Russia Requires WiFi Registration
While WiFi wasn’t as broadly unlicensed in Russia as it is in most other industrialized nations, your can not find wifi antenna anywhere a state regulator exempted indoor use in certain bands from registration. The Mass Media agency apparently believes that it has the authority to compel this, although there’s some doubt by observers as to whether it really falls in their purview.

RF Antenna

How useful when you take of RF Antenna Products.
We provide a comprehensive range of RF Antenna Products that match the strict quality requirements of International market which has earned our company the distinct reputation of being a quality oriented Taiwan Exporter of RF Antenna Products. We are recognized as one of the leading traders in this sector due to our capability to supply impeccable RF Antenna Products to our customers. We laid our foot years back & ever since we are striving to deliver in our products innovation, competitive pricing & quality driven customer satisfaction.

AntennaDoor (one of the major RF antenna designer and OEM manufacturer in Taiwan) has started as a professional and prominent GSM/GPS supplier. With more than 10 years experience in OEM manufacturing and designing of RF antennas, our ambitious aim is to dominate Asia, Europe, and North America market and to become a front leader of RF antennas in these markets.

Global system for mobile communication (GSM) is a worldwide accepted standard for digital cellular communication. In 1982 a standardization group established named as GSM to create a common European mobile telephone standard that would formulate specifications for a pan-European mobile cellular radio system operating at 900 MHz.

To make a stealth technology successful, the plane would be of special design and have no surfaces that would reflect the radio waves. However, complete absorption of radio waves would not be possible by changes in the mechanical structure alone. This is completed with the help of a special coating on the plane. This coating is made from a partially conductive polymers that gives a conducting path to the radiowaves coming at it and emits the same frequency from the other end of the plane, thereby not reflecting or absorbing any of the oncoming waves and rendering the object invisible to radar.

Other mechanical designs involved in rendering the plane invisible to radars are:-
1) Shielded cockpits
2) No seams or gaps in the skin of the ship
3) No right angles on the tail surfaces
4) Having angled wings that direct the radar waves away from the surface rather than reflecting them.
5) Having its design by angular plates that reduce specular reflections and diffract radar waves into space
6) Screens cover engine ducts to prevent radar waves from entering, amplifying, reflecting and going back. These screens are similar to the screens used in your microwave ovens.
7) Serrated waves diffract radar waves away from the radar antenna.

GSM Specifications
Specifications for different personal communication services (PCS) systems are different among the different PCS networks. Description of the specifications and characteristics for GSM is as follows.

Frequency band:
For GSM the frequency range is varying from 1,850 to 1,990 MHz (mobile station to base station).

Duplex distance:
80 MHz is the duplex distance. Distance between the uplink and downlink frequencies is called Duplex distance.

We ensure high quality RF Antenna products by subjecting our RF Antenna products to stringent quality control measures during each stage of production and while dispatch.
