Case II:
Split Flexible Configurations Conference Room
A.
Factor
4 Antennas In Drop Ceiling
All of the transmitters are about the same distance to the closest antenna. The IMD product is small compared to the
IMD
transmitter signal. It meets the design rule.
Diversity
The antennas are separated so at least one antenna is always out of the null. This meets the design rule.
Line of Sight
All transmitters are in the line of sight of both antennas. It meets the design rule.
Cable Loss
Antenna combiners add 3 dB loss. Make sure the total loss in each run is less than 15 dB to meet the design rule.
Range Loss
All transmitters are close to at least one antenna and have about the same gain. This meets the design rule.
Transmitter
The setup is ideal, so set the power to 1mW for extended battery life and minimal interference with systems in near-by rooms.
Power
Rating
Expect excellent performance open or closed.
B.
Factor
2 Antennas On Back (or Front) Wall
The IMD from the transmitters close to the antennas can interfere with transmitters away from the antennas. Expect
IMD
dropout and hits.
Dividers often have metal cores which are radio opaque. Diversity is defeated when there is only one antenna in a room.
Diversity
Expect dropout and hits when the room is divided.
Line of Sight
No transmitter is in the line of sight of both antennas when the room is divided. It does not meet the design criterion.
Cable Loss
Long cable runs require expensive RG8 low-loss cable. Make sure the loss on each side is less than 15 dB.
Range Loss
Use low-loss cable for long runs. Make sure the loss on each side is less than 15 dB.
Transmitter
Use 10 mW output power to assure pick-up of the far transmitters.
Power
Rating
This system is prone to dropouts and hits open or closed.
