Multi-gigabit, MMW Point-to-point Radios: Propagation Considerations and Case Studies

Military surveillance and commercial high definition TV have joined carrier “backhaul” to drive development of lower cost, multi-gigabit millimeter-wave (mmW) radios, and the wildly differing system requirements, while challenging, are being met right ...
Communications at mmW frequencies offers several unique and very potent advantages as well as some sizable disadvantages. In order to develop cost-effective, high performance links a solid understanding of the issues and in particular how to benefit from the advantages while mitigating the disadvantages is crucial. Reduced hardware size...
