What makes
in-building comms hard
Buildings keep getting denser and more enclosed, and the demands on communication inside them keep rising. High connection density and constant traffic are more than a conventional system can carry.
Thick walls, structural cores and below-grade levels block signal and leave pockets nothing can reach.
Several systems coexist in a dense building and interfere with each other, degrading call quality for all of them.
Capacity runs out under constant use, and calls queue or fail exactly when they matter most.
Multiple tenants and multiple teams in parallel make maintenance and day-to-day management costly to run.
Zoned coverage,
seamless roaming
DistriNET divides the building into independent communication zones. Each one carries its own signal from the base station, with its own antennas and optical remote unit (ORU)s, covering levels above and below grade. People move freely; the system hands over and roams behind the scenes with nothing to switch and nothing to reconnect.
A slim ceiling antenna
that does more than cover
The indoor smart antenna is slim enough to sit flush against a white ceiling tile or hide above it entirely. Powered over the feeder from the optical remote unit (ORU), it adds coverage self-checking and iBeacon on top of the radio path — opening up positioning as well as communication inside the building.
Shifts in signal strength reveal a change in coverage distance; when coverage falls short the antenna flags it, including by LED indication.
Bluetooth Low Energy with integrated iBeacon supports indoor wayfinding, location awareness and related applications.
Several tenants, one communications infrastructure
A large mixed-use development holds very different operations under one roof. DistriNET gives each of them a dedicated communication zone, while car parks, arrival halls and plant rooms are shared across all users — independent where it matters, common where it pays.
Office towers, retail and other standalone operations each hold their own signal zone and their own talk groups, matched to how that business actually works.
Basement car parks, plant rooms and arrival halls are designated shared zones — several users on one communications system, resources allocated on demand.
DMR, Wi-Fi and 4G converged —
one system, one radio
The control centre, engineering and security run on the DMR private network for guaranteed access. Housekeeping rides the in-building Wi-Fi. Off-site roles such as airport greeters join the same network over 4G. Different posts, different bearers, one communications system.
Duty dispatch and overall command, where reachability has to be absolute.
Patrol and incident response stay on the private network for guaranteed access.
Guest floors ride the in-building Wi-Fi at no data cost.
Roles away from the property join the same network over 4G.
DMR private, Wi-Fi and 4G all stay live in the background. As the user moves between areas the radio selects the network itself — no channel changes, no second device, one issue covering every role in the building.
Bring the responder network
into the enclosed spaces
Fire stairs and basement car parks are exactly where public-safety signal usually fails. DistriNET carries the responder band into those areas as part of the same distributed system, so crews stay in contact at the moment it counts.
Online maintenance, faster service response
DistriNET pairs with the NetFlex platform to monitor the system in real time — signal quality, device health and coverage all in one view. Engineers diagnose, reconfigure and clear faults remotely, so a service call rarely starts with a site visit.
From system health to where people are and whether the job was closed out — one back office covers the whole building.
System health score, active alarms and where people are — the duty manager sees the state of the building on the first screen.
From a communication tool
to a work tool
Commercial radios keep getting smaller and smarter: a clean form factor, clear audio and noise suppression that keep conversation effortless, plus integration with dispatch consoles and management software. Because DistriNET puts signal close by, the radio transmits at lower power and lasts longer — and stays bound to a named person, so work can be tracked and managed.
One-handed operation, easy to carry, quick to pair with a Bluetooth headset.
Connects to dispatch consoles and management software to simplify workflow and assignment.
Low transmit power and efficient power management keep it online through a full shift.
Voice records, location and battery state tie back to a named user, so work stays trackable.
Charging and storage, under management
A central charging cabinet replaces chargers scattered across back-of-house. Paired with NetFlex, charging becomes orderly and monitored — a fully charged radio waiting for whoever comes on shift next.
Multiple chargers stacked into one cabinet for central storage and collection — suited to large facilities and security teams.
Six bays, an independent management chip per bay, and an Ethernet link reporting battery state back to NetFlex.

Smart building radio coverage FAQ
The questions we hear most often on selection, certification and delivery.
Didn’t find your question? Ask an engineer →Concrete cores, steel and low-E glass block RF. A distributed antenna system fed by optical fiber repeaters places low-power antennas inside these spaces, so coverage no longer depends on a rooftop or outdoor site.
Yes. DistriNET combines several bands and channels onto one antenna network through combiners, so each team keeps its own channels while the building installs only one set of antennas and cabling.
Each zone is served by its own ORU on fiber. New zones are added by connecting another ORU to the existing OMU, without re-engineering zones already in service.
Smart antennas and repeaters report status to the network management system and NetFlex, so faults are flagged by location before users notice dead spots.
