Abstract

A monitoring system includes one or more units that are adapted monitor the radio frequency conditions of a facility or portion of the facility. The units include a packet sniffer and/or an RF spectrum analyzer. Sniffed packets and spectrum data are recorded and made available for analysis and display, either locally on the units or at one or more remote locations. The locations of the units are also gathered, thereby enabling correlation of the sniffed packets and/or RF spectrum data with locations within the facility. Real time RF conditions can thereby be gathered and used to improve the wireless communications within the facility and/or to ensure the wireless communication infrastructure of the facility is operating satisfactorily. The units may be person support apparatuses, such as beds, chairs, stretchers, cots, or the like.

Claims16

Dependent claims

A system comprising:

a server communicatively coupled to a local area network;
a plurality of person support apparatuses, each of the person support apparatuses comprising:
(a) a support surfaced configured to support a patient thereon;
(b) a sensor configured to detect a parameter of the person support apparatus;
(c) a radio frequency (RF) spectrum analyzer configured to gather RF spectrum data for first and second communication channels;
(d) a transceiver configured to wirelessly transmit sensor data from the sensor to the server via an access point of the local area network, the transceiver communicating with the access point over the first communication channel, the transceiver further configured to wirelessly transmit the RF spectrum data for the second communication channel to the server via the access point of the local area network using the first communication channel;
and
a user interface communicatively coupled to the server and configured to receive the RF spectrum data from the RF spectrum analyzers.
