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.[6][7][8] Publicly traded on the NASDAQ stock exchange, it spun out of Motorola in October 2011.[9][10][11]

Key Information

Products

[edit]

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.[12] 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.[13] As of 2021 the company has shipped 10 million radios.[14]

Products are available in point-to-point and point-to-multipoint configurations. Its cnWave fixed wireless solution provides multi-gigabit throughputs.[14] 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.[15] Campgrounds, RV parks and holiday parks have deployed Cambium Networks' fixed wireless and Wi-Fi for high-speed connectivity.[16]

Enterprise Wi-Fi and Switching

[edit]

Cambium Networks also manufactures Wireless LAN (WLAN) Wi-Fi access points including Wi-Fi 6E and intelligent switches along with cloud-management systems.[17] In 2022, Spectralink added interoperability with Cambium Networks access points and Wi-Fi phones and handsets as part of its enterprise wireless certification program.[18]

History

[edit]

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.[19] In July 2019, Cambium acquired Xirrus from Riverbed Technology.[20] In June 2019, the company listed on the NASDAQ Stock Exchange in an initial public offering that raised $70 million.[21] WISPA network operator members voted Cambium Networks the “Manufacturer of the Year” from 2017-2020.[14]

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).

Typical setup

[edit]
A 2.4 GHz Subscriber Module with Reflector Dish
A 5.2 GHz Subscriber Module with a 'Stinger' Passive Antenna

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.[22] 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.

Comparison with other wireless networking systems

[edit]

While Cambium offers products that support the Wi-Fi protocols (mostly the cnPilot range and the products from their Xirrus acquisition), most of their outdoor, long-range products function exclusively with the proprietary TDMA Canopy or Cambium protocols on custom FPGA code. These are heavily optimized for GPS synchronization, frequency re-use, low latency and long distances / high interference survival.[23]

The versions of this protocol include:

  • PMP100 - FSK based system which works on 8Mhz (on 900mhz) or 20Mhz channels (on 2.4Ghz, 5Ghz). Offers <5 mbps on 900mhz or <14 mbps on the other frequencies.
  • PMP320 - WiMAX 802.16e-based system, which came from their Nextnet acquisition therefore has architecture differences from most of the other products. 3Ghz band only and 5/7/10mhz channels, offers up to 45 mbps throughput at the 10Mhz channel size but that was rarely achieved.
  • PMP400 - first OFDM-based product, 10Mhz channels, up to 20 Mbps speeds. 5ghz band only.
  • PMP430 - evolution of OFDM, channel size 5/10/20Mhz, up to 50 Mbps speeds at the largest channel size. 5ghz band only.
  • PMP450 - large family of OFDM products. 900Mhz, 2.4Ghz / 3Ghz / 5Ghz band coverage, 5-40Mhz channel sizes. Can do 200 Mbps+ at 40Mhz channels. The Medusa MU-MIMO Access points allow multiple streams simultaneously, therefore can achieve 1 Gbps+ of throughput split between multiple customers in a 40Mhz channel.
  • "Orthogon" protocols - these came from the Orthogon Systems acquisition. The protocols have a large number of subcarriers allowing powerful non-line-of sight abilities. The 5Ghz-only product families include PTP400 (OS-Gemini), PTP600 (OS-Spectra), PTP300/500 and PTP 650/670/700. These families are not protocol-compatible with each other, and some different products have intra-family protocol compatibility limitations. In comparison, the PTP250 was an early Wi-Fi chipset attempt and the PTP550 is an ePMP-based product.
  • ePMP - this is the value line, unlike the others these are based on commodity Wi-Fi chipsets, with the advanced protocol implemented in software. The PPS numbers are lower but still far in excess of competitive Wi-Fi-based products. It maintains the advantages including GPS synchronization and frequency re-use. They offer 10/20/40/80Mhz channel size support, with 160Mhz in development.

These products are fixed wireless technology. Canopy protocol products have many advantages over Wi-Fi and other wireless local area network protocols:

  • Transmission timing is explicitly controlled, so that all access points (AP) on all towers can be synchronized by cluster management modules (CMM) to prevent interference. APs of the same band can be placed right next to each other, and back-to-back units can use exactly the same frequency.
  • Designed for wireless internet service provider (WISP) use; polling-based (prevents one subscriber module from "hogging" bandwidth), excellent interference rejection and easy management.
  • Simple to install and configure.
  • TDMA system and optimized radio design allowing long-range communications, often 10 km+

Their main disadvantages are:

  • Proprietary
  • Less reliable than wired systems

Technology and Applications

Network Setup and Architecture

Cambium Networks' point-to-multipoint (PMP) systems typically employ access points (APs) equipped with sector antennas featuring 60- to 90-degree beamwidths to achieve comprehensive 360-degree coverage in fixed wireless deployments. For instance, four 90-degree sectors or six 60-degree sectors can be arranged around a central tower to serve a full circular area, with each AP connecting to multiple subscriber modules (SMs) that act as client endpoints for end-user devices. These SMs, often integrated with directional antennas, enable reliable connections from remote locations to the network core. Effective operational ranges in PMP configurations vary by frequency band and environmental factors but commonly extend from 3.5 to 15 miles, supporting delivery in both line-of-sight and near-line-of-sight scenarios. Power delivery relies on a proprietary (PoE) implementation, which operates at voltages such as 48-56 VDC and is incompatible with the IEEE 802.3af standard, necessitating Cambium-specific injectors and cabling up to 100 meters in length. The deployment process begins with mounting APs on towers or poles using brackets and clamps, connecting them via Ethernet to the for data and . are installed on customer premises, typically on rooftops or walls, and aligned to the AP using built-in diagnostic tools like signal strength LEDs, audio alignment aids, and web-based interfaces for and adjustments to optimize link quality. Grounding and surge protection are essential during installation to ensure reliability in outdoor environments. Cambium's ONE Network exemplifies a layered that integrates backhaul links, PMP access layers, access points, and Ethernet switches to provide seamless end-to-end connectivity across rural and urban settings. This unified approach supports scenarios like multi-gigabit delivery over 2 miles in urban areas, such as Perth, , where 60 GHz backhaul combines with for high-density coverage. Provisioning and management occur through cnMaestro for centralized configuration.

