Notes
1. Wireless card range depends on antenna performance, data transmission rate, operating frequency, physical obstructions, the weather, the colour of your socks and the wing movements of a butterfly in South America…
2. Distance figures provided for interest and entertainment only. Yawarra makes no warranty that you will be able to achieve similar distances with these wireless cards, and will not substantiate these claims under any circumstances. For typical operating distances, please refer to the manufacturer’s specifications (and Note 1).
