Integrating Multiple Radios in a Compact Product

Overview

Optimising coexistence between multiple wireless technologies within a constrained enclosure.

Technologies

RF design | Antenna systems | Wi-Fi | Bluetooth | Cellular

Define the Problem

A compact product required simultaneous operation of Wi-Fi, Bluetooth and cellular radios within a restricted mechanical envelope.

Diagnose the Root Cause

Investigation identified antenna coupling and insufficient isolation between radio systems, degrading communication performance.

Key engineering challenges included:

• Limited enclosure space

• Multiple antenna systems

• RF coexistence requirements

• Mechanical constraints

Deliver the Solution

We redesigned antenna placement and implemented isolation improvements to minimise interaction between radio systems.

Key Outcomes

• Reliable simultaneous radio operation

• Improved wireless performance

• Reduced RF interference

• Maintained compact product size
