no expectation for video for 3G. This is not the case when these consumers adopt 4G and WiMAX. Clear thinks that video will become standard expectation with consumers in due course and then the 3G networks just won’t suffice. Price structure is crucial for marketing mobile video. In future you buy bandwidth on Wireless and voice is just one of the many apps offered on the wireless channel.

Consumers – most devices and networks are designed for 3G svcs. But Clear is evangelizing with consumers and manufacturers that new age services and products need to be designed for 4G.

iPhone has opened lot of eyes. Clear is excited about the potential of Mobile web. Clear considers itself as an ISP and not as a wireless carrier (interesting !).

Dr Konsynski asked Clearwire about extraordinary innovations once the WiMAX network is in place. Clear executive said that it is normal everyday things which will have better capacity and pricing on 4G network. On business side, Clear gets requests (from enterprise customers) for high speed business apps in places where it is normally difficult to reach using the older networks.

Craig Kirkland – CNN Mobile :

Craig said that CNN (United States’ leading news network and TV channel) is bullish on mobile and in fact quite excited about it. Short and longer videos both will succeed, eventually, CNN feels. They say mobile video is in experiment stage right now. Their iPhone app is the most successful so far. It has video clips and streaming videos of major events (eg Haiti disaster reporting). CNN sees lot of challenges as well. Craig used to work at Alltel before (and so has a carrier perspective as well). CNN Mobile is  excited about the device evolution. But CNN is concerned about mobile network quality. They are hoping the WiMAX LTE solves the network issue (indeed- a customer does not care whether it is LTE or WiMAX, Customer only cares about what experience they get). CNN Mobile also worries about discoverability challenge on app stores. CNN Mobile team focuses on discoverability a lot.
Craig said that CNN Mobile believes in net neutrality, even though a small set of users hog a a majority of the bandwidth.

Dr Konsynski says that Prodigy example (remember that now defunct high-flying ISP of the 90s) shows that if you throttle network for a small set of users, you can damage experience of your larger user base. So have to tread carefully in network throttling practices when managing high volume data users.

CNN has lot of internal resources dedicated to Mobile effort.

Dr Nikhil Jayant – GCATT :

Dr Jayant has an extraordinary background in academia and corporate. He said that he wanted to recognize the underlying core technology of Signal Compression. He said that signal compression was a great enabler to transfer CD-quality music and other things. Video is even more compressed signal. Video signals are compressed today by factor of 100 to 1.

Mobile TV factor compression today is sometimes 200 to 1 and 300 to 1. Dr Jayant expects 1000 to 1 video compression in his lifetime. He says network is fine but services on that is key. Video has the potential to become even more exciting in the next 5 to 10 years.

Mark Nagel – Mobility Video Services, AT&T Mobility :
Mark said that AT&T is focused on consumer and consumer experience. First mobile video app from AT&T stable was MobiTV in 2006. 3-4 frames per secs. You had to buy a $20 Data plan to get MobiTV. MobiTV was popular. Now they have a more advanced product from Qualcomm (called FLO TV) and it costs 9.99 per month. Nickelodeon is their most popular show on the mobile TV channel. He said that consumers still need to find the right app – consumer awareness about Mobile TV is the biggest issue right now.

Susan Schedel, FLO TV, Qualcomm :

The carrier partnership is most crucial for Qualcomm to popularize its innovative FLO TV service. They are trying to understand TV on the Go. MediaFLO (the network operated by Qualcomm for its FLO TV network) has high usage per day per user. FLO TV was started 5 yrs ago. They started with carrier partners like AT&T and Verizon. They have wholesale relationship with the consumer so far. Now, Qualcomm is also introducing direct-to-consumer channel called “Personal TV” sold via Best Buy or Amazon (in my personal opinion, they face stiff competition from Apple iPad TV channels in near future). They have a dedicated device for Personal TV.  Eg parent does not want to provide a phone to a kid but can give a Personal TV device. They are also working on backseat vehicle TV (personally, I think Qualcomm and Apple are on a competing path in 5 years – probably the reason why Apple did not choose SnapDragon processor from Qualcomm for their iPad device). They are also developing TV for the Android platform also.

FLO TV has DVR type capabilities as well as interactivity on roadmap for a user to stop, record and do catch up television.

Clay Garrett, N4D :

N4D is about 3D imaging. Focused on content. Volumetric rendering like catscans, weather etc.
Trying to solve headaches in watching 3D etc (think Avatar). As a content firm, they want to know about network viability and compression to allow them to deliver the content to consumers reliably.

Dr Konsynski – stretching the capabilities is important. Clay said that brain and eyes can cause issues eg in the recent blockbuster Avatar, 3D people said that content felt as if coming out of the screen can cause headaches and nausea. So, N4D is working on cutting-edge technology trying to make it easier to consume this 3D content.

