The trend of progress in mobile communication in Nigeria is quite impressive, from the analog cellular generation to the 3.5G. The 1G gives birth to 2G because of its limitation.
2G was not suitable for web browsing and multimedia application. 2.5G system was introduced to enhance the data capacity of GSM and mitigate some of the limitation of 2G. This system added packet data capacity to GSM Network and the most important technology this era were GPRS and WAP. WAP defines how web pages over limited bandwidth wireless channel to small screen built into new mobile telephones while GPRS defines how to add IP support to the existing GSM infrastructure. GPRS provide both a means to aggregate radio channels for high data bandwidth and the additional servers required to bad off packet traffic from existing GSM circuit.
Because the real killer application is the internet, 3G thinking had to evolve. 3G applications provide the fastest means of accessing the internet. The current fast@link of MTN and other networks in Nigeria integrate 3G for fast download of application from the internet.
Sometime, if in area where 3G is not available, you may have problem if you are using 3G. Visit www.immyreview.com to read how to resolve problems relating to your fast@link modem.
The era of 4G is being expected as this technology will integrate all mobile technologies like GSM, GPRS, WAP, etc.
