2 Installation Preparations
This chapter describes the preparations for MST200 installation, including preparation of installation
tools,selection of installation sites and etc.
2.1 Preparing Installation Tools
When installing MST200, you may need the following tools. You shall select the tools according to the actual
situation.
Table 2-1 Installation tools list
Type Tools
General tools
Screwdriver, adjustable spanner, vice, safety belt, hard hat, power
board (220 VAC or as required by local regulation), POE power
injector, crimping pliers, electric soldering iron, welding wire, PVC
insulation tape, adhesive insulation tape, strap, insulation tools
2.2 Examining the Installation Site
1. The site should be located within at least a 60% range of the 1st fresnel zone without obstacles to
provide LOS transmission, increase coverage capacity, and minimize the number of necessary
sites.
2. If no LOS secured, area in NLOS area could be covered as well, but the distance of coverage and
area of coverage are decreased; more sites are needed to provide coverage for same area than in
the LOS scenario.
3. Interference must be considered in site selection. New site should avoid known interference, unless
the interference is controllable.
4. Keep the MST200 away from places that are susceptible to high temperature, dust, harmful gas,
inflammable, explosive, electromagnetic interference (high power radar, radio station and
transformer), unstable voltage, heavy vibration, or loud noise. In engineering design, the site should
be selected according to the network planning and technical requirements of communications
equipment, as well as the considerations such as climate, hydrology, geology, earthquake, electric
power, and transportation.
