Wireless communication

• In terms of telecommunication, wireless communications are be used to transfer information over.

Short distances(such as TV Remote control)

Long distances (such as radio communications)

Through wireless

The main aim of wireless technology is to communicate with any thing from any place at anytime .

here thing refers to the information (eg messages, multimedia or voice conversations) on any electronic devices, in order to communicate between two devices.

examples of wireless telecommunications are cellular mobile phones, PDA, satellite television, and cordless telephones.

Types of wireless communication networks

LAN

Provides data rates of 1 to 20 Mbps . Eg wi-fi, fixed wireless data

WANCovers large geographical areas, WAN systems base station, wireless bridging relays. connect public internet access system.

MAN Interconnects several LANS

.

PAN interconnect devices within a relatively small areasEg bluetooth, zigbee, infrared.

Mobile devices networks The GSM network the switching system, the base station system, the operation and support system.

personal communication service(PCS) is a radio band.

Digital Advanced Mobile Phone Service DAMPS.

Cellular mobile phones generations

1G mobile phone Firstly introduced at NTT in 1979. Analogue circuit-switched technology, with FDMA. Works mainly in the (800-900) MHz frequency bands they relied on a network of distributed transceivers to communicate with the mobile phones low traffic capacity, unreliable handover, poor voice quality, and poor security.

2G mobile phone introduced in late 1980’s and early 1990’s with GSM standard. provided with pure digital technology 2G introduced data services for mobile, starting with SMS text messages & multimedia. data rates were only 9.6 kbps.

2G (multiplexing)

TDMA CDMA

PDC, IDEN, IS 136 IS- 95, CDMA one

3G mobile phone

Japan was the first country to introduce a 3G system. support much higher data transmission rates (144kbps- 384 kbps)and offer increased capacity of voice calls. uses packet-switching technology. TV streaming, multimedia, videoconferencing, Web browsing, e-mail, paging, fax, and navigational maps.

4G mobile phones

this technology can have a high uplink rate up to 200Mbps. 4G will bring almost perfect real world wireless or called “WWWW: World Wide Wireless Web A 4G system is expected to provide a secure all-IP based mobile broadband solution to smart phones, laptop computer wireless modems. Facilities such as ultra-broadband Internet access, IP telephony, gaming services, and streamed multimedia may be provided to users.

4G is a research item for next-generation wide-area cellular radio, where you have 1G, 2G, 3G and then 4G [and 5G]

4G is a conceptual framework and a discussion point to address future needs of a high speed wireless network

It offer both cellular and broadband multimedia services everywhere

released on June 2010 - present.

Global 4G wireless system

5G mobile phone

5G is a completed wireless communication with almost no limitation; somehow people called it REAL wireless world

5G wireless system is only theory and not real.

The Router and switch technology used in 5G network providing high connectivity.

5G Technologies have an extraordinary capability to support Software and Consultancy

The 5G technology distributes internet access to nodes within the building and can be deployed with union of wired or wireless network connections.

5G features

• 5G technology offer high resolution and bi-directional large bandwidth shaping.

• 5G technology also providing subscriber supervision tools for fast action.

• 5G technology is providing large broadcasting of data in Gigabit which supporting almost 65,000 connections

• The 5G technology is provides 25 Mbps connectivity speed and support virtual private network.

• 5G technology offer transporter class gateway with unparalleled consistency.

conclusion

• Wireless systems becoming an important infrastructure in our society. A virtual global system is a good solution that can efficiently connect many dedicated wireless systems including 2G to 4G cellular systems, wireless LAN, broadcasting systems, etc.

Any queries..?
