Radio Coverage Storage Facility Improved with RFI MiniSystem Combiner

RFI minisystem washington state case study image

Quick Facts

  • A large-scale cold storage facility in Washington State required reliable radio coverage for three radio channels, across two sites.
  • With a combined area size of 5 million cubic feet, worker's safety, productivity, and efficiency were key project concerns.
  • The compact form factor and ease of installation made the RFI MiniSystem Combiner the perfect plug-and-play coverage solution.
  • Exceeding coverage requirements, the MiniSystem Combiner has received great feedback from the end-user.

Challenge

A large-scale cold storage facility in Washington State required reliable radio coverage. The building structure was complex and had a high metal content meaning, the system had to be carefully designed to provide coverage in critical areas.

Despite the large size of the facility, the available space for communications was limited and the solution had to fit inside the existing rack space. With a tight budget, the deployment operation costs also had to be kept to a minimum, and the solution needed to be easy to install, operate and maintain.

Solution

After thoughtful consideration and comparing different proposals, RFI’s MiniSystem Combiner was selected as the multicoupling solution to provide coverage for three radio channels at the facility.

The MiniSystem provided the customer with a very compact, self-sufficient and cost-effective multicoupling solution. It helped our partner, Day Wireless Systems, to use the existing rack space and install equipment in a short span of time.

Results 

The MiniSystem was delivered to the customer and deployed within the expected timeframes. The solution exceeded coverage requirements to provide reliable communications for all areas of the facility increasing productivity, efficiency and workers safety. Project costs were minimised and the MiniSystem Combiner has received great feedback from the end-user.

About MiniSystem Combiner

RFI MiniSystem Combiner is an innovative solution that offers the complete transmit and receive multicoupling and filtering for 1 to 4 RF channels in a single compact enclosure. It simplifies the design, procurement and installation.

MiniSystem Transmitter combiner uses dual-stage isolators and hybrid combining techniques to provide excellent Tx-Tx isolation and to minimise inter-modulation (IM) impacts. The Rx system uses an ultra-low noise preamplifier with user-selectable gain and excellent 3OIP performance, with a multi-way output divider to ensure optimum system receive sensitivity is available. Depending on the model, the integral high-quality bandpass filtering or duplexer provides high Rx selectivity and Tx-Rx system isolation performance. MiniSystems are available in sub-bands covering VHF, UHF and 7/8/900MHz frequency ranges.
