Difference between 3g and 4g

4G Networks

4G, or the current standard of cellular networks, was released in the late 2000s and is 500 times faster than 3G. It has been able to support high-definition mobile TV, video conferencing and much more.

Signal strength in dBm on 3G does not work the same way as on 4G/LTE. The numbers are basically a bit skewed such that the quality of voice and data transmission is better on 4G due to its efficiency and therefore the signal can be worse but the service would fare comparatively better on 4G than on 3G.

LTE, sometimes known as 4G LTE, is a type of 4G technology. Short for “Long Term Evolution”, it’s slower than “true” 4G, but significantly faster than 3G, which originally had data rates measured in kilobits per second, rather than megabits per second.

Switch to 3G.

From the options, tap on “CDMA only” or “3G.” This will ensure that your device will use only 3G instead of 4G.

Numerous controlled scientific studies of 2G, 3G and 4G technologies have shown that stress, sperm and testicular damage, neuropsychiatric effects, including changes to electrical activity in the brain, cellular DNA damage and calcium overload can all occur in humans as a result of exposure to EMFs.

In relation to wireless networks (including 4G LTE) and health, the conclusion from the WHO is; “Considering the very low exposure levels and research results collected to date, there is no convincing scientific evidence that the weak RF signals from base stations and wireless networks cause adverse health effects.”

Your 4G or LTE data from your phone is often faster than your home Wi Fi. You would probably expect this to be the other way around, especially since your Wi Fi router relies on a fixed-line broadband connection, rather than having to connect to the nearest 4G tower.

4G Connection

4G internet is accessed through your mobile network provider and is available anywhere you have cellphone reception. Data sent and received over a 4G network is encrypted, thus, making it safer than a public Wi-Fi network.

Summary: Location leak of the mobile phone may include forcing the 4G device into revealing its location. The target user can be localized within a 2 km2 area in an urban setting.

A. On a typical 4G LTE network connection, your data is encrypted and your identity is authenticated and protected. Although 4G LTE connections are generally considered more secure, the software is not impenetrable.

What is LTE? LTE, sometimes known as 4G LTE, is a type of 4G technology. Short for “Long Term Evolution”, it’s slower than “true” 4G, but significantly faster than 3G, which originally had data rates measured in kilobits per second, rather than megabits per second.

Security researchers have long warned that spies or hackers could exploit the protocol supporting 3G — known as Signaling System No. While the new research indicates 4G is vulnerable to a smaller scope of attacks than 3G, it shows that attackers could shift a user’s device to 3G mode to exploit the less-secure SS7.

5G is potentially so susceptible for cyberattacks because of its possibilities and flexibility. Everything is managed by software and so that in itself has a security risk. Even core networks are virtualised in software.

Typically, Wi-Fi connections are more secure for transferring data between a router and a computing device, and they experience fewer technical difficulties. While 3G network connections are generally secure while data is in transit, they experience more interference and connection failures than Wi-Fi connections.

Really the answer to your question is that 3G is pretty secure, but it has its flaws. 3G is encrypted, the most common encryption algorithms have been cracked, with the right equipment somebody could intercept your information wirelessly.

Summary and More Info

Whatever the dangers of cell phone ‘radiation’ may be, it seems fair to say that the dangers are 10 to 100 times less from each Bluetooth and Wi-Fi device.
