E-UTRA - Features

Features

EUTRAN has the following features:

  • Peak download rates of 299.6 Mbit/s for 4x4 antennas, and 150.8 Mbit/s for 2x2 antennas with 20 MHz of spectrum. LTE Advanced supports 8x8 antenna configurations with peak download rates of 2998.6 Mbit/s in an aggregated 100 MHz channel.
  • Peak upload rates of 75.4 Mbit/s for a 20 MHz channel in the LTE standard, with up to 1497.8 Mbit/s in an LTE Advanced 100 MHz carrier.
  • Low data transfer latencies (sub-5ms latency for small IP packets in optimal conditions), lower latencies for handover and connection setup time.
  • Support for terminals moving at up to 350 km/h or 500 km/h depending on the frequency band.
  • Support for both FDD and TDD duplexes as well as half-duplex FDD with the same radio access technology
  • Support for all frequency bands currently used by IMT systems by ITU-R.
  • Flexible bandwidth: 1.4 MHz, 3 MHz, 5 MHz, 15 MHz and 20 MHz are standardized. By comparison, W-CDMA uses fixed size 5 MHz chunks of spectrum.
  • Increased spectral efficiency at 2-5 times more than in 3GPP (HSPA) release 6
  • Support of cell sizes from tens of meters of radius (femto and picocells) up to over 100 km radius macrocells
  • Simplified architecture: The network side of EUTRAN is composed only by the enodeBs
  • Support for inter-operation with other systems (e.g. GSM/EDGE, UMTS, CDMA2000, WiMAX...)
  • Packet switched radio interface.

Famous quotes containing the word features:

    ““It looks as if
    Some pallid thing had squashed its features flat
    And its eyes shut with overeagerness
    To see what people found so interesting
    In one another, and had gone to sleep
    Of its own stupid lack of understanding,
    Or broken its white neck of mushroom stuff
    Short off, and died against the windowpane.””
    —Robert Frost (1874–1963)

    “However much we may differ in the choice of the measures which should guide the administration of the government, there can be but little doubt in the minds of those who are really friendly to the republican features of our system that one of its most important securities consists in the separation of the legislative and executive powers at the same time that each is acknowledged to be supreme, in the will of the people constitutionally expressed.”
    —Andrew Jackson (1767–1845)

    “Each reader discovers for himself that, with respect to the simpler features of nature, succeeding poets have done little else than copy his similes.”
    —Henry David Thoreau (1817–1862)
