On the 900 MHz side, the LG90C’s DNT90 radio provides robust wireless communications. On the cellular side, the LG24C utilizes a dual-band EV-DO modem. In between is the intelligence to allow seamless integration of 900 MHz DNT90 based devices into network or Internet cloud based applications. TCP/IP Internet protocol support reduces the effort to tie LG90C networks into existing sensing and monitoring applications. The LG90C gateway shares the same API as the other RFM2M gateway products, letting you pick the wireless technology that best suits your requirements with only a minimum of changes to your application.

LG90C Operation The LG90C is a robust GPRS cellular gateway for RFM’s DNT90 Frequency Hopping Spread Spectrum (FHSS) radios. The LG90C’s DNT90 radio operates in the 902 to 928 MHz ISM band, transmitting data at 100 kbps with a power output of 40 or 158 mW EIRP. The GPRS cellular modem provides gateway connectivity in the 800, 900, 1800 and 1900 MHz GSM bands. The LG90C includes support for TCP/IP, UDP, ARP, ICMP and DHCP Ethernet protocols, plus ModBus/TCP, HTTP Posts, SimpleDB and XML Internet protocols. This wide array of protocol support greatly reduces the effort to tie LG90C networks into existing sensing and monitoring applications. The unit is packaged in a rugged aluminum enclosure, and ships with a universal wall-plug power supply a 2 dBi 900 MHz dipole antenna, and a fourband GSM dipole antenna. The LG90C is also compatible with RFM’s complete line of 900 MHz antennas, allowing extended operating range where allowed by local regulations. ModBus/TCP support allows the LG90C gateway to seamlessly deliver wirelessly collected sensor readings using the ModBus/TCP standard protocol. The LG90C in conjunction with DNT90-based nodes provide a robust wireless data collection network suitable for a wide range of ModBus automation applications. The switching regulators used in the LG90C support a wide input voltage range, from +9 to +30 Vdc for operation from battery-backed DC power sources. LG90C gateways support point-to-point or point-tomultipoint networks, with store & forward range extension capabilities for large site operations. Copyright © Murata Manufacturing Co.,N.A., Ltd.
