We supply and install Cel-Fi (Nextivity) smart repeaters — legal cell boosters that improve handset voice and data where outdoor signal exists but steel, decks and multi-floor buildings kill it indoors. Distinct from Peplink companion WAN: this fills dead zones for phones, not vessel internet.
Cell Boosters
Cel-Fi (Nextivity) smart repeaters for vessels and buildings — legal indoor cover, not an illegal booster.

What we supply
- Cel-Fi / Nextivity kits — GO, ROAM and Quatra-class smart repeaters
- Donor and service antennas — outdoor donor, indoor service coverage matched to decks, corridors or floors
- Documented install — survey, commission and handover — not a random illegal booster bolted to a rail
- Integration notes — when Peplink WAN already handles internet and Cel-Fi only restores handset cover
How we deliver
- Survey donor signal outdoors and map where handsets actually fail indoors or below decks
- Specify a Cel-Fi / Nextivity kit for the carrier and footprint — antennas included
- Install and commission so indoor coverage tracks the donor without interfering with the network
- Handover with coverage notes and who to call — separate from your Starlink or Peplink WAN record
Not Peplink cellular. Shipboard companion WAN (routers, MIMO, SIMs, SpeedFusion) lives under Marine Cellular. Cel-Fi restores handset cover inside the structure; it does not replace Starlink or bonded WAN.
When it fits
- Outdoor LTE/5G is usable on deck but handsets die below or inside steel structures
- Guest or crew phones need voice and data in cabins, corridors or multi-floor buildings
- You need a legal smart repeater — not an unlicensed consumer booster
Common questions
Is Cel-Fi legal?
Yes when it is a Cel-Fi / Nextivity smart repeater installed correctly for the network that owns the spectrum. Illegal consumer boosters are not the same product and we do not supply them.
Does Cel-Fi replace Starlink or Peplink?
No. Cel-Fi improves handset voice and data inside steel or multi-floor spaces where outdoor signal already exists. Starlink and Peplink deliver WAN for the vessel or site — different jobs.
Do you supply and install Cel-Fi?
We supply and install Cel-Fi / Nextivity kits as part of our connectivity work. Ask us for the right kit and install scope for your vessel or site.
