Collinear Antenna Testing (indoors) Part 2, dual antenna

Round two of the indoor collinear tests. This time I used two of the 6Dbi antennas.


Below is the test data. Methodology is the same as before. Indoors tests run at 5, 10, 30 feet 1 wall, and 60 feet 2 walls. At each distance, the speed test was run 5 times. The five runs are averaged. The power settings ranged from 71mw default to 250mw maximum transmit power.

71mw

100mw

150mw

200mw

250mw

The bottleneck that arose at higher Tx powers on the single antenna were non-existant with this setup. At higher tx powers, the test device was able to approach 802.11g maximum bandwidth, which is 108mbps or 108000 kbps. It was also found that higher throughput was achieved at farther distances at higher tx powers.
