     93As WiFi has become an essential component of the communications infrastructure there are many applications that can take advantage of high radio count access points. Below is a brief list of benefits and advantages of high radio count access points:
     94
     95* Provide dedicated private and public radios on different frequency bands.
     96* Support both 2.4G, 4.9G (public safety) and 5.8G bands simultaneously.
     97* Utilize multiple radios with sectored antennas (ie. 45 degree) to increase both transmit and receive ranges. Note that using a high power radio only increases the transmit range so this doesn't provide any benefit when talking to standard clients (ie. cellphones, tablets, etc.).
     98* Monitor WiFi traffic on multiple channels/frequencies simultaneously.

    94101The Newport GW640x and GW630x boards are ideal SBCs for implementing multi-radio access points since the Octeon TX SoC has a highly optimized ARMv8 core that can process >11M packets per second and it additionally supports a large pool of PCI memory address space allowing it to support a large number of PCIe devices.

    96 The GW63xx and GW64xx boards both support up to 3x Mini-PCIe based radios on their own however Gateworks has allowed for the bottom right Mini-PCIe slot to be replaced with a PCI-e Expansion connector allowing the board to be stacked with the GW16081 Mini-PCIe Expansion Mezzanine. With this configuration the board can be setup to support up to 21x Mini-PCIe based radios!
     103The GW63xx and GW64xx boards both support up to 3x Mini-PCIe based radios by themselves however Gateworks has allowed for the bottom right Mini-PCIe slot to be replaced with a PCIe Expansion connector allowing the board to be stacked with the GW16081 Mini-PCIe Expansion Mezzanine. With this configuration the board can be setup to support 21x Mini-PCIe based radios!

    101108With a single GW16081 up to 9 radios can be supported with the GW63xx/GW64xx (2 on the SBC + 7 on GW16081). For even higher radio count applications a special version of the GW16081 is available with an additional stacking connector allowing up to 3 GW16081's to be stacked with the CPU board. This would allow up to 21 radios.
