You need to keep in mind several objectives when setting up wireless communications networks.
For one, when setting up wireless communications networks, you need to keep in mind the need for network security. The stuff that is communicated through the networks should be reasonably secure: and the networks you set up shouldn’t be very easy to penetrate and intercept. Even if they aren’t meant to be secure networks, there should still be reasonable security – knowing that there are probably some folks who will communicate using the networks thinking that the networks are secure.
Further, when setting up wireless communication networks, you need to keep in mind the need for proper capacity. In this regard, you should analyze the applications that the networks are to be used in, and ensure that the networks are adequate for those uses. The idea is to avoid ending up with the sort of network that buckles under the smallest hint of pressure. Thus, once you have figured out the demand for the wireless network you are setting up, you should add a small buffer and create a network with a slightly higher capacity — to cope with any unforeseeable needs.
Further still, when setting up wireless communication networks, you need to keep in mind the need for stability and resilience. The wireless networks you end up with shouldn’t be of the sort that is easily messed up by slight changes in weather. You should be aiming to come up with networks as good as those of companies like AT&T: networks that remain (largely) stable even in the midst of the most adverse weather conditions.
