Long-term Evolution (LTE)

Computer NetworkComputer EngineeringMCA

Long – term evolution or LTE is a standard for wireless technology based upon GSM/EDGE and UMTS/HSPA technologies. It offers increased network capacity and speed to mobile device users. It is an extension of the 3G technology for high-speed mobile communications.

LTE-Advanced is an improvement over LTE that meets the criteria of 4G wireless communications as laid down by IMT-Advanced standards. It provides greater speeds and better quality of communications.

Both LTE and LTE-A are used for mobile broadband communications and in VoIP.

Features of LTE

  • LTE was specified by The 3rd Generation Partnership Project (3GPP) release 8 was first adopted in European countries as early as 2009.

  • Experientially, users get improved streaming, downloads and even uploads.

  • LTE has peak data rate of 100 Mbps for downlink and 50 Mbps for uplink.

  • It provides high speed communications with reduced latency.

  • It has scalable bandwidth capacity.

  • The upper layers of LTE are based on TCP/IP. So, it is an all-IP network that supports mixed data, voice, video and messages.

Features of LTE-Advanced

  • LTE-Advanced (LTE-A) meets the specifications of IMT-Advanced standard for 4G technology. It was specified by 3GPP release 10.

  • Its peak data rates are 1000 Mbps for downlink and 500 Mbps for uplink.

  • 3GPP laid down that that all LTE-A devices should be backward-compatible with standard LTE.
