A final set of specifications for Long Term Evolution has been approved by the 3GPP. LTE, which uses OFDM and advanced antenna technologies such as Multiple Input Multiple Output, is the next evolutionary step in the HSPA technology path. LTE will enable downlink peak speeds of 326 Mbps and uplink peak speeds of 86 Mbps, both with 20 MHz of bandwidth. It also reduces latency to a 10-millisecond round trip between handsets and the base station. So far Verizon Wireless is the only U.S. network operator to formally declare LTE as its 4G technology of choice.
