Site Survey Important for Wireless Systems


Thursday September 30th, 2004


Wireless networking is alluring on so many levels. It can boost productivity by offering remote access, and support flexible connectivity at a fraction of the cost of traditional wired networks. And allows surfing the internet from an room in your house or business. However care should be taken when considering or installing Wireless Local Area Networks (WLAN’s). Otherwise, one could fall victim to some of the most common mistakes made with WLANs.

 During the planning stages of a wireless installation, many people underestimate the importance of a site survey. Site surveys involve using software to measure the radio frequency signals at various points throughout buildings to determine the best locations to place access points while noting possible sources of interference to the signal, such as other WLAN’s, cordless phones, and microwave ovens.

Another consideration is security. No wireless device or network can ever be completely secure; however, there are precautions that add to the overall safety of using WLAN’s:

 


  • ·     Change factory settings in the routers. Hackers know the common default passwords and other information that makes intrusion easy if they're not changed.
     

  • ·     Enable the router's session timeout feature so that if no data passes through it after a set period of time, it shuts down.


Set routers to the lowest feasible power, so they keep the network devices connected without opening the door wider than necessary.  When deciding to whether to install a WLAN, consider using the services of qualified networking professionals. At PC on Call, our engineers have the experience and training to quickly and effectively deploy WLAN’s that range from a single laptop with one access point to complete cellular networks that allows for roaming from building to building in a large campus.
