NTT DoCoMo details its 150Mbps LTE rollout, plans to double base stations

To this day, relatively few wireless carriers offer LTE at its loftiest 150Mbps speeds. We'll soon get to count NTT DoCoMo among those ranks, however. Alongside the launch of its summer phone lineup, the Japanese network has firmed up some details of its Xi speed-up plans. The initial rollout will focus on the major centers of Nagoya, Osaka and Tokyo, all of which should have 150Mbps access by the end of the year. While NTT DoCoMo hasn't settled on the frequencies it will use, Impress Watch understands that this could involve reusing 1,700MHz FOMA 3G bands to get around local spectrum limits. Regardless of the speeds, there should be a tangible improvement in coverage -- the provider hopes to more than double its Xi base stations from 24,400 in March to 50,000 by the end of 2013. Most of us won't reap the rewards of the upgrade, but it's good to know that Japan's biggest carrier will soon be a first-class 4G citizen.

NTT DoCoMo readies first dual-mode HSDPA, LTE femtocell for December

NTT DoCoMo readies first dualmode 3G and LTE femtocell for December

LTE's frequent gotcha has been indoor coverage: as it often relies on high frequency ranges outside of the US, the signal can drop off quickly at home or in the mall. There have been LTE femtocells before to fill in the gaps, but NTT DoCoMo claims to have the first mini cell site that would cover our needs much more thoroughly. The Japanese carrier's new base station run simultaneous 112.Mbps LTE and 14.4Mbps HSDPA (sorry, no HSUPA upload speeds) on the 2GHz band to keep 3G data and voice working side-by-side with 4G, piping both through a wired broadband connection; there's no need to sacrifice the basics or legacy support just for a better LTE signal. NTT DoCoMo plans to sell the dual-mode femtocell to local homeowners, offices and stores in December. Sadly, there's no immediate word of plans for femtocells that support networks abroad, although the technology's existence gives us hope that we'll see it spread to other providers -- and that black holes in cellular coverage will be distant memories.
