3.2 Infrastructure Preparation
The following installation rules are based on the assumption that the site survey and installation planning (including power
requirements) have been completed.
3.2.1 Site Considerations
• The distance between the MRU service antenna and the coverage area should correspond to line of sight (LoS)
requirements for maximum coverage area.
• The maximum fiber path loss is 5 dB.
• The system delay of the optical system must be taken into consideration when there are neighboring BTS sites overlapping
in coverage.
