** 4G is now spreading, and Sprint/Clearwire have both announced new ** ** WiMAX ** ** coverage in Central Pennsylvania. The extended network – which promises data speeds of 3-6mbps – now covers Harrisburg, Reading, Lancaster and York, and ** ** service ** ** will be available both from Sprint and Clearwire. That’s good news if you live there and have been eyeing the upcoming SprintHTC EVO 4G, the WiMAX-toting Android smartphone due later this year. ** ** Meanwhile next in line for 4G roll-out are New York, Los Angeles, Boston, Washington, D.C., San Francisco, Miami, Denver, Minneapolis, Cincinnati, Cleveland, Salt Lake City, St. Louis, Pittsburg and Kansas City, though while the carriers say they’ll be seeing WiMAX in 2010, there’s no public roadmap. WiMAX service starts at around $30 per month (fixed), though Clearwire are running a discount promotion at the moment; more details in the press release below **

Comparison to 3G


 * ** The speed - The 3G network has a minimum data rate of 2 Megabits per second, whereas the 4G has peak downlink speeds of 40 to 50 megabits per second (Mbps) and peak uplink speeds of 20 to 25 Mbps. **


 * ** The coverage - The new technology will allow Verizon to provide coverage to costumers inside buildings, which couldn't be achieved with the 3G network. **


 * ** Also, the 4G will truly enable video application on the downlink as well as uplink – including but not limited to video-sharing, surveillance, conferencing and streaming in higher definition than is possible with existing 3G technology today **


 * ** The user plane latency achieved in LTE is approximately 1/4th (one-fourth) corresponding latency in existing 3G technologies. **


 * ** It will allow support of multiple users in a time slot; in contrast, existing 3G technology performs one-dimensional scheduling, which limits service to one user for each timeslot. **
