INTRODUCTION OF WIRELESS NETWORK

Wireless is a term used to describe telecommunications in which electromagnetic waves (rather than some form of wire) carry the signal over part or all of the communication path.

The word wireless is dictionary defined as "having no wires". In networking terminology, wireless is the term used to describe any computer network where there is no physical wired connection between sender and receiver, but rather the network is connected by radio waves and/or microwaves to maintain communications. Wireless networking utilizes specific equipment such as NICs, APs and routers in place of wires (copper or optical fiber) for connectivity.

1G TECHNOLOGY-1G refers to the first generation of wireless

telephone technology(mobile telecommunications) which was first introduced in 1980s and completed in early 1990s.

It's Speed was up to 2.4kbps.It allows the voice calls in 1 country.1G network use Analog Signal.AMPS(Advanced  Mobile Phone System) was

first launched in USA in 1G mobile systems.

LIMITATIONS- Battery life is poor. Poor voice quality. No Security system. Phones are large in size. Capacity is limited. Poor Handoff Reliability

2G TECHNOLOGY-

2G technology refers to the 2nd generation which is based on GSM.It was launched in Finland by Radiolinja in the year 1991.2G network use digital signals.It’s data speed was up to 64kbps.

FEATURES INCLUDES-

It enables services such as text messages, picture messages and MMS(Multi Media Message).

It provides better quality and capacity.

2G requires strong digital signals to help mobile phones work. If there is no network coverage in any specific area , digital signals would weak.

These systems are unable to handle complex data such as Videos.

LIMITATIONS-

WIRELESS MODELS OF 1G AND 2G

1G WIRELESS SYSTEMS 2G WIRELESS SYSTEMS

2G TECHNOLOGY-

2.5G is a technology which is between 2nd generation(2G) and 3rd generation(3G) in the world of mobiles.

It bridged 2G to 3G wireless technology.

FEATURES INCLUDES- Conference Call, Speed Dialing, Hands Free, Loudspeaker,

Call Diver. Navigation Technology with Nokia maps 2.0. Emails can be Sent/Receive. Speed up to 200kbps. Battery life is good (Talk Time-14 hrs. and Standby Time-528hrs). Web Browsing(users can use internet).

3G TECHNOLOGY-

3G technology refer to third generation which was introduced in year 2000s.

3G Technology is designed for multimedia communication. It provides services like higher data transfer rates.

Speed- While in 3G technology the downloading and uploading speeds are up to 21 Mbps and 5.7 Mbps respectively.

These phones are also called as Smart Phones.

FEATURES INCLUDES-

3G technology offers a high level of security when communicating with other devices.

3G network allows video calling, live streaming, mobile internet access, IPTV, etc. on the mobile phones.

3G technology the downloading and uploading speeds are up to 21 Mbps and 5.7 Mbps respectively.

In 3G Network Videos/Images can be download easily.

Provide faster communication. Large storage capacity. Application can be install in phones.

LIMITATIONS-

3G Phones are much costlier. 3G network will be excessively high if they

make use of the various applications of 3G. A drawback of 3G is that it is simply not

available in certain regions. 3G Phones are large in size.

4G TECHNOLOGY-

The official launch of 4G is due in early 2015. On 12 March 2015, ANRT have reviewed all applications, and accorded 4G licenses to the main operators.

Speed up to 100Mbps-1Gbps. Fourth generation (4G) technology will offer many

advancement to the wireless market, including downlink data rates well over 100 Mbps.

One of the basic term used to describe 4G is MAGIC. MAGIC:

M- Mobile MultimediaA- Anytime AnywhereG- Global Mobility SupportI- Integrated Wireless SolutionC- Customized Personal ServicesAlso known as Mobile Broadband Everywhere.

Provide any type of services at any time as per our requirement.

Higher security functions.

FEATURES INCLUDES- Large storage capacity. Security is More. High Speed. Provide faster communication.

LIMITATIONS- Battery drain very fast. Hard to implement. Need complicated hardware. Expensive equipment required to

implement next generation network.

COMPARISON BETWEEN 3G AND 4G

The basic difference between 3G and 4G is in data transfer and signal quality.

TECHNOLOGY 3G 4G

DATA TRANSFER RATE 3.1MB/Sec 100MB/Sec

INTERNET SERVICES BROADBAND ULTRA BROADBAND

MOBILE - TV RESOLUTION LOW HIGH

BANDWIDTH 5-20MHz 100MHz

FREQUENCY 1.6-2GHz 2-8GHz

DOWNLOAD AND UPLOAD 5.8Mbps 14Mbps

WIRLESS MODELS OF 3G AND 4G-

5G TECHNOLOGY-

5G (5th generation mobile networks or 5th generation wireless systems) denotes the next major phase of mobile telecommunications standards beyond the current4G/IMT-Advanced standards.

Complete wireless communication with almost no limitations.

There are lots of improvements from 1G, 2G, 3G, and 4G to 5G in the world of telecommunications.

The new coming 5G technology is available in the market in affordable rates, high peak future and much reliability than its preceding technologies.

It is highly supportable to WWWW (Wireless World Wide Web).

5G VISION-

FEATURES INCLUDES The 5G technology is providing up to 25

Mbps connectivity speed. The 5G technology also support virtual

private network. The uploading and downloading speed

of 5G technology touching the peak. Uploading and Downloading speed of

5G Technology is up to 1Gbps. Very attractive and efficient. Peak data rate is 10Gbps. High Speed and High Capacity.

CONCLUSION According to me the best way to help

all users is to use 5G as the next wireless system and in totally it is safety and secure for public, this the need that demands the solution.

Today’s wired society is going wireless and if it has problem, 5G is answer.

5G technology is going to give tough competition in coming future.
