The introduction of 5G completely changed cellular communication, making it faster, more reliable, and more efficient. However, with 5G and other cellular communication standards, come changes to mobile SAR and RF testing. Ensuring that next-gen devices are safe and reliable for users requires testing that changes and updates as quickly as technology does. Keep reading to learn more about these updates.

5G and Its Impact

5G is the fifth generation of wireless technology that updates communications in three ways: bigger channels, lower latency, and the ability to connect more devices simultaneously. 5G also opens up more airwaves to be used by carriers, improving connectivity.

In addition to this, 5G is also paving the way for faster development of other technologies like autonomous vehicles, virtual reality, and the Internet of Things.

This is because 5G offers 10 times more bandwidth than the previous generation due to its use of high-frequency waves in addition to low- and mid-band frequencies. High-frequency waves also provide gigabit-per-second speeds, making them particularly convenient now that high speeds are in demand. 

5G Mobile SAR & RF Testing

Higher frequencies and power levels used by 5G also increase the level of exposure to radiofrequency (RF) energy. In addition to increased RF energy exposure, 5G has also introduced features like beamforming, Massive MIMO, and millimeter-wave frequencies, all of which complicate testing protocols for RF exposure.

RF testing is also crucial to ensure that 5G devices operate without causing interference within their designated frequency bands, maintaining their performance and reliability.

Mobile SAR Requirements for 5G Devices

Three frequency bands make up 5G, and each has different implications for SAR and RF testing. The low band covers frequencies less than 1GHz and can cover greater distances than high frequencies but is not as fast. The mid band ranges from 1GHz to 6GHz and balances speed and distance compared to the low and high bands. The high band ranges from 24GHz-40GHz and offers the highest speeds of all three bands with the least coverage. The use of these three frequency bands provides better coverage and reliability.

Considerations for 5G Devices

When it comes to considerations for different 5G devices, a variety of details need to be taken into account depending on how a device is used or worn.

These considerations include:

• Proximity: 5G devices are typically used close to the body, requiring SAR testing to ensure the RF energy emitted by these devices is within a safe limit. 

• Performance: Mobile SAR testing for these devices is required to verify that they perform well across multiple frequency bands.

• Skin contact: Wearables like smartwatches make constant contact with skin while in use. These devices have to be tested in variable usage conditions, like while in motion.

• High Power for Long Range: Fixed Wireless Access (FWA) devices provide internet access and require testing for higher power output to show that they meet both RF exposure limits and network performance standards over long distances.
• Harsh Environments: 5G devices used in industrial settings need to perform reliably in harsh conditions, requiring ruggedness and RF testing for interference in dense network environments.
