The Mobile Telephone A Mobile Telephone (also known as a Cellular Telephone) is defined as a 'portable electronic device for the purpose of telecommunications over long distances.’  There are different kinds: 

◦ Standard phones--multimedia phones that allow users to download music, ringtone, watch TV and videos and send multimedia messages ◦ Smartphones( blackberry, Nokia N series) which are relatives of the PDA offer computing capabilities. These Include the iphone that presents whole Web pages via its safari browser.



iPod an MP3 player and Internet device which could also be used as a mobile device. ◦

Evolution of the Mobile Telephones

 The

mobile industry currently offers 1G, 2G and 3G devices. 1G is being phased out while 4G devices are still under development but countries such as Japan and China are already using 4G technology.



The radio telephone system contained one central antenna tower per region. The central antenna required radio phones to have a powerful transmitter, capable of transmitting up to 50 miles. The number of radio telephones per region was limited by the number of available channels.

2G 1G 0G

The radio telephone system preceded modern cellular mobile telephony technology (1G).

Unlike closed radio systems, radio telephones were connected to the public telephone network and were typically mounted in cars, trucks, and briefcases. 



The 1G cellular telephone system divided cities into small cells. This division allowed extensive frequency reuse across a city, allowing millions to use cell phones simultaneously. 1G cell phone technology encompassed analog standards introduced in the 1980s and continued until replaced by 2G digital cell phones.

Second Generation Cellular Communication (2G)

4G 2G (GSM standard)—GPRS 

3G 2G 1G 0G

(General Packet Radio Service was introduced in 2001. It added packet switching protocols to mobile communications technology and TCP/IP thus making possible the reading and sending of e-mails, instant messaging (IM), and browsing the Internet. SMS or short message service is heavily used.  2.5 G added MMS. 

3G

 

2G

3G networks provide the ability to transfer voice data and non-voice data (music downloads, emails and instant messaging) over the same network simultaneously. 3G networks deliver broadband capacity and support greater numbers of voice and data customers at lower incremental costs than 2G.

3G—UMTS (Universal Mobile Telecommunications System)

Standards:

- W-CDMA: Wideband Code Division Multiple Access - EVDO: Evolution-Data Optimized 

3G vs. 4G 

Less Complexity, Faster Transmission Unlike the 3G networks which are a combination of circuit switched and packet switched networks, 4G will be based on packet switching only. This will allow lowlatency data transmission.



3G Leading U.S. Carrier 3G EVDO network currently averages 400 to 700 Kbps with peak rates up to 2 Mbps.

4G International Carrier is testing 4G communication at 100 Mbps while moving, and 1 Gbps while stationary.

Fourth Generation Cellular Communication (4G)

4G is not one defined technology or standard, but rather a collection of technologies and protocols aimed at creating fully packet-switched networks optimized for data. 4G networks are projected to provide speeds of 100 Mbps while moving and 1 Gbps while stationary.



3G

4G networks will provide a wireless alternative for broadband access to residential and business customers.

2G

In addition, 4G will provide the first opportunity for broadband access in remote locations without an infrastructure to support cable or DSL access.
