Question

A nurse is having problems with the patient monitors connecting to the medical device wireless network in a shared department space. The nurse can detect several other wireless network signals. All of the wireless networks have different SSIDs but several are using the same encryption type. What should be configured on the patient monitoring wireless network to improve connectivity to the medical device wireless network?

Answer 1

Answer:

The following needs to be done to improve the connectivity:

1. Proper sheilding of the patient monitoring wireless network and devices from EMI interferences.

2. Used of Enhanced WLAN security technology like WPA/WPA2( wireless protected access). It a enhanced WEP( wired equivalent privacy) which enforces TKIP( temporal key integrity protocol) , it uses temporary encryption keys which are changed automatically at regular time intervals. Thus greatly improving wireless LAN connectivity, because only receivers having the correct key can decrypt the information. And since the keys keep updating/changing it is very rare that a security breach happens.

3. Implement the MACA (multiple access with collision avoidance) algorithm to solve the collussions happening due the common ''hidden node problem ' prevelent in WLANs.
