3G vs WiFi

Abstract

The two most essential phenomena impacting telecommunications over the past decade have been the explosive parallel growth of both the internet and mobile telephone services. The internet made the benefits of data information to the masses with email, the web, and e-commerce; at the same time as free help has enabled “observe-me everywhere/continually on” telephony. The net helped accelerate the fashion from voice-centric to data-centric networking.

Data already exceeds voice visitors, and the facts share keeps to develop. Now, these worlds are converging. This convergence gives the benefits of latest interactive multimedia services coupled to the power and mobility of wireless. To obtain the full capacity of this convergence, however, we want broadband to get right of entry to connections.

3G vs WiFi Introduction

Here we investigate and contrast two technologies that are likely to play significant roles: The 3rd Generation mobile (“3G”) and Wireless Local Area Networks. The preceding describes a natural evolution and enlargement of the business models of existing mobile providers. In contrast, the WiFi program would leverage the sizeable connected base of WLAN infrastructure now in place. We use 3G vs WiFi as shorthand for the broad categories of related technologies that have two close distinct activity origins and histories.

Speaking broadly, 3G offers a vertically – integrated, top-down, service – provider approach to delivering wireless internet access, while WiFi provides an end – user-centric, decentralised approach to service provisioning. We are using these two technologies to focus our speculations on the potential tensions between these two alternative worldviews. Wireless future will include a mix of heterogeneous wireless access technologies.

Moreover, we expect that the two worldviews will converge such that vertically-integrated service providers will integrate WiFi or other WLAN technologies into their 3G or wireline infrastructure when this makes sense. The multiplicity of potential wireless access technologies and business models provided some hope that we may be able to realise robust facilities-based competition for broadband local access services. If this occurs, it will help solve the “last mile” competition problem that has been deviled telecommunication policy.

SOME BACKGROUND ON WiFi AND 3G

3G:

The Technology is 3G is used for free assistance providers. Mobile services are implemented by service providers that own and operate their wireless networks and sell mobile services to and -users. Mobile service providers use licensed spectrum to provide wireless telephone coverage over some relatively large contiguous geographic service area. Today it may include the entire country.

From a user’s perspective, the key feature of mobile service is that it offers ubiquitous and continuous coverage. To support the service, mobile operators maintain a network of interconnected and overlapping mobile base stations that hand-off customers as those customers move among adjacent cells. Each cellular base station may support the user’s up to several kilometres away. The cellular towers are connected to each other by a backhaul network that also gives interconnection to the wireline Public Switched Telecommunications Network (PSTN) and different services.

Mobile machine operator owns the stop-to-give up a network from the bottom stations to the backhaul networks to the factor of interconnection to the PSTN. Third Generations (3G) cell technology will assist better bandwidth virtual communications. To extend the range and capability of statistics services that can be supported by using digital cellular systems, service companies will upgrade their networks to one of the 3G technologies which could assist records fees of from 384Kbps up to 2Mbps.

WiFi

The popular name is WiFi given for the wireless Ethernet 802.11b standard for WLANs. WiFi permits collections of PCs, terminals, and different allotted computing devices to share sources and peripherals inclusive of printers get admission to servers and so forth. One of the maxima recommended LAN technologies changed into Ethernet.

HOW ARE WiFi AND 3G SAME

From the preceding discussion, 3G and WiFi address utterly different user might need in quite distinct markets that do not overlap. While this was undoubtedly more true about earlier generations of mobile services when compared with wired LANs or previous versions of WLAN”s, it is increasingly not the puzzle. The last-user does not mind what technology is used to help his service. What matter is that both of these techniques are providing platforms for wireless access to the internet and other communication services.

4G Wireless Systems Summary 4G Wireless Systems or Fourth generation wireless system is a packet switched wireless network with broad area coverage and high throughput. It is designed to be cost-effective and to provide high spectral efficiency. The 4g wireless uses Orthogonal Frequency Division Multiplexing (OFDM), Ultra Wide Radio Band (UWB), and Millimeter wireless. The […]