CNN – iReport (user submitted video content on CNN) is popular with all audience ages even though CNN originally assumed that only youngsters would be interested.

Clear – Maximum adoption for Clear service in Atlanta area is in the midtown (think young, urban audience in townhouses and condominiums rather than suburban family crowd). It seems that the lifestyle pattern is more important to predict user adoption rather than age profile for such services.

Dr Jayant – Quality of Experience is key as Craig pointed out. eg Healthcare over broadband may be a big factor for success of broadband.

David (Clearwire) said that in few years Internet traffic and video traffic will become one and the same thing.

Audience question – Why will WiMAX succeed (when most major carriers are touting a LTE future) ?

David (Clearwire) – speed to market is important. WiMAX is available today with users. He said that Clearwire is aware of LTE but he says that they have spectrum positions. They say LTE and WiMAX are very close and feel that there may be dual mode devices and networks in the future. Eg combined LTE and WiMAX base stations and devices are alredy being built.

Audience – all said and done, what about mobile battery life?

Mark Nagel – FLO TV is broadcast-only technology and so battery experience is not really that bad.

CNN Mobile – battery issues bother them but the CNN exec agreed that consumers still want cool thin phones, regardless of battery issues.

International issues :-

CNN – have a large International operation. In general, they merged international and domestic products together. There are different subsets for both and there are pros and cons abroad compared to the US environment.

Dr Jayant :-
What consumers expect abroad in different parts of the world could be different from USA. Willingness to pay and Broadband policy may influence growth in other nations. Eg Finland declared recently that broadband is a birthright (::) (wow – won’t fly in the USA).

Mark Nagel (AT&T) – Rich experience in iPhone compared to before. Opening up new models and apps.

Dr Konsynski – why did qualcomm go direct to consumer ?
Mark Nagel (AT&T) downplayed that question. He said that AT&T is not competing with Qualcomm for Mobile TV. Bigger issue is consumer awareness.

Clay (N4D) – 3D has bad rep. But Avatar kind of experience may help popularize it and make it more consumer-friendly. Consumer education about 3D needs to be increased.

Net Neutrality :- (tough one)
Clear – flexibility is key and it is imp that people can push and pull content freely.

Mark Nagel – AT&T is open (ok!). Network is precious and have to manage the network using innovative techniques.

Dr Konsynski provided a killer line : If Content is King, then Context is Emporer.

Dicoverability, search, context :-

CNN – discoverability is about people making aware of their mobile app and moving across CNN properties.

Mark – trialing of apps is useful for discoverability but too many apps make it difficult to innovate in this area. Too many apps is a good problem to have ultimately. Somehow discoverability issues need to be solved via some innovation.

A fabulous panel discussion on Mobile Video set up by Wireless Technology Forum, Atlanta. Thanks to Caroline Dunn and Ashok Kumar of WTF.

A Primer on LTE

LTE or Long Term Evolution is a 4G wireless technology and is considered the next in line in the GSM evolution path after UMTS/HSPDA 3G technologies. LTE is espoused and standardized via the 3GPP or 3rd Generation Partnership Project members. 3GPP is a global telecommunications consortium having members in most GSM dominant countries. 3GPP specifications are based on GSM evolution path of wireless communications. GSM is the most prevalent wireless standard in the world and has maximum number of subscribers globally.

The impact of LTE is so big that even powerful carriers which were on the alternate CDMA path like Verizon Wireless of United States, have decided to go with LTE in their next generation 4G evolution. Firms like Verizon and MetroPCS of USA have all but dumped the CDMA technology path almost dealing a blow to the CDMA owner Qualcomm, although the latter is much more diversified so it is not really short of business models.

LTE vs WiMAX
Whereas WiMAX emerged from the WiFi IP paradigm, LTE is a result of the classic GSM technology path. LTE is behind in the race to 4G with WiMAX getting an early lead with the likes of Sprint ClearWire and several operators in Asia opting to go with WiMAX in the near term. So where WiMAX has a speed to market advantage, LTE has massive adoption and GSM parenthood to back it up.

It is widely believed by market analysts that LTE will win ultimately but WiMAX will find adoption in frontrunner communities and niche business models which tend to take up technology faster. WiMAX vendors will have you believe that speed to market is too important to ignore. History suggests otherwise in case of wireless industry. It is also believed that ultimately, wireless industry will figure out a way to wed the two 4G technologies so the end product in few years might be a nice amalgam.

So ultimately, what standard an operator uses might be a moot point in the long run. The inter-operability would be just too great to get hung up on the wireless standard. The fact that both WiMAX and LTE are all-IP means that a cross-connection will be a piece of cake at some point in future.

