In an October 18 announcement, Sprint, Clearwire, and Time Warner Cable said that they are planning to launch 4G mobile Internet services in New York “later this year.”

While each of the companies will offer their own branded 4G service, the base of these services will be Clearwire’s WiMax technology which rivals the long-term evolution (LTE) technology favored by Verizon Wireless and AT&T. With the New York 4G deployment in place, the number of Clearwire-covered US markets will increase to 57.

The Clearwire brand, Clear, is a dual-mode 3G/4G service, which means that it reverts to the 3G in areas where 4G is still unavailable. The service is presently live in some parts of New York.

The Sprint 4G Service route will give users access to Sprint’s line of 3G/4G handsets which, at present, include the HTC Evo 4G and the Samsung Epic 4G; and USB modems. Sprint has confirmed that its 4G support in New York will go live November 1.

Meanwhile, Time Warner Cable Mobile Internet service, which will include countrywide 3G service and 4G coverage in participating markets, will necessitate a subscription to at least one other Time Warner Cable service.

Generally speaking for all the three companies set to offer their own branded WiMax 4G service in New York, the average 3G network speeds will be 300-1400 K bps for downloads and 350-500 K bps for uploads; while 4G speeds will be up to 6 M bps, with peak downloads up to 10 M bps.
