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.

GSM Frequency Ranges
There are four main GSMs versions exist based on the band used: GSM-900, GSM-1800, GSM-850 and GSM-1900.
1)GSM-900 makes use of 890-915MHz to send information and 935-960MHz to receive information.
2)GSM-1800 makes use of 1710-1785MHz to send information and 1805-1880 to receive information.
GSM-1800 is called as Digital Cellular System (DCS) and it is commonly used in Personal Communications Network. GSM-1900 is called as Personal Communications Service (PCS-1900). PCS-1900 standards are integrated with that of GSM/DCS specifications resulting in a specification for GSM/DCS/PCS based on the Release 98 Series of GSM Specifications.

3. Wear an airtube headset (not regular wired headset). The regular wired headset has been found to intensify radiation into the ear canal. The wire transmits not only the radiation from the cell phone but also serves as an antenna attracting EMFs (electromagnetic fields) from the surroundings

4. Don't put the cell phone in your pocket or belt while in use or while it is on. The body tissue in the lower body area has good conductivity and absorbs radiation more quickly than the head. One study shows that men who wear cell phones near their groin could have their sperm count dropped by as much as 30 percent.

5. If using the phone without a headset, wait for the call to connect before placing the phone next to the ear.

6. Do not use the cell phone in enclosed metal spaces such as vehicles or elevators, where devices may use more power to establish connection. The metal enclosure also acts as a Faraday cage that traps the radiation and reflects it back onto the occupants.

7. Do not make a call when the signal strength is one bar or less, which means the phone must work harder to establish a connection.

8. Purchase a phone with a low SAR (Specific Absorption Rate). Most phones have a SAR level listed in its instruction manual. The SAR level is a way of measuring the quantity of radiofrequency (RF) energy that is absorbed by the body. The lower the number the better. (Be aware, however, that studies with RF hundreds of times lower than current SAR limits still show biological effects.)

E-GSM, the extended GSM make use of uplink frequency range 880MHz - 915 MHz and downlink frequency range 925MHz - 960MHz. The GSM specifications also define railways GSM (R-GSM) which make use of uplink frequency range 876 MHz - 915 MHz and downlink frequency range 921MHz - 960 MHz. All these specifications are called as GSM-900.

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.
