On a small scale technologies such as Zigbee and Bluetooth facilitate communication between devices in close range. Known as Personal Area Network Devices, these are presently used in devices such as smart phones and PDAs. As of now Bluetooth is the preferred technology in these applications, however Zigbee is cheaper to produce and easier to use. It has the ability to self organize in a mesh network and can run for years at a time on a single battery. Already Zigbee has been used in alarm and home automation systems. It is capable of transferring data from node to node rather than from node to server to node, creating faster and simpler communication.
LAN
On a larger scale, Ultra-Wide Band wireless communication allows users to quickly transfer large amounts of information at close range. This type of network is ideal for working in collaboration with other kinds of networks.
The more versatile networks facilitate communication that is outside the range of the previous networks. The most popular system in this range is WiFi. Since its inception, WiFi has been the most popular choice for Wireless Local Area Networks. It offers users broadband speed, wirelessly, within a range of 150 ft. It has enjoyed a widespread acceptance in home and business settings. However the short range of its signal makes it impractical for creating wireless mesh networks or bringing Internet into remote locations.
MAN
WiMax offers a larger range and higher speeds than Wi-Fi. Its main use is in creating Metropolitan Area Networks. With projected ranges of 50 km and proven ranges of 8 km, WiMax allows for powerful networks within cities and in remote areas. Major US cities have already installed WiMax systems, which can facilitate wireless Internet and mobile device connectivity. The huge bandwidth of WiMax is equivalent to more than 60 T1 lines. It also is capable of transmitting with a line of sight, which is ideal in urban environments.
Both WiMax and WiFi provide broadband connection to users, however they are only usable at speeds under 100 km/h. Mobile users would be unable to maintain a connection using these networks. MobileFi provides users low latency connection at speeds of up to 250km/h. Although it is better suited for quickly moving mobile connections it only has half the bandwidth of WiMax.
Mesh Networks are another step in realizing an Internet of Things. Currently most WiFi and WiMax networks are centralized and require a lot of infrastructure to scale beyond small networks. Mesh Networks offer a decentralized network that uses the power of each signal or node to create a web of communication that is more efficient at distributing signals. Mesh networks also allow for an even division of bandwidth between users. Mesh networking also facilitates long distance connectivity in weak signal areas through transmission from device to device until it makes a connection.
