1 1 Leaky Feeder Cable A distributed antenna solution for WiFi Steve Mace Solwise Ltd

2 2 Introduction –WiFi and walls –Shadows Leaky Feeder Cable –What is it? –Construction Tests and application

3 3 Doesnt go through walls

4 4 Creates Shadows

5 5 Distributed Antenna

6 6 Cable Construction Polyethylene Jacket Copper foil outer conductor Foamed PE dialectric Hollow copper inner conductor Loss 0.16dB/m

7 7 Connectors

8 8 Slots in the Shielding Slots set at wavelength multiple –75-500MHz – MHz – MHz Terminator for reflections

9 9 Physical Characteristics

10 10 Gain typically dBi Coupling Loss quoted at typically 60dB at 2.4 GHz. This is the ratio of signal power going into the cable over the power of the received signal at 2m. So if you have 20dBm going in then the signal at 2m would be about -40dBm Compared to normal 2dBi rubber duck which, at 2m with a 20dBm signal power would be -24dBm. Test Results

11 11 Installation Discussion Make sure cable is orientated correctly and at least 4 inches from the wall AP with single run –c. 50m –Drop of 8dBm AP driving two runs c. 100m Boosters –Careful with maximum input
