LTE is a standard for wireless communication and LTE Advanced / LTE Advanced Pro (Cat 6 to Cat 12) 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 travelling.
LTE ( Cat 1 to Cat 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 datarate compare 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 to Cat8)
• LTE Advanced is enhancement to LTE with data rate increase to factor of 10.
• It supports carrier aggregation and higher order MIMO techniques.
• It supports data rate of 1 Gbps in downlink (From eNB to UE) and 500 Mbps in uplink direction (From UE to eNB).
LTE Advanced Pro
• 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 upto 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.
