Re: QoS

If you only setup QoS on the tower side, that means you only prioritise the client download traffic.

You don't actually control the client equipment upload, though you queue the client upload on your tower, and shape (prioritise) the upload to the internet.

Google for EIRP calculator.

XR5 = 600mwatt = 0.6 watt

ie you have to use a very tiny antenna :?

So rather use a larger antenna = higher db and a less powerful radio like RB52 which actually works much better (more stable) than XR5, even with lower signals.
