3G network is a mobile communications standard that allows mobile phones, computers, and other portable electronic devices to access the Internet wirelessly. It is the upgrade of 2G and 2.5G GPRS networks for faster internet speed.
Origin of 3G Network and Improvements
Third-generation mobile networks, or 3G, came to the U.S. in 2003 introducing a minimum consistent Internet speeds of 144 Kbps (kilobytes per second).
Right now, there are now so many varieties of 3G, though, that a “3G” connection can get you Internet speeds anywhere from 400 Kbps to more than ten times that. 3G telecommunication networks support services that provide an information transfer rate of at least 0.2Mbit/s.
Later 3G releases often denoted 3.5G and 3.75G, also provide mobile broadband access of several Mbit/s to smartphones and mobile modems in laptop computers. This ensures it can be applied to wireless voice telephony, mobile Internet access, fixed wireless Internet access, video calls and mobile TV technologies.
As its core feature, 3G networks offer greater security than their 2G predecessors. This is done by allowing the UE (User Equipment) to authenticate the network it is attaching to, the user can be sure the network is the intended one and not an impersonator.
3G in Africa
According to ITweb Africa, even though 3G network services are available in some major African cities, it is not expected that full coverage in the sub-Saharan countries is achieved until 2020. Africa remains densely populated with most countries still waking up to the burgeoning tech era.
Applications of 3G Network
Some of the notable applications of 3G include
- Global Positioning System (GPS)
- Location-based services
- Mobile TV
- Video Conferencing
- Video on demand.
How To Speed Up 3G Network On An Android-Powered Device
If data connection on an Android device is slow, you could try any of the following steps to speed up the network connection.
1. Clear the cache in your device
Cache files would always contain unimportant resources in the smartphone, thus slowing down the device. So, head towards Settings > Storage and clear the cache.
2. Stop the images in your browser
The images take more time to load which eventually makes the internet slow
Unless you need to view images on the web page you’re visiting, you can speed up network connection by switching your browser into “Text only mode”,
This setting is usually found in the settings menu of the browser and will prevent the browser from loading any images, thus making the 3G connection much better in the Android Smartphone.
3. Uninstall or Delete the memory hogging apps
Unwanted apps that are present in the device and occupying a great amount of storage space can be removed to speed up the 3G connection.
Advantages of 3G
- 3G creates room for advanced technology, use of different media to convey information and also helps large range or variety of mobile phone to make use of network at a particular time and makes users also have the speed for their communication.
- 3G helps users to be able to see a video or satellite-based program like TV channels using 3G technology at a more easier and faster rate.
- The technology seamlessly supports video calls on supported devices across borders.
- Big multimedia messaging can be done over a 3G network
- 3G networks are easier and cheaper to set up for providers even though users have to pay a higher tariff
Disadvantages of 3G Network
- Despite all the benefits, it is known that 3G network usage may be very costly. It’s plan prices for cell phones are much higher than that of 2G.
- Power consumption on the devices is higher.
- The radiation of magnetic waves generated during the heavy use of the wireless system has been proven to affect human life adversely. Using 3G technology for a long time can affect our brains badly.
While the era of 3G devices is quickly fading away in some parts of the world, the technology is still a popular choice in many parts of the globe especially Africa.
The 4g networks will no doubt, come to mainstream in the coming years but would be blazing the trail started by the innovative third-generation mobile network technology.
