The following list highlights some of the special features of the FRH-SD07TU/TB. For more
complete system specifications please refer to p.165 SPECIFICATIONS
.
• Approved under FCC Part 15.247 rules (TU version) and under the European ETS 300 440
standard (TB version) -- no special user license required
• Operating range greater than 1000 feet, line-of-sight -- configurable as a repeater for
extended range of application service area
• Ultra low power consumption. 35mA (Maximum) is achieved at the full-rate operation mode
retaining almost same function and performance in the conventional FRH series radio.
• Newly developed doze waiting reception, ULTRA (Ultra Low-power Transient Radio
Access) mode is implemented to the modem. It enables 2mA current consumption
(average) in the mode.
• 2.4 GHz Direct Sequence Spread Spectrum (DSSS) communication system provides
unsurpassed immunity to interference and RF noise
• Diversity receiving function is employed, which is practically invulnerable to multipath
fading
• Fast switching Time-Division-Duplex (TDD) provides virtual full-duplex communication
between terminal equipments at rates up to 115.2 kbps
• 54 user selectable frequencies allow up to 54 independent networks to operate
simultaneously in the same area
• Single fixed frequency communication or multi-access communication (automatic selection
of an vacant frequency from a defined group of frequencies) allows the user to select the best
frequency use for the application
• Supports 1:1, 1:n, and n:m wireless network topology
• Serial communication interface allows direct connection to a micro controller chip. By
converting its level by the external interface circuit, conformable to RS232C, RS422 and
RS485
• Small size allows easy integration with many systems (1.97" x 1.18" x 0.31" / 50 x 30 x 8
mm)                     
• Supply voltage range is DC voltage in 2.7 to 3.3 V DC
• Communication can be made with other FRH series modems such as 03TU, 04TU and 06TU.
