High capacity WLAN access point architecture is described layered above a MAC layer of a standard WLAN protocol stack. Methods for forming orthogonal beams to deliver downlink information to a plurality of mobil
Accordingly, a first aspect of the invention concerns a radio frequency (RF) multi-antenna access point enhancement circuit. The circuit includes a multi-antenna signal processing circuit situated in a first access point and adapted to (a) operate simultaneously with a first baseband processor, so...
To achieve this pattern, the access point should be mounted clear of any obstructions to the sides of the radiating element. If the mounting location is on the side of a building or tower, the antenna pattern is degraded on the bu...
It is strongly recommended not to install antennas directly on the router or access point (AP), unless the router or AP is specifically engineered to directly mount the antennas. Products that are engineered for direct mounting of ant...
The conventional GPS monitoring methods, where a permanent GPS receiver must be located at each point, have significant limitations of the cost. A new approach that a single GPS receiver links multiple antennas mounted at the monitoring points, has been employed to solve these problems in this ...
Moreover, the feed point of each antenna was modeled as a port (micro coaxial) boundary condition. The E and H field satisfy the Sommerfeld radiation boundary condition. These equations can be hardly analytical solved; therefore, they are solved by numerical methods. Due to an EM field that...

摘要: In this paper, we propose and optimize a low-complexity precoding scheme for multiple antenna cognitive radio networks. In a cognitive network, a secondary transmitter is allowed to access the spectrum of the primary network only if the interference ......
An access point is generally a fixed station that communicates with the user terminals and may also be referred to as a base station or some other terminology. A user terminal may be fixed or mobile and may also be referred to as a mobile station, a wireless device, a user equipment (...
