Distributed Antenna Systems-Das Installation-Das Installers DAS- System Design:With a proper understanding of what the systems needs to accomplish our wireless network infrastructure engineers are able to design an optimal layout of repeaters, antennas and components..Though often overlooked, we've found...
Because the antenna, mast, cable, and metal guy wires are all excellent conductors of electrical current, even the slightest touch of any of these parts to a power line completes an electrical path through the antenna and...
Low-Complexity Iterative Detection Algorithms for Multi-Antenna Systems Multiple input multiple output (MIMO) techniques have been widely employed by different wireless systems with many advantages. By using multiple antennas, the system is able to transmit multiple data streams simultaneously and within ...
Channel estimation, which plays a very important role in mobile WiMAX communications, is a tackle problem especially for multi-antenna systems due to limited number and irregular spacing of pilots. This paper proposes a channel estimation method based on the regularized low-pass filter with the aid...
1. An antenna system comprising: a plurality of planar antennas; a first set of at least two antennas from the plurality of planar antennas; a second set of at least two antennas from the plurality of planar antennas; a first reconfigurable circuitry coupling a first RF signal to at least ...
The antenna system in the MR-WND would have to implement multiple dual linear and orthogonal pair antennas, in a compact footprint for each MIMO order, and multiple such pairs for each radio. So long as sufficient isolation is maintained between all antennas, this MIMO scheme can be scaled ...
