NTT DoCoMo to show off 4G handset 

Japanese carrier NTT DoCoMo is set to demonstrate a prototype handset based on high-speed wireless data technology LTE later this month, according to its handset partner, NEC.

NEC said on Monday that NTT will demonstrate the handset receiving streaming high-resolution video across an LTE network at Mobile World Congress, which kicks off February 15 in Barcelona. According to NEC, the handset uses an LTE chipset that was developed by Fujitsu, NEC, NTT DoCoMo, and Panasonic, and first sampled in October.

LTE, the "long-term evolution" of 3G, is the successor to HSDPA and is roughly 10 times faster, providing theoretical downlink speeds of at least 100Mbps and a theoretical uplink of at least 50Mbps.
