What should tx power be

This cell displays the maximum power, in dBm, which is the same value as Amplitude dBm set in the Project Property node. Read only. Range: — This cell sets the minimum power for Tx Power Control, in dB.

The value must be smaller than or equal to the value set in Init Power. Calculation Example: Say the edge of the desired coverage area is 10 meters from the access point. Distance from AP meters 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 RSSI 4. URL Name. No results for undefined. Don't see what you're looking for? Ask a Question. This could cause other routers to use different channels as a result, freeing up the traffic on the channel your router is using, reducing congestion and letting your signal move quicker.

Improved speed and performance of your router if it is not turned up too high. Having the tx power level too high can make the client ignore the signal, because it simply does not have the same amount of transmit power as it is receiving. If too many people have their tx power level up too high, there would be extreme congestions on all bands as the signals are all being amplified. It can overheat your router by forcing it to work harder, making it burn out faster.

The client will be able to easily talk to the router when the tx power level is set lower. The client will be able to reciprocate the amount of noise it is receiving, making it easy to communicate.

You will not congest the channels for other Wi-Fi users in the neighborhood, helping keep the channels clear, making the internet work better for everyone. Too low of a tx power level could mean that the router will not reach the client it would like to, if the distance is too great. Neighboring routers could overpower your signal, gaining the attention of the client and leaving you behind. Neighboring routers may also not know that you are on that channel and use it as well, increasing the amount of congestion on that channel.

Just like you would with a traditional radio, you can move the antenna around to find a better signal. You can also get a high gain antenna that will improve your signal, but these are also more sensitive to movement so you will need to be careful when adjusting the position of the antenna. Normally, the antennas should be perpendicular.

Boosting the Tx power too much can actually hinder performance, because of the increased noise levels, as previously mentioned. This is not in all cases, but it works for most users. Also, be ethical. There are actually laws in place that limit the amount of power an Access Point or router can transmit. The reason for this is to stop wildly congested airspace in built up areas. Can you imagine an apartment block in a city where everyone just cranked up the power? There would be congestion on all bands and everyone would suffer.

It can increase the noise — When we say noise, we mean signal noise. Not actual noise that you hear! Increased noise drowns out the actual quality wifi signal that the data loves to be transported on.

When this happens it makes it more difficult for sending and receiving stations to communicate. This slows down data transfers, increases packet loss and affects coverage.
