Technology is the longevity domain where the evidence is mixed, the discourse is loud, and the cost of being precautionary is genuinely small. The framework treats it accordingly: cheap interventions, scoped to the rooms where the body is most vulnerable, no claims beyond what the literature supports.
What technology actually is, in a residence
Three exposure types matter:
- Radiofrequency: Wi-Fi, mobile, DECT cordless phones, smart-home wireless, smart meters. The exposure that gets the headlines.
- Low-frequency: 50/60 Hz wiring, transformers, motors. The exposure that lives inside walls and is least often considered.
- Dirty electricity: high-frequency transients on the building wiring, produced by switching power supplies. The exposure most homes don’t realise they have.
The MAVI 129 framework covers all three. The remote Blueprint does not measure any of them: it reads the public register of masts around your address and takes your answer about what sits by your bed.
The thresholds that matter
The honest position: regulatory thresholds are based on thermal effects, and the question of non-thermal effects is unresolved. The framework adopts the precautionary thresholds proposed by the EU Council Resolution 1815 and by Building Biology guidelines for sleeping zones:
- Sleeping bedroom RF: target below 10 µW/m² (Building Biology “no concern”).
- Wi-Fi router placement: at least 2 m from the head of the bed; 3 m or more preferable.
- Smart-meter location: not on the wall behind a sleeping head.
- Mobile-phone charging: not on the bedside table; not under the pillow.
- Dirty electricity: filterable at the panel; an electrician can test the circuits that feed the bedroom.
Source-distance is the cleanest variable. RF intensity falls with the square of distance; doubling distance quarters the exposure.
Where the design decisions actually live
For most residential projects, the technology outcome is set by four decisions:
Router and access-point placement. Centralised, away from bedrooms, scheduled to dim outside use hours. Wired backhaul to access points reduces the number of high-power radios on the property.
Bedroom sanctuary. No router, no smart-meter, no DECT phone, no charging device within 2 m of the head of the bed. Wired ethernet for any sleep-area device that benefits from connectivity. This is the single non-negotiable rule of the domain.
Wiring and dirty-electricity filtering. Switching-load segregation (LED drivers, USB chargers, variable-speed motors on dedicated circuits). Panel-level filters on circuits feeding sleeping zones if measurement warrants.
Smart-home topology. Where smart-home systems are specified, prefer wired (PoE, KNX, BACnet) over wireless mesh in habitable rooms. Where wireless is required, choose lower-power protocols (Zigbee, Z-Wave) over Wi-Fi for low-bandwidth applications.
What “technology” looks like in a MAVI Blueprint
A residence’s Technology score is built from the public register of mobile masts around the address and your answer about what sits by your bed at night. The Blueprint reads your home remotely, so nothing is measured inside it.
The output is a 0 to 100 sub-score and a priority intervention list. For most residences, the highest-leverage interventions are bedroom-sanctuary specification and router placement.
The single thing to do today
Stand at the head of your bed and look around. Count the things that emit RF: mobile phone, Wi-Fi router, smart speaker, smart watch, baby monitor, smart-meter on the other side of the wall. Move the ones that don’t need to be there. The MAVI Blueprint reads the public register of masts around your address, takes your answer about what sits by your bed, and ranks the changes worth making.
