WiFi - not working in concrete, around other wireless devices, etc.

Ever wonder why your Wireless Network (WiFi) doesn't work very well inside a concrete building... or even your phone, Blackberry, or other wireless device doesn't work very well inside a structure made of concrete? I could never pick up a radio station - or just barely - inside a concrete building, could you?

Some may wonder what exactly is this wireless signal that allows a computer to connect to the router that connects to the internet. All it is, as of this post, is a channel within the 2.4Ghz range (radio wave) that broadcasts and receives (just like a transceiver).

Concrete is a material that does not allow radio waves to travel through it very well.

Some buildings are made of concrete. The best thing to do is to get wireless access points which will allow the signal to travel to the gateway to the Internet (typically a router, modem, firewall, etc.).

Also, with too many wireless components (mice, keyboard, printer, etc., etc.), you may get interference between the devices, which will cause issues. If you have a wireless adapter which communicates to your wireless access point on a channel within the 2.4Ghz range, there is definitely a possibility that, if you have a 2.4 Ghz phone (as some phones are), the components will interfere with one another. What is the answer? The "relatively new" phones are DECT 6.0 phones should not interfere.

Keep all this in mind when you have a WiFi network.

After some extensive research, RIOTTech has found that there are not many IT solution providers who are willing to install WiFi networks in concrete buildings. Recently, RIOTTech did it in a healthcare facility. It took lots of hammer drilling and cable running, but we did it.

With regard to WAPs (wireless access points), you can physically connect them back to a switch which will provide you with wireless access interdependently with using the same network name "SSID." You may, however, need to login with a special key (or passphrase) to the network. This encrypts your transmissions between the devices and secures intrusion from outside the network. Without the cables back to the switch, the WAPs communicate between each other and create a "WDS" environment. RIOTTech went with the plenum Category 5e cable back to two managed CISCO switches.
