4 unusual facts about Universal Mobile Telecommunications System


Telecommunications in Israel

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 .

Universal Mobile Telecommunications System

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).


Circuit Switched Data

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.

High-Speed Circuit-Switched Data

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.

Hot mobile

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.

Mobile phone tracking

Using the SIM in GSM and UMTS handsets, it is possible to obtain raw radio measurements from the handset.
