Our expertise with distributed antenna systems (DAS) and indoor wireless communications help us address the complex issues associated with delivering multiple RF services in buildings. We ensure your wireless networks perform in desired coverage areas at a high level of service, with the required capacity for each location.
- Site Survey
- Building inspection including roof accessibility, firewalls and other RF obstructions
- AC power, grounding and environmental controls
- Identification and/or verification of cable pathways, head-end and remote equipment locations, and antenna placements
- Spectrum and propagation analyses
- RF measurements to understand the current environment and propagation characteristics, and compliance with received signal strength indicator (RSSI) requirements in the targeted service areas
- Detailed report of findings
- Detailed Radio Frequency Design
- Venue Analysis - Gathering all the required information about the venue including venue overview (capacity, area), floor plans, scope of services (operators and technologies) and required KPIs (signal & capacity requirements)
- Complete RF Design
- Building the requisite iBwave files - Importing the floor plans, creating the 3D model of the venue, studying the venue structure and defining the area of coverage
- Link budget calculations - DL power calculations from the BTS to the UE received signal and UL Noise calculations from the UE indicating the noise rise at the BTS
