Wi-Fi is the popular name for the wirelessEthernet 802.11b standard for WLANs.

A Wi-Fi-enabled device, such as a personal

computer, laptop, video game console,Smartphone or digital audio player, canconnect to the Internet within range of awireless network.

Range is about 100 meters.

Wi-Fi uses 2.4 GHz frequency band.

Both are wireless. Which allows user moremobility.

Both are access technologies.

Both offer broadband data services. The speedof which is up to few Mbps.

Both uses microwaves from electromagneticspectrum.

One of the biggest similarity between these twois that they both are used in distance wirelessapplications

The user does not need to be connected or bestatic at a place ,Which revolutionized theinternet by giving the mobility that user need.

Current business models/deployment aredifferent.

Spectrum policy and management areOne of the key distinctions between 3G andWi-Fi.

3G and other mobile technologies use licensedspectrum, while Wi-Fi uses unlicensed sharedspectrum.

Even though they both uses wirelessbroadband technology, the key distinctions are

1. Wi-Fi is used for larger and personalizedapplication whereas 3G is generally forcommercial use mainly by Mobile operators.

2. The speed of 3G is up to 21mbps as of nowwhereas Wi-Fi are able to operate on 100mbpswireless LAN.

1. both technologies are likely to succeed in themarketplace. This means that the future ofWireless Internet lies in both Wi-Fi and 3G.

2. we expect 3G mobile providers to integrate Wi-Fi technology into their networks, which willallow them to transmit data at up to 100mbps.

3. we also expect Wi-Fi to offer competition to 3Gproviders because of the lower entry costs.
