GO G41, GO G43, GO G51 — single-carrier boosters for homes, small offices, and vehicles. Up to 100 dB system gain.
Smart, network-managed boosters for medium commercial spaces. Wi-Fi configurable; remote monitoring via CEL-FI WAVE.
Active DAS for enterprise — hospitals, hotels, warehouses, multi-tenant buildings. Network Unit + Coverage Units over Cat-6A or fiber.
LPDA donor antennas, omni and panel server antennas, splitters, couplers, cabling kits — everything needed for a CEL-FI install.
Yes. JB Technologies is a Nextivity PRO Partner and authorized CEL-FI reseller. All units we sell are sourced direct from Nextivity, carry the full manufacturer warranty, and are eligible for CEL-FI WAVE remote management.
Both. The GO and PRO Series are designed for end-user installation with a donor antenna and a server antenna. For QUATRA EVO active DAS or any multi-floor commercial install, we recommend a JBT professional install: site survey, RF design in iBwave, BDA/QUATRA commissioning, and after-action commissioning report. Atlanta-metro is on-site; the rest of the Southeast US is on-site by quote.
A CEL-FI QUATRA EVO Network Unit lists in the low-five-figure range; each Coverage Unit adds incrementally. A typical small commercial QUATRA build (1 NU + 2 CUs + antennas + cabling, no install labor) lands around $12K–$20K. For pricing on a specific building, request a quote and we'll size it from your floor plate and carrier list.
CEL-FI GO is a single-band-pair, single-carrier consumer/SMB booster — best for homes and small offices. CEL-FI PRO is the smart, Wi-Fi-managed version of GO with remote monitoring. CEL-FI QUATRA is a true active distributed antenna system: one Network Unit feeds multiple Coverage Units over Cat-6A or fiber to deliver carrier-class cellular across enterprise floor plates without RF leakage between zones.
Yes. CEL-FI is carrier-approved on AT&T, Verizon, T-Mobile/Sprint, FirstNet, and most regional carriers in the US. CEL-FI GO is single-carrier per unit (the carrier is selected during commissioning); CEL-FI PRO and QUATRA EVO are multi-carrier and multi-band on a single deployment.
CEL-FI boosts commercial cellular bands (700–2600 MHz LTE/5G) for civilian phones; an ERCES BDA boosts public-safety bands (700/800 MHz, VHF, UHF) for first-responder radios on the local FCC license. They are separate systems with separate code requirements. JBT sells the Nextivity SHIELD ERCES BDA for code-required public-safety coverage and CEL-FI for commercial cellular — see our ERCES service page for the public-safety side.
