Before a 5G CPE can be sold, imported or switched on, it must clear a layer of radio-frequency and environmental rules that are easy to overlook in the rush to evaluate throughput and cost. These are not the same as carrier certification or cybersecurity conformity—they are the safety, exposure and materials requirements that determine whether a device can legally enter a market at all. For an operator, distributor or importer, understanding EMF, SAR and RoHS/REACH/WEEE compliance is the difference between a smooth rollout and a shipment held at the border.
EMF exposure limits: indoor vs outdoor CPE
Every radio transmitter must comply with electromagnetic field exposure limits, and the applicable limit depends on how close people get to the device. Fixed CPE and routers are evaluated against maximum permissible exposure (MPE) limits at a defined separation distance—typically 20 cm for indoor units—based on standards such as ICNIRP 2020 in Europe and the FCC’s limits in the United States. Outdoor CPE and higher-gain units must demonstrate compliance at their intended installation distance. Buyers should confirm the device has EMF test reports for the markets where it will be deployed, and that installation guidance states the required separation distance.
SAR: the near-body case for MiFi and hotspots
Portable devices used close to the body—5G MiFi and pocket hotspots—are instead assessed by specific absorption rate (SAR), which measures how much RF energy the body absorbs. SAR limits are stringent and tested in specific near-body configurations. A hotspot that passes MPE-style testing may still fail SAR testing if it is meant to be carried in a pocket or worn. Buyers sourcing MiFi should explicitly request SAR reports and the tested body-worn distances, and confirm the device carries the appropriate conformity marking for each target market.
Environmental compliance: RoHS, REACH and WEEE
Environmental rules govern what a device is made of and what happens to it at end of life. RoHS restricts hazardous substances such as lead, mercury and cadmium in electronics; REACH controls substances of very high concern and, in the EU, requires SCIP database notifications for articles containing them. WEEE requires producers to register and finance take-back and recycling of electronic waste, with obligations that vary by country. For an importer, these rules determine both market access and ongoing administrative duties—and they increasingly appear as explicit clauses in operator tenders.
Eco-design and energy efficiency
Energy is the newest front in CPE compliance. The EU’s eco-design framework for broadband equipment sets standby and connected power limits, while energy labels and efficiency programmes push devices toward lower idle draw. These rules align with the green-procurement clauses operators are adding to RFPs, and they translate directly into the total cost of ownership for a fleet that runs 24/7. Buyers should verify standby power figures against the applicable thresholds, not just against the vendor’s own claims.
Conformity documentation and marking
- Declaration of Conformity and full technical file covering EMF/MPE, SAR (for portable devices) and environmental directives
- Markings: CE and, where required, UKCA, with correct notified-body involvement if applicable
- RoHS / REACH / WEEE: substance declarations, SCIP registration and producer take-back arrangements
- Battery compliance: EU battery regulation and transport (UN 38.3) documentation for devices with integrated cells
- Eco-design evidence: standby and connected power measurements against the applicable limits
Compliance documentation is not paperwork for its own sake; it is the proof that a device can be legally deployed and resold in every market an operator serves. By making EMF, SAR and environmental conformity an explicit part of CPE selection, buyers avoid border delays, legal exposure and costly retrofits—and build a fleet that is as defensible on paper as it is capable in the field.
