LTE Watch: More Verizon Speed Tidbits

AT&T Inc. (NYSE: T) and Verizon Wireless unveiled a few more tidbits about Long Term Evolution (LTE) this week, which kicks off this round-up of news about the mobile broadband technology. (See AT&T, Verizon Undecided on LTE Pricing.)

  • Tom Sawanobori, VP of network strategy at Verizon Wireless, says that even a user on the move should be able to get 5 Mbit/s over its LTE network, which is due to be in 25 or more US cities by the end of 2010.

    The carrier has said it expects users to see 5 to 12 Mbit/s average speeds from the network. "That range includes mobility," Sawanobori said on a GSM Association (GSMA) call Thursday.

    Neither AT&T nor Verizon is expecting to switch on voice-over-IMS VoIP systems for LTE as soon as the networks go live, it also emerged. Verizon says it's planning to do that in 2011 or 2012, while AT&T is looking at 2012.

    Similarly, neither carrier will stop investing in its 3G footprint after LTE is commercially available. Sawanobori says that he expects investment in voice and 3G CDMA networks until the end of the decade.

    In other news:

  • Fujitsu Ltd. (Tokyo: 6702; London: FUJ; OTC: FJTSY) says it has started shipping so-called "Super 3G" LTE base stations to NTT DoCoMo Inc. (NYSE: DCM). The Japanese mobile pioneer is supposed to get its first LTE network up and running before the end of the year.

  • The Dutch LTE auction is said to be attracting nine separate bidders.

  • Canadian CDMA startup, Public Mobile, says it is ready to upgrade to LTE when needed.

    re: LTE Watch: More Verizon Speed Tidbits

    Is an average download of 5 Mbps better than Clear WiMAX?  If inter-working with legacy 3G isn't there day one I don't see the technical advantages of LTE over WiMAX.  Are there capacity, latency or other performance benefits I am not seeing?  I understand long term the LTE ecosystem should offer better devices due to vendor adoption but that is 2-3 years away.  It would be interesting to see the cost of Verizon rollout compared to Clearwire rollout for a similar capacity and network footprint.

    From what I read, Clear only has access to 2.5GHz spectrum. The propagation features is a lot better for area-coverage in the lower parts, e.g. 700-1000 MHz. When it comes to capacity considerations, the highers frequencies would be preferable. I have not seen any wimax profile for the lower bands, and thats quite a sharp contrast to LTE. Clear really has a lot of spectrum, the question is more if the exclusive wimax-deployment is the best use.


    There are modems available which supports LTE to 3G-UMTS fallback, so this would be a temporary issue at worst.


    When it comes to speed, the live LTE networks, and test networks, report peek speeds around 80-85Mbps on 20MHz, and 40-45 Mbps on 10MHz (download). I do think the low average speeds suggested by US carriers is towards not promising more than you can deliver initially. Compared to 3G/HSPA, it is always the peak speed which is promoted. A lot more interesting is the LTE cell-edge/cut off speed, which is reported to be around 1Mbit/s. Thats important
