Most products combine several radios. A smart meter may need NB-IoT, LoRa, wireless M-Bus and NFC; a wearable may need Bluetooth, GNSS and wireless charging. We look at them together: antennas, coexistence, power and EMC.
What we do
RF & antenna design
Antennas from kHz to GHz, designed with the whole product, because the board, the battery and the enclosure radiate too.
Wireless connectivity
NFC, Bluetooth LE, Wi-Fi, LoRa, wireless M-Bus, NB-IoT, LTE-M and GNSS, chosen and integrated as one system.
Wireless power
Wireless charging and energy harvesting for small sensors, wearables and medical devices.
Low-power sensor systems
Complete sensor products, from hardware and firmware to mechanics and the cloud link, that run for years without maintenance.
EMC & certification
Design reviews, pre-compliance tests and debugging, so you pass CE/RED and FCC with fewer surprises.
Measurement & research
Characterization, field-failure debugging and targeted research when you need data before a decision.
Where our work runs: smart meters and utilities, smart buildings and locks, gas detectors, medical and wearable devices, agriculture and storage monitoring, industrial IoT and consumer electronics.
We design to three budgets
Every wireless design has a power budget and a link budget. We add a third.
Power budget
How much energy the device needs. We aim for years on one battery, or no battery at all.
Measured in microamps and milliwatt-hours.
Link budget
How reliably the signal gets through walls, metal and bodies. We aim for a margin large enough that nobody has to troubleshoot the link.
Measured in decibels.
Attention budget
What a device asks of people after a first minute of understanding. The goal isn't zero attention: it's attention well spent, on what the device is for, not on menus and notifications.
Counted in interruptions and minutes per day.
Selected work
Most of our client work is confidential. We publish it anonymized, and keep the engineering numbers.
