Solution

Objective : Designing mobile application to control microwave over Internet.

Assumptions:We will be needing two microwave antennas, some long Ethernet cables, a couple of photographic tripods, a laptop, an old WiFi Route, and power. The radio is integrated in the antenna feed.

Interface Metaphors:

Set up the hardware

Mount the two antennas onto photographic tripods using the antenna-included hardware .Then align the two antennas at their prospective locations by pointing the antennas at each other. The shorter the distance, the less accurate you need to be.

Set up the access point network by connecting the included Power Over Ethernet injector to a power source near the incoming Internet router. Internet can be supplied by a normal domestic modem or router. Then connect an Ethernet cable from the POE injector to the Ubiquiti access point antenna, and from the POE injector\'s LAN port to a laptop with another one of the Ethernet cables.

Assign a static IP address to the laptop. Use the address provided by the antenna manufacturer .it will be in the documentation. Then save the settings, open a browser and navigate to the IP address provided. The access point\'s dashboard will open. Enter the User ID and Password. Then open the Wireless tab, set the Wireless Mode to Access Point WDS and create a unique SSID.

Set the security to a preferred mode, like WPA2-AES or similar. Use PSK for authentication. Enter a key. Then choose Bridge from the Network tab and enter the network settings provided in the antenna\'s documentation.

Set up the station network by following the same steps that you performed with the access point, except that the wireless mode should be set to Station WDS, not Access Point WDS. Then lock to the access point\'s SSID that you set up earlier.

Deploy the access point by switch off the incoming Internet modem or router and POE. Then unplug the laptop cable and plug that cable into the Internet supplying router. Turn everything back on again.

Deploy the station follow the same deployment process as with the access point except plug the configuring laptop cable into a now nonstatic IP-addressed laptop or a configured 2.4 GHz household WiFi router.

Now at last perform the testing. Internet will be available on the laptop or WiFi network at the remote location.
