SPREAD SPECTRUM COMMUNICATIONS U TILI O U U U LongRanger 2050 Operator’s Manual PRELIMINARY 18 October 1999 LongRanger 2050 Operator’s Manualii FCC Notice This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide rea- sonable protection against harmful interference in a residential installation. This equip- ment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio com- munications. However, there is no guarantee that interference will not occur in a particu- lar installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: •Reorient or relocate the receiving antenna. •Increase the separation between the equipment and receiver. •Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. •Consult the dealer or an experienced radio/TV technician for help. Changes or modifications not expressly approved in writing by Utilicom Inc. may void the user’s authority to operate this equipment. Utilicom can not accept any financial or other responsibilities that may be the result of your use of this information, including direct, indi- rect, special, or consequential damages.

It provide a wireless, synchronous full duplex, point to point communications at a variety of speeds up to 768 Kbps. Spread Spectrum technology allows operation without a license with output power of up to 28 dBm. The LongRanger 2050 architecture separates the radio into two distinct sections: an Indoor Unit that interfaces with the user equipment, and a watertight Outdoor Unit, which is typically mounted in close proximity to the antenna. The two units are connected with a single coaxial cable, carrying the following signals: 1. DC voltage to power up the Outdoor Unit. 2. Reference frequency for the Outdoor Unit frequency synthesizer. 3. Encoded control signals to select the transmit/receive channels, calibration and built in test functions of the outdoor unit. 4. Intermediate Frequency (transmit and receive)) The cable connecting the Indoor and Outdoor unit can be an inexpensive coaxial cable since the Intermediate Frequency in the cable operates at 325 MHz.

Utilicom LR2050 2.4 GHz Direct Sequence Spread Spectrum Radio FCC ID: LFO-LR2050 The following section will be added to the user manual: 5.3 Antenna Installation Instructions: FCC RF Exposure Limits Antennas used for these transmitters shall be professionally installed on permanent structures for outdoor operations. The installer is responsible for ensuring that the systems using high gain directional antennas are used exclusively for fixed, point-to-point operations. The installer shall mount all transmit antennas so as to comply with the limits for human exposure to radio frequency (RF) fields per paragraph 1.1307 of the Federal Communications Commission (FCC) Regulations . The FCC requirements incorporate limits for Maximum Permissible Exposure (MPE) in terms of electric field strength, magnetic field strength, and power density. Antenna installations shall be engineered so that MPE is limited to 1 mW/cm 2 , the more stringent limit for "uncontrolled environments". Table 2 below specifies the minimu m distance that must be maintained between the antenna and any areas where persons may have access, including rooftop walkways, sidewalks, as well as through windows and other RF-transparent areas behind which persons may be located.
