Output keeps growing; the network keeps catching up
On a semiconductor, display, precision engineering or pharmaceutical floor, communications has to satisfy four constraints at once: cleanliness class, electromagnetic compatibility, continuous production and phased construction.
Capacity grows in phases, and the network is rebuilt round after round, with core equipment added again each time.
Precision equipment carries explicit electromagnetic limits, and a conventional antenna’s power affects the production environment.
The electromagnetic environment around large tools and specialty gas rooms is severe, affecting both transmit and receive.
The customer already has a radio brand its people know, and compatibility and interference between old and new is a lasting problem.
A break in communication is lost output, so the system has to be maintained and extended without stopping the line.
People move quickly across a very large site, so voice and data access has to hand over seamlessly.
Built zone by zone, scaled with output
One base station distributes the signal centrally, and each building or hall becomes an independent zone over fibre. Zones do not interfere with one another, a new plant area can be designed as a module and cut over in one go, and construction never disturbs what is already running.
Every production area and every critical post accounted for
Antennas are designed with 25% overlapping coverage, so moving between them causes neither interference nor a disruptive handover; around critical production equipment and plant rooms, both voice and data stay available.
Antenna radiated power is held under the electromagnetic limits set for precision production equipment, while still ensuring radios communicate clearly in heavy-interference areas.
Using antennas with business-interaction capability at critical points means the antenna network carries more than speech — it supports the data exchange the operation runs on.
The cable carrying the signal also powers the antenna, so no separate supply has to be run. In an antenna network already installed, any position can be upgraded to a newer antenna with more capability.
Field data that makes coordination faster
At production scale, coordination depends increasingly on data being timely and complete. On top of the coverage network, the operations platform turns both coordination performance and system stability into data you can see and search.
Core base station and zone core equipment are monitored online, so faults are found and cleared several times faster — which is what 24-hour operation requires.
MA12 antennas report the position of radio-carrying staff back to the platform, and the indoor map shows distribution and trends across the site and inside buildings.
Scheduled rounds are confirmed automatically as a radio passes an antenna, with nothing for the worker to operate; deviations and site conditions can be acted on immediately.
Voice and condition data in volume stay on the local platform, shared over the internal network.
An API feeds the data continuously into the enterprise business or control platform, so what the radios capture goes further.
Memory-chip manufacturing base, Wuhan
A fast-rising Chinese memory manufacturer, holding roughly 4% of the global NAND market in 2021 and an estimated 7% in 2022. The site runs trunked base stations of the customer's existing brand alongside the Evertac DistriNET coverage system.
The customer keeps the radio brand its people know, so the design has to avoid compatibility problems introduced by third-party equipment. The site is divided into dozens of independent communication zones to limit accumulated interference.
Semiconductor production carries strict environmental and health guidance. The FAB area uses tighter radiated-power control; specialty gas rooms and areas near heavy interference use explosion-proof antennas and transport equipment.
Continuous production tests people, equipment and system alike. Modular zoning shrinks the reach of any fault and makes handling it calmer; people moving fast still hand over seamlessly.
Recommended product mix
One base station distributes site-wide, same channels and same quality.
Suppresses intermodulation and accepts third-party base stations.
Cable power, field-strength sensing and an iBeacon.
Bluetooth positioning and task cards, so a round leaves a trace.
A consistent system
costs less to live with
Base station, combining platform, fibre transport and antennas, radios and the operations platform all come from one supplier, giving system consistency above 90%. Products that work together fail less over the long run, and an expansion does not mean rebuilding.

Factory and fab coverage FAQ
The questions we hear most often on selection, certification and delivery.
Didn’t find your question? Ask an engineer →One base station distributes signal over fiber to each building and production hall. Every zone gets the same capacity and voice quality, and zones do not interfere with each other.
Yes. New zones are designed as modules and connected to the existing fiber backbone in a single cut-over, so operating areas stay on air during construction.
Hazardous storage areas use dedicated explosion-proof repeaters and antennas, managed as part of the same system.
Yes. Low-power antennas and EMC-aware design are used in cleanroom and sub-fab areas; references include a memory-chip manufacturing base in Wuhan and a foundry fab in Singapore.
