I will show you the methods of expansion of the Wi-Fi coverage area radio. Number of access point depends on the performance of its emissions. Several versions of Wi-Fi standards have extensions.

Different radio signals and other wireless networks may conflict with your WiFi signal. This could lead to a reduction in coverage. Several obstacles, including reinforcing steel could even lead to complete loss of transmission signal from the black spot.

Radio coverage of an access point (BSS) is often not enough for many situations.

At the disposal of various methods of extending the wireless coverage:

1) Use the access point in repeater mode – Wireless Distribution System. If your distribution system or wireless access point in repeater mode, AP no spine. The connection to the backbone of the super-access point. The Ethernet port is the backbone. Repeater mode, Ethernet port of the PA has no transport.

You’ve Repeater AP, with super-AP, and if the client connects to AP Repeater, is extended.

Repeater mode disadvantage is a decrease of bandwidth – AP needs to receive and send packets on the same channel.

2) increase the power of access point. You can use the radio access area an increase in power AP. Performance reports from Access Point is directly proportional to the radio coverage area. If you have more power, the radio is greater coverage area.

Government regulates the highest return for the radios. Maximum power of 100 mW. Power, in general, access is reduced since the operation. If the Site Survey, you can maximum transmitted power.

Here is the procedure for optimal performance on AP:

- Make sure the AP maximum performance.

- Decrease power AP, until the high-bandwidth and constant

It could also be the lowest possible performance. Then, increase performance, to a maximum of consistency and bandwidth.

3) access points to distribute optimally. You can use the radio coverage area in good Site Survey. Distribution of access points is very important, the area of radio coverage.

You will be surprised, but also for many access points, bandwidth. You can congestion and incidents.

If you want maximum range, the position of access points overlap between the 15%. You can very large area with minimal cost, if you have any access points, with minimal overlap. Stations can move freely and roaming between access points when you use the same SSID on all access points into the environment.

Take a good planning and the right of access, distribution point, and you, with minimal side have better results.

4) The use of secondary-Access-Point non-overlapping channels. Using the access point AP-mode non-overlapping channels, you can cover much larger radio.

Use this method only if you can access the second backbone, wireless or part of the network. The disadvantage of this method is that the cable access network to the second point.

Advantage of this method is that it is easier to implement. It does not require much configuration. Only a basic configuration of the second access point.

Do not use overlapping channels, if the 2 points. If you are near, overlapping channels, could happen. This leads to poor connections and a lower margin.

Make sure that the distance between two points. If close, you can gridlock, and you lose the radio are.
