Ericsson has demonstrated HSPA (High-Speed Packet Access) with download speeds up to 168Mbit/sec. and 24Mbit/sec. on the uplink, the company said Monday
The demo used a prototype consumer device and commercial network equipment, with SingTel in attendance at Ericsson's invitation.
To reach 168Mbit/sec., Ericsson used a number of radio tricks, including antenna technology MIMO (Multiple-Input Multiple-Output) and sending data over several channels at the same time. MIMO uses multiple antennas in the base station and on the device to increase speeds.
The demo will also be conducted at Mobile World Congress in Barcelona, according to Ericsson.
Besides HSPA at 168Mbit/sec., Ericsson has also demonstrated HSPA with 42Mbit/sec. using a single channel and 84Mbit/sec. using two channels. Operators already offer HSPA at 42Mbit/sec., but they have to use two channels. By only using one channel aided by MIMO, operators can "be much more efficient with their valuable radio spectrum", Ericsson said.
The first commercial network implementations of single-carrier HSPA at 42Mbit/sec. and dual-carrier HSPA at 84Mbit/sec. are expected this year. The company didn't provide details on the arrival for HSPA at 168Mbit/sec.
Today, 79 commercial HSPA networks offer download speeds of 21Mbit/sec. Add to that 13 commercial HSPA networks that can offer up to 42Mbit/sec., and five operators that have committed to HSPA at 84Mbit/sec., according to the latest statistics from the Global mobile Suppliers Association.
Mobile broadband speeds is an inexact science and users should be happy if they get half of the quoted top speeds. Speeds vary owing to congestion, distance from the base station, local conditions, hardware, software and other factors, Ericsson said.
