Construction of radio communication systems

Radio communications are used in situations where optical or metallic cable lines cannot be laid for technical or economic reasons. When constructing such systems, we provide complete services from pre-design research, design, calculation, up to the construction of antenna arrays.

We have already built wireless communication systems for our prominent customers Vodafone Czech Republic a.s., T-Mobile Czech Republic a.s., České Radiokomunikace a.s., UPC Česká republika s.r.o., Magnalink a.s., and GTS Czech s.r.o.

Detailed list of our activities in this field:

  • Local survey, designs, pre-design research
  • Steel structure design, safe access ways
  • Static and fire inspections, expert opinions
  • Design and calculation of radio communication systems, ČTÚ calculations
  • ČTÚ licensing proceedings, coverage maps
  • WiFi, WiMAX measurements and coverage maps
  • Installation works using climbing gear in hanging position
