Bluetooth is a specification (IEEE 802.15.1) that uses low-power radio communications to connect phones, computers and other network devices over short distances without wires. The name Bluetooth is borrowed from Harald Bluetooth, King of Denmark that lived more than a 1,000 years ago.
One of the oldest wireless protocols is still widely available, Bluetooth was created in 1990 to synchronize data between your phone and other battery platforms. Bluetooth requires less power to operate than Wi-Fi and most other wireless protocols. In turn, the Bluetooth connection only works over relatively short distances, often 30 feet (10 m) or less, and supports relatively low data rate, typically 1-2 Mbps. Wi-Fi, Bluetooth is switched on some newer equipment, but many phones today still support both protocols.
60 GHz Protocols - WirelessHD and WiGig
One of the most popular activities to do on computer networks is the streaming of video data, and there are quite many wireless protocols that run on 60 Gigahertz (GHz) frequencies that have been built to support this in a better way and also other usages which need huge amounts of network bandwidth. There are two different industry standards and they are called WirelessHD and WiGig. They were made in the 2000s both using 60 GHz technology in order to support high-bandwidth wireless connections: WirelessHD supports between 10 and 28 Gbps and WiGig offers between 1 and 7 Gbps of bandwidth.
Although the main video stream can be done via Wi-Fi network, the best quality high definition video streams require higher data rates offered by these protocols. Because there are very high signaling frequencies when it come to WirelessHD and WiGig compared to Wi-Fi (they are 60 GHz compared to 2.4 or 5 GHz) they greatly lessen connection range, usually less than Bluetooth, and mostly to within a single room (because 60 GHz signals can't penetrate walls very well).
Wireless Home Automation protocols - Z - Wave and Zigbee
Various network protocols are designed to support home automation systems that allow remote control of lights, appliances, and consumer gadgets. Two prominent protocols for wireless home automation are Z-Wave and Zigbee. In order to achieve ultra-low power consumption required in the environment of home automation, these protocols and their associated hardware support only low data rates like 0.25 Mbps for ZigBee and only about 0.01 Mbps for Z-Wave. Although these data rates are clearly unsuitable for general purpose networking, these technologies work on consumer interface devices that are simple and limited when it comes to communication requirements.