Protocols and Standards

Cambium Networks utilizes proprietary protocols, notably the Canopy (Time Division Multiple Access) system inherited from its legacy Canopy platform, in products like the PMP 450 and ePMP series for point-to-multipoint (PMP) deployments. This protocol organizes data frames in synchronized time slots to coordinate access between access points and subscriber modules, supporting up to over 200 Mbps throughput per sector as of 2025. A key feature is GPS synchronization, which aligns transmission timing across multiple access points to enable frequency reuse (e.g., 2-channel plans) and minimize self-interference, allowing efficient spectrum utilization in collocated setups. The company's systems comply with standards across variants, including 802.11n, 802.11ac Wave 2, and 802.11ax (/6E), ensuring in enterprise and broadband applications. For European markets, products adhere to ETSI EN 301 893 specifications, which govern 5 GHz RLAN operations including (DFS) and transmit power control (TPC) to mitigate interference. Operations occur in unlicensed bands such as 2.4 GHz, 5 GHz, 6 GHz (with Frequency Coordination in supported regions), and 60 GHz, facilitating deployment without spectrum licensing. Advanced features include dynamic spectrum access via Cambium's Dynamic Spectrum Optimization (DSO), which automatically scans and selects optimal channels in point-to-point links to adapt to environmental changes and maintain link reliability. platforms incorporate MU-MIMO (Multi-User Multiple Input Multiple Output), enabling concurrent downlink transmissions to up to eight clients for improved in dense scenarios. Low-latency modes, such as ePTP (enhanced PTP), achieve 2-3 ms round-trip times under favorable conditions, supporting real-time applications like video surveillance. Protocol evolution reflects a shift from the TDMA-centric Canopy architecture, optimized for interference-prone PMP networks, to hybrid approaches in newer solutions. The cnWave 60 GHz and 5G fixed wireless platforms integrate OFDMA (Orthogonal Frequency Division Multiple Access) alongside 802.11ay standards, enabling multi-user resource allocation for gigabit speeds and up to 3 Gbps sector throughput while maintaining backward compatibility with legacy TDMA elements in mixed deployments.

Comparisons and Advantages

Cambium Networks' fixed wireless solutions, such as the PMP 450 and ePMP platforms, leverage proprietary (TDMA) protocols that provide superior interference handling compared to and LTE standards. The cnMedusa technology in PMP 450 enables fast and interference cancellation, allowing for higher capacity in dense environments—up to 600 Mbps per sector—while LTE typically achieved around 130 Mbps aggregate throughput per sector as of 2021. Additionally, these TDMA-based systems deliver latencies under 5 ms in ePTP mode, outperforming the higher latencies often associated with cellular handoffs in LTE and . However, Cambium's offerings lack the broad device compatibility of cellular standards, as they require dedicated rather than supporting standard mobile handsets. This makes them particularly suited for fixed rural access, where they excel over mobile-focused technologies by providing stable, high-throughput connections without the overhead of mobility support. In comparison to wired fiber solutions, Cambium's fixed wireless technologies offer significant advantages in deployment speed and cost for last-mile connectivity. Networks can be established in hours or days using point-to-multipoint architectures, contrasting with the weeks or months required for trenching and installation. Cost savings can reach up to 20% or less compared to trenching , with wireless options avoiding extensive expenses. Ranges exceeding 10 km are achievable with sub-6 GHz products like cnWave, enabling broad rural coverage without the physical of . Drawbacks include greater susceptibility to weather-related signal , such as , and the absence of native gigabit symmetric speeds in lower-frequency bands; achieving multi-gigabit symmetry typically requires mmWave deployments like the 60 GHz cnWave series. Relative to competitors like Ubiquiti and Mimosa, Cambium's platforms emphasize scalability through features such as GPS synchronization, which minimizes self-interference in multi-sector deployments and supports networks with thousands of users. The cnMaestro cloud management platform further enhances large-scale operations with centralized monitoring and optimization, providing more robust tools than Ubiquiti's simpler interfaces or Mimosa's spectrum-focused designs. In 2025, the Force 4518 and Force 4616 series introduced low-cost subscriber modules that undercut competitor pricing while delivering 1 Gbps throughput via 1024-QAM modulation—these 5 GHz and 6 GHz models support high-density environments with improved spectral efficiency and easier scalability for WISPs. Cambium Networks primarily targets wireless internet service providers (WISPs) in underserved rural and suburban areas, where its solutions bridge connectivity gaps without the infrastructure demands of urban fiber replacements. This niche focus allows WISPs to deliver reliable to communities lacking traditional wired options, as demonstrated in deployments providing high-speed access to remote regions.
