What Was 3G Wireless Technology?

3G technical specifications

3G was the third generation of wireless technologies. It comes with improvements over earlier wireless technologies, such as high-speed transmission, advanced media access, and global roaming.

3G was primarily used with mobile phones and handsets as a means of connecting the phone to the Internet or other IP networks in order to make voice and video calls, upload and download data, and surf the Web.

The 3G standard has been superseded by the 4G standard, itself eclipsed by 5G services.

History of 3G

3G follows a model of G that the ITU launched in the early 1990s. The model is a wireless initiative called International Mobile Communications 2000. 3G therefore comes right after 2G and 2.5G, the second generation technologies. generation.

2G technologies include, among others, the Global System for Mobile. 2.5G brought standards midway between 2G and 3G, including General Packet Radio Service, enhanced data rates for GSM evolution, Universal Mobile Telecommunications System, etc.

How is 3G better?

3G offered several improvements over 2.5G and previous networks:

  • Several times higher data speed
  • Improved audio and video streaming
  • Videoconference assistance
  • Web and WAP browsing at higher speeds
  • Support for IPTV (TV over the Internet)

Technical specifications

The transfer rate for 3G networks was between 128 and 144 kilobits per second for fast-moving devices and 384 kbps for slower ones, such as walking pedestrians. For fixed wireless LANs, the speed exceeds 2 Mbps.

3G included standards such as W-CDMA, WLAN, and cellular radio, among others.

Terms of use

Unlike Wi-Fi, which you can get for free at hotspots, you had to subscribe to a service provider to get 3G network connectivity. This type of service is often referred to as a data plan or a network plan.

Your device connected to the 3G network via its SIM card (in the case of a mobile phone) or its 3G data card (which can be of different types, such as USB, PCMCIA, etc.), which are generally supplied or sold by the service provider.

These cards allow the device to connect to the Internet when it is within range of a network. In fact, the device is backwards compatible with older technologies, which is why a 3G-enabled phone can benefit from 2G service if it is available while 3G service is not.

The 3G craze of the early 2010s has faded; most devices now support the 4G standard, using 3G as a fallback if 4G connections are unavailable. In some parts of the world, particularly in rural areas, 3G remains a backbone service.

3G follows a pattern of G’s that the ITU started in the early 1990s. The pattern is a wireless initiative called the International Mobile Communications 2000. 3G, therefore, comes just after 2G and 2.5G, the second-generation technologies.

2G technologies include, among others, the Global System for Mobile. 2.5G brought standards that are midway between 2G and 3G, including the General Packet Radio Service, Enhanced Data rates for GSM Evolution, Universal Mobile Telecommunications System, and others.