In terms of speed, Fixed WiMAX lacks LTE in speed but Mobile WiMAX may catch up with LTE on this front. For an overview on WiMAX, refer to our post “A Primer on WiMAX“.

LTE Technology
LTE builds on 3GPP family which includes GSM, GPRS, EDGE, WCDMA, HSPA (High Speed Packet Access) etc. LTE is an all-IP standard like its peer WiMAX. LTE allows for rich applications and business models which include ultra-high speed voice, video and data. It also enables integration with the classic internet infrastructure which is all-IP based.

HSPA (High Speed Packet Access), the 3G GSM standard popular over near-term, offers uplink speeds of 11.5 MBPS and downlink of 28 MBPS. Whereas LTE offers 75-100 MBPS Uplink speeds and 250-300 MBPS downlink speeds. Compare this with 20 MBPS U-verse speeds of AT&T wired broadband network U-verse and 50 MBPS speeds in Verizon FIOS TV service. In a nutshell, LTE will beat the fastest wired broadband delivery High Def TV today (in USA) by order of 1 to 4 or 1 to 2 depending on which wired broadband we are talking about. That said, many carriers like AT&T believe that HSPA and its faster cousin HSPA+ will compare well with early WiMAX speeds and so there is no rush to LTE yet for these kind of carriers.

Some key characteristics of LTE are described below :

  • Increased Data Rates and High Efficiency : LTE is based on OFDM Radio Access technology and MIMO antenna technology (just like its cousin WiMAX) which offer excellent modulation technique for achieving powerful spectral efficiency.  Think of the OFDM wireless spectrum as a series of very fine and narrow wireless  bands and each band gets allocated to various service providers.  LTE offers higher data transmission rates while utilizing the spectrum more efficiently. This translates to an ability to support many more multitude of subscribers than is possible with pre-4G spectral frequencies. LTE is 2 to 5 times more efficient in spectrum utilization than the most advanced 3G networks.
  • Radio Planning : LTE signal goes far and wide and covers a larger geographic territory. LTE signal is way faster than the existing wireless transmission resulting in higher user response times.
  • IP environment : LTE is all-IP which permits new enhanced applications like real time voice, video, gaming, social networking and location-based services.  The concept of wireless ubiquity comes alive with LTE processor chips in everything from netbooks to mobile phones to consumer devices; all these devices talk to each other seamlessly and effortlessly.
  • Inter-operability : LTE IP network co-operates with circuit-switched legacy networks resulting in a seamless network environment and signals are exchanged between traditional networks, the new 4G network and the IP-based internet seamlessly.

LTE Applications
LTE will enable applications previously unheard of. Wireless ubiquity is a given. All consumer devices. communication and computing resources may be enabled on the wireless network courtesy of chipmakers like Intel who are eagerly building in WiMAX and LTE in future chipsets which will be embedded in all sorts of technology devices that one can imagine.  Social Networking and human-technology interaction (HTI) will take on a new meaning. Human-technology interface and resultant communication could be as seamless and as effortless as the Tom Cruise movie Minority Report makes it out to be (ok we are bragging a bit now).

Web 4.0, if you will, may just comprise the Wireless as an integral element of the hyper-connected world via LTE and WiMAX enablement.  Broadband TV might not need wired cables anymore and new MVNO service providers may emerge who enable wirelessly driven TV and broadband internet. Business users might exchange massive amounts of data while on the go at the flick of a button (or touch). Interacting with your Flickr and Picasas photo streams from mobile devices might be a breeze. Games will cross wired / wireless domains and mobile location will figure in the gaming context naturally. Location-based may take a new meaning with location being the true IP beacon determining the application context in a flash, thereby offering a ultra-personalized mobile experience to the user.

LTE Timeline
Operators are just now fully deploying 3G using WCDMA or UMTS/HSPDA. WiMAX is coming in via ClearWire in USA and several operators like BSNL in India and many others in Middle East and Africa. The first LTE deployment in USA is with relatively tiny MetroPCS which may just beat the big 3 LTE carriers (AT&T, Verizon and T-Mobile) in the race to 4G. Verizon is claiming 2010 LTE deployment and AT&T is taking a more patient approach and states that LTE is in 2011-12 timeframe. China is unique, as usual. They have taken the TD-SCDMA 3G route which is a “unique to China” standard.  Chinese 4G strategy is not clear still. India is more LTE centric like the West with major carriers like Airtel and Vodafone adopting the LTE route. LTE in India is many years away as India’s regulator TRAI has not even awarded the 3G spectrum licenses yet.

Japan, we won’t even go there..

