TRACER 4106/4206 System Manual 1. Section 2 Microwave Path Engineering Basics LINE-OF-SIGHT The TRACER 4106 and 4206 systems are designed for operation in the license-free 2.400 to 2.4835 GHz and 5.725 GHz to 5.850 GHz industrial, scientific and medical (ISM) bands, respectively. Radio wave propagation in these bands exhibit microwave characteristics which are ideally suited for point-to-point, line-of-sight communications.
Section 2 Microwave Path Engineering Basics TRACER 4106/4206 System Manual Higher levels of fade margin indicate stronger protection against signal fading and a more reliable link. For most applications, 20 to 30 dB of fade margin should ensure a reliable link. The following sections further discuss the necessary power calculations and their components. 4.

Example Microwave Path with Parameters The following sections further discuss the power budget analysis and its components. Antenna Gain Actual transmit and receive antenna gain values depend strictly upon the physical characteristics of the antennas installed for each link. In other words, the size of the dish determines the antenna gain.
Section 2 Microwave Path Engineering Basics TRACER 4106/4206 System Manual Carrier Wavelength (λ) The carrier wavelength is the physical wavelength of the main RF carrier being used for communication, and is usually approximated at the center frequency of the band (which is 2441.75 MHz for the TRACER 4106 and 5787.5 MHz for the TRACER 4206).

The status LEDs (located on the front panel of the unit) provide information to help determine the necessary troubleshooting action. Recommended actions for resolving possible status LED indicators are contained in this guide. 2.
TRACER 4106/4206 System Manual Section 6 Troubleshooting Guide RF LOW LED If the RF LOW LED is ON (solid red), it is an indicator that the received signal is approaching 0 V of RSSI. This condition is typically indicative of a path or installation problem. Recommended Actions: 1. Verify the far-end transmitter power setting is the value that the link planning budget requires. 2. Check all coaxial cable connectors for solid connections. Check for water and corrosion around any of the connectors.
Section 6 Troubleshooting Guide TRACER 4106/4206 System Manual Blue Alarm A remote alarm (alarm indication signal or AIS) is generated by the attached equipment. The root cause must be determined at the attached equipment. A typical cause of a blue alarm is a lack of input to a CSU. Recommended Actions: 1. Verify the input to any attached data equipment.
