Difference between WiFi and 3G

The most common types of Internet connection available today are WiFi and 3G. WiFi connectivity is available in many different areas including your home, in tourist attractions, educational institutions, and any other public location.

3G Internet is provided through mobile service providers and provides high-speed Internet connection over phones or other types of mobile devices. 3G Internet access replaced 2G and was also the precursor to 4G high-speed Internet access .

In today's article, let's dig a little deeper about the difference between WiFi and 3G, as well as the purpose of each type of connection.

1. WiFi technology


WiFi technology provides wireless Internet access through the use of radio waves that transmit signals to a wireless enabled device. The radio waves operate on the 2.4GHz frequency and operate according to standards set by IEEE. This standard is called 802.11 and provides a number of different bandwidth uses denoted by a letter.

The different grades include 802.11a, 802.11b, 802.11g, and most recently 802.11n. The letters a, b, g, n refer to the amount of bandwidth, which determines the performance of the wireless connection.

Currently, WiFi is used everywhere and offers high-speed broadband Internet connection. The WiFi connection was effective when using the latest apps, but the connection was usually slower than 3G or 4G.

2. 3G technology


3G is a technology controlled by a service provider. It is intended for applications based on a wide area network (WAN) . 3G is a more expensive technology than WiFi and can only be installed by service providers. 3G is reliable and has much greater coverage than WiFi. Unlike WiFi, fees are required to connect to a 3G network.

The implementation of 3GPP (Third Generation Partnership Project) marks the beginning of EVDO (Evolution Data Optimized), which increases download speeds by up to 2.4Mbps and UMB (Ultra Mobile Broadband) capable of reaching speeds of up to 288Mbps when download data to your mobile device.

3G mobile broadband offers significant improvements over WiFi access, delivering greater efficiency for video streaming applications, using online meeting applications like Skype and browsing the Internet at higher speeds. WiFi connection.

3. Difference between WiFi and 3G

WiFi and 3G have some differencesWiFi and 3G have some differences

first. WiFi router controls WiFi access. 3G is controlled by the service provider.
2. WiFi offers speeds around 11Mbps to 55Mbps. 3G offers speeds of around 40kbps to 70kbps.
3. WiFi technology is less expensive than 3G technology in terms of usage. 3G is relatively expensive.
4. WiFi is intended for local network-based applications. 3G is for wide area network based applications.
5. Wifi transmits data at 2.4GHz and 5GHz radio frequencies. 3G transfers data at low frequencies, from 850MHz to 1900MHz.
6. WiFi frequency is more stable than 3G frequency. The 3G frequency is relatively less stable.
7. WiFi can be easily set up by installing a wireless LAN on any computer with a wireless adapter. 3G is installed by service providers.
8. The WiFi network is less reliable than the 3G network. 3G is more reliable than WiFi.
9. Usually there is no need to pay to connect to the WiFi network. Pay for 3G network connection.
ten. WiFi is increasingly used more and more. 4G has replaced the 3G network.
