 No software support is needed for the GW16081

+=== 9 radio test
+
+GW640x and GW630x J9 slot can be replaced with PCI-e Expansion adapter, contact !sales@gateworks.com for details.  Attaching a GW16081 at that site allows 9 and 8 radios can be populated on those boards respectively.
+
+A limiting factor when using Ventana was the address space, Newport has a much larger address space therefore allowing numerous modern devices to be working simultaniously.  For a test 9x GW17032 (WLE900VX, ATH9k) radios were brought up as access points.  This configuration can be achieved very simply using the following steps. 
+
+- Attach radios to both boards, attach expansion board to SBC. 
+- Attach barrel jack power to expansion board.  The radios are going to draw more power than can be can be provided through the mezzinene expansion header.    
+- Attach POE, or barrel jack power to SBC.
+- Using your perfered method install your perfered BSP, during this testing Ubuntu Bionic with 4.20 kernel was used. 
+- Boot Bionic download necessary software and scripts 
+ - 
+{{{ 
+apt-get update
+apt-get install hostapd
+}}}
+ - Download hostapd-conf script
+{{{
+wget https://raw.githubusercontent.com/Gateworks/meta-gateworks/master/recipes-support/hostapd-conf/hostapd-conf/hostapd-conf
+}}}
+ - Add execute permission
+{{{
+chmod +x hostapd-conf
+}}}
+- Configure radions as AP's
+ - For a full overview see [wiki:/wireless/wifi#hostapd here]
+ - Verify available channels 
+{{{
+./hostapd-conf wlan0
