MOTOROLA has revolutionised the cellular phone industry with its offering of the world's lightest portable phones across all categories - European digital GSM, American digital TDMA, Analog AMPS and ETACS. The Micro TAC Elite handphone is the company's most advanced and lightest product in the AMPS and ETACS categories at only 113 grams. The Micro Digital Elite weighing in at 187 grams is the lightest cellular telephone in the North American digital TDMA category while the International 8200, weighing in at 149 grams, is the world's lightest handphone in the GSM category. Motorola's latest additions to its handphone series mark a significant breakthrough in weight reduction while achieving the same quality, performance and durability. All Motorola handphones are subjected to a series of tests designed to simulate a variety of extremes including temperature, shock, vibration and dust, according to Cedric So, the director of marketing of Motorola's HK operations. 'We may be building lighter phones, but not at the expense of structural rigidity or reliability,' Mr So said. 'Our breakthrough technology in the cellular phone industry brings us stronger, lightweight materials and even smaller electronic components, which enable us to provide customers with the most technologically advanced and innovative products.' 'We have packaged these phones with features that provide the sort of flexibility and convenience which handphone users need and want,' he added. The International 8200 is the first of a new generation of GSM phones with VibraCall and the all-new user interface called Personality - an easy method of accessing and building the telephone's features to suit users' individual needs. Other features of the International 8200 are: SMS messaging, which allows users to access text messages using a dedicated key; personal pager-type messages and general cell broadcast; and caller-line identification (CLI) which instantly identifies callers by displaying their phone numbers on the screen. The Micro Digital Elite features the Elite Series display with menu icons that help users easily screen the phone's features. This TDMA model is also similar to the Micro TAC Elite in that they both offer an enhanced user interface, two rows of alpha characters and dedicated signal and battery charge metres among other features. The Micro Digital Elite is also compatible with future TDMA network services such as Caller ID, Voice Privacy, Voice Mail Message Waiting Indicator, Authentication and Distinctive Ring. Included in this lightweight package is the popular VibraCall feature. VibraCall offers consumers the ability to receive calls in a vibration alert mode instead of through the usual ringer. Cellular phone subscribers in the Asia-Pacific region make up almost 15 per cent of the world's total subscribers. The region leads the world in cellular handphone subscription, averaging almost 76 per cent growth on a year-to-year basis over the past five years in comparison with a 45 per cent growth rate in the rest of the world. There are an estimated 450,000 cellular handphone users in Hong Kong.
