9.6.1 NUREP Wireless Repeater
The wireless repeater (NUREP) is a surface (wall) mounted teleCARE IP wireless
infrastructure building-block. Wireless repeaters receive the signals from the wireless
modules from residents and all the wireless modules in the resident room. Wireless
repeaters also retransmit these signals to the central equipment (wireless gateway), via
other wireless repeaters.
Wireless repeaters are dual RF transceivers. One RF transceiver (916 to 921 MHz) is used for
the local traffic, events from the resident pendant, wrist transceiver or the fixed wireless
modules in the room. A 2.4 GHz IEEE 802.15.4 transceiver (supporting channels 15, 16, 20,
21 and 25) is used for transmitting the events to the other wireless repeaters, thereby
creating a wireless backbone that is capable of handling high traffic.
Wireless repeaters are used to create a wireless infrastructure that covers the whole site.
Wireless repeaters are mainly used indoors, however when using a suitable weatherproof
enclosure that meets local electrical code, outdoor use is possible.
Repeaters are supervised by the central equipment. Repeaters deliver a complete 2-way
radio infrastructure, from the wireless device at the resident or room, to the central
equipment.
Wireless repeaters are DC-powered via a 5 VDC Class II power adapter that comes included
with the repeater. Wireless repeaters also have a battery backup source providing power for
approximately three days, in case of mains power failure.
