| This report addresses a group of telecommunications standards related to supporting short distance wireless communications and providing a very long battery life. Such communication is a requirement for various applications, including military and commercial:
-UGS networks. These networks contain numerous ground sensors, often deployed in the mesh topology, and supported by radios for the time of their functioning. These sensors collect environmental and other information and deliver to the main node.
-Public Safety Communications
-Home Environment.
The report analyses radio technologies used to support these applications. It emphasizes the importance of these radios low power consumption - they have to work unattended for months and even years.
We identified:
-UWB
-ZigBee
-Bluetooth
-Wibree
-NFC.
The report provides a detailed marketing and technical analysis for each technology in this group. The goal was:
-To identify major strong and weak sides for each technology
-To analyze their major features
-To analyze their major applications
-To analyze the industries defining their major players.
The most developed technology is Bluetooth with a huge market; it is lately consumed Wibree, which was originally designed to cover BT applications that require extremely low consumption.
ZigBee, which can only support lower speeds of transmission (than BT), seems already the established technology for mesh topologies and industrial automation, can also support a radio node self-efficiency at least for months.
In our opinion, UWB is the most promising and effective technique in the group of discussed radios. It supports:
-NLOS communications
-Covered communications
-Speeds from several Kb/s to Gb/sec
-Extremely low power consumption allowing low-speed communication node to be self-efficient for years
-Combination of effective communications with radar that can detect objects location with extreme accuracy.
Unfortunately, at the present time, UWB still faces standardization uncertainty; we believe (and ours believe is supported by recent developments in the U.S. and oversees) that UWB soon overcome its problems.
Finally, NFC seems also has a bright future for specific applications that require to start communications at short distances (fracture of meter).
The report is aimed to a wide audience of technical and management staff that works in the design and implementation of related networks and applications.
