AT&T Mobility’s recently launched LTE network posted robust throughput speeds during drive tests over the past weekend, according to a report from Signals Research Group L.L.C. (Obviously, the speed tests were conducted on a extremely uncluttered network as the carrier has just begun offering the service commercially.)
The firm noted that testing in the Houston area using a Sierra Wireless Inc. wireless modem showed average download speeds of 23.6 megabits per second, with peak download speed of 61.1 Mbps. The testing also showed that speeds exceeded 40 Mbps 8.6% of the time, 21 Mbps 38.2% of the time and was greater than 5 Mbps 95% of the time.
Uplink speed tests showed an average throughput of 15.2 Mbps with a peak speed of 23.6 Mbps. The testing showed that uplink speeds exceeded 15 Mbps 60% of the time and exceeded 5 Mbps 98.2% of the time.
Network latency tests provided an average speed of 49 milliseconds, which Signals Research said was slower than expected following similar testing on European-based LTE networks, but on part with what other LTE networks in North America have shown.
The network testing also showed that handoffs between the LTE network and AT&T Mobility’s legacy HSPA+ network completed in 2.4 seconds. This portion is somewhat important to AT&T Mobility as the carrier has claimed its ability to fall back to HSPA+ speeds when not in a LTE market is an advantage compared with the CDMA2000 1x EV-DO Revision A network Verizon Wireless’ LTE network must fall back to when outside of LTE coverage. However, Verizon Wireless can then tout that its LTE network currently covers 143 markets compared with AT&T Mobility’s five markets.
AT&T Mobility has said it plans to cover up to 70 million potential customers with LTE service by the end of the year, compared with 180 million pops expected to be covered by Verizon Wireless.
