Turning on the Drive Sleek generated immediate improvements. I took a number of measurements on each device and network in known areas of strong and weak coverage to set some baselines. I tested the Drive Sleek with an iPhone X on AT&T, a Pixel 2 XL on Project Fi (T-Mobile), and a Galaxy Note8 on Verizon Wireless. WeBoost claims the Drive Sleek provides a maximum gain of 23dB, and, goshdarnit, it does. Signal strength of 50dB is more or less perfect - meaning you have a raging fast LTE pipeline all to yourself - while a signal strength of 120db is call-droppingly awful. These are typically buried in your phone's settings screen. Those are garbage and basically just tell you if the network is available. Forget about the bars at the top of your phone's screen. Just a quick reminder on how to measure signal strength. The kit includes an external antenna, a booster module, and a phone cradle. It involves three major components plus plenty of wires. WeBoost included a series of dead-simple directions to set up the Drive Sleek. WeBoost makes a range of such products, and the Drive Sleek is its latest offering for passenger cars.

Signal boosters use a large(er) antenna to capture existing wireless signals and improve them in small areas, such as a home, office, or vehicle. Your phone needs all the help it can get to stay connected while driving. Smartphone antennas are small and can only do so much to gather cellular signals as you move around, particularly at 60mph.

The antennas inside modern smartphones are more advanced than ever, but there's still no beating the laws of physics. On top of that, high speeds create a doppler effect that that your phone and the network must account for. In less than an hour's driving, your phone might encounter every conceivable signal-related challenge a phone could possibly be asked to deal with. As you move around, you encounter quickly changing network conditions. Driving presents a special challenge for cell phones.
