|1.||ITU Buckled to ‘Big Telecoms’, backtracked and now consider WiMAX/LTE R9/LTHSDPA as 4G||It was cool when we were just calling it 4G, but something seems downright wrong with the UN doing it. I like the controversy!
|2.||IMS has a raison d’etre!
|Finally, I guess we can deploy these much maligned, yet overly complicated disaggregated switches. Seriously, I desperately want change but it’s going to take time to fully comprehend the advantages of the S-CSCF, I-CSCF, P-CSCP over just a SIP interface box for my existing network ala Mavinir.|

ATT announced today that they have acquired Qualcomm’s 700MHz spectrum for US1.92B. This is good for all lower 700MHz spectrum owners as Qualcomm’s Media FLO (FLO TV) was an interferer in the band to the lower C UE uplink and the eNB downlink for A. Also in this transaction, ATT adds 3 missing licenses in the B band. The only wildcard to this is that the D and E block are unpaired spectrum, giving them the flexibility to deploy a TDD type of technology like TDD-LTE to truly take advantage of these unpaired (no separated uplink and downlink) blocks NOW. It would really be more compelling to deploy TDD-LTE over all their 700MHz spectrum to maximize scales of economy etc… this would be an advantage as the TDD-LTE is more efficient capacity wise than FDD-LTE under light-medium loading.
Back to reality, from the text that follows, you can see it looks like they are content to wait for Release 10 (LTE Advanced) in 2013 to allow them carrier/spectrum aggregations providing them additional throughput down to the UE.

Saw this announcement by Nokia Siemens and T-Mobile USA and, well, muhahahahahaha…Seriously, I don’t really understand what the thinking is. It looks like we can safely eliminate T-Mobile from the ‘going to carry the iPhone’ rumors. Isn’t it strange that NSN is building LightSquared (satellite LTE service) and they seem to work hard to isolate T-Mobile from using that until Release 11 of the standards (like 2013) ? On the other hand NSN can probably reuse their Flexi Basestation’s LTE MODEM, create a custom package, and then create a special 32 Power Amp (8 carriers X 4 TX paths) card per sector for T-Mobile USA. Also, it looks like T-Mobile is in the market to acquire the additional 20-30MHz in each market to make this happen too.I struggle to imagine the 3x632Mbps=2.016Gbps per site of backhaul to get ready for too, although that’s a common issue with all data deployments. Christmas is *just* around the corner in Espoo, Finland!!! More details after the break…

The internet is buzzing with reports of 2 minute delays when transitioning from the EVDO or LTE to the other. (Both ways.)
This handover is very complicated. There are PCRF interactions, AAA etc…They can patch it quickly, but may spend a lot of man years optimizing this.

One of the aspects of SON/LTE networking that keeps me excited, is that I keep coming across technologies and/or innovation. I’ve put together a small list of the 9 most interesting things (to me) that are uniquely LTE related. I didn’t ask these guys for permission to talk about their coolness, so I advise you to NDA up and contact them on your own if you are interested. Most of them have pretty good web based information….And now the list… Read Full Article →
Looks like the US Government is asking Santa for some femtos and WiFI in the Capitol buildings. Since femtos are really the first SON (Self Organizing Network) devices on the market, I had to point out this proposed legislation. Notice they’re not asking for repeaters or DAS. Femtos/wifi makes a lot of sense from a utility perspective yet I just can’t help smirking about the fact that they’re finally fed up with poor inbuilding capacity … and how quickly they break out the pens and checkbooks to fix it.
Senators Snowe, Warner Introduce Legislation to Increase Wireless Coverage
Bill would require federal buildings to install small wireless base stations to free up commercial network capacity
WASHINGTON D.C. – U.S. Senators Olympia J. Snowe (R-Maine) and Mark R. Warner (D-VA) introduced legislation requiring the installation of small wireless base stations in all publicly accessible federal buildings in order to increase wireless coverage and free up essential commercial network capacity.

Sprint announces 3 vendors for the new multimode basestation plan. (Mission: combine all spectrum into a single box, likely different radio technologies.) They say iDEN is going away (the 800MHz technology) and they don’t say a peep about LTE nor really WiMAX. There’s so much hype around LTE, that caught my attention. What does it all mean?
VZW launches their LTE service with their 700MHz spectrum. There are 2 USB dongles to choose from, an LG and Pantech for $99/ea. The service cost is $50/mo for 5GB. That’s not a lot of headroom, but it may be the ticket if you need REALLY FAST access at the airport.
BTW, while there are seemingly daily LTE announcements of trials and/or launches, I felt this one is significant because it’s really the first in the US and is being heavily marketed at a level to catch the average consumer’s attention.
