Check out our HOT AIR INTERFACE for 5G – Huawei

"Please sir, pick my standards sir!" begs Chinese tech giant

Huawei HQ

Jockeying for position in the yet-to-be-real 5G market continues, with Huawei announcing that it's going to demo a new air interface at Mobile World Congress in March.

The Chinese giant will be showing off techniques it calls Sparse Code Multiple Access (SCMA) and Filtered-Orthogonal Frequency Division Multiplexing (F-OFDM).

In a canned release, the company says it has “proved that the new air interface design can effectively improve spectral efficiency, increase connectivity, and reduce latency, thus facilitating the deployment of customised scenarios applied to the Internet of Things (IoT) and for high bandwidth-consuming scenarios such as virtual reality.”

The company also says its full-duplex air interface's multi-path fading cancellation helps deliver 200 per cent better spectral efficiency than current systems, “laying a solid ground for future unification of TDD and FDD spectrums” (frequency-division duplex and time-division duplex respectively).

Of course, none of this would be any good if Huawei were the only player to use a technology – and there's the rub.

Along with all the other big names in the mobile market, the Chinese vendor wants its technologies to be accepted into whatever the standards bodies eventually adopt for 5G.

Having devoted, it says, $600m to development work between now and 2018 – along with 300 researchers in its 5G labs – Huawei would like a payoff. Getting “reasonable and non-discriminatory” royalties from having a standards-essential patent would be a darn good start. ®
