1. Here's How It Works

reach case is the only case on the market that expands your antenna to improve your phone’s signal strength. Embedded inside the case is a multi-patented, micro-thin antenna that automatically pairs with your phone’s antenna to improve performance. As a result, you experience fewer dropped calls, greater coverage, and better data speeds. When you’re in areas with an especially weak signal, open the sliding mechanism on the case to maximize antenna performance.

It is important to note that the reach case can only improve reception if there is a signal available. If the area has absolutely no signal, the reach case will not create a signal.

2. Will reach case give me more bars?

reach case is always working for you, even if you don’t see your bars increase. To better understand this, let’s take you behind the bars and explain how mobile phones display their signal.

Your phone simultaneously transmits a signal to, and receives a signal from, a cell tower. The bars on your phone show how much signal it is receiving from a cell tower. reach case improves both the transmitted and received signals.

A phone’s signal strength is quantified in dBm (which stands for decibels referenced to one milliwatt). You will always see a negative dBm on your phone (which means the received signal is less than one milliwatt). The closer the number is to zero, the better your signal strength. In addition to rigorous lab testing, reach case is also tested on the live network—results show an average improvement of 3dB. Each bar equates to 10dB of signal, so the signal improvement provided by reach case may not always lead to an increase in bars.

If you want to be a pro, you can put your phone into field test mode, which will show you the numerical number dBm rather than just bars.

3. 3dB Improvement is significant

Signal strength uses a logarithmic scale, which means an improvement by 3dB is equivalent to doubling the signal. It’s proven that even a few extra dBm can make a significant difference in improving call quality and data speeds. This is especially noticeable in areas where your signal is weak.

Remember that reach case is also improving the signal transmitted from your phone to the cell tower—this helps you reduce drop calls and STAY CONNECTED farther from the cell tower.
