Various methods of measuring based on wireless technologies have been used for a long time in industry, in applications where communication over long distances is a must and where the costs for installing wires is much higher than the one of transmitting data over radio frequencies. Drill stems, gas infrastructures, pumping stations, agriculture projects, these are just a few of the examples where a wireless radio communication is successfully used. The thing that makes this method even more interesting today is the convergence of technologies pf powerful microprocessors with reduced consumption, with the technologies of huge radio devices that also have a reduces power consumption.
Minimizing these types of components makes it possible to build today a wireless network which can work on batteries for years, even if it is not under strict surveillance. The wireless sensor network is a measuring instrument that is virtually manages, which means it is handled with the help of a computer.
ZigBee represents the definition of a technical specification utilized in digital radio protocols of communications, of small power, based of the wireless IEE 802.15.4 standard for personal wireless networks. The ZigBee 1.0 version has been accepted and standardized on the 14th of December 2004.
Operating on the radio frequencies of 868 Mhz in Europe, 915 Mhz in USA and 2.4Ghz in most countries, a ZigBee radio circuit that has been produces in a very small series in the USA used to cost around 1 dollar and the price of a small controller for this network is smaller than 3 dollars. Using a technology that is much simpler and much cheaper than the one in regular wireless networks, with software dimensions that are between 2% and 10% out of the ones used for a typical Bluetooth hotspot, the ZigBee networks are designed for applications with low consumptions of power (changing batteries can be done in some cases once every two years) and that do not need high transfer rates.
A zigbee wireless network can be used in a wide amount of domains, from industrial controls, to networks with integrated sensors, Getting medical data and in anti-fire and anti-theft systems or even in automatic devices that permit the existence of intelligent buildings and homes.
In the end, it is clear that these networks have been around for a while and we are probably making used of the wireless technology in many other ways, more than we dream of. Its not only the mobile phones, laptops and entertainment devices the ones that need wireless to function.
There are so many other more vital thing that are using the wireless technology that we cant even imagine, and the fact that the wireless network used by those devices are even more evolved and a lot more secure than the ones we use in our everyday browsing makes us wonder how come we have never though about their existence.
