What is the Specific Absorption Rate (SAR)?

What is the SAR?

The SAR (specific absorption rate) is an indicator of the amount of energy transported by radiofrequency waves absorbed by the mobile phone user.

The value SAR indicates the maximum exposure that the device may produce. The unit of SAR is watts per kilogram (W/kg). Within the European Union, the limit for a GSM is 2 W/kg.

SAR values are classified by category. These are indicated next to each of our devices offered for sale:

CATEGORY A: SAR values lower than 0.4 W / kg

CATEGORY B: SAR values equal to or higher than 0,4 W/kg but lower than 0,8 W/kg

CATEGORY C: SAR values equal to or higher than 0,8 W/kg but lower than 1,2 W/kg

CATEGORY D: regarding SAR values equal to or higher than 1,2 W/kg but lower than 1,6 W/kg

CATEGORY E: regarding SAR values equal to or higher than 1,6 W/kg but lower than or equal to 2 W/kg

Take care of your health - use your cell phone in moderation, prefer the use of a headset and choose a device with a weak SAR value.

What are the advantages of fibre optics?

The bandwidth potential of fibre optics is vastly superior to copper pairs. In contrast to ADSL, fibre optic signals do not deteriorate over distance (from the ADSL connection to the telephone exchange). Therefore, you can benefit from a very high bandwidth transmission, for outgoing and incoming data. Furthermore, fibre optics are not effected by electromagnetic interference. If you decide for a small bandwidth based on fibre optics today, you can easily upgrade your product to highest speed at any time.

How is the fibre optic installed in the building?

After signing your contract, a technician will come to install your fibre optic connection. This means he will install an optical termination device at the closest connection point in your home to connect your Wiizbox via Ethernet/LAN. If you do not have a proper in-house cabling, JOIN is able to support you. However, this support will be charged.