A Primer on WiMAX – see our post referenced on wikipedia

Our article on “A Primer on WiMAX” was liked so much that a link to it was created on wikipedia under Notes and References section of the main WiMAX page :

http://en.wikipedia.org/wiki/WiMAX

Thanks to the team or individual who put our post on wikipedia. So we have decided to create “A Primer on LTE”. LTE is the competing 4G technology and coming a little later than WiMAX. Stay tuned for the LTE primer on this blog.

Notes from Telephony Live 2008, Chicago

Some other interesting discussions at the Telephony Live 2008 which I attended last week :

XO Communications : has a broadband VOIP service platform for corporate clients and uses BroadSoft platform. BroadSoft Platform allows SPs like XO launch service quickly and allow the configuration capabilities needed for an enterprise grade launch. According to XO Director of Product Management Nicola Jackson, feature packaging capability in the BroadSoft software was critical part of the successful launch.

TowerStream CEO Jeff Thompson participated in the panel “Service Provider of Tomorrow” and spoke about their Fixed WIMAX services and how launch of XOHM network by Sprint has validated the business case for WiMAX and has attracted the desired visibility from ecosystem partners to embed WiMAX in more devices and services. Jeff mentioned TowerStream mentioned by maintaining extreme focus on WiMAX services and not getting into VOIP or storage periphery services.

Tellabs was the lead sponsor for Telephony Live 2008 and presented a very interested use case on Latin American IP service provider Diveo. Diveo has launched a full IP MPLS compatible VPN service for business customers in South American nations. Diveo has 1500 customers including the Brazilian energy giant PetroBras and several financial majors in that part of the world. Tellabs exec mentioned that they are letting the core of the network continue to be an ATM/Frame Relay to allow the businesses to leverage existing investments. MPLS and IP functionality is being introduced on the edge to provide QOS and policy management functions.

The founder of NextGen Marketing group illustrated the success of one of their startup clients Sojern, Inc which has created an innovative business model of printing local advertising on internet boarding passes of various airline customers. The local advertising prints ad and event information based on the destination of the customer or flight layovers. NextGen Marketing Group is the “virtual Chief Marketing Office” where they provide strategy and marketing services in an outsourced manner to firms large and small. NextGen customers include Sojern, AirCell and NextGain.

City of Chicago CIO Hardik Bhatt mentioned how the city is tracking the city workers around the city and advising them on energy usage and route optimization. The city has an innovative IT dept and has introduced Mobile Asset Tracking and 311 VAS services. Unfortunately, state the city CIO, broadband is still not universal and 25-50% from low income families have no internet access limiting the scope of internet based services.

Ben Shin, VP Product Management of Sprint’s XOHM business unit mentions that it is not always about technology. Technology must address social needs and social concerns and also make things easy for consumers. XOHM is an all IP service with no service contracts and open ecosystem to encourage developers and partners to develop products and services for this environment. XOHM DayPass cost just $10 and provides all you can eat access for one day.

All participants agreed that future of communication lies in things like content, Location-Based offerings, Mobile Advertising, Mobile Gaming, Business Process Outsourcing etc. There are 250 apps produced for Facebook every day and this shows an open developer friendly internet can attract scores of developers to develop innovative apps. Same environment needs to be encouraged in the mobile space to achieve similar growth patterns. Many participants agreed that devices like iPhone and Android will shift balance of power to content, internet and application firms from the typical service providers.

Mobile Backhaul Network

Attended a webinar today on Mobile backhaul networks conducted by Wireless Week magazine (www.wirelessweek.com). There is plenty of debate on what kind of backhaul works best for emerging 4G wireless techs ie WiMAX or LTE. Folks from Juniper and France Telecom/Orange and some others argue that an IP/MPLS (Multi-protocol Label Switching) backbone is a great solution for a broadband mobile backhaul. Their reasoning :

  • MPLS is good mobile back haul for 2G, 3G,  LTE and WIMAX with both IPv4 and IPv6 traffic
    • Supports flexible connectivity and configuration models
  • MPLS is future proof due to its flexibility
    • Can support whatever 4G networks come up with
  • Mobile backhaul requires flexibility due to other reasons as well
    • Many technologies co-exist
    • Multiple deployment scenarios co-exist

MPLS has delivered in landline networks. It is adaptable and hence a good candidate for mobile backhaul. One does not know how mobile backhaul evolves so it is better to position a flexible tech like MPLS for mobile backhaul to accommodate the various configurations which 4G folks come up with.

Our take – Juniper and similar firms have invested heavily in MPLS equipment, so this standard fits them naturally. If we talked to the WiMAX equipment folks, they would like a wireless WiMAX-based backhaul. Fiber manufacturers would like a predominance of a fiber-based backhaul. Really, all of these are viable backhaul solutions.
