LTE, LTE-A and LTE-A Pro Evolution

LTE is a standard for wireless communication and LTE Advanced / LTE Advanced Pro (Cat 6 to Cat 19) is a high-speed version of LTE, sometimes marketed as LTE+, 4G+, 4GX,4.5G or 4G LTE Ultra. LTE support varies from country to country, and the speed may vary depending on user location and how fast they’re traveling.

 

LTE (Cat 1~5)

  • LTE has been introduced in 2012 in order to provide high data rate mobile broadband connection.
  • It has been introduced to provide 10 times faster data rate compared to 3G.
  • LTE provides 100 Mbps.
  • LTE has been specified in 3GPP Rel.8.
  • LTE supports carrier bandwidth of 20 MHz.

LTE Advanced (Cat 6~16)

  • LTE Advanced is an enhancement to LTE with data rate increase to the factor of 10.
  • It supports carrier aggregation and higher order MIMO techniques.
  • It supports the data rate of 1 Gbps in downlink (From eNB to UE) and 500 Mbps in uplink direction (From UE to eNB).

LTE Advanced Pro (Cat 17~19)

  • It is enhanced version of LTE Advanced to support higher data rate beyond 3 Gbps.
  • It supports increased Bandwidth, increased efficiency and improved latency.
  • It makes use of both licensed (400 MHz to 3.8 GHz) and unlicensed (5GHz) spectrum to support up to 32 carriers of 20MHz each.
  • It is backward compatible with existing LTE and LTE Advanced devices.
  • It makes use of spectrum more efficiently by increasing number of antenna paths as well as multi beam approach. It serves single radio cell with 16 to 64 antenna paths.
  • It grows network capacity to about 200% without any additional spectrum or base stations.
  • Increased battery life about 10 times than LTE.
