specifications wifi

4 Varin wifi specification consists of 802.11, namely: 802.11a, 802.11b, 802.11g, and 802.11n. B is the initial product specification Wi-Fi. Varian g and n is one product that has the highest sales in 2005.

The rest of the world, frequencies used by Wi-Fi, users permission does not apply to use of the local regulator (for example, the Federal Communications Commission in the US). 802.11a uses higher frequencies and therefore its range is more narrow, more equal.

WiFi is the most widespread type in the current USA market (based on the IEEE 802.11b / g) operates at 2,400 MHz to 2483.50 MHz. With so allow operations in 11 channels (each 5 MHz), based on the following frequencies:

1.  Channel 1 – 2,412 MHz;
2. Channel 2 – 2,417 MHz;
3. Channel 3 – 2,422 MHz;
4. Channel 4 – 2,427 MHz;
5. Channel 5 – 2,432 MHz;
6. Channel 6 – 2,437 MHz;
7. Channel 7 – 2,442 MHz;
8. Channel 8 – 2,447 MHz;
9. Channel 9 – 2,452 MHz;
10. Channel 10 – 2,457 MHz;
11. Channel 11 – 2,462 MHz

     Technically operational, WiFi is one variant of information and communication technology that works on computer networks and devices WLANs (wireless local area network). In other words, WiFiadalah certification trademark given to telecommunication equipment manufacturers (internet) working in WLANs and the networks already meet the required quality interoperates capacity. WiFidibuat-based Internet technology and developed a group of US engineers who work on the Institute of Electrical and Electronis Engineers (IEEE) based on technical standards numbered devices 802.11b, 802.11a and 802.11g. WiFisebenarnya devices are not only able to work on WLAN networks, but also in network Wireless Metropolitan Area Network (WMAN). Because the device with technical standards 802.11b WLAN devices are intended for use in the 2.4 GHz frequency, or commonly called ISM (Industrial, Scientific and Medical). Medium for devices that technical standards 802.11a and 802.11g devices intended for WMAN or also called Wi-Max, which works around the 5 GHz frequency band. A few articles specs WiFi
