Getting high capacity internet connectivity to locations at short notice can be very tricky as generally there is a long lead time on any wired or fibre circuits. Using a wireless point-to-point link from a WISP (Wireless Internet Service Provider) can be a great solution if the conditions allow. As the name suggests these links are created using a special type of wireless adapter, typically from the roof of a building or a mast. In general these links require ‘line of sight’ between the two points and work at one of several frequencies to minimise interference. Depending on the location and distance speeds similar to optic fibre can be achieved.
Wireless point-to-point links are relatively expensive and do require some planning and assessment so are not suitable in all cases. There is also still a risk of interference causing problems even though special frequencies are used, however, for critical events this risk can be minimised by using two links from different locations running at different frequencies.
