What is SAR, OTA, and EMC?

There are many factors when talking about mobile radiation, and information to be aware of when choosing a cell phone. Are you also confused about the different abbreviations and what they mean? Read about them here.

SAR

SAR stands for "Specific Absorption Rate" and is the unit of measurement that indicates the amount of RF power (radio frequency power) that is absorbed into the body when using a mobile phone. The term thus covers the radiation that a mobile emits when it is connected to a network, via WiFi or 4G / 5G (mobile network).

SAR values on mobile phones are something that everyone should research further before buying a phone. It has a big impact on many things on your mobile, from mobile radiation and antenna quality to performance and battery life. Men's sperm quality can also be affected.

The quality of the antenna has an impact on the overall experience of the mobile. Poor antenna quality means reduced battery life, user interface speed, call quality during calls, and Internet connection.

The SAR value is thus assessed on the basis of the antenna quality and tells about the connection between high SAR value and low antenna quality.

OTA

OTA stands for "Over-the-Air" and is a method of testing the wireless performance and reliability of wireless devices via the antenna. The performance of the antenna must be examined to ensure the quality of the wireless connection in any situation.

Why is OTA important? Because no one likes bad connections, and this can be avoided by verifying the wireless performance with an OTA test. As a consumer, it is important for the overall experience that you can count on the quality of the connection, both during conversation and use of apps. And also, when you want wireless equipment connected such as headphones or speakers.

If the antenna and the connection are not good enough, they will send the signal more frequently and with more power, which affects the battery consumption and the mobile radiation.

EMC

EMC is an abbreviation for "Electromagnetic Compatibility" and is the ability of a system to function properly in an environment without affecting any other system or itself.

EMC thus plays an important role in ensuring that electrical devices and equipment not only function perfectly themselves, but also in harmony with each other. Legislation requires that certain standards be met; EMC is also a key quality feature for product manufacturers.
