The explosive parallel growth of internet and mobile telephony had a great impact on telecommunication over the past decade. Now, these two entirely different worlds are converging. The union of these two offers the benefit of the
Internet multimedia with the flexibility and mobility of wireless. To provide high speed internet connection without the restriction of boundaries is the main idea.
Third generation mobile technology was developed to achieve this goal. There is another wireless technology which was designed to provide connectivity to the portable devices for local area network which is known as Wi-Fi, had emerged in the last decade.
The goal of this report is to compare 3G and Wi-Fi technologies which are likely to play a role in this convergence. This report will focus on 3G which is IMT-2000 standard versus most popular and widely used wireless LAN standard IEEE 802.11b/g or Wi-Fi. These technologies which have an entirely different philosophy are used by this report as a reference to focus on how wireless internet access might evolve. Billions of pounds of investment have been made to
obtain licenses and to purchase expensive equipment to support high speed data rates. Equipment manufacturers are developing base stations and handsets for large scale deployments for 3G services. On the other hand,Wi-Fi operates in the unlicensed ISM band which does not require huge amount of investment, at least to acquire licenses. Equipment is cheap as compared to 3G base stations. What it does require, is the deployment over a large scale.
This report will not discuss other technologies which are considered to important to provide wireless internet such as WiMAX, Satellite, DVB-S/DVB-RCS or other fixed wireless alternatives. However, this report will provide a brief introduction of mobile generations in the initial sections but detailed comparison of these generations such as 2.5G GPRS or EDGE is beyond the scope of this report. The focus will be on 3G and Wi-Fi (802.11b/g) as a point of discussion that have distinct origins and entirely different histories.
In focusing on 3G and Wi-Fi, we are ignoring many other technologies that are likely to be important in the wireless Internet such as satellite services, LMDS, MMDS, or other fixed wireless alternatives. We also ignore technologies such as Bluetooth or HomeRF, which have at times been touted as potential rivals to Wi-Fi, at least in home networking environments.
Moreover, we will not discuss the relationship between various transitional, or ‘‘2.5G’’ mobile technologies such as GPRS or EDGE, nor will we discuss the myriad possibilities for ‘‘4G’’ mobile technologies. While all of these are interesting, we have only limited space and our goal is to tease out what we believe are important themes/trends/forces shaping the industry structure for next-generation wireless services, rather than to focus on the technologies themselves.7 We use 3G and Wi-Fi as shorthand for broad classes of related technologies that have two quite distinct industry origins and histories.
