Research results of the impact of spatial and polarization value of the antennas on network capacity of wireless channels standard IEEE 802.11
Keywords:network capacity, metal-lamellar cylindrical lens, polarization
We consider the experimental results and calculations of the impact of directed properties of the antennas with the range of 2.4 GHz on solving the problem of the “last mile” in wireless technology standard IEEE 802.11b. In the experiments to focus energy in a given subscriber direction there are applied electromagnetic accelerating metal-lamellar cylindrical lens along with the standard antenna of wireless access point and at the signal reception point the power of signal was speed up on 5–7 dB, and network capacity was increased on 4%.
The best results of using polarization properties of antennas to enhance the information capabilities of radio systems of IEEE 802.11n standard in premises with difficult location and orientation of ray redirecting surfaces were obtained for the combination, where on the receiving and transmitting sides there where mounted three pulsators accordingly: the vertical and two next angularly –π/4 and π/4 relative to the central one. The gain of network capacity has increased in 2.4 times in comparison with the use of three parallel pulsators.
