JB Technologies installs Westell Apex bi-directional amplifiers and DAS infrastructure for ERCES / public-safety radio coverage systems nationwide.
Westell is a public-safety DAS and bi-directional amplifier (BDA) manufacturer, whose Apex platform and signal-source equipment are used to close in-building radio coverage gaps for fire and police communications. JB Technologies is an authorized Westell installer, deploying the Apex platform and related DAS infrastructure as part of our nationwide ERCES practice — the code-driven emergency responder communication systems required under NFPA 1221, IFC 510, and local AHJ amendments. We confirm the local jurisdiction's ERCES requirements and BDA acceptance practices before specifying equipment, then design, install, and commission the BDA and antenna infrastructure through AHJ acceptance testing.
Office towers and mixed-use buildings where a BDA and antenna network are needed to meet the AHJ's minimum radio signal strength requirements.
Hospitals and outpatient buildings are a common venue for Westell Apex deployments given their multi-floor layouts and code-driven coverage requirements.
We deploy Westell where the local fire marshal or AHJ has an established practice of accepting the platform on ERCES submittals.

Westell is a manufacturer of public-safety bi-directional amplifiers (BDA) and DAS infrastructure. Its Apex platform and signal-source equipment are one of the equipment lines JB Technologies deploys for ERCES projects that need in-building radio coverage for fire and police communications. JBT is an authorized Westell installer as part of our nationwide ERCES practice.
JBT is a multi-platform ERCES installer. We also deploy ADRF and Nextivity Sentry BDA equipment, and select the manufacturer based on the building, the local AHJ's acceptance history for that platform, and the project's requirements.
No. ERCES / BDA systems amplify public-safety radio frequencies for fire and police, governed by NFPA 1221, IFC 510, and the local AHJ. That is separate from commercial cellular DAS (Nextivity CEL-FI, WilsonPro), which JBT also installs for carrier voice and data coverage — buildings sometimes need both.
Tell us about your building and jurisdiction and we will scope the right design, equipment, and AHJ acceptance plan.
