Wireless Modem

A modem that accesses a private wireless data network or a wireless telephone system, such as the CDPD system is called Wireless Modem. There are varieties of Wireless Modem like HF, VHF & UHF, depending upon the frequency range. Recently many companies have come up with different line of Wireless Modem.

The combination of a GSM mobile phone, notebook PC and PC Card now allows traveling business executives to keep in touch with colleagues, customers, suppliers family or friends by voice, fax or email from virtually anywhere they are likely to find themselves. To meet growing customer demand, GSM operators around the world are deploying new technologies to deliver higher speed wireless access to corporate networks and the Internet.

GPRS brings the packet switching technique used by the Internet to GSM. Ultimately promising data rates of up to 115 kbps, GPRS has launched across many GSM markets during 2001. Beyond GPRS, GSM operators will also have the option to deploy EDGE, a further technological upgrade that will offer data rates of up to 384 kbps.

However, the most significant development on the horizon will be the launch of "third generation" mobile phone networks. Based on IMT2000, a family of technical standards being developed under the auspices of the International Telecommunications Union, third generation - or 3G - will seamlessly integrate voice telephony and the Internet on a single wireless network and offer data rates of 384 kbps to mobile users or 2 Mbps in low-mobility applications such as in-building use.

3G has been launched in Japan during 2001 while 60 or more operators are working towards introducing the new technology to Western Europe from 2004. Licensing of 3G operators is also progressing in central and eastern Europe, Asia and the Americas.

The higher speeds and “always-connected” capabilities of GPRS and third generation networks will stimulate a host of new applications particularly in the field of telemetry. With the potential to add GPRS or 3G modules to virtually any piece of equipment, many advanced mobile phone markets can realistically expect mobile phone penetration to grow beyond one hundred percent of the population.

With mobile networks beginning to deploy new technologies capable of pinpointing the location of users, wireless Internet services will become much more closely tailored to the needs of individuals on the move. The added value of location-based services will make GPRS and 3G wireless networks the preferred means of accessing the Internet, following the example already set in Japan with i-mode. This level of activity has prompted both Yankee Group and Nokia to predict that of one billion mobile phone users by 2003, 600 million will have some form of wireless Internet access.

Other products will only let you connect to the Internet while you are in the digital area. However, Digital Service is NOT available everywhere. There are large parts of United States and Canada where digital coverage is not yet available, especially when traveling in rural areas or between cities. This means that while travelling in such areas you may be able to use your cellular phone for voice communications but you cannot connect your laptop to the Internet.

With Ositech's Cellular modem with the unique CellFlex technology you are assured of Internet connection wherever you can use your Cellular Phone regardless of whether you are in a Digital Service Area or not.
