Using wake-up receivers for soft hand-off in wireless communications
First Claim
Patent Images
1. An apparatus configured to facilitate a soft hand-off in wireless communications, comprising:
- (a) a plurality of low power radio systems, each including;
(i) a two-way wireless communication device, and(ii) a wake-up receiver; and
(b) a controller, physically connected to each wake-up receiver to receive signals therefrom and further connected to each two-way wireless communications device to effect two-way communication therethrough, wherein the controller is adapted to select one of the plurality of two-way wireless communication devices for external two-way wireless communications, the selection being made on the basis of an electronic signal received from at least one of the plurality of wake-up receivers, and the selection being made based on a determination, informed by monitoring, that one of the low power radio systems is more reliable than another of the low power radio systems;
(c) wherein the controller is adapted to wirelessly transmit data via the selected two-way wireless communications device;
(d) wherein one of the wake-up receivers is adapted to transmit an electronic signal only upon receiving a wake-up signal that includes a class designation corresponding to the apparatus.

Abstract
Multiple standards based radio (“SBR”) devices, each having a high-gain directional antenna, are utilized in a remote sensor interface (“RSI”) unit to optimize detection and reception by the RSI of radio signals from gateway controllers, hopping radios, and other wireless devices.

5. A method of facilitating a soft hand-off in wireless communications at a wireless component, the wireless component including a controller and first and second low power radio systems, each low power radio system including a wake-up receiver, and the controller being physically connected to each wake-up receiver to receive signals therefrom, the method comprising:
-
(a) electronically communicating, via a two-way wireless communication device of the first low power radio system, data; (b) receiving, at the wake-up receiver of the second low power radio system, a wake-up signal that includes a class designation corresponding to the wireless component; (c) in response to receiving a wake-up signal that includes the class designation, monitoring parameters associated with the second low power-radio system; (d) determining, based on said monitoring, that the second low power radio system is more reliable than the first low power radio system; and (e) activating, based on said determining step, a two-way wireless communication device of the second low power radio system and deactivating the two-way wireless communication device of the first low power radio system; (f) thereafter, electronically communicating, via the two-way wireless communication device of the second low power radio system, data. - View Dependent Claims (6, 7, 8, 9)

10. A method of facilitating a soft hand-off in wireless communications at a wireless component, the wireless component including a controller and first and second low power radio systems, the method comprising:
-
(a) receiving, at a wake-up receiver of the first low power radio system, a wake-up signal that includes a class designation corresponding to the wireless component; (b) in response to receiving a wake-up signal that includes the class designation at the wake-up receiver of the first low power radio system, monitoring parameters associated with the first low power radio system; (c) receiving, at a wake-up receiver of the second low power radio system, a wake-up signal; (d) in response to said step of receiving a wake-up signal at the wake-up receiver of the second low power radio system, monitoring parameters associated with the second low power radio system; (e) determining, based on said monitoring, that the first and second low power radio systems are equivalently reliable; and (f) arbitrarily selecting either the first low power radio system or the second low power radio system; (g) based on said selecting step, activating a two-way wireless communication device of the arbitrarily selected low power radio system; (h) thereafter, electronically communicating, via the activated two-way wireless communication device of the arbitrarily selected low power radio system, data; (i) wherein the controller is physically connected to each wake-up receiver to receive signals therefrom. - View Dependent Claims (11, 12, 13, 14)
