    High Speed Downlink Packet Access (HSDPA) is an enhanced 3G (third-generation) mobile communications protocol in the High-Speed Packet Access (HSPA) family. HSDPA is also known as 3.5G and 3G+ . It allows networks based on the Universal Mobile Telecommunications System (UMTS) to have higher data speeds and capacity.

    Cellular network standards and generation timeline. An Evolved HSDPA network can theoretically support up to 28 Mbit/s and 42 Mbit/s with a single 5 MHz carrier for Rel7 (MIMO with 16QAM) and Rel8 (64-QAM + MIMO), in good channel conditions with low correlation between transmit antennas. Although, real speeds are far lower.

  4. List of UMTS networks - Wikipedia

    en.wikipedia.org/wiki/List_of_UMTS_networks

    The following is a list of mobile telecommunications networks using third-generation Universal Mobile Telecommunications System (UMTS) technology. This list does not aim to cover all networks, but instead focuses on networks deployed on frequencies other than 2100 MHz which is commonly deployed around the globe and on Multiband deployments.

    In December 2007, 190 3G networks were operating in 40 countries and 154 HSDPA networks were operating in 71 countries, according to the Global Mobile Suppliers Association (GSA). In Asia, Europe, Canada and the US, telecommunication companies use W-CDMA technology with the support of around 100 terminal designs to operate 3G mobile networks.

    A point-to-point dedicated channel for transmitting user traffic information between a UE and the network. UL/DL 5.3.1.1.1 [4] 3_LOGICAL PCCH: paging control channel Transfers paging information. Used when the network does not know the location cell of the UE or the UE is in sleep mode. DL 5.3.1.1.1 [4] 2_TRANSPORT BCH: broadcast channel

  9. UMTS frequency bands - Wikipedia

    en.wikipedia.org/wiki/UMTS_frequency_bands

    The UMTS frequency bands are radio frequencies used by third generation (3G) wireless Universal Mobile Telecommunications System networks. They were allocated by delegates to the World Administrative Radio Conference (WARC-92) held in Málaga-Torremolinos, Spain between 3 February 1992 and 3 March 1992. [1]
