Smart thermostat
Smart thermostats are thermostats that can be used with home automation and are responsible for controlling a home's heating and/or air conditioning. They perform similar functions as a Programmable thermostat as they allow the user to control the temperature of their home throughout the day using a schedule, but also contain additional features, such as sensors and WiFi connectivity, that improve upon the issues with programmable thermostats,
HomeRF
Initially called Shared Wireless Access Protocol (SWAP) and later just HomeRF, this open specification allowed PCs, peripherals, cordless phones and other consumer devices to share and communicate voice and data in and around the home without the complication and expense of running new wires. HomeRF combined several wireless technologies in the 2.4 GHz ISM band, including IEEE 802.11 FH (the frequency-hopping version of wireless data networking) and DECT (the most prevalent digital cordless telephony standard in the world) to meet the unique home networking requirements for security, quality of service (QoS) and interference immunity—issues that still plagued Wi-Fi (802.11b and g).
