What is Wireless Communication ?
 Wireless communication is the transfer of information between
two or more points that are not connected by wires or cables.
 This is a broad term that incorporates all procedures and forms of
connecting and communicating between two or more devices
using a wireless signal through wireless communication
technologies and devices.
 Wireless operations permit services, such as long-range
communications, that are impossible or impractical to implement
with the use of wires.
 Wireless networking is used to meet many needs. Perhaps the
most common use is to connect laptop users who travel from
location to location. Another common use is for mobile networks
that connect via satellite. A wireless transmission method is a
logical choice to network a LAN segment that must frequently
change locations.

WL-GPS : GPS Application Trainer
 This kit system tracks up to twelve satellites simultaneously using
the antenna provided with the system.
 All GPS antennas operate on the line-of-sight principle; the
antenna must have line-of-sight visibility with at least three GPS
satellites for better analysis and understanding of GPS.
 Mounting the Trainer’s antenna outside a classroom window may
provide the necessary visibility. Students can perform various
experiments using this trainer.
 The Experimental Manual contains excellent discussion on several
GPS and GPS related topics, affording students a thorough
understanding of the Global Positioning System.
 Navigation concepts and GPS background are discussed.
Students learn about latitude and longitude and the measurement
accuracy of GPS hardware.
 The software analyzes the GPS data and provides a navigation
display. The software also has a ‘Trace Window’ that displays
analysis of received NMEA sentences.

What is GPS?
 The Global Positioning System (GPS) is a satellite-based
navigation system made up of a network of 24 satellites placed
into or bit by the U.S. Department of Defense.
 GPS was originally intended for military applications, but in the
1980s, the government made the system available for civilian
use. GPS works in any weather conditions, anywhere in the
world, 24 hours a day.
 There are no subscription fees or setup charges to use GPS.

WL-MHT : GSM Mobile Handset Trainer
A mobile phone is a phone that can make and receive telephone
calls over a radio link while moving around a wide geographic
area. It does so by connecting to a cellular network provided by
a mobile phone operator, allowing access to the public telephone
network. We have made a trainer kit to explain the technology of
working of Mobile phone i.e. Mobile Handset Trainer.

WL- Bluetooth : Bluetooth Trainer Kit
 Bluetooth is a proprietary open wireless technology standard for
exchanging data over short distances (using short wavelength
radio transmissions) from fixed and mobile devices, creating
personal area networks (PANs) with high levels of security.
 Bluetooth is a packet-based protocol with a master-slave
structure. One master may communicate with up to 7 slaves in a
piconet ; all devices share the master's clock.
 Bluetooth provides a secure way to connect and exchange
information between devices such as faxes, mobile phones,
telephones, laptops, personal computers, printers, Global
Positioning System (GPS) receivers, digital cameras, and video
game consoles.
 Bluetooth is a standard wire-replacement communications
protocol primarily designed for low power consumption, with a
short range (power-class-dependent, but effective ranges vary in
practice; see table below) based on low-cost transceiver
microchips in each device.

WL-ZIGBEE : ZigBee Trainer Kit
 ZIGBEE Alliance is the creation of a reliable, low-cost, lowpower, open global standard for low data rate wireless
solutions, while allowing multi-hop routing of data. The ZigBee
standard through mesh network capability and AES 128-bit
encryption provides support for self-healing and security.
Applications include
 Building automation for commercial monitoring and control of
facilities
 Remote control (RF4CE or RF for consumer electronics)
 Smart energy for home energy monitoring
 Health care for medical and fitness monitoring
 Home automation for control of smart homes
 Telecom Services and Network services related to large mesh
networks

A ZIGBEE network topology which typically includes three
types of devices or nodes:
 Coordinator: One coordinator exists in each network. It starts the
network and handles management functions as well as data
routing functions.
 Routers: In most cases, routers are also main-powered. They help
carry data across multi-hop ZigBee networks including a variable
number of routers and, in some cases, are without routers, thus,
transforming the network into a point-to-multipoint.
 End Devices: These are devices that are battery-powered due to
their low-power consumption. They sleep most of the time and
wake up regularly to collect and transmit data. Devices such as
sensors are configured as end devices. They are connected to the
network through the routers.

WL-RFID : RFID Trainer Kit
 Radio-frequency identification (RFID) is the use of an object
(typically referred to as an RFID tag) applied to or incorporated
into a product, animal, or person for the purpose of identification
and tracking using radio waves. Some tags can be read from
several meters away and beyond the line of sight of the reader.
 Radio-frequency identification comprises interrogators (also
known as readers), and tags (also known as labels).
 Most RFID tags contain at least two parts. One is an integrated
circuit for storing and processing information, modulating and
demodulating a radio-frequency (RF) signal, and other
specialized functions. The second is an antenna for receiving
and transmitting the signal.

WL-CDMA : CDMA Mobile Communication
 CDMA (Code-Division Multiple Access) refers to any of several
protocols used in so-called second-generation (2G) and thirdgeneration (3G) wireless communications. As the term implies,
CDMA is a form of multiplexing, which allows numerous signals to
occupy a single transmission channel, optimizing the use of
available bandwidth. The technology is used in ultra-high-frequency
(UHF) cellular telephone systems in the 800-MHz and 1.9-GHz
bands.
 CDMA employs analog-to-digital conversion (ADC) in combination
with spread spectrum technology. Audio input is first digitized into
binary elements. The frequency of the transmitted signal is then
made to vary according to a defined pattern (code), so it can be
intercepted only by a receiver whose frequency response is
programmed with the same code, so it follows exactly along with the
transmitter frequency. There are trillions of possible frequencysequencing codes, which enhances privacy and makes cloning
difficult. The CDMA channel is nominally 1.23 MHz wide.
