Key Points About The Technology
Connections
Connections between the Base Station and Subscriber Units can be either Line of Sight or in some frequency radio systems Non-Line-of-Sight where link budgets permit.
Wireless
Point To Multipoint links are installed to reduce the cost of infrastructure and increase the number of CPE's and connections.
Point To Multipoint systems can be implemented in Licensed, Semi-licensed or Unlicensed frequency bands depending on the specific application.
Links
Point to Multipoint links are very popular in the wireless ISP (internet service provider) and campus type environments. It is also commonly used in wireless CCTV applications.
Antennas
The Base Station may have a single Omnidirectional Antenna or multiple Sector Antennas which are often used to increase both range and capacity.
