![]() ![]() Thus the signal to noise ratio (SNR) stays the same. As you amplify the signal, you also amplify the non-signal (noise). Note that simply amplifying the signal received by the antenna does not help. The directional characteristics of an antenna, combined with its physical size, give it what is called an effective capture area - or the "effective aperture." These are known as "directional" antennas. Other characteristics can make an antenna better able to capture energy from one direction compared to another. In general terms, the bigger the physical size, the more RF the antenna captures and converts into physical electrical signals. You can increase received signal by increasing the endpoint transmitter power (which we've already noted that you can't do) or by increasing the amount of endpoint signal captured by the AP.ĪPs capture signal with antennas. You can do that only by increasing the amount of received signal. If you want to improve two-way communications, you'll have to give the AP an ability to hear better. You'll create an alligator AP - all mouth and no ears. When your AP stops transmitting and tries to listen, it's going to hear the interfering signals at exactly the same amplitude as its hearing them now. If all your client devices can hear the AP, you do not have communication unless the AP can hear the devices. Crank the AP power up to 1,000W if you want - that tablet isn't going to also increase its power to 1,000W. Next, consider who your APs are talking to. ![]() So the interfering RF environment isn't going to change. An interfering signal from outside the system doesn't "go away" based on the presence or absence of another signal - no matter how strong or weak. Unfortunately, this isn't how RF (radio frequency) works. They all have basically the same functions on the transceivers.īut without confusing the issue at hand, I'm basically asking what is the best practices to consider regarding wifi channel usage for wifi APs in an ideal mesh typology? I haven't decided yet on whether they will bridge to each other or if I will connect a LAN to each one. I've wanted to create a wifi Mesh for quite some time. I have several sets of APs and wifi routers I could use, But I am considering using the Linksys LAPN600 I have sitting around collecting cob webs. No other wifi management system is in place. Also they are positioned to completely cover office space with a wifi signal. Keep in mind all the APs have the same SSIDs and password login. Or should I set all the APs on a static channel for example Channel 11 (on the 2.4 GHz band) ? ![]() Should I set static channels on the APs giving each AP a different channel? What I'd like to know is should I leave each AP to decide which channel is best (Auto selecting the channel as most wifi devices do)? I'd like to setup 4 wifi APs in the office to create a massive antenna array to block out any competing RF signals stepping on our location. ![]()
