Unlicensed 900 MHz ISM (NX915) 3.5.4
Understanding
The 900 MHz ISM Module (NX915) interface provides operation in the 900 MHz unlicensed ISM band.
The module provides long-distance communications with data rates ranging from 125 kbps to 1.25 Mbps,
suitable to interface both Ethernet and Serial controllers such as PLCs, RTUs and SCADA systems. The
module utilizes a combination of FHSS (Frequency Hopping Spread Spectrum), DTS (Digital
Transmission System) and hybrid FHSS/DTS technologies to provide dependable wireless
communications.
The GE MDS NX915 NIC module is a point-to-multipoint, medium speed, long range (>20 miles),
spread-spectrum, wireless data transmission product. It operates as a Frequency-Hopping Spread
Spectrum (FHSS) or a Digital Transmission System (DTS) in the 902 to 928 MHz license-free ISM band.
The NIC can operate as an Access Point, a Remote, or a Store and Forward (SAF) device. It will operate
as an intentional radiator in accordance with FCC Rule Part 15.247 under full modular rules per DA 00-
1407.
The specifications for the 900 MHz NX915 NIC module:
 Frequency Range: 902 to 928 MHz
 Power Output: 20 dBm to 30 dBm in 1.0 dBm steps (DEFAULT = 30 dBm)
 Output Impedance: 50 Ohms
 Permissible Antennas: See Table 3-10 below
 Antenna Connector: TNC female
 Number of Frequency Channels: Selectable 50 to 81 for FHSS, 1 to 20 for DTS
 Channel Separation: 307.5 kHz minimum
 Modulation Type: 2-Level GFSK / 4-Level GFSK
 Data Rates: 125, 250, 500, 1000, 1000W, 1250 kbps
 Peak Frequency Deviation: 1250 kbps / 4-level GFSK: 550 kHz
 Beacon Interval: 10 to 300 ms (DEFAULT is 150)
 Dwell Time: 10 to 400 ms (DEFAULT is 50)
