Millimeter wave radio link

With the growing use of local area networks, video teleconferencing and high speed, point-to-point communication, users are faced with need for quick, simple connectivity. The radio links in personal communication systom, (PCS) will likely share existing UHF and L-band at the beginning, however, they will soon become the limitations for rapidly expanding of PCS´s because these frequency bands are so congested that it is hardly possible to contain new services. This is the reason why higher frequencies - millimeter waves MMW are considered.
