Cellular Radiation Overview

Mobile phones allow communication from any location via a network of base stations (cellular antennas). Information is transmitted from the mobile phone to the base station and vice versa via high-frequency electromagnetic fields. 

The intensity of cellular (non-ionizing) radiation exposure during a call depends on various factors:

• A mobile phone emits less radiation when connection quality is good than when it is poor.
  • Connection quality is, for example, better outdoors than in a building or areas with connectivity interferences (basement, elevator, car, etc)
  • Connectivity improves with proximity to a cellular base station
  • Connectivity can be reduced by phone usage such as antenna orientation (if the phone is held vertically or horizontally), travel speed, etc
• The proportion of radiation absorbed by the human body when making a call varies according to:
  • The model of mobile phone, conveyed by the Specific Absorption Rate (SAR). Maximum SAR  levels are set by governmental regulating agencies in many countries (e.g. the FCC in the US)
  • The antenna’s proximity from the body

tawkon’s RRI™ (Real-time Radiation Indication) Technology

Leveraging various smart-phone capabilities such as the built-in Bluetooth, motion and proximity sensors, GPS and compass, tawkon's RRI™ patent pending technology alerts the user when radiation level cross a predefined threshold and provides simple, non-intrusive suggestions to reduce exposure to radiation.

Mobile phone users are not exposed to high levels of radiation all the time. tawkon is the only application that recognizes when radiation exposure has increased, and provide specific suggestions to minimize exposure to mobile phone radiation based on the user’s real time environmental and usage parameters.

tawkon therefore gives users the freedom to continue using their mobile phone as usual, while providing all the required information to take precautionary action to minimize exposure to mobile phone radiation just as needed.

tRi™ (tawkon Radiation Indication) units denote the absorbed cellular radiation by the user while incorporating three key parameters:

• Phone SAR – different for each phone model (W/Kg)
• Dynamic environmental conditions – rural versus urban area, mobility, distance from Cellular Base Station (BTS/Node-B), terrain, etc
• Personal phone usage – the way the user holds the phone, distance from the user’s head/body, etc.

The patent-pending RF component of the tawkon technology was developed and tested by and in collaboration with In4Tel Ltd, a tawkon strategic partner.
