As estimated eight per cent of Indian customers have two phones registered in their name — having one CDMA phone and the other GSM. Service providers are offering dual mode phones for those who can afford the asking price of Rs. 10,000-12,000. SpiceMobile was the first last year to offer two dual phone models, one of which took two GSM SIM cards and the other, one GSM and one CDMA SIM card.
The user can switch easily from one to the other mode and receive calls on both services. Almost at the same time, Tata Indicom launched a Samsung dual phone which took any combination of SIMs
Engineers at the Bangalore Engineering Development centre of Kyocera Wireless (India), a subsidiary of the San Diego, California-based parent, have helped to craft a dual mode mobile phone which uses a single number to make both CDMA-based cellular calls and Voice over Internet Protocol (VoIP) calls using the nearest WiFi network or hot spot.
SAMSUNG MULTIMODE PHONES:
The first multi-mode mobile from Samsung, the SGH-T578H, supports TD-SCDMA HSDPA/ GSM/GPRS and EDGE networks. The phone was first previewed in Beijing, is powered by a software-defined modem capable of high-speed data transfer, at the rate of 2.8 Mbps, allowing consumers to download several high-quality MP3 files in a quick span of time.It is empowered by NXP’s Embedded Vector Processor (EVP).It also supports quad-band EDGE and dual-band TD-SCDMA with integrated multimedia accelerators.
According to Mr WS Lee, Vice President, Handset R&D Planning, Telecommunication Network Business, Samsung Electronics, “Multimedia and sharing of content will be the drivers for next-generation handsets. The combination of T third generation leading TD-SCDMA technology and NXP’s very innovative EVP technology make them better multimedia partners in costomer point of view.
FORTHCOMING DEVELOPMENTS:
It is expected that as wireless hot spots become more common, WiFi-enabled cellphones will explode in demand. ABI Research predicts there will be more than 300 million in use by 2011 — and, thanks to Kyocera’s Indian researchers, many of them may sport some Indian DNA
