Abstract

A system including a control panel having a wireless transceiver that operates under a 6LowPan/IPv6/IoT or equivalent protocol where the 6LowPan/IPv6/IoT protocol supports one or more of a 6LowPan protocol, an IEEE802.15.4 protocol and IEEE802.11 coordination, a plurality of remotely located, wireless devices each having a wireless transceiver that exchanges messages with the control panel within a time division multiple access (TDMA) slot on a radio frequency (RF) channel and a respective processor within the control panel and each of the plurality of wireless devices that controls transmission and reception of messages within TDMA slots of a repeating super frame where at least some of the plurality of wireless devices select TDMA slots within the super frame under a carrier sense multiple access with collision avoidance (CSMA/CA) algorithm/mechanism and some other of the plurality of devices select slots of the super frame under a WiFi protocol.

First claim

1 . A system comprising:
a control panel having a wireless transceiver that operates under a 6LowPan/IPv6/IoT or equivalent protocol where the 6LowPan/IPv6/IoT protocol supports one or more of a 6LowPan protocol, an IEEE802.15.4 protocol and IEEE802.11 coordination; a plurality of remotely located, wireless devices each having a wireless transceiver that exchanges messages with the control panel within a time division multiple access (TDMA) slot on a radio frequency (RF) channel; and a respective processor within the control panel and each of the plurality of wireless devices that controls transmission and reception of messages within TDMA slots of a repeating super frame where at least some of the plurality of wireless devices select TDMA slots within the super frame under a carrier sense multiple access with collision avoidance (CSMA/CA) algorithm/mechanism and some other of the plurality of devices select slots of the super frame under a WiFi protocol.

2 . The system as in claim 1 further comprising a first plurality of slots reserved for remotely located wireless devices of the plurality of remotely located wireless devices operating under the 6LowPan/IPv6/Iot protocol.

3 . The system as in claim 2 further comprising a second plurality of slots that are different than the first plurality of slots, the second plurality of slots are reserved for remotely located wireless devices of the plurality of remotely located wireless devices operating under the WiFi protocol.

4 . The system as in claim 3 further comprising a third plurality of slots that are different than the first and second pluralities of slots, the third plurality of slots are reserved for remotely located wireless devices of the plurality of remotely located wireless devices operating under the 6LowPan/IPv6/Iot protocol operating under the CSMA/CA algorithm/mechanism.

5 . The system as in claim 2 further comprising a transceiver that transmits a beacon that identifies a temporal location of the first plurality of slot to at least some of the plurality of remotely located wireless devices where the at least some devices operate under the 6LowPan/IPv6/Iot protocol.

6 . The system as in claim 1 wherein the beacon further comprises a unicast, multicast, or broadcast messages simultaneously activating an audio indicator of the at least some devices.

7 . The system as in claim 1 wherein the at least some devices further comprise sensors.

8 . The system as in claim 7 wherein the sensors further comprise intrusion sensors.

9 . The system as in claim 7 wherein the sensors further comprise life safety sensors.

10 . The system as in claim 7 wherein the, control panel, the sensors and audio alarm devices further comprise a security system.

11 . A system comprising:
a control panel; a wireless transceiver of the control panel; and a processor of the control panel that exchanges a plurality of messages through the wireless transceiver within a repeating super frame, the repeating super frame further comprising a first portion that operates under 6LowPan/IPv6/IoT and IEEE802.15.4 protocols and a second portion that operates under IEEE802.11 coordination.

12 . The system as in claim 11 further comprising a plurality of remotely located, wireless devices each having a wireless transceiver that exchanges messages with the control panel within a time division multiple access (TDMA) slot on a radio frequency (RF) channel.

13 . The system as in claim 11 further comprising a respective processor within the control panel and each of the plurality of wireless devices that controls transmission and reception of messages within TDMA slots of a repeating super frame where at least some of the plurality of wireless devices select TDMA slots within the super frame under a carrier sense multiple access with collision avoidance (CSMA/CA) algorithm/mechanism and some other of the plurality of devices select slots of the super frame under a WiFi protocol.

14 . The system as in claim 11 wherein the first portion further comprises at least some slots that operate under a CSMA protocol.

15 . The system as in claim 11 wherein the second portion further comprises at least one slot that operates under a WiFi protocol.

16 . The system as in claim 14 further comprising a processor that transmits a beacon within one of the first and second portions.

17 . The system as in claim 11 wherein the first portion further comprises packets transmitted under a IEEE802.15.4 protocol.

18 . A system comprising:
a control panel; a wireless transceiver of the control panel; a processor of the control panel that exchanges a plurality of messages through the wireless transceiver within a repeating super frame, the repeating super frame further comprising a first portion that operates under 6LowPan/IPv6/IoT and IEEE802.15.4 protocols and a second portion that operates under IEEE802.11 coordination; a plurality of remotely located, wireless devices each having a wireless transceiver that exchanges messages with the control panel within a time division multiple access (TDMA) slot of the repeating super frame on a radio frequency (RF) channel; and a respective processor within the control panel and each of the plurality of wireless devices that controls transmission and reception of messages within TDMA slots of a repeating super frame where at least some of the plurality of wireless devices select TDMA slots within the super frame under a carrier sense multiple access with collision avoidance (CSMA/CA) algorithm/mechanism and some other of the plurality of devices select slots of the super frame under a WiFi protocol.

19 . The system as in claim 18 further comprising a first plurality of slots reserved for remotely located wireless devices of the plurality of remotely located wireless devices operating under the 6LowPan/IPv6/Iot protocol.

20 . The system as in claim 19 further comprising a second plurality of slots that are different than the first plurality of slots, the second plurality of slots are reserved for remotely located wireless devices of the plurality of remotely located wireless devices operating under the WiFi protocol.
