Wi-Fi HYPEGASM: Huawei demos 10Gbps in lab test
Chinese networks firm says it could see a standard … by 2018
Huawei has planted another flag in 802.11ax standardisation, claiming a demonstration of 10.53 Gbps Wi-Fi throughput in the 5 GHz band.
The lab trial took place on the company's Shenzhen research campus.
The 802.11ax standard is at the very beginning of the long march towards the market. The IEEE board approved the standard effort in March after a year of groundwork.
Huawei says the key technologies that give it a ten-fold speed boost over 802.11ac's current gigabit capability are “MIMO-OFDA, intelligent spectrum allocation, interference coordination, and hybrid access”.
MIMO-OFDA describes a mix of two technologies. MIMO – multiple in, multiple out – uses many antennas at both the transmitting and receiving stations for spatial multiplexing. The same frequencies, by taking different spatial paths, can carry different information.
OFDA – more properly OFDMA, orthogonal frequency division multiple access – takes existing ODFM schemes, and divides sub-carriers to different data streams.
Intelligent spectrum allocation and interference coordination should be pretty self-explanatory, and The Register has no clear idea about what's meant by “hybrid access” in this context.
The Huawei release doesn't mention how many channels were needed to get 10 Gbps throughput, nor how wide the channels were.
The company is chairing the 802.11ax task group, and says it hopes the standard will be ratified in 2018. ®
