Wireless networking technologies lend themselves to providing both backbone transmission capacity – for example by interconnecting unbundled telephone exchanges – and last mile connectivity. Wireless complements traditional wireline technologies by plugging gaps in the wired topology, offering additional resiliency in the form of back-up capacity in network backbones, and as a substitute when wireline costs are prohibitive.
Microwave
The term ‘microwave’ refers to electromagnetic energy having a frequency in excess of 1Ghz (billions of cycles per second), corresponding to wavelengths shorter than 30 centimetres. The technology is harnessed as typically the most common method for wireless backhaul, at speeds up to 622Mbps.
Selecting the appropriate choice for wireless backhaul technology involves numerous considerations including network capacity, desired data transmission speed/s, and electromagnetic interference.
OFDM
OFDM radio technologies provide the ability to deliver cost effective broadband connectivity to hard-to-reach locations, and in terrains where no line-of-sight exists between the radio base station and network end-points.
Updata is fully-versed in both licensed and unlicensed radio deployments, and can advise on the most appropriate deployment options.
Operating within the ‘lightly-licensed’ 5.8GHz spectrum, transmission speeds of up to 100Mbps are possible using OFDM on point-to-point links. Licensed OFDM frequencies begin at 7GHz and higher
