Mobile telephones offer one-to-one wireless communication system that permits two simultaneous transmissions. To make the communication private, every communication set carries a unique telephone number, provided by the service provider.
Mobile networks we presently use are 3G, 4G or 5G. These ‘G’ classifications are basically their generations denoting speed, connectivity and reliability standards derived by the International Telecommunications Union-Radio communications. 4G maybe 10 times faster than 3G and it has more capacity than lower generations such as 2G or 3G. With the introduction of 5G, the game will change tremendously and it will be lightning fast as compared to its ancestors.
LTE or Long Term Evolution is the standard developed for 4G technology. At the same time, other standards were also developed such as UMB (Ultra Mobile Broadband) and WiMax, but could not compete with LTE. The major advantage of LTE to be used by almost all mobile manufacturers as it has an open and interoperable characteristic. Even though every phone is shown following a 4G standard, it uses only LTE technology.
LTE offers many features like:
- High-speed mobile and broadband data
- Telephone services
- Supports public safety functions
- Can assign priorities to customers
- Emergency calls get a higher priority over other calls
- Manage calls in a self-organizing path
4G LTE-A Or LTE+
These are the upgraded version of LTE, resulting in faster downloading and less buffering. It is claimed as faster, stable and having higher bandwidth compared to normal LTE. LTE-A is 2-3 times faster and true to 4G speed as per the design. Multiple antennas can be used to transmit and receive signals, using a technology called MIMO, multi-input, and multi-output. This results in combining the bandwidth signal and providing faster speeds and better coverage. Another information to be noted is that in the AT&T phones, LTE-Advanced service is displayed as 5Ge.
Since new users are being added every day and the 4G network space is limited it gets crowded. They are all sharing a limited amount of space. So there is a growing demand and requirement for a network with a higher speed which will be useful for smart appliances, self-driving cars and complex online games.
5G network will be useful for cell sites that are much closer and ideal for heavily populated areas. One disadvantage for the present users of 4G phones is that they won’t be able to take advantage of this new network. To conclude, LTE-A is almost closer to the 4G standards and can take advantage of the real 4G speed until the network get upgraded to a 5G.
