Altan began by reviewing the existing circuit design, component selection, printed circuit board layouts and mechanical construction of both headband and base station.
Testing indicated poor reception of the base station transceiver and inferior output of the headband transmitter.
Headband operation was tuned and optimized, yielding immediate improvements that Zeo could measure.
Next, Altan staff measured and documented the existing system performance, then defined the necessary changes to component selection and printed circuit board layout that would provide significant improvements.
To help Zeo understand the expected performance of the system, Altan developed a link budget for the application to show that Zeo’s performance targets could be met.
Altan simulated key portions of the updated solution to validate proposed changes.
Then, Altan staff guided the Zeo team through the required changes, including:
- component selection
- modifications associated with correct shielding
- grounding and antenna circuit methods
- providing detailed instructions for each change
Once the changes were implemented, Altan tested and tuned the updated headband and base station units, then conducted field tests to validate the changes. The improvements were dramatic.
