5. RF Test Method and Specifications
A. Test Method
Antenna Orientation
See above diagram for orientation for maximum RF range
performance
Indoor Range*
~15 m line of sight
Tx Setup
~1.3 m high, stationary, powered with 6V DC 400mA power
adaptor
Rx Setup
~1.2 m high, mobile, powered with 4 AA batteries
Office Space
Open design with some cubicles
Office footprint
26 m x 19 m
Notes
• Antenna orientation is important to overall RF range
performance.
• Layout of the testing space affects RF performance.
Reflections of the RF can cause interference.
• Obstacles such as the tester’s body, walls, and cubicles can
affect the range, wherever possible keep node antennas in
line of sight.
• Other RF devices operating in the 2.4GHz spectrum can
affect the RF performance such as microwaves, wireless
routers, and other equipment sharing the 2.4GHz band.
*Range stated is as measured in Eleven Office Space at 20ms latency.
