Everything You Need to Know About 4G

Verizon, Sprint, and  T-Mobile are all providing their subscribers 4G internet connectivity. When we used 3G internet connection on out phone, we felt that it is the fastest internet connectivity that one can avail on their smartphone. However, the 4G network has turned out to be even faster. So let us try to understand more about 4G.

What is 4G?
4G stands for fourth generation wireless. This technology enables you to do VOIP, internet browsing, play games and stream HD videos. Before 4G, 2G and 3G wireless were known to the people. 2G is all about switching from analog to digital transmissions. This technology brought to the world facilities like sending and receiving SMS and email on their phone. 3G technology brought features like global roaming, video calling, sharing the same data network with others and high speed web connectivity. The average speed that you can avail through 3G can range from 600 kilobytes per second to 1.4Megabytes per second. When you compare 3G with 4G, you will be able to achieve the same but with more speed and bandwidth.

According to ITU (International Telecommunication Union), 4G is fast paced internet connection that offers speeds of 100Mbps whichever place you go. This is high mobility for 4G. When it comes to low mobility which means Wi-Fi range, you can get up to 1Gbps speed. However, most of the cellular network service provider’s 4G speeds do not come any close.

Here are some of the technologies that are available in United States. You should be aware of it because these technologies are made available as 4G:

1. WiMax
WiMax is nothing but an extension of Wi-Fi connection which means it offers high speed wireless web connection on a wide range of devices. Sprint is offering this service as 4G which offers 128Mbps HDSPA and 56Mbps HSUPA.

2. LTE (Long Term Evolution)
This is the 4G service offered by Verizon which offers 100Mbps HDSPA and 50Mbps HSUPA. The LTE service cannot be actually called 4G but exclusively refers to 3GPP LTE. LTE Advanced which is yet to launch may meet the 4G standards by offering HSDPA of 1Gbps.

3. HSPA+ (Evolved High Speed Packet Access)
HSPA+ is the 4G service offered by T-Mobile. Sprint and Verizon offers the same service as 3G data. Even though HSPA+ offers high speed connectivity, the speed is much less as compared to LTE and WiMax as it offers 56Mbps HSUPA and 22Mbps HSDPA.
