The South African Long Term Evolution (LTE) chipmaker Sequans Communications has released favourable results of a technical trial administered by the Japanese mobile operator Softbank.
“The Sequans AIR receiver demonstrated a clear gain over the default receiver across a wide range of interference levels,” the report stated.
The test was aimed at the value determination of Sequans’ advanced interference technology (AIR) regarding the optimisation of LTE networks.
The experiment was conducted in a laboratory with commercial eNodeBs (base stations) as is used by Softbank’s network operations. A Sequans AIR receiver was contested against a default receiver on the grounds of high and low mobility, in other words vehicular and pedestrian modes.
The Sequans AIR receiver achieved better results than the default receiver in all instances with results of 7dB and 9dB in the low and high mobility case respectively.
Compared to the default receiver, Sequans’ AIR proved to be five (vehicular) and eight (pedestrian) times more capable of handling interference. Measured in speed, this comes down to 10Mbps higher in low mobility and 14Mbps in high mobility.
Georges Karam, Chief Executive at Sequans, said: “In very high interference areas, such as might be encountered near cell edges, users can expect to get three times better throughput – this can mean users staying connected in conditions where other devices would be dropped from the network.
“These gains are meaningful to operators and their end users.”
Sequans Communications is a global leader on the grounds of LTE chip design and the rollout of LTE in the mass market. Chip and equipment plans produced to original design manufacturers also empowers WiMAX networks.
