DoCoMo's LTE Warm-Up
The Japanese operator revealed recently its intention to be among the world's first operators to launch LTE, rather than the first as it was with its 3G network back in 2001. And with a December launch planned, that would put the operator near the front of the pack with Telia Company and Verizon Wireless . (See TeliaSonera on LTE: Just Do It! and TeliaSonera First to Go Live With LTE.)
DoCoMo says it is testing the LTE network for speed, latency, and inter-cell handover stability. The operator wants to confirm data rates of 37.5 Mbit/s on the downlink and 12.5 Mbit/s on the uplink on 5MHz frequency channels, and later maximum data rates of 75 Mbit/s on the downlink and 25 Mbit/s on the uplink in 10-MHz channels.
The operator has been installing LTE base station components on existing WCDMA base station sites. And the devices used in this pre-launch operation are compatible with GSM, WCDMA, and LTE.
