Centers of Excellence · Communications & Wireless

Connecting components, devices, products and systems.

ATRI engineers communications across the layers that make modern products connected — from board-level interfaces and industrial communications to RF, wireless networks and edge-to-cloud connectivity.

Our engineering spans communication electronics, RF and antennas, embedded firmware, drivers, wired and wireless protocols, networking, software and physical product integration — allowing ATRI to develop the communication system as an integrated part of the product.

From Requirement to Working Communication System
ATRI engineers the complete communication system — not just a radio or a protocol.
01
Define

Range, bandwidth, latency, power, mobility, environment, device density, physical constraints and regulatory considerations.

02
Architect

Select communication technologies, network architecture, RF approach, antennas, processors, modules, interfaces and topology.

03
Engineer

Design and integrate communication electronics, RF systems, antennas, readers, interfaces and supporting hardware.

04
Develop

Create firmware, drivers, communication stacks, protocols, device-control software and application interfaces.

05
Integrate

Integrate electronics, antennas and communications into the physical product considering enclosure geometry, materials, component placement, power, thermal behavior and RF performance.

06
Validate & Productize

Bring up/debug the system, evaluate connectivity and RF performance, optimize communication behavior, support pre-compliance and prepare for production.

Communication Performance Is a System Problem
Electronics + RF + firmware + software + packaging have to work together.

Wireless performance cannot be separated from PCB/electronics, antenna, firmware, power and physical packaging — a strong radio on a poorly placed antenna, or firmware that ignores power budget, will underperform regardless of the parts used.

RFID / Identification System
Tags/transponders + readers + antennas + embedded electronics + firmware + software + application integration
Connected IoT Device
Sensors + electronics + wireless connectivity + antenna + firmware + device management + edge/cloud connectivity
Location-Aware System
GPS/GNSS/UWB + antennas + embedded processing + firmware + communications + application integration
Wireless Industrial Controller
Control electronics + communications + antenna + embedded controller + firmware + industrial protocols + physical packaging
Connected Edge System
Devices/sensors + wired/wireless communications + edge compute + data movement + software + cloud/application integration

These are representative engineering combinations, not named customer projects.

RF Engineering Inside the Real Product
The antenna doesn't operate in isolation.

Antenna and RF performance can be affected by enclosure geometry, materials, PCB layout and placement, batteries, displays, nearby electronics, mechanical structures and the operating environment.

ATRI brings together RF, electronics, embedded and mechanical engineering so communications performance can be engineered as part of the complete product — from antenna placement and electronics integration through firmware, enclosure packaging and system validation.

Communications for Intelligent & Agentic Products
Connecting intelligence across the physical and digital world.

Connected intelligent products exchange information with sensors, equipment, devices, people, edge systems and cloud services:

Sense remotely
receive information from distributed devices and sensors
Exchange
communicate between products, equipment and systems
Locate
identify, track and determine device/asset position
Connect
link physical products, edge systems and cloud applications
Coordinate
share state, events and instructions
Act
deliver commands/actions to connected products and equipment
Report
communicate status, events, results and system health

ATRI engineers the communication pathways that allow intelligent products to exchange information, coordinate and act as connected systems.
