Cambium Networks Corporation is an American manufacturer of wireless telecommunications equipment, including Enterprise WiFi, Network switch, Internet of Things, and fixed wireless broadband and Wi-Fi for enterprises products for Internet access. Publicly traded on the NASDAQ stock exchange, it spun out of Motorola in October 2011.

Cambium Networks manufactures point-to-point backhaul, point-to-multipoint communication wide area network (WAN), Wi-Fi indoor and outdoor access, and cloud-based network management systems. In 2020, the company collaborated with Facebook to add mesh networking technology Terragraph that allows high-speed internet connections where laying fiber optic cable is not viable. As of 2021 the company has shipped 10 million radios.

Products are available in point-to-point and point-to-multipoint configurations. Its cnWave fixed wireless solution provides multi-gigabit throughputs. It includes both the original Motorola-designed products using the Canopy protocol and the PtP backhauls that were rebranded from Orthogon Systems, which Motorola acquired in 2006. Cambium Networks’ solutions are used by broadband service providers and managed service providers to connect business and residential locations in dense urban, suburban, rural and remote locations, including education and healthcare. Campgrounds, RV parks and holiday parks have deployed Cambium Networks' fixed wireless and Wi-Fi for high-speed connectivity.

Cambium Networks also manufactures Wireless LAN (WLAN) Wi-Fi access points including Wi-Fi 6E and intelligent switches along with cloud-management systems. In 2022, Spectralink added interoperability with Cambium Networks access points and Wi-Fi phones and handsets as part of its enterprise wireless certification program.

Cambium Networks was created when Motorola Solutions sold the Canopy and Orthogon businesses in 2011. Cambium evolved the platform and expanded it to three product lines: Point to Point (PTP) (formerly Orthogon), Point to Multipoint (PMP) (formerly Canopy) and ePMP. In July 2019, Cambium acquired Xirrus from Riverbed Technology. In June 2019, the company listed on the NASDAQ Stock Exchange in an initial public offering that raised $70 million. WISPA network operator members voted Cambium Networks the “Manufacturer of the Year” from 2017-2020.

The technology competes with WiMAX, LTE and other long range mobile products, but not effectively with wired Internet, which is capable of much faster speeds and does not have wireless relay round-trip delay. Competent Canopy implementations such as the Broadband for Rural Nova Scotia initiative however have demonstrated VoIP, gaming and other low-latency applications work acceptably over this system, and in areas of challenging weather including high wind conditions (which cause antennas to move and affect connections).

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.
