In addition to the information contained in this chapter, additional safety-related information can be found in other parts of the document. IMPORTANT: This is not an exhaustive list of all the precautions and safety measures.
PAGE 59
6802800U74-AP Chapter 2: General Safety CAUTION: Antenna design is the customers responsibility. All aspects of antenna design must comply with the relevant local regulations. CAUTION: Familiarize yourself with Man-Machine Interface (MMI) commands and their usage before performing procedures in this documentation. Improperly applying MMI commands can result in equipment damage.
PAGE 60
6802800U74-AP Chapter 2: General Safety In order to ensure optimal communication performance and compliance with applicable RF exposure limits, it is recommended that the antenna is installed outside the building hosting this equipment, on the roof or on a tower if at all possible.
PAGE 61
6802800U74-AP Chapter 2: General Safety WARNING: Burn hazard. The metal housing of the product may become extremely hot. Use caution when working around the equipment. Figure 5: Warning Label on Hot Modules WARNING: DC input voltage must be no higher than 60 VDC. This maximum voltage includes consideration of the battery charging "float voltage" associated with the intended supply system, regardless of the marked power rating of the equipment. Failure to follow this guideline may result in electric shock.
PAGE 62
6802800U74-AP Chapter 2: General Safety WARNING: Special precautions are required when handling batteries: 62 • To avoid spilling acid, do not tip batteries. • Battery acid can cause severe burns and blindness if it comes into contact with skin or eyes. Wash affected skin or eyes immediately with running water. Seek medical help immediately. • Jewelry should not be worn while working with batteries. • Installation personnel should wear necessary safety equipment when installing batteries.

6802800U74-AP Site Preparation Chapter 3 Site Preparation Before performing the MTS installation tasks, various considerations such as site planning or environmental requirements need to be taken into account. 3.1 Site Planning Proper planning helps to prevent potential on-site and off-site interference from other RF systems, and helps maximize system performance. To minimize the cabling lengths between RF equipment, plan site layouts.
PAGE 64
6802800U74-AP Chapter 3: Site Preparation • Suitability, space availability, and location of the existing cable tray or ladder rack between the equipment room and the antenna tower or the antenna system support structure. • Cable access route into the equipment room check • Type of tower and the type of structure on which the GPS antenna will be mounted 3.1.

The selection is done by configuring MTS using the BTS Service Software (TESS). The integrated GPS module can track both GPS and GLONASS satellites.
PAGE 136
6802800U74-AP Chapter 4: Hardware Installation greater than the recommended values (4 hours) may mean that the BTS is unable to maintain synchronization and can result in call failures and erratic network performance. If the GPS reference is not recovered in this time period, the MTS switches to the non-synchronized mode. If an MTS is started when no GPS reference is available, it operates in the non-synchronized mode. Non-synchronized mode will not have optimized hand-over performance.

A low PDOP value indicates a low error (higher accuracy) in the position calculated by the GPS receiver. A site with a large PDOP value may incur a delay when the site is first initialized.

6802800U74-AP Chapter 4: Hardware Installation 4.8.6 GPS Interference Avoidance You can employ the following two strategies to mitigate against jamming signals: • Determine a location where adequate GPS signals are available using a hand held receiver and move the Base station GPS antenna to this location. • Construct a shield (Cardboard Foil is adequate) to exclude the jamming signal. Locate the shield approximately 6 cm from the antenna body and connect it to an earth point. 4.9 X.

6802800U74-AP Chapter 7: Radio Frequency Distribution System Chapter 7 Radio Frequency Distribution System The Radio Frequency Distribution System (RFDS) distributes and manages the communications network frequencies and mitigates interference between multiple radios, allowing them to operate simultaneously. This results in improved radio reception performance across the frequency ranges where multiple transmitters are broadcasting. 7.

6802800U74-AP Chapter 7: Radio Frequency Distribution System 7.1.1 CAN Bus The intercommunication between the RFDS units (the Duplexers, Post Filters, and Cavity Combiners) and the Site Controller is carried out through the CAN Bus at 125 kB/second. The connectors for the CAN Bus are RJ45 connectors. The CAN Bus is terminated at each end, either by the Site Controller or by an RJ45 terminator. Each device is registered at the Site Controller (SC), which specifies the particular channel for each unit.
