The 71-76 and 81-86 GHz bands (also known as “e-band”) are permitted worldwide for point-to-point communications. Wireless regulators in the USA, UK and many other countries have introduced “light licensing” schemes for managing this Ultra High Capacity Ultra High Frequency (UHCUHF) radio equipment in this band. | The Benefits of Light Licensing for 70-80Ghz Millimeter Wave Wireless Systems APPLICATION NOTE The 71-76 and 81-86 GHz bands also known as e-band are permitted worldwide for point-to-point communications. Wireless regulators in the USA UK and many other countries have introduced light licensing schemes for managing this Ultra High Capacity Ultra High Frequency UHCUHF radio equipment in this band. These innovative licenses retain the benefits of full interference protection that a wireless license guarantees but can be applied for in minutes and costs less than a hundred dollars per year. This is significantly faster and cheaper than traditional licensing making e-band an attractive alternative to existing licensed wireless technologies. The Light Licensing Principle Systems operating at the e-band frequencies have two unique characteristics not experienced by conventional lower frequency devices. Firstly the high operational frequencies of e-band systems make antennas highly directional meaning systems communicate via highly focused pencil beam transmissions. Secondly the 71-76 and 81-86 GHz frequency bands are configured as two single channels meaning traditional frequency planning does not need to be considered. Together these two unique properties of e-band systems enable operators to realize networks with a high degree of frequency reuse even configuring links close to one another without interference concerns. The national wireless link regulators and administrators in many countries have recognized that these characteristics vastly simplify the licensing process. With no frequency coordination and much simplified interference analysis the burdensome traditional link licensing schemes are not necessary. Innovative streamlined processes have been introduced that enable links to be applied for in real time and interference analysis and link approval to be realized in minutes. Because administration is vastly reduced the cost of such light licenses has been .
