Signals to profit from diversity within the channel as well as penetrating through concrete and glass

Huawei and Vodafone (the world’s second-largest mobile communications company) announced the successful trial of 2 Tbit/s wavelength-division multiplexing (WDM) fiber-optic transmission technologies on Vodafone’s live network. The field trial achieved 2 Tbit/s transmission capabilities on the 3325 km length huawei access network, a data-highway capacity 20 times over current commercially deployed 100 Gbit/s systems. This could produce advanced optical transport systems with capacities far beyond the present 100G technology, says Huawei.

Microwave transmission, an essential solution for mobile backhaul networks through the years, struggles in order to meet the need for multi-Giga bandwidth at long distances. Etisalat Misr, while using Huawei Super Dual Band microwave solution, has achieved 6.19 Gbps spanning a relatively cross country (3.37 km) link inside Alex region, applying state-of-the-art features (EPLA, AM and QoS) that stretch the rewards from the E-Band equipment.

Huawei’s Super Dual Band is undoubtedly an innovative solution, which bonds the conventional frequency (6-42 GHz) along with E-Band (71-86 GHz) within a unique manner, offering increased protection via special link aggregation techniques and advanced Quality of Service mechanisms. The Super Dual Band solution combines cross country benefit of traditional frequencies together while using large capacity benefit from the E-Band, ensuring efficient multi-Giga transmission.

Cohere says OTFS results in a two-dimensional take a look at the delay and signal fading of any wireless channel. It spreads information across serious amounts of frequency, that permits signals to learn from diversity within the channel whilst penetrating through concrete and glass, as well as achieve high amounts of immunity to fading, multipath and also other signal impairments at thunder-link.

In its early tests it trialled its technology among tall buildings and mountains along with moving vehicles, and asserted the OTFS radios never faded, even over distances above four kilometers, as OFDM ones might have done. A minimum of 4bps/Hz was achieved in 10 MHz of spectrum inside the 3.5 GHz band, driving speeds of 120Mbps to 320Mbps. The company’s initial trials used currently available 2×2 or 4×4 MIMO antenna arrays however its roadmap would be to produce Massive MIMO radios with 64×64 arrays, also to move up to your millimeter wave bands.
