Cambium Networks is pleased to announce the Cambium XE3-4 for Wi-Fi, Wi-Fi 6, and Wi-Fi 6E networks. This is an innovative and unique access point with software-defined radios.
XE3-4 Capabilities At-a-Glance:
- • Software-defined radio supports 5 GHz or 6 GHz band operation with 4×4 streams
- In 6 GHz band, supports 802.11ax
- In 5 GHz band, supports 802.11a/n/ac/ax
- Fixed band 5 GHz radio supporting 802.11a/n/ac/ax with 2×2 streams
- Fixed band 2.4 GHz radio supporting 802.11b/g/n/ax with 2×2 streams
- 1 x 2.5 GbE and 1 x GbE uplinks
- Integrated BLE radio
- 802.3bt or 802.3at PoE Powered Device
The Cambium XE3-4 can be managed by Cambium’s XMS-Cloud, cnMaestro X (cloud or on-premises), cnMaestro Essentials (cloud or on-premises), or Swift applications. This management flexibility allows the XE3-4 to be tailored to meet end-user or managed service provider requirements with application policy controls, location services, BYOD security segmentation, or part of a wireless fabric architecture spanning outdoor broadband, Ethernet switching, and enterprise Wi-Fi.
XE3-4 is supported by any of the cnMatrix Ethernet switches. To match the high aggregate throughput of the Wi-Fi 6 radio + Wi-Fi 6E radio, the EX2016M (SKU:MXEX2016MxPA00) with multi-gigabit Ethernet interfaces is recommended.
Key Features of the XE3-4
- Software-defined radio: A software-defined radio (SDR) on the XE3-4 can be configured for operation in either the 6 GHz band or 5 GHz band. The SDR function can be enabled when managed by XMS-Cloud or cnMaestro™. When managed by Swift app-based management, the SDR radio is locked to the 6 GHz band, thus providing a tri-band operation in any management model.
- Wi-Fi 6: Wi-Fi 6 is the Wi-Fi Alliance certification standard for the IEEE 802.11ax protocol. The full capabilities of Wi-Fi 6 are covered elsewhere, but a short summary will highlight the key value. The most often mentioned feature of Wi-Fi 6 is OFDMA (Orthogonal Frequency Division Multiple Access). OFDMA allows individual transmitters in the network to be assigned a sub-carrier frequency, called a Resource Unit (RU). The assignment is performed by the wireless access point, dynamically, at each transmit opportunity. Thus, the network can be called deterministic because the AP is in charge of telling all the client devices when and how to transmit and receive wireless data frames.
OFDMA delivers a high-efficiency network by allowing multiple devices to transmit at the same time. The result is like a delivery truck packed with small, medium, and large packages.
Wi-Fi 6E in the 6 GHz Band: Regulatory domains across the globe have opened the 6 GHz band for use with Wi-Fi networks under rules designed to protect incumbent users of the 6 GHz band. Each regulatory domain is different, but there are basically two sets of frequencies supported for Indoor Wi-Fi networks under Low Power Indoor (LPI) rules – 1200 MHz and 500 MHz. In total, the 6 GHz band adds 1200 MHz to the frequencies available for Wi-Fi networks. The chart below shows the typical bandwidth available. Actual values are dependent on the regulatory domain. Always consult local regulatory domain rules for details in your country or region. Wi-Fi 6E regulatory rules define three classes of access points and Wi-Fi networks. Very Low Power (VLP), Low Power Indoor (LPI), and Standard Power (SP). XE3-4 is designed to support all three modes, subject to the national standards and regulatory domain requirements.
