Pinyon Technology Unveils New WiMAX Tri-Band Antenna Based on AirWire Technology

Pinyon Technologies announced that it has unveiled its new WiMAX (News - Alert) Tri-Band antenna, which is based on the Reno, Nevada, company’s AirWire technology.
The antenna supports WiMAX market around the world.
Pinyon’s AirWire technology is tailored for WiFi (News - Alert), WiMax, Bluetooth, UWB and mobile applications. It can be scaled to multiple frequencies, thereby making it adaptable to other wireless applications.
It is ideal for applications that require high gain in a noisy multipath environment and improves applications that require  high efficiency to maximize gain, customizable for precise radiation pattern control, real-time control for beam steering, current driven for scalability, and intrinsic band pass filtering to minimize noise.
According to a press release, the AirWire WiMAX Tri-Band antennas cover all of the licensed spectrum profiles for WiMAX, thereby facilitating OEM manufacturers to setup their equipments for any WiMAX market worldwide with the same antenna.
Officials with Pinyon said in a press release that AirWire WiMAX Tri-Band antennas can be customized for various form factors and can as well be accommodate with any connector type.
Covering the WiMAX spectrum profiles of 2.3 GHz, 2.5 GHz and 3.5 GHz, Pinyon’s latest offering maintains high gain across all the band profiles.
In addition, Pinyon’s new AirWire WiMAX Tri-Band antennas provide polar diversity, thereby adding an additional degree of antenna diversity to a wireless system that is equipped with MIMO spatial diversity. The polar diversity works to stabilize the link between the CPE and the WiMAX base station.
Many collinear and dipole antennas used on CPE can only transmit and receive vertically polarized signals, whereas Pinyon’s AirWire WiMAX antennas’ polar diversity feature uniquely overcomes this common shortcoming by detecting both horizontally and vertically polarized signals.
In addition, urban and indoor building environments produce horizontally polarized signal reflections. Generally, collinear or dipole antennas completely ignore such horizontally polarized signal reflections and consequently this reduces the chances of establishing a stable radio link resulting in substantially reduced throughput.
“Pinyon’s patented resonant slot AirWire antenna is specifically designed to operate in noisy environments through polarization diversity,” said Debashis Bagchi, CEO at Pinyon Technologies.  ”Polarization diversity allows AirWire to capture horizontally polarized signals which most existing antennas ignore.”
