Main Differences between LTE & LTE-Advanced
LTE stands for Long Term Evolution.
In Nov. 2004, 3GPP began a project to define the long-term evolution (LTE) of Universal Mobile Telecommunications System (UMTS) cellular technology.
LTE systems have:
Higher performance
Backwards compatible
Wide application
Data Rate:
Instantaneous downlink peak data rate of 100Mbit/s in a 20MHz downlink spectrum (i.e. 5 bit/s/Hz)
Instantaneous uplink peak data rate of 50Mbit/s in a 20MHz uplink spectrum (i.e. 2.5 bit/s/Hz)
Cell range:
5 km - optimal size
30km sizes with reasonable performance
up to 100 km cell sizes supported with acceptable performance
Cell capacity:
up to 200 active users per cell(5 MHz) (i.e., 200 active data clients)
Mobility
Optimized for low mobility(0-15km/h) but supports high speed
Latency (delay)
user plane < 5ms
control plane < 50 ms
Improved broadcasting
IP-optimized
Scalable bandwidth of 20MHz, 15MHz, 10MHz, 5MHz and <5MHz
Co-existence with legacy standards (users can transparently start a call or transfer of data in an area using an LTE standard, and, when there is no coverage, continue the operation without any action on their part using GSM/GPRS or W-CDMA-based UMTS)
LTE Advanced is a mobile communication 4G standard approved by International Telecommunications Union (ITU) in Jan 2012.
LTE-Advanced (LTE-A) is an emerging and, as the name suggests, a more advanced set of standards and technologies that will be able to deliver bigger and speedier wireless-data payloads.
The most important thing to know is that LTE-A promises to deliver true 4G speeds, unlike current LTE networks. You can expect the real-world speed of LTE-A to be two to three times faster than today’s LTE.
To be considered true 4G (also known as “IMT-Advanced”), a mobile network must fulfill a number of benchmarks, including offering a peak data rate of at least 100 megabits per second (Mb/s) when a user moves through the network at high speeds, such as in a car or train, and 1 gigabit per second (Gb/s) when the user is in a fixed position.
The highest possible rates are never achieved in real world conditions. Actual rates will be variable, but we can expect LTE-A to be at least five times as fast as most LTE networks today, and that’s great news for video streaming.
LTE Advanced is supposed to provide higher capacity, an enhanced user experience, and greater fairness in terms of resource allocation.
It does this by combining a bunch of technologies, many of which have been around for some years, so we’re not really talking about the implementation of an entirely new system here.
Lte basic parameters
LTE uses various frequency bands and duplexing techniques to provide high-speed data and peak download speeds of up to 300 Mbps. It supports mobility of up to 350 km/h and uses advanced technologies like OFDM, SC-FDMA, MIMO and turbo coding to achieve low latency and high bandwidth. LTE specifications define channel bandwidths of 1.4, 3, 5, 10, 15 and 20 MHz with modulation schemes of QPSK, 16QAM and 64QAM.

Moción para facilitar que Torremolinos pague la deuda al Ayuntamiento de Málaga
Moción para facilitar que Torremolinos pague la deuda al Ayuntamiento de Málaga Grupo PP Ayuntamiento de Málaga
El Ayuntamiento de Torremolinos debe 17.286.492,90 euros al Ayuntamiento de Málaga por una deuda desde 1988 relacionada con la segregación del municipio. La nueva corporación de Torremolinos ha solicitado reestructurar el calendario de pagos acordado previamente. El Ayuntamiento de Málaga considera irrenunciable el pago pero podría estudiar un nuevo calendario de común acuerdo que reduzca la cuota inicialmente para ir incrementándola progresivamente, manteniendo el mismo periodo de amortización hasta 2040.
