The precursor to Wi-Fi was invented in 1991 by NCR Corporation/AT&T (later Lucent & Agere Systems) in Nieuwegein, the Netherlands. It was initially intended for cashier systems; the first wireless products were brought on the market under the name WaveLAN with speeds of 1 Mbit/s to 2 Mbit/s. Vic Hayes, who held the chair of IEEE 802.11 for 10 years and has been named the 'father of Wi-Fi,' was involved in designing standards such as IEEE 802.11b, 802.11a and 802.11g.
Difference between wireless network and wireless sensor network?
The difference is a sensor network may be connected using wires or wirelessly, a wireless sensor network is always connected wirelessly.
The purpose of a wireless network sensor is to monitor environmental changes. It monitors things such as temperature, sound and pressure.
the wireless sensor network will penetrate exhilarated interfaces in the area of tight penetration ability
sensor which is used know about the environmental condition
A heterogeneous wireless sensor network(HWSN) is the network of sensors having wireless link with dissimilar communication range, sensing range or those sensors may be employed in numerous applications. In a distributed HWSN, different parts of HWSN may adapt different network configurations. The answer an be also include energy as basis for defining a network as heterogeneous , If wireless sensor network has 2 kinds of nodes , one type has x times more energy it can be called 2 level heterogeneous WSN and so on .
A Wireless sensor network, according to UbiBot, is a collection of devices that can exchange data gathered from a monitored field using wireless networks. The data is routed across numerous nodes and connects to other networks via a gateway, such as wireless Ethernet.
A wireless sensor network can use any suitable standard or non-standard protocol. Commonly used protocols include ZigBee (IEEE 802.15.4) and other members of the IEEE 802.15 protocol family.
Wireless sensor networks are capable of measuring certain aspects of a physical environment. For example, there are sensors available the measure temperature, pressure, and more.
