After the normal bureaucratic red-tape associated with such ventures, the very first public LTE networks were available in Oslo and Stockholm December of There is a misnomer we should get out of the way: LTE is not 4G. We can look to T-Mobile as an example.
They put 4G on everything they can, but make no claim to LTE. The benchmark for 4G is also much higher than what we currently see with LTE. Neither is necessarily better, they just operate differently. Carriers knew they needed a marketing strategy for the system updates, so the ITU agreed to let them market it as 4G. Both agencies respect the advancements as significant, so they allowed them to use the moniker. LTE changes the current method of moving data to an internet protocol system.
Think of it as taking the speedbumps off the roads in your city so you can zoom around faster. The major benefit to LTE is that in reduces the latency in data transfer. Both are a method of coding information for travel across airwaves.
Like LTE, it moves larger packets of information at a faster rate. In that respect, everyone is available to use it, and it is widely believed to be a worldwide standard at some point. Frequencies and spectrums are what your device runs on. A true LTE phone will operate on a variety of frequencies. Across the globe, different countries operate on different frequencies. A higher frequency does not denote a better network, either, as a lower frequency is more useful in rural areas.
The best way to understand this is to examine countries in Europe. LTE typically operates on a frequency spectrum of MHz to 2. In short, 4G LTE gives us the ability to utilize and experience the internet in a quicker, richer way. By enabling video viewing and data sharing at a pace not realized before, LTE has turned our smartphones into powerful connected devices that we can carry anywhere.
Yes, there really were three generations of wireless networking technology before 4G. The first generation of mobile technology, which came to be known as 1G, was introduced in the s. An analog technology, it gave us the ability to make and receive calls on mobile phones.
The advent of 2G digital technology in the early s introduced text messaging. The move to 3G in provided network speeds fast enough for the first smartphones. Finally, 4G, with its incredibly fast data-transfer rates, gave rise to many of the connected devices and services that we rely on and enjoy today. From there, Verizon worked feverishly to expand the new network to every corner of the United States. And by , LTE reached 97 percent of the U.
In , Verizon became the first U. LTE Advanced uses carrier aggregation to speed mobile data over the network more quickly than ever before, providing customers with 50 percent faster peak speeds. Today, more than 98 percent of the U. Since the launch of LTE in , Verizon has consistently invested in network infrastructure and implemented the latest technology to improve coverage and throughput speeds. Verizon continues to be at the forefront of 4G networking technology.
The more antennas there are the faster the speed can theoretically be, as the data streams can travel more efficiently. Up to five different signals can be combined at once and with each offering up to 20MHz of bandwidth they can be combined to create a data pipe of up to MHz of bandwidth.
Chances are that you can get LTE-A right now — at least in urban areas. O2 offers similar upgrades in some places, though we have less data on where. We do know though that it has upgraded its 4G network capacity in 33, London postcodes.
While not all smartphones work with LTE-A, the vast majority of modern ones do. They have to at least be a Cat. LTE stands for Long Term Evolution and it is the leading technology that enables the fourth generation of mobile networks or 4G.
It makes efficient use of the network resources, reduces the latency in data transfer, and also reduces the overall network complexity. While LTE is the leading technology that enables 4G, it is not the only one that can allow mobile operators to move to 4G. As a result, LTE can be seen as a step towards streamlining the mobile network evolution. If you look at the high-level network diagram below, you may notice that the radio network in 4G is a bit leaner as compared to that in the 3G UMTS network.
In 2G and 3G networks, the conventional voice calls are only possible through the circuit-switched part of the network. However, there is a circuit-switched fall-back option that mobile operators often use for voice calls.
More about VoLTE in this dedicated post. The data speed you get with LTE depends on which flavour of LTE your mobile operator offers and how they have deployed it. There can be multiple deployment combinations with variations to channel bandwidth and modulation techniques.
