The test used by the study to determine good signal strength in smartphones is often referred to as the antenna test. The study found that the main difference between smartphones when it comes to good signal strength is the design of the antennas in combination with how the smartphone is held by the user.
Interestingly the study found that good signal strength depends strongly on the antenna in the smartphone and on the way the user holds the smartphone to her head face during voice calls or in her hands during browsing. It was also found that good signal strength is achieved better through hands-free modes as the smartphones are then free from any close by objects (like your face) interfering with good signal strength.
