Introduction of Mobile Wireless Technology

In this article we discuss about the Mobile wireless technology. The mobile wireless technology industry, as we all know, began its technological progress in 1970. Moreover, cellular concept was first introduced in the 1960s and 1970s. The number of wireless mobile customers is growing at a rate of 50-60% per year.

In addition to mobile voice telephone conversations development of cellular has resulted in the emergence of novel wireless systems. In addtion, standards for a variety of other types of telecommunication traffic. Digital Jalandhar is “The Institute of Digital Learning”.

Why do we use wireless Technology communication?

In other words, The range of wireless technology is what distinguishes them. therefore, Some connectivity, such as Bluetooth and others are available within a few feet. All they can cover a medium-sized office space. Moreover, The mobile phone is capable of covering large areas. On the other hand, Wireless technology allows e-commerce to send and receive data in more flexible and cost-effective ways. After all,The following are some of the advantages of wireless technology: –

• Increased efficiency- Improved communication networks result in faster information transfer.
• Almost never out of touch- There is no need to carry cables or adapters to connect to corporate networks.
• Flexibility- Wireless employees in the office can be connect without having to sit at a computer.
• Cost-effective- Wireless networks are generally less expensive to establish and operate than wired networks.

Wireless Technology Communication History

• As we all know, the 1-G and 2-G eras lasted from the early 1900s through the year 2000, while 3-G first appeared in 2001.
•  NTT DoCoMo launched the first pre-commercial 3G network in Japan in the Tokyo region in May 2001
• NTT DoCoMo launched the first commercial 3-G network on October 1, 2001 utilizing WCDMA technology
•  In 2002, there were 295 million members on 3-G networks around the world at the end of 2007. 4Gon the other hand has only been around for a few years.
•  Therefore, 4-G has been in place since 2008. (not fully implemented.)

Evolution of Mobile Cellular Networks

0-G Technology

• Wireless technology telephones began with 0G and were widely available after World War II.
• Those Days in 1970, The calls were set up by the cell phone provider.
• Modern cellular mobile-telephony technology is based on the mobile radio telephony system.
• Only basic voice communication was possible using Zero Generation technology.

0.5 G Technology

• 0.5 G refers to a group of technologies that have more advanced features than the basic 0G technologies.
• These early mobile telephone systems differed from earlier closed radiotelephone systems.
• They were offered as a commercial service on the public switched telephone network, with their own phone numbers, rather than being part of a closed network like a police radio or taxi dispatch system.
• Loggers, construction foreman, realtors, and celebrities were among the most frequent users. They utilized them to communicate in basic voice.
• In 1971, Finland’s Autoradiopuhelin became the country’s first public commercial mobile phone network.

FIRST GENERATION (1G) Technology

• 1G refers to the first generation of wireless telephone technology, also known as cell phones.
• They were the first analog cell phones, released in 1980.

SECOND-GENERATION (2G) TECHNOLOGY

• 2G is the Second-Generation wireless cell phone, based on digital technology established in the early 1990’s.
• In 1991, 2G was launched in Finland.
• Text messages, image messaging, and MMS were all available via 2G.
• Both the sender and the receiver are more secure with 2G.
• All text messages are digitally encrypted & allowing data to be sent in such a way that only the intended recipient can receive and read it.
• The 2G system makes use of digital mobile access technologies including TDMA and CDMA.
• Digital signals and Voice calls of higher quality are used in 2G technology.

2.5G – GPRS (General Packet Radio Service)

• GPRS is an extension of the existing 2G network to have the capacity of launching packet-based services while enhancing the data rates supported by these networks.
• In Other words, The term “Second and a half-generation” is used to describe 2G-Systems that have implemented a packet-switched domain in addition to a circuit-switched domain.
• GPRS provided data rates from 56 Kbps upto 384 Kbps.
• 2.5G networks may support services such as WAP, MMS, SMS mobile games, and search directory, and internet access.

3G Technology

• It is based on a plan developed by the International Telecommunication Union (ITU) to create a global frequency band in the 2000 MHz area that will support a single, universal wireless communication standard for all countries throughout the world.
• 3G technologies allow network operators to provide a broader choice of more advanced services to their customers while increasing network capacity through enhanced spectral efficiency.
• In addition, Wide-area wireless phone telephone, video calls, broadband wireless data, mobile television, and GPS are among the services available (global positioning system)

3.5 G – HSDPA (High-Speed Downlink Packet Access)

• HSDPA stands for High-Speed Downlink Packet Access.
• It is a mobile telephony protocol that provides a smooth evolutionary path for UMTS-based 3G networks, allowing for faster data transfer speeds.

3.75G – HSUPA (High-Speed Uplink Packet Access)

• The 3.75G refers to the technologies beyond the well-defined 3G wireless/mobile technologies. High Speed Uplink Packet Access (HSUPA) is a UMTS / WCDMA uplink evolution technology.
• HSUPA will initially boost the UMTS / WCDMA uplink up to 1.4Mbps and in later releases up to 5.8Mbps.

4G Technology

• 4G is a concept of interoperability between various types of networks that focuses on high-speed data transfer, such as 0-100MBPS.
• MIMO (Multiple Input Multiple Output) and OFDM (Orthogonal Frequency Division Multiplexing) are two fundamental technologies that have enabled
• WiMAX and LTE are the two most major 4G standards.
• 4G LTE stands for “fourth-generation long term evolution,” and it is capable of providing a very fast and secure internet connection.
• 4-G mobile technology will be capable of downloading at a speed of 100Mbps for mobile access and less mobility of 1GBps for wireless local access.
• The distinction between WiMAX and LTE is that LTE is concerned with IP addresses.
• This is based on the TCP/IP protocol, which is inherited from networking technologies.
• 4G will provide superior security with high data transferability.

4G VoLTE
The term “VoLTE” stands for “Voice Over LTE”. further, This implies that, unlike 4G LTE, all calls, SMS, and web browsing will be sent via data channels exclusively. Therefore, Your Internet data plan will be used to make calls, send SMS, and surf the web. After that, There are a number of reasons why adopting the most recent VoLTE technology over LTE is advantageous:

• Firstly, High-quality voice calls
• Instant switching between voice and video calls
• Better battery life – since there’s no network switching happening.
• High definition video calls
• Quick call connection
• Increased VoIP functionality

FIFTH-GENERATION (5G)

• The radio millimeter bands in the 30 GHz to 300 GHz range.
• further, The 5G range in mmWave testing yielded findings at a distance of about 500 meters from the tower.
• After that , One of the most essential characteristics of 5G is its low latency.
• On the other word, 5G framework is based on scalable orthogonal frequency-division multiplexing (OFDM).
• This favors 5G, which can have latency as low as one millisecond, with realistic estimates ranging from one to ten seconds.
• Moreover, 5G latency is 60 to 120 times faster.

In Conclusion, in the network and Internet fields, wireless technology is becoming increasingly popular and significant. In this post, we will discuss the history of 1G technology to 5G, contrasted the differences between 3G and 4G.
