What are the advantages and disadvantages of Long Term Evolution (LTE) technology?

The Long Term evolution is one of the standards for high speed wireless communication for mobile devices and data terminals based on the GSM and HSPA technologies. It helps in increasing the capacity and speed by using a different radio interface with core network improvement.

LTE is an upgrade path for carriers with both GSM/UMTS networks and CDMA 2000 networks. The LTE frequencies and bands used in different countries mean that only multi band phones are able to use LTE in all countries where it is supported.

There are two types of LTE which are as follows −


Long-Term Evolution time-division duplex also referred to as TDD LTE is a 4G telecommunication technology and Long-Term evolution frequency-division duplex.

The differences between LTE-TDD and LTE-FDD are uploaded and downloaded, and frequency spectra the networks are deployed in.


The features of LTE are as follows −

  • Download rates are up to 299.6 Mbit/sec and upload rates up to 75.4 Mbit/sec depending on user equipment category.

  • Low data transfer latencies, lower latencies for handover and connection set-up time than with previous radio access technologies.

  • Support for all frequency bonds currently used by IMT systems by ITU-R.

  • LTE supports at least 200 active data clients in every 5Mhz cell.

  • Packet switched radio interface.


The advantages of LTE are as follows −

  • LTE dedicated for packet switched operations.

  • LTE supports data as well voice.

  • LTE achieves a higher data rate.

  • LTE mobile terminals have low power during transmissions

  • Battery life has to be enhanced on the user side.

  • LTE downloads the files faster,

  • Decrease traffic load on the LTE network.

  • Increases total user capacity of the LTE network.

  • Increases user experience.

  • Latency is very low in LTE.


The disadvantages of LTE are as follows −

  • The present mobile phones cannot be used to access LTE network features

  • LTE network is a new network which requires installation of equipment and antennas to make it operational.

  • It takes time to stabilize and have LTE signals available everywhere.

  • The LTE system is complex.
