Digicel Launches CDMA Roaming in the Caribbean

admin — Wed, 14 Mar 2007 10:37:53 +0000

With Leading Pan-Caribbean Operator Becomes First in Region to Offer GSM and CDMA Roaming Capability

Digicel announced that through its partnership with Huawei Technologies, it has launched CDMA roaming in the Caribbean and Bermuda, making it the first GSM operator in the region to simultaneously offer GSM and CDMA on its mobile network.

Huawei has been awarded a CDMA2000 1x EV-DO contract and as a result CDMA travelers coming to the region will now be able to roam on Digicel's network and experience the same high level of roaming service that GSM roamers have come to expect from Digicel. In its initial stage, CDMA roaming is being introduced to five of Digicel's 22 markets, including Jamaica, Bermuda, Aruba, Cayman Islands and Barbados.

"When traveling to the Caribbean, many U.S. mobile customers experience poor service and erratic network coverage from CDMA Caribbean operators," said Mario Assaad, Digicel Group CTO. "Now, they can come to the Caribbean and have reliable mobile service by roaming on our seamless mobile network." » read more »

W-CDMA

admin — Tue, 13 Mar 2007 12:41:06 +0000

W-CDMA (wideband code division multiple access)

The third generation radio standard that will offer voice, data, motion-video and other multimedia capabilities, if adopted by national and international standards organizations. (Cingular)

W-CDMA (Wideband Code Division Multiple Access) is a type of 3G cellular network. W-CDMA is the technology behind the 3G UMTS standard and is allied with the 2G GSM standard.

More technically, W-CDMA is a wideband spread-spectrum 3G mobile telecommunication air interface that utilizes code division multiple access (or CDMA the general multiplexing scheme, not to be confused with CDMA the standard).

History

W-CDMA was developed by NTT DoCoMo as the air interface for their 3G network FOMA. Later NTT DoCoMo submitted the specification to the International Telecommunication Union (ITU) as a candidate for the international 3G standard known as IMT-2000. The ITU eventually accepted W-CDMA as part of the IMT-2000 family of 3G standards. Later, W-CDMA was selected as the air interface for UMTS, the 3G successor to GSM.

Features

Only key features are cited below.

* Supports two basic modes: FDD and TDD modes » read more »

TD-CDMA

TD-CDMA

A 3G proposal combining elements of TDMA and CDMA. (Cingular)

Multiplexing

admin — Tue, 13 Mar 2007 11:36:53 +0000

Multiplexing

When multiple phone calls are carried in the same frequency band at the same time. In wireless, major multiplexing methods include TDMA and CDMA. (Cingular)

In telecommunications, multiplexing (also MUXing) is the combination of two or more higher level channels into a single lower level channel such that a reverse process, known as inverse multiplexing, demultiplexing, or demuxing, can extract the original channels. The individual channels are identifiable by a predetermined coding scheme. (Wikipedia)

IS-95

admin — Tue, 13 Mar 2007 11:22:02 +0000

IS-95

The standard for CDMA. (Cingular)

Interim Standard 95 (IS-95), is the first CDMA-based digital cellular standard pioneered by Qualcomm. The brand name for IS-95 is cdmaOne. IS-95 is also known as TIA-EIA-95.

It is a 2G mobile telecommunications standard that uses CDMA, a multiple access scheme for digital radio, to send voice, data and signaling data (such as a dialed telephone number) between mobile telephones and cell sites.

CDMA or "code division multiple access" is a digital radio system that transmits streams of bits (PN Sequences) . CDMA permits several radios to share the same frequencies. Unlike TDMA "time division multiple access", a competing system used in GSM, all radios can be active all the time, because network capacity does not directly limit the number of active radios. Since larger numbers of phones can be served by smaller numbers of cell-sites, CDMA-based standards have a significant economic advantage over TDMA-based standards, or the oldest cellular standards that used frequency-division multiplexing. » read more »

FWA (fixed wireless access)

admin — Tue, 13 Mar 2007 11:06:51 +0000

FWA (fixed wireless access)

Also known as wireless local loop. (Cingular)

Wireless local loop (WLL), also called radio in the loop (RITL) or fixed-radio access (FRA) or fixed-wireless access (FWA), is the use of a wireless communications link as the "last mile" connection for delivering plain old telephone service (POTS) and broadband Internet to telecommunications customers.

