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 over the 3325 km length huawei access network, a data-highway capacity 20 times greater than current commercially deployed 100 Gbit/s systems. This could cause advanced optical transport systems with capacities far beyond the previous 100G technology, says Huawei.
Microwave transmission, a vital solution for mobile backhaul networks through the years, struggles in order to meet the need for multi-Giga bandwidth at long distances. Etisalat Misr, with all the Huawei Super Dual Band microwave solution, has achieved 6.19 Gbps spanning a relatively telephone long distance (3.37 km) link from the Alex region, applying state-of-the-art features (EPLA, AM and QoS) that stretch the pros from the E-Band equipment.
Huawei’s Super Dual Band is undoubtedly an innovative solution, which bonds the regular frequency (6-42 GHz) combined 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 long-distance 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 some time to frequency, that allows signals to learn from diversity inside the channel whilst penetrating through concrete and glass, as well as achieve high numbers of immunity to fading, multipath along with other signal impairments at thunder-link.
In its early tests it trialled its technology among tall buildings and mountains plus in moving vehicles, and stated that 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 within the 3.5 GHz band, driving speeds of 120Mbps to 320Mbps. The company’s initial trials purchase currently available 2×2 or 4×4 MIMO antenna arrays however it is roadmap is usually to produce Massive MIMO radios with 64×64 arrays, and move up towards the millimeter wave bands.
