context_page_description: Cambium Networks formerly known as Motorola Canopy is a fixed wireless networking system designed for wireless Internet service providers to provide Internet access. It uses relatively large antennas suitable for long range 900 MHz communication, typically over 1 metre long and 30 centimetres or more wide, and these are subject to vibration in wind or due to motion, so this is not a true mobile technology. An American software company, it provides wireless technology, including WiFi, Internet of Things, and fixed wireless broadband for enterprises. Publicly traded on the NASDAQ stock exchange, it spun out of Motorola in October 2011.
context_section_description: A typical Canopy setup consists of a cluster of up to six co-located standard access points (AP), each with a 60 degree horizontal beamwidth antenna, to achieve 360 degree coverage. The most commonly used APs are available in 120, 180, or 360 degree models for site-based coverage, thus decreasing the number of APs needed on a tower.  Also included would be one or more backhauls or otherwise out-of-band links (to carry data to/from other network occasions) and a Cluster Management Module (CMM) to provide power and synchronization to each Canopy AP or Backhaul Module (BM).
  Customers of the system receive service through subscriber modules (SM) aimed towards the AP. The SMs should be mounted on the highest point of a building to get a reliable connection; otherwise, Fresnel zone obstruction will weaken the signal. Under ideal operating conditions, the system can communicate over distances of 3.5 to 15 miles (5.6 to 24.1 km) depending on the frequency using equipment with integrated antennas. Network operators can opt to install reflector dishes or Stinger antennas or to use Canopy models that accept external antennas at one or both ends of the link to increase coverage distance.
  Most Canopy equipment receives its power using Power over Ethernet, however, none of its standards comply with IEEE 802.3af. A customer can query the status of their SM by viewing  URL 169.254.1.1/main.cgi with a web browser (unless the network operator uses a different IP address or has put the subscriber in a VLAN.
  In general, the 900 MHz version is more effective for use in outlying areas because of its ability to penetrate trees. However, it requires careful installation because of the easy propagation of interference on that band.  Other frequencies currently available are 2.4 GHz, 5.2 GHz, 5.4 GHz, and 5.7 GHz.
