Long-term Evolution (LTE)
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.
