I took my time reviewing the Root Metrics report regarding mobile wireless data services in Seattle, WA. because I wanted to understand what the point was they were trying to make. As an aside, I try my best to focus on the key piece(s) of information being presented in the LTE/SON marketplace so that’s why I don’t simply repost hastily… Anyway, Root Metrics has an app/client for iPhone-iOS, Android and Blackberry called CoverageMap that resides in the device/UE and collects service related metrics during operation, much like Carrier IQ except more deliberate (I think) action via the end user, not passive tracking via the carrier… Right now they are advertising this as a crowd sourced informational look at carrier performance, whose results are available at www.rootmetrics.com  Now the surprise, Verizon LTE outperformed HSPA, WiMAX and yes, even HSPA+ in their testing, but note I don’t see Clearwire for WiMAX unfortunately. (Seattle is their backyard after all.) Ok not really a surprise but I surprised you by mentioning it was a surprise.
All in all a pretty interesting use of crowdsourcing, and pretty well laid out findings.

Recently Nokia Siemens Networks and Alcatel-Lucent reminded us that they are helping China Mobile and they are still pushing forward with TD-LTE. I haven’t seen any new information since the original release covered here earlier but I guess the PRs go hot and heavy around CTIA time. OK, large TD-LTE deployment, first of its kind. There will be a ‘commercial’ USB dongle. This is a recording…

Update: We learned that the vendors have so far received 1 market of 200 eNB per market so far. Alcatel Shangai Bell is going to build Shanghai, Huawei is building Shenzen, Nokia Siemens Hangzhou, ZTE gets Guangzhou. TD-LTE could eventually be bigger than the FDD-LTE that is being launched in the US, Europe and other countries.

With the controversy surrounding the GPS interference and LightSquared, it’s easy to forget LightSquared is charging ahead with their plans to launch LTE service. Just this week, LightSquared announced they have signed deals with Cricket (Roaming) and Best Buy (Reseller/Distribution.) What got my attention was PC Mag got some hands on time with the Anydata LTE MODEM. Looks like the LightSquared (recently launched) satellite must be functioning quite well.

I’ve been following this for more than 10 years via Public Wireless. So it’s interesting to me that BelAir is announcing a cable strand mount pico cell, the 100LP, that supports LTE/WiFi. This is an promising area of possible change for the wireless operators and MSOs. More to follow…

Sierra Wireless is launching this groovy mobile connectivity gateway that is LTE enabled (in the future.) I think it’s a good starting point for POS/retail, AVL, telemetry etc applications to kick start the whole LTE M2M enchilada. Attention world: meet The Sierra Wireless AirLink™ GX440.

Tuesday, the Femto Forum, an industry consortium working to promote femtocells, announced the release of their femto applications API. The API is design to enable 3rd party application designers a standard interface to build applications for any femtocell. An example of this would be a security company writing a watchdog to trigger a household alarm etc…when someone attached a home femtocell dials 911 (Emergency # in US.) If the femtocell complies to the API standard then the 3rd party app will interoperate. The goal here is for the femtocell manufacturers to drive more value into the femtocell equation. I think it’s a positive first step. They also enhanced the management standard TR-196 to allow for more interoperability in network management systems, but that’s just housekeeping…

My spin on the proposed US $39B merger of ATT and TMO is that ATT primarily gets to sell iPhones to a 40M customers that didn’t have access to it directly, and can add the TMO PCS 1900MHz and AWS 2100MHz spectrum in ATTs existing portfolio of 700MHz/850MHz/1900MHz/2100MHz. The additional sites are only a minor part of the interest from ATT. The CEO De La Vega mentioned today that the AWS would be used for LTE, thus the current HSPA+ (HSPA Evolution) use of AWS would cease and users would need to ensure their device could be updated to see 3G at 1900MHz, and/or replaced to do that and use LTE at 2100MHz.

Remember, Verizon played the 700MHz spectrum auctions very well and avoided having to deal with the lower 700MHz interference initially, has consistent channels/bands everywhere and gets to start with 10MHz channels at a pretty good price. ATT was not so tuned into this opportunity and has more variable 700MHz spectrum. At the moment they are purchasing Qualcomm’s unpaired upper D/E block chunks but that wont be useful for a while.

 

 

This is also more good for Alcatel-Lucent and Ericsson for upgrades but less good in the long run for Nokia-Siemens.

 

More to come as is revealed…

This is very impressive. University of Illinois at Urbana-Champaign researchers Jennifer Berhnard and Jennifer Lewis have devised a clever method of fabricating an antenna in 3D using silver nanoparticle ink on glass hemispheres. The resulting antenna is a high Q, electrically small (ESA) antenna that outperforms other ESA (monopoles. ) Using these in smart phones could result in dramatically high performance networks. Suddenly 1Gbps that is offered in LTE Release 10 doesn’t seem to hard to imagine. If these are robust, I would expect to see them in special devices like embedded radios, femtocells and so on. This could be big news!

A few months ago, we examined ATT’s purchase of D and E block (lower 700MHz) spectrum from Qualcomm. As of the 11th, there has been some public opposition that has formed around the purchase of this spectrum by ATT. The RCA, Cellular South, Dish and some advocacy groups have filed their thoughts with the FCC. I can see why these guys feel like ATT is a major problem if they can aggregate spectrum in this band. What’s interesting from a technology perspective is that ATT could choose to deploy TD-LTE with this spectrum or work to form/unleash a weird, off balance Release 10 spectrum aggregation scenario on the USA. This would be a unicorn and device support would probably need to be initially unique to ATT. Game on!

VoLTE

VoLTE

Voice over LTE (VoLTE) is the next big thing. In fact, in 24 months, virtually all LTE enabled smart phones will support it. Curious?
Small Cells

Small Cells

Small Cells, previously known as 'femto' or 'pico' cells are possibly a savior to network operators. They offer capacity and coverage to the end user and are inexpensive for the network operator. Why aren't they everywhere?
