摘要： An apparatus includes a tablet computing device and a radio module physically fastened to the tablet computing device. The tablet computing device has a display and is configured to establish WiFi and BLUETOOTH Low Energy (BLE) communication links with other devices. The radio module is configured to establish ISA100 and WirelessHART communication links with field devices of a process control and automation system. The tablet computing device and the radio module are configured to communicate with each other using a BLE communication link. The apparatus is configured to selectably operate in multiple modes comprising a gateway mode, a router mode, a sniffer mode, and a discovery mode.

摘要： A hybrid slotted time division multiple access (TDMA) and carrier sense multiple access (CSMA) based networks that optimize radio frequency (RF) based network resources, RF infrastructure, and improve network performance in a building which may include time critical sensors, such as smoke sensors, and non-critical sensors. The present system may classify critical sensors as guaranteed sensors which get TDMA slots assigned by a network manager. The non-critical sensors may operate in non-guaranteed CSMA slots but within a predefined latency interval. The present system may provide for both types of sensors to co-exist in tandem within the same wireless network.
