Abstract

A system is provided that includes a control panel having a wireless transceiver that operates under a 6LowPan/IPv6/IoT protocol, wherein 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, wherein at least some of the plurality of wireless devices select TDMA slots of the super frame under a carrier sense multiple access with collision avoidance (CSMA/CA) algorithm/mechanism and some other of the plurality of wireless devices select TDMA slots of the super frame under a WiFi protocol.

First claim

The invention claimed is:

1. A system comprising:
a control panel having a first wireless transceiver that operates under a IPv6 over Low Power Wireless Personal Area Network (WPAN)(6LowPan)/Internet Protocol version 6(IPv6)/Internet of Things(IoT) protocol, wherein the 6LowPan/IPv6/IoT protocol supports one or more of a 6LowPan protocol, an Institute of Electrical and Electronics Engineers(IEEE)802.15.4 protocol, and IEEE802.11 coordination;
a plurality of remotely located, wireless devices, wherein each of the plurality of remotely located, wireless devices has a respective second wireless transceiver that exchanges first messages with the control panel within a respective one of a plurality of time division multiple access (TDMA) slots on a radio frequency (RF) channel; and
a first processor within the control panel and a respective second processor within each of the plurality of remotely located, wireless devices that control transmission and reception of the first messages within the plurality of TDMA slots of a repeating super frame,
wherein at least some of the plurality of remotely located, wireless devices select the respective one of the plurality of TDMA slots of the repeating super frame under a carrier sense multiple access with collision avoidance (CSMA/CA) algorithm/mechanism and some other of the plurality of remotely located, wireless devices select the respective one of the plurality of TDMA slots of the repeating super frame under a WiFi protocol,
wherein a first set of the plurality of TDMA slots is reserved for remotely located, wireless devices of the plurality of remotely located, wireless devices operating under the 6LowPan/IPv6/IoT protocol,
wherein a second set of the plurality of TDMA slots is reserved for remotely located, wireless devices of the plurality of remotely located, wireless devices operating under the WiFi protocol, and
wherein the first wireless transceiver of the control panel transmits a beacon that identifies a temporal location of the first set of the plurality of TDMA slots to the at least some of the plurality of remotely located, wireless devices.

2. The system as in claim 1 wherein a third set of the plurality of TDMA slots is 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.

3. The system as in claim 1 wherein the at least some of the plurality of remotely located, wireless devices operate under the 6LowPan/IPv6/IoT protocol.

4. The system as in claim 3 wherein the beacon further comprises unicast, multicast, or broadcast messages simultaneously activating a respective audio indicator of each of the at least some of the plurality of remotely located, wireless devices.

5. The system as in claim 1 wherein the at least some of the plurality of remotely located, wireless devices comprise sensors.

6. The system as in claim 5 wherein the sensors comprise intrusion sensors.

7. The system as in claim 5 wherein the sensors comprise life safety sensors.

8. The system as in claim 5 wherein the control panel, the sensors, and audio alarm devices comprise a security system.

9. A system comprising:
a control panel;
a first wireless transceiver of the control panel;
a first processor of the control panel that exchanges messages with a plurality of remotely located, wireless devices through the first wireless transceiver within a repeating super frame, wherein the repeating super frame comprises a first portion that operates under IPv6 over Low Power Wireless Personal Area Network (WPAN)(6LowPan)/Internet Protocol version 6(IPv6)/Internet of Things(IoT) and Institute of Electrical and Electronics Engineers(IEEE)802.15.4 protocols and a second portion that operates under IEEE802.11 coordination;
a respective second wireless transceiver of each of the plurality of remotely located, wireless devices that exchanges the messages with the control panel within a respective one of a plurality of time division multiple access (TDMA) slots of the repeating super frame on a radio frequency (RF) channel; and
a respective second processor within each of the plurality of remotely located, wireless devices that controls transmission and reception of the messages within the plurality of TDMA slots of the repeating super frame,
wherein at least some of the plurality of remotely located, wireless devices select the respective one of the plurality of TDMA slots of the repeating super frame under a carrier sense multiple access with collision avoidance (CSMA/CA) algorithm/mechanism and some other of the plurality of wireless devices select the respective one of the plurality of TDMA slots of the repeating super frame under a WiFi protocol,
wherein a first set of the plurality of TDMA slots is reserved for remotely located, wireless devices of the plurality of remotely located, wireless devices operating under the 6LowPan/IPv6/IoT protocol,
wherein a second set of the plurality of TDMA slots is reserved for remotely located, wireless devices of the plurality of remotely located, wireless devices operating under the WiFi protocol, and
wherein the first wireless transceiver of the control panel transmits a beacon that identifies a temporal location of the first set of the plurality of TDMA slots to the at least some of the plurality of remotely located, wireless devices.
