Radiation is usually classified into two types, based on its frequency: Ionizing radiation and non-ionizing radiation. Body heat is radiation, as is the light reaching our eyes. However, the evidence indicates that there is no foundation for these concerns.įirst, it should be understood that radiation is the emission of energy from any type of source. The needed addition of antennas and the transition to higher frequencies has ignited concerns regarding potential health dangers to the users. Therefore, the 5G network requires a wider distribution of cellular antennas, with smaller and denser cells. The explanation here is that as the higher the frequency, the higher the absorption and dispersion (attenuation) of the radiation, thus the carried signal fades as the distance increases. Higher frequencies limit communication to shorter distances (hundreds of meters) compared with existing network radio waves, which utilize lower frequencies that enable communication up to several kilometers. Higher frequencies enable the transfer of more data, but could also cause certain disruptions in communications, for example, when the user is inside a building made of concrete. The radio waves used by the new network are characterized by a higher frequency (the number of occurrences per second) than existing networks, and can reach up to 28 gigahertz. Latency is measured in milliseconds (thousandths of a second), and in the new 5G network, the latency target is a few milliseconds – a 5-10-fold improvement over the fourth generation. Network latency is the time it takes for information to travel from one end of the communication line to the other, or from our cellular phone to the phone of the person we are communicating with. It does this by switching to the appropriate communication frequency, as adjacent cells use different frequencies to avoid communication disruptions. When we’re on the move while being connected to the cellular network, travelling from one cell to another, the cellular network can transfer the communication to the next cell we have entered. In turn, the router transfers the data through the landline telephone network to the appropriate destination, or, if the destination is another cellular device, to the antenna through which it receives. In a nutshell, cellular phones transmit data to an antenna in range, and the antenna transmits the data to the network’s main router. This area is termed a “cell ” hence, cellular networks. Each antenna can transmit and receive signals, or conduct other kinds of communication, with cellular devices in a small area around it. Cellular phones do not communicate with one another directly, but through a widespread network of antennas. Is the new network indeed dangerous?Ī cellular radio network enables cellular phones to receive and transmit radio waves. But some of the articles also warn against possible harmful health effects. Recent reviews explain that 5G will provide information to more users at any given time, enable faster data transfer speed, and shorten network latency in data transfer. The fifth-generation cellular network, or 5G, is a digital cellular network that relies on a new technology, due to become operational in Israel and the rest of the world in the near future.
