Who WiFi, bluetooth, Zigbee wireless communication technology is more suitable for Internet domain?

in order to better serve end users, utilities and urban council began to extend intelligent metering system, in order to solve the problem of real-time data continues to grow. Utilities by smart meters, can be more frequent and more effective to check the customer's energy consumption information, at the same time also can rapid identification, isolation, and solve the problems such as a power failure. Consumers can get information by interconnect. Indoor network equipment can real-time reports its state and energy consumption, and also can response information from the utility company. Using intelligent energy and smart home system, consumers will be more convenient and efficient, for example, at the time of the lowest electricity control activate the dishwasher, or timely remind users need to add detergent.

wireless network technology core features and capabilities

Wi - Fi is based on 2. 4 GHZ spectrum communication technology, the rapid transmission of large amounts of data between two nodes, is widely used in many iot application cases, the most common of which are as the link from the gateway to connect to the Internet router. However, it is

a high speed and distance has also been used for the main wireless link.

Bluetooth is another 2. 4 GHZ technology, its for portable devices, mainly as a point-to-point solutions that support only a few nodes.

Zig Bee with Bluetooth and Wi Fi share the same radio spectrum, but is only used to meet the specific requirements of the low power wireless sensor nodes.

Zig Bee: wireless mesh network optimization solutions

ZigBee based on global standards, is an open wireless mesh network technology. Different from the traditional network architecture, such as star and point to point, mesh network nodes using the lowest cost for all position to provide reliable coverage within buildings ( See below in the network topology option comparison) 。 ZigBee USES dynamic routing protocols, autonomous, based on AODV ( 特别的, 民主党和距离向量) The routing technology. In AODV, when a node needs to connect, he will broadcast a request message routing, the other nodes in the routing table lookup, if you have arrived at the destination node routing, then feedback to the source node, the source node to pick a reliable and hop count minimum route, and store the information to the local routing table for future needs, if a routing link fails, nodes to select another simple alternative routing lines. If the shortest route between the source and destination is blocked by walls or multipath interference, ZigBee can find a longer but available adaptive routing lines.

we can quickly to compare these three technology mentioned in the article. Everything at the same time, the Internet market, industry, transportation, agriculture, water conservancy and medical all walks of life, such as application requirements are different. Therefore, for the Internet of things a long tail in the market, we can be sure that any standard is not dominant. However, we can easily find for specific application one of the most appropriate technology to counterpart.