Nowdays there are various types of WLL systems.

These are available in Code Division Multiple Access (CDMA), Global System for Mobile Communications (GSM), IS136 Time Division Multiple Access (TDMA) as well as analog access technologies such as Advanced Mobile Phone System (AMPS), for which there will be independent standards defining every aspect of modulation, protocols, error handling,etc.

Fixed Wireless Terminals or FWT units differ from conventional mobile terminal units operating within cellular networks -such as GSM- in that a fixed wireless terminal or deskphone will be limited to an almost permanent location with almost no roaming or find-me anywhere facilities. » read more »

CDMA2000

CDMA2000

CDMA2000 is a radio transmission technology for the evolution of narrowband cdmaOne/IS-95 to 3rd-generation adding up multiple carriers. See also WCDMA for single carrier/direct spread technology. (Ericsson)

CDMA2000 is a family of third-generation (3G) mobile telecommunications standards that use CDMA, a multiple access scheme for digital radio, to send voice, data, and signalling data (such as a dialed telephone number) between mobile phones and cell sites. It is the second generation of CDMA digital cellular. » read more »

CDMA

admin — Tue, 13 Mar 2007 09:52:40 +0000

CDMA (code division multiple access)

A form of digital phone service that assigns a code to all speech bits, sends a scrambled transmission of the encoded speech over the air and reassembles the speech to its original form at the other end. (Cingular)

A technology for digital transmission of radio signals between, for example, a mobile telephone and a radio base station. In CDMA, a frequency is divided into a number of codes. (Ericsson)

CDMA separates communications by code. Voice is broken into digitised bits, and groups of bits are tagged with a code. Each code is associated with a single call in the network. Groups of bits from one call are randomly transmitted along with those of other calls. Then they are reassembled in the correct order to complete the conversation. (Motorola) » read more »

Air interface

admin — Tue, 13 Mar 2007 09:43:01 +0000

Air interface

The standard operating system of a wireless network. Technologies include AMPS, TDMA, CDMA and GSM. (Cingular)

In mobile communication, the air interface is the radio-frequency portion of the circuit between the mobile station and the active base station. (Wikipedia)

3G

admin — Tue, 13 Mar 2007 09:35:15 +0000

3G (third-generation)

Third generation wireless employing wideband frequency carriers and a CDMA air interface. Networks must be able to transmit wireless data at 144 kilobits per second at mobile user speeds. (Cingular)

3G is a global development of communication standards and technologies. This development will lead to the ability to access multimedia services with your mobile phone. (Nokia)

3G (or 3-G) is short for third-generation technology. It is usually used in the context of cell phones. The services associated with 3G provide the ability to transfer both voice data (a telephone call) and non-voice data (such as downloading information, exchanging email, and instant messaging). » read more »

2G

admin — Tue, 13 Mar 2007 09:34:43 +0000

2G

Second generation of mobile wireless, which utilizes various digital protocols, including GSM, CDMA, TDMA, iDEN, and PDC. (Cingular)

2G (or 2-G) is short for second-generation wireless telephone technology.

The main differentiator to previous mobile telephone systems, retroactively dubbed 1G, is that the radio signals that 1G networks use are analog, while 2G networks are digital. Note that both systems use digital signaling to connect the radio towers (which listen to the handsets) to the rest of the telephone system.

Flavors of 2G

2G technologies can be divided into TDMA-based and CDMA-based standards depending on the type of multiplexing used. The main 2G standards are:

* GSM (TDMA-based), originally from Europe but used worldwide
* IDEN (TDMA-based), proprietary network used by Nextel in the United States and Telus Mobility in Canada
* IS-136 aka D-AMPS, (TDMA-based, commonly referred as simply TDMA in the US), used in the Americas
* IS-95 aka cdmaOne, (CDMA-based, commonly referred as simply CDMA in the US), used in the Americas and parts of Asia
* PDC (TDMA-based), used exclusively in Japan » read more »
