Chinese networking goliath Huawei claimed yesterday that it has broken wireless internet speed records, paving the way for the next generation of commercially available Wi-Fi.
The firm, which has come under scrutiny from western governments over security, said it achieved a record transmission data rate of 10.53Gbps on 5GHz frequency bands at its research campus in Shenzhen, China.
Huawei first began looking into next generation Wi-Fi in 2010 and today it said the new speeds could be commercially available by 2018.
Through its research, Huawei aims to increase data transfer rates that are currently limited by what it describes as "a logjam of classical Wi-Fi wideband radio and baseband processing."
The key technologies that enabled Huawei to gain a ten-fold speed boost over its current gigabit capacity are “MIMO-OFDA, intelligent spectrum allocation, interference coordination, and hybrid access”.
MIMO-OFDA is a combination of two technologies.
MIMO – multiple in, multiple out – involves using several antennae at both the transmitting and receiving stations to improve communication performance.
OFDA – more commonly referred to as OFDMA (orthogonal frequency division multiple access) – takes existing ODFM schemes, and divides sub-carriers to different data streams.
"As the demand for ultra-fast connectivity for smartphone applications continues to drive the need for higher data transmission rates, the next generation of Wi-Fi access will need to deliver a better user experience, especially in densely populated environments requiring high density deployment such as enterprise offices, airports, stadiums, shopping malls and coffee shops," Huawei said.
