What is LTE?

LTE a 4G Mobile Communications Standard

LTE is an acronym for Long Term Evolution, and isn’t so much a technology as it is the path pursued to accomplish 4G speeds. Much of the time when your smartphone phone displays the “4G” symbol in the top right corner, it does not really mean it's.4G.When the ITU-R established the minimum speeds for 4G, they were somewhat unattainable despite the huge amount of money tech manufacturers poured into achieving them. In rejoinder, the regulating body determined that LTE, the moniker given to the technology used in quest of those standards, could be labeled as being 4G if it implemented a substantial enhancement over the 3G technology LTE users of the network can experience data speeds that are as much as 10 times quicker than the a 3G network.

LTENetworks immediately started advertising their connections as being 4G LTE, a marketing term that let them claim next-gen connectivity without obtaining the actual required number first; like the United States. claiming they had landed on the moon first because they got pretty darn close and the spaceship that got them close was much better than the previous ship. It’s not total sleight of hand though, despite inconsistent speeds depending on the location and the network, the difference between 3G and 4G is instantly apparent.

How About Speed?

So the burning question is, can a difference between 4G and LTE networks be felt? Is the page loading speed or downloading an app on your handheld much quicker if you have built in LTE technology? Probably not. While the contrast between slower 3G networks and 4G or LTE networks is certainly appreciably quicker, most of the 4G and “true 4G” networks enjoy upload and download speeds that are pretty much identical.

Creating 4G connectivity depends upon two components: a network that can sustain the necessary speeds, and a device with the ability to connect with that network and download information at fast enough speed. Just because a phone contains 4G LTE connectivity inside doesn’t mean you can obtain the speeds you desire, in the same way that purchasing a vehicle that can go 200 mph does not mean you can speed on a 55 mph highway. Before carriers had the ability to truly offer LTE speeds in sizable areas, they began selling phones with the capabilities they would require to reach those desired speeds, and afterwards began rolling out the service on a limited scope. Now that LTE service has become widespread, this isn’t as much of a issue, although if you don’t reside in a major metropolitan area it’s worth looking at to make sure you actually require LTE service where you reside and work. With the increase in popularity, it’s unusual for a provider to charge less if you are not making use of LTE speeds on a routine basis, but you can save money by acquiring an older generation phone with only 3G or 4G connectivity.

Packet-switching vs Circuit-switching

It doesn't matter what the data is or how fast it is transferred, it must be packaged and sent allowing the other points on the network to interpret it. Older networks use circuit-switching technology, a label that refers to the communication method. In a circuit-switching system, a connection is directly established to the target through the network, and the whole of the connection, no matter if it’s a phone call or a file being transferred, happens through that connection.

A quicker connection time, and less chance of the connection being dropped are the advantages of a circut switched network. Newer networks use packet-switching technology, a present-day protocol that takes advantage of the increased number of connected points across the world. In a packet-switching network, information is divided up into small portions which are then sent to your location over whatever currently is the most efficient path. If a node drops from your connection in the circuit-switching networks, you'll need to reconnect, however in a packet-switching network the next available packet will simply search for a different path.

Much of the technology used to create 4G speeds has nothing to do with voice communication. For the reason that voice networks still employ circuit-switching technology, it became crucial to reconcile the contrast between older and newer network architecture. A few diverse methods have been enacted to handle the issue, and the majority of carriers elected to deploy one of two options that sustained their control over the minutes used.

This is done by either allowing voice communication to resort back to circuit-switching technology when employed to make or receive a call, or by employing packet-switching communication for data and circuit-switching for voice simultaneously. A third option is to simply run the speech audio as data over the newer LTE networks, a method that most companies avoid, most likely because it removes their power to easily charge a fee for voice minutes. Voice over LTE is essentially what already waht happens when you make a Skype call or connect to Facetime Audio to another user, having higher-resolution audio and faster connection speeds. ✓
