I was looking at the Press Releases from US Cellular regarding their LTE market launches. You can see them here. Anyway the key things to me were, firstly the where….
The November rollout expands the 4G LTE footprint in select cities in Iowa, Wisconsin, North Carolina and Oklahoma, and brings 4G LTE coverage to some of U.S. Cellular’s leading markets in Illinois, Maryland, Missouri, New Hampshire, Vermont, Virginia and West Virginia. The next wave of market launches will follow shortly in Rockford, Ill., Medford, Ore., Yakima, Wash., and Knoxville, Tenn.
And this…the how…
King Street Wireless, L.P. currently holds 700 MHz wireless spectrum in 27 states and is partnering with Chicago-based U.S. Cellular to deliver high-speed 4G LTE service to U.S. Cellular’s customers in several of the carrier’s markets
So I was looking at some of these areas, and yes, there are Channel 51 DTV interferers in some of the same areas.
Random pick, how about West Virginia?
power | 15 kW (kilowatts) (effective radiated power) height above average terrain | 0 feet height above ground level | 187 feet height above mean sea level | 1106 feet directionality | directional
As you will note from the chart, there is a 15KW transmitter at Channel 51, so huge interference with the lower 700MHz UEs… So looking a little closer at the spectrum ownership, they have a B channel/block in that market. So all this wind up to say:
1) Kudos to US Cellular for deploying lower 700MHz LTE
2) Unlike what Qualcomm was trying to convey in their report to the FCC, US Cellular is using the lower 700MHz Channel B without issue, probably some sharp eNB filters are helping out.
It’s time for the rest of the market to jump in and play here. 700MHz LTE is a game changer based on the rich variety of spectrum owners and owing to the physics that the propagation of 700MHz channel is great compared to the typical 1900MHz or 2100MHz channels used for 3G.
Keep up the good work US Cellular.
Oh yeah, they have a cute video too. Check it out.
