Bluetooth technology is based on Ad-hoc technology also known as Ad-hoc Pico nets , which is a local area network with a very limited coverage. The distances involved may be short (a few meters as in television remote control) or long (thousands or millions of kilometers for radio communications). A wireless network is also named a WiFi network. INTRODUCTION Wireless communication is the transfer of information over a distance without the use of enhanced electrical conductors or "wires”. ! Wireless LANs Behrouz A.

View Notes - advance ch14 wireless.ppt from ECE ECL 402 at Visvesvaraya National Institute of Technology. WiFi @ 1+ Gbps standards being defined ! A wireless router is one kind of hardware device which is commonly used in homes. by mobile network participants in Automatic Guided Vehicles (AGV) or in crane applications. How does WiFi work? The first and oldest wireless technology used in medical application is wireless local area network (WLAN). Interference 4. This device is mainly used by the providers of internet service to connect their internet cable. Fading and shadowing 3. The standards of WLAN was first introduced in 1997, namely IEEE 802.11. How do mobile phones work? What is Wifi? Sometimes, it is also called a WLAN device (wireless local area network). Through wireless communication! It is the heart of the wireless network. Doppler shift 3.1 Path loss Path loss can be expressed as the ratio of power of transmitted signal to the power of the same signal received by the receiver on a given path. Not only the hardware, but also the software of the network components must meet special requirements for use in the industry.
