3g and 4g

KIWI

3g and 4g different speeds that providers produce for their customers. Providers such as AT&T and Verizon are the tops two in this field. The only down side tot his is that many areas, especially not in the city do not have 4g accessible. Even if your phone has the option or says that it is a 4g phone, it also depends on where the 4g towers are. 3g is clearly everywhere. Very rarely a phone such as an iphone does not have 3g. The only time that I have seen an iphone without 3g is when you are literally in the middle of nowhere. Chances are if you have a phone that has 3g, you will be able to search the web or download apps or programs for your phone relatively fast. In today society 3g and 4g are very similar considering there is not 4g towers up everywhere, unless you are in a spot with 4g, a 3g and 4g phone will run n practically the same speed.

3g have a completely different system build then the 4g does. The 3g’s frequency band is 1.8-2.5GHz. It FEC uses turbo codes for error correction and its data throughput is up to 3.1 mbps. 3g also run CDMA 2000, UMTS, EDGE and etc for their service for applications. And also uses packet switching.

On the other hand 4g uses different everything then the 3g. 4g use a 2-8GHz-frequency band. The Concatenated codes are used for error corrections in 4g. The 4g also practically speaking, uses 3 to 5 mbps but potential estimated at a range of 100 to 300 mbps. Wimax, LTE and Wi-Fi are used to run services and applications. The 4g also use packet switching like the 3g but also use message switching.

In comparison to the 3g and 4g you can see that they are similar and different at the same time. Until 4g towers are everywhere you will not be able to see a huge difference between speeds. Right now the main 4g towers are found in major cities and in very large populated areas. The towers will continue to go in on the countryside and spread all over but not until the product spreads more.

As of right now with the speed tests Sprint is wiping everyone out. Sprint has the most 4g towers up and provides that service in more areas then anywhere else. At &T and Verizon are trying to catch up to sprint and get on the some level as them. Just like with any other technology it is only a matter of time before everyone catches up with each other and is on the same boat.
