Low Power Radio Modem
Product Description

Low Power Radio Modem

New Way Electronics is specialized in Software Development and Maintainance of wide range of Hand Held Computers for over 10 years. New Way Electronics has developed Vareous Software in Hand Held computers that are used successfully in various cross-functional applications for commercial, Industrial automation, mobile and stands ahead of the competition in innovative race of integrating sophisticated technologies.
The Low Power Radio Modem is an ultra low power transceiver, mainly intended for 315, 433, 868 and 915 MHz frequency bands. It has been specifically designed to comply with the most stringent requirements of the low power short distance control and data communication applications.

A unique UHF RF Radio Modem
The UHF Transceiver is designed for very low power consumption and low voltage operated energy meter reading applications. The product is unique with features like compact, versatile, low cost, short range, intelligent data communication, etc. The product also has 2 / 3 isolated digital inputs and outputs. Necessary command sequences will be supplied to operate these telecommands from the user host.
The radio modem is designed primarily for FSK systems in the ISM / SRD bands at 315, 433868 and 915 MHz, but bands can be easily programmed for operation at other frequencies between 300 MHz and 1000 MHz. The modem supports maximum data rates upto 19.2 kbps.
