Some proprietary applications like long-distance microwave network links use point-to-point technology with narrowband radios and highly directional antennas. However, this technology is not common enough to produce any significant research into its vulnerabilities, and anything that was developed would have limited usefulness. So the chapter focuses on point-tomultipoint systems, the two most common of which are the family ...
