Curious about the LTE symbol on your smartphone? It’s one of the many wireless standards that allow you to communicate while you’re at it. But what does LTE mean and how is it different from 5G?
A 4G standard
LTE or Long Term Evolution is a 4G wireless broadband standard used by mobile operators to provide data and voice services to your phone. It provides faster internet speeds and lower latency than 3G. As a result, you can play videos, play games, and make high-speed data transfers in the palm of your hand.
LTE is mainly used in smartphones and mobile hotspots. But you’ll also find technology in some smartwatches, tablets, laptops, and other devices.
Although LTE is often marketed as 4G LTE, it technically does not meet the criteria for a 4G wireless service established by the ITU Radiocommunication Sector (ITU-R). ITU-R is a unit of the International Telecommunication Union, and is responsible for developing communications standards, such as 4G. According to ITU-R, a true 4G network offers maximum data transmission speeds of at least 100 Mbps on the go and at least 1 Gbps while stationary.
However, when mobile operators could not reach these speeds, ITU-R relaxed the requirements for LTE to be marketed as 4G technology. The ITU-R said any wireless technology that provides “a substantial level of performance and capability improvement” over the initial 3G network could also be considered 4G.
What are LTE Advanced and LTE Advanced Pro?
LTE Advanced and LTE Advanced Pro are enhanced versions of the LTE standard and are able to provide even faster internet speeds. Theoretically, LTE Advanced can offer a maximum data download speed of 1 Gbps, and Advanced Pro can reach up to 3 Gbps. As a result, both LTE Advanced and Advanced Pro meet the technical requirements of real 4G.
Fortunately, both LTE Advanced and LTE Advanced Pro are compatible with earlier versions, and normal LTE devices can work with these networks. But unfortunately, you will not reap the benefits.
Many LTE networks around the world have already been upgraded to LTE Advanced. And it is represented by LTE +, 4G + or LTE-A symbols on the phone, instead of the usual LTE or 4G.

How does LTE work?

Cellular standards have traditionally used circuit and packet switching networks to provide voice and data services to their consumers. While a circuit-switched network establishes a dedicated connection to the person at the other end and maintains the connection until a call is completed, a packet-switched network, on the other hand, uses data packets to transmit information. from one device to another. a digital network. These data packets are free to use the path of least resistance to reach their destination and do not need a dedicated line.
Unlike 2G and 3G technologies, LTE uses a fully packet-switched network. As a result, there is no circuit change for making voice calls. Instead, VoLTE or LTE voice-over is used to handle voice calls. That said, LTE supports the Circuit Switched Backup (CSFB) option to allow voice calls over existing 3G and 2G networks when a phone does not support VoLTE or LTE is not available. In fact, during the early LTE implementations, operators frequently used CSFB. But VoLTE is pretty common now.
LTE makes efficient use of existing network bandwidth to provide faster internet speeds and low latency. This is possible thanks to technologies such as MIMO or Multiple Input Multiple Output, Carrier Aggregation, multi-carrier modulation and more.
LTE vs. 5G

While LTE remains a dominant cellular technology standard worldwide, 5G or fifth-generation wireless broadband technologies are gaining momentum. Several wireless carriers around the world, including North America, are deploying their 5G networks that promise faster internet speeds, reliability and bandwidth.
Therefore, with a 5G network, you can expect to upload or download data at a much faster speed than LTE. It will also allow you to enjoy data and bandwidth-intensive applications and services, such as cloud games, high-resolution streaming, and more.
Fifth-generation networks are theoretically capable of delivering download speeds of up to 10 Gbps. However, these higher data rates are only possible with high-frequency 5W mmWave bands. 5G can also use frequency bands below 6GHz, but the Internet speeds in these frequency bands will not be as high as mmWave 5G, though even higher than LTE speeds.
And as 5G networks are still in their growth phase, it will take time for them to mature as LTE has matured over the years. Also, because 5G is a new technology and is not backward compatible, like any previous generation of network, you will need a 5G compatible device to experience it. For example, your LTE phone will not be able to connect to a 5G network.
However, while 5G offers several advantages over LTE, it is not yet ready to replace LTE. So over the next few years, at least, we’ll see 5G and LTE coexist and complement each other.
