Often we are required to expand coverage area wireless networks that already exist for all users, acapkali because there are some areas that have not touchable with a wireless service that is required, there are several techniques, among others, increase the Tx power wireless radio from the existing, and create a second repeater / WDS. Function of the repeater is a signal to strengthen the existing areas in order to expand its scope. The advantages of this repeater is he does not need a cable that is connected between the device with the radio repeater / access points source. A repeater receives a signal from the source access points ago mentransmisikannya back without changing the content of the content that already exists, so this is usually placed in the repeater halfway between access points and the farthest user, so this repeater useful to overcome the problems weakening the signal (atenuasi).
There are a few tips for the repeater:
- Telitilah buy wifi radio device, make sure he has the support or regular repeater feature called WDS (Wireless Distribution System). Not all wireless radio can be used as a repeater. WDS facilities usually recommended to use a fellow vendor / brand of the same or firmware. There is a regular feature called "Universal Repeater", this special feature, this facility can communicate with the access points even though the source is different vendor / brand. This facility does not have a lot of radio, sepengetahuan that we have only Senao ECB 3220, Edimax 7206, Zinwell ZW2194, and Minitar MWGAR.
-Posisikan repeater must receive a strong signal from the source access points, the stronger the signal is received the better of them can return ditransmisikannya
-Configure the access points of similarity with the repeater has a SSID and Channel is used.
We identify type-subnet IP Address between access points with the source repeater, should also use static IP Address.
WDS-To features, enter the MAC Address of each source with access points repeater.
-Update the firmware of each wireless radio in order to avoid the bugs that come later.
However, there is a need to consider the negative side of the repeater will reduce the throughput capacity of our wireless network is about 50%, because the repeater must receive and transmit packets of data back in one channel the same result will increase the capacity of the frame across a wireless network, especially if we use the repeater in the amount of the many, many more of the repeater penurunannya, because each repeater will menduplikasikan frame is sent.
