Transcript of LTE

What is LTE?
LTE (

volution) is a wireless broadband technology designed to support roaming Internet access via cell phones and hand-held devices.

It is based on the GSM/EDGE and UMTS/HSPA network technologies, increasing the capacity and speed using a different radio interface together with core network improvements.
LTE 4G?
Some refer to it as a 4G (fourth generation) technology.. BUT!

Future
"Is 4G at this point a new wireless access network, or simply a marketing trick?"
What is LTE Advanced?

The ITU has introduced the term IMT Advanced to identify mobile systems whose capabilities go beyond those of IMT 2000. The IMT Advanced systems shall provide best-in-class performance attributes such as peak and sustained data rates and corresponding spectral efficiencies, capacity, latency, overall network complexity and quality-of-service management. The new capabilities of these IMT-Advanced systems are envisaged to handle a wide range of supported data rates with target peak data rates of up to approximately 100 Mbit/s for high mobility and up to approximately 1 Gbit/s for low mobility.
Goal?

The goals for LTE include improving spectral efficiency, lowering costs, improving services, making use of new spectrum and reformed spectrum opportunities, and better integration with other open standards.
Mobile IP
Mobile IP (or IP mobility) is an Internet Engineering Task Force (IETF) standard communications protocol that is designed to allow mobile device users to move from one network to another while maintaining a permanent IP address.
Mobile IP's biggest advantage is a sustained connection to the Internet while traveling amongst a number of network connection points. In the past, a device would have to reconnect with each node as it moved along, but Mobile IP provides a simple hand-off solution that allows a device to move around seamlessly within a larger network, comprised of many connection points, without once losing their connection.
