  3. UMTS frequency bands - Wikipedia

    en.wikipedia.org/wiki/UMTS_frequency_bands

    The main UMTS bands are in bold print. Networks on UMTS-bands 1 and 8 are suitable for global roaming in ITU Regions 1, 2 (some countries) and 3. Networks on UMTS bands 2 and 4 are suitable for roaming in ITU Region 2 (Americas) only. Networks on UMTS band 5 are suitable for roaming in ITU Regions 2 and 3 (single countries).

    For technical details on UMTS and a list of its designated operating frequencies, bands, and their common names, see UMTS frequency bands. Networks on the global UMTS-bands 1 and 8 are suitable for global roaming in ITU Regions 1, 2 (some countries) and 3. Networks on UMTS-bands 2 and 4 allow roaming in ITU Region 2 (Americas) only.

  6. List of wireless network protocols - Wikipedia

    en.wikipedia.org/wiki/List_of_wireless_network...

    Both EDGE and 1xRTT are 3G standards, as defined by the ITU, but are usually marketed as 2.9G due to their comparatively low speeds and high delays when compared to true 3G technologies. True 3G systems such as EV-DO , W-CDMA (including HSPA and HSPA+ ) provide combined circuit switched and packet switched data and voice services from the ...

    It provides extensions to the existing HSPA definitions and is therefore backward compatible all the way to the original Release 99 WCDMA network releases. Evolved HSPA provides data rates between 42.2 and 56 Mbit/s in the downlink and 22 Mbit/s in the uplink (per 5 MHz carrier) with multiple input, multiple output (2x2 MIMO) technologies and ...

  8. Node B - Wikipedia

    en.wikipedia.org/wiki/Node_B

    In contrast with GSM base stations, Node B uses WCDMA/TD-SCDMA as the air interface technology. As in all cellular systems, such as UMTS and GSM, the Node B contains radio frequency transmitter(s) and the receiver(s) used to communicate directly with mobile devices, which move freely around it. In this type of cellular network, the mobile ...

  9. Radio Bearer in UMTS - Wikipedia

    en.wikipedia.org/wiki/Radio_Bearer_in_UMTS

    In mobile telephony a bearer service is a link between two points, which is defined by a certain set of characteristics. Whenever user equipment (UE) is being provided with any service (CS/PS service), the service has to be associated with a Radio Bearer specifying the configuration for layer 2 and physical layer in order to have its QoS clearly defined.
