XPress Telecom
XPress Telecom was a wireless telecommunication operator in Jordan. It has been shut down because of financial problems. It holds a digital trunking radio system license from the country's telecommunication regulatory body, the TRC; the technology used is Motorola's proprietary iDEN technology operated on the SMR-800 frequency band. Its offering mostly targeted the corporate market with an array of services needed in such sector including; professional radio service (also known as Push-To-Talk or PTT), regular mobile telephony and messaging services along with A-GPS based tracking services and wireless-data services. They do also offer prepaid service for the individual customers. XPress Jordan ceased trading in 2010. XPress's sister company Bravo Telecom operates the same system in neighboring Saudi Arabia, one advantage of that is that customers of either network can place international push-to-talk calls, similar service is available between Sprint Nextel iDEN network subs ...

Amman, Jordan
Amman (; ar, عَمَّان, ' ; Ammonite: 𐤓𐤁𐤕 𐤏𐤌𐤍 ''Rabat ʻAmān'') is the capital and largest city of Jordan, and the country's economic, political, and cultural center. With a population of 4,061,150 as of 2021, Amman is Jordan's primate city and is the largest city in the Levant region, the fifth-largest city in the Arab world, and the ninth largest metropolitan area in the Middle East. The earliest evidence of settlement in Amman dates to the 8th millennium BC, in a Neolithic site known as 'Ain Ghazal, where the world's oldest statues of the human form have been unearthed. During the Iron Age, the city was known as Rabat Aman and served as the capital of the Ammonite Kingdom. In the 3rd century BC, Ptolemy II Philadelphus, Pharaoh of Ptolemaic Egypt, rebuilt the city and renamed it "Philadelphia", making it a regional center of Hellenistic culture. Under Roman rule, Philadelphia was one of the ten Greco-Roman cities of the Decapolis before being di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telecommunication
Telecommunication is the transmission of information by various types of technologies over wire, radio, optical, or other electromagnetic systems. It has its origin in the desire of humans for communication over a distance greater than that feasible with the human voice, but with a similar scale of expediency; thus, slow systems (such as postal mail) are excluded from the field. The transmission media in telecommunication have evolved through numerous stages of technology, from beacons and other visual signals (such as smoke signals, semaphore telegraphs, signal flags, and optical heliographs), to electrical cable and electromagnetic radiation, including light. Such transmission paths are often divided into communication channels, which afford the advantages of multiplexing multiple concurrent communication sessions. ''Telecommunication'' is often used in its plural form. Other examples of pre-modern long-distance communication included audio messages, such as coded drumb ...

Jordan
Jordan ( ar, الأردن; tr. ' ), officially the Hashemite Kingdom of Jordan,; tr. ' is a country in Western Asia. It is situated at the crossroads of Asia, Africa, and Europe, within the Levant region, on the East Bank of the Jordan River. Jordan is bordered by Saudi Arabia to the south and east, Iraq to the northeast, Syria to the north, and the Palestinian West Bank, Israel, and the Dead Sea to the west. It has a coastline in its southwest on the Gulf of Aqaba's Red Sea, which separates Jordan from Egypt. Amman is Jordan's capital and largest city, as well as its economic, political, and cultural centre. Modern-day Jordan has been inhabited by humans since the Paleolithic period. Three stable kingdoms emerged there at the end of the Bronze Age: Ammon, Moab and Edom. In the third century BC, the Arab Nabataeans established their Kingdom with Petra as the capital. Later rulers of the Transjordan region include the Assyrian, Babylonian, Roman, Byzantine, Rashidun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trunked Radio System
A trunked radio system is a two-way radio system that uses a control channel to automatically assign frequency channels to groups of user radios. In a traditional half-duplex land mobile radio system a group of users (a ''talkgroup'') with mobile and portable two-way radios communicate over a single shared radio channel, with one user at a time talking. These systems typically have access to multiple channels, up to 40-60, so multiple groups in the same area can communicate simultaneously. In a conventional (non-trunked) system, channel selection is done manually; before use the group must decide which channel to use, and manually switch all the radios to that channel. This is an inefficient use of scarce radio channel resources because the user group must have exclusive use of their channel regardless of how much or how little they are transmitting. There is also nothing to prevent multiple groups in the same area from choosing the same channel, causing conflicts and 'cross-talk'. ...

IDEN
Integrated Digital Enhanced Network (iDEN) is a mobile telecommunications technology, developed by Motorola, which provides its users the benefits of a trunked radio and a cellular telephone. It was called the first mobile social network by many technology industry analysts. iDEN places more users in a given spectral space, compared to analog cellular and two-way radio systems, by using speech compression and time-division multiple access (TDMA). History The iDEN project originally began as MIRS (Motorola Integrated Radio System) in early 1991. The project was a software lab experiment focused on the utilization of discontiguous spectrum for GSM wireless. GSM systems typically require 24 contiguous voice channels, but the original MIRS software platform dynamically selected fragmented channels in the radio frequency (RF) spectrum in such a way that a GSM telecom switch could commence a phone call the same as it would in the contiguous channel scenario. Operating frequencies ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saudi Arabia
Saudi Arabia, officially the Kingdom of Saudi Arabia (KSA), is a country in Western Asia.
