Project Overview:

Challenges:

  • The remote location presented significant logistical difficulties in terms of site access and transportation of materials and equipment.
  • The 150,000 square foot building is constructed from 18” thick reinforced concrete walls effectively blocking what little donor signal that was available.
  • Limited existing cellular infrastructure meant that weak donor signal for all carriers would have to be intercepted.

Solution:

  • We utilize a mobile deployment model that allows us to travel, even to difficult-to-reach areas.
  • Lidar technology was used for site surveying, which minimized delays due to architectural designers and RF engineers.
  • Our team designed and installed a bi-directional amplifier system that uses a rooftop donor antenna to intercept and rebroadcast signal inside the building.

Results:

  • The project successfully extended 4G/5G coverage to more than 300 employees throughout the concrete and metal building.
  • Technology Design Group has installed 13 amplifier systems for this company since the first one in 2017.
  • The macro network expansion was completed with zero safety incidents and received commendations from owners and management.
