TD-CDMA is used to multiplex streams from or to multiple transceivers.

In Europe, CEPT allocated the 2010-2020 MHz range for a variant of UMTS-TDD designed for unlicensed, self-provided use.
Raanana, Israel: This office was based on Modem-Art, a developer of advanced processor technology for 3G/UMTS mobile devices, which Agere has acquired in 2005.
In GSM/UMTS, the various UTRA standards are air interfaces, and are also (but not exclusively) referred to as "access modes".
Enhanced Data Rates for GSM Evolution (EDGE) (E-GPRS) and Universal Mobile Telecommunications System (UMTS) provide improved radio interfaces with higher data rates, while still being backward compatible with the GSM core network.
Coiler's portfolio of band selective mini and pico repeaters have been developed for use in GSM, DCS and UMTS networks.
Contrary to the classic cell network where UMTS and GSM have a radically different air-interface, GMR-1 3G is still very similar to GMR-1 on the Layer 1 side.
GPRS Tunneling Protocol (GTP) is a group of IP-based communications protocols used to carry general packet radio service (GPRS) within GSM, UMTS and LTE networks.
As a more recent example the Apple iPhone 5 and iPhone 4S support quad-band GSM at 850/900/1,800/1,900 MHz, quad-band UMTS/HSDPA/HSUPA at 850/900/1,900/2,100 MHz, and dual-band CDMA EV-DO Rev. A at 800/1,900 MHz, for a total of 'six' different frequencies (though at most four in a single mode).
HSCSD is also an option in enhanced data rates for GSM evolution (EDGE) and universal mobile telephone system (UMTS) systems where packet data transmission rates are much higher.
In 2011 Mirs was one of two winners (alongside Golan Telecom) for new nationwide UMTS network licenses from the Israeli Ministry of Communications.

It provides nationwide wireless service using UMTS, with supplemented coverage through a domestic roaming agreement with Pelephone (until they reach full coverage) and Integrated Digital Enhanced Network (iDEN) technology (in the 800Mhz SMR band) with PTT service that appeals mainly to businesses and large organizations.
In June 2009, Huawei’s SingleRAN technology was selected by TeliaSonera for Europe’s first GSM/UMTS network with software-defined radio (SDR) technology.
Both companies also offer a 3G mobile access: the Kyivstar is reselling the Ukrtelecom's UMTS services and the MTS is maintaining its own CDMA2000 network in major urban areas.
In Use Case Driven Object Modeling with UML, Stephens outlines an extension to the ICONIX object modeling process which he and co-author Doug Rosenberg termed Design Driven Testing (DDT), a deliberate reversal of Test Driven Development (TDD), a core tenet of XP.
Using the SIM in GSM and UMTS handsets, it is possible to obtain raw radio measurements from the handset.
As a mob unit engaged in a call moves away from a cell site or formally known as Base transceiver station and its signal weakens, the BSC(GSM) or RNC(3G UMTS) will automatically instruct it to tune to a different frequency, one assigned to the newly entered BTS.
Currently, the product line-up consists of connect cards (for example, the GlobeTrotter HSDPA "7.2 Ready" data card), embedded wireless modules (for laptops and/or smartphones), fixed mobile devices (for example, a USB stick providing wireless broadband access via HSPA and UMTS networks) and software.
Because of its support for non-GSM SMS protocols, like UMTS, IS-95 (CDMA), CDMA2000, ANSI-136 (TDMA) and iDEN, the SMPP is the most commonly used protocol for short message exchange outside SS7 networks.
Together with TD-CDMA, it is also known as UMTS-TDD or IMT 2000 Time-Division (IMT-TD).
Telecommunications device for the deaf, a device for text communication along a telephone line
Site sharing includes antennas and mast; this may also hold Base transceiver station (BTS), Node B in UMTS context and common equipment such as Antenna system, masts, cables,ducts, filters, power source and shelter.
As TDD's are increasingly considered legacy devices, with the emergence of modern technologies such as email, texting and instant messaging, text from TDD are increasingly being sent over Text over IP gateways, or other real-time text protocols.
There are currently five companies in Israel which offer cellular communication service (with network technology used listed in brackets): Pelephone CDMA and UMTS , Cellcom GSM and UMTS , Partner Communications (Orange) GSM and UMTS , HOT Mobile (Mirs) UMTS and iDEN , and Golan Telecom UMTS .
Its m2m module portfolio include products in GSM/GPRS, EDGE, UMTS, EV-DO, HSPA, LTE and CDMA products as well as short-range modules in Wi-Fi, ZigBee, Short Range RF (proprietary mesh and point-to-point networks for unlicensed frequency bands), Wireless MBus and GPS/GLONASS (Machine-to-Machine) modules.
3/G/4G routers share Internet connections deriving from modems accessing various wireless broadband technology standards such as LTE, HSPA+/HSUPA/HSDPA, UMTS, and EVDO.
a contemporary UMTS-type Mobile phone, a form of videotelephony that can convey simultaneous audio and video, or
UMTS Forum is very active in different standardization and regulation organizations like ITU, ETSI/3GPP, EC and CEPT (European Conference of Postal and Telecommunications Administrations.
Unlike TD-CDMA (UTRA-TDD 3.84 Mcps High Chip Rate, UTRA-TDD HCR) which complements W-CDMA (UTRA-FDD), it is suitable for both micro and macro cells.
•
The high data speeds of UMTS are now most often utilised for Internet access: experience in Japan and elsewhere has shown that user demand for video calls is not high, and telco-provided audio/video content has declined in popularity in favour of high-speed access to the World Wide Web—either directly on a handset or connected to a computer via Wi-Fi, Bluetooth or USB.
•
UMTS-TDD's air interfaces that use the TD-CDMA channel access technique are standardized as UTRA-TDD HCR, which uses increments of 5 MHz of spectrum, each slice divided into 10ms frames containing fifteen time slots (1500 per second).
UTRA-TDD HCR, an acronym for UMTS Terrestrial Radio Access(UTRA)-Time Division Duplex(TDD) High Chip Rate(HCR), is a 3GPP standardized channel access method based on a combination of TDMA and CDMA (known as TD-CDMA).
The capacitance values are designed for antenna impedance matching in multi-band LTE GSM/WCDMA cellular handsets and mobile TV receivers that operate over wide frequency ranges, such as the European DVB-H and Japanese ISDB-T mobile TV systems.
