If you want to keep your wireless local area network access points safely out of harm's way, then the ceiling could be the place in which to do just that. Many modern buildings have this feature, which usually looks as if one ceiling tile has been replaced with one which has small antennas protruding from it. This is particularly common in places with suspended ceilings, as it is easy to place plenum enclosures for WLAN access points within them without it looking obtrusive or out of place in any way at all. A 'plenum' is a space which has been left for the purpose of the circulation of air within the construction of a building. Incorporating plenum enclosures for WLAN access points is something that will not interfere with any air conditioning units or air flow, and they can simply been seen as a new ceiling tile. The benefits it brings is keeping the access points off the floor, and by elevating them, it can put them above sources of interference, allowing for a stronger connection across the wireless local area network. There is also no danger of them bring disturbed, as is a risk with desktop hardware such as routers. The antennae themselves can be rotated and positioned upon the enclosure to give the best coverage possible. With plenum enclosures for WLAN access points, it should allow a network to perform very well across its intended environment. One obvious benefit of having a wireless local internet connection over a wired LAN, is that there are no issues of having cables trailing across the floor and desktops. It does make for a neater environment and can be more cost efficient than having cable connections installed whenever a new workstation is needed to be added to the network. With the wireless connection coming from the ceiling, all you will need is a wireless network card in your computer and you will be network ready wherever you are. Having the network connection distributed from the plenum enclosures for WLAN access points, lets network administrator build a secure network which can be spread across a large building area. It allows for great coverage over distances, as there should be limited interference, which is an issue with wireless connections. The necessity to maintain as much speed and efficiency within the workplace over a wireless local are network connection is clearly a paramount issue. The ceiling mounted access points help deliver this, while looking discreet, but still being easily accessible should any maintenance need doing.
