What Should I Look for When Buying the Best Mobile Signal Booster?

It’s apparent that so much of our everyday life depends on mobile phones. Twenty years ago, it was not possible to deal with your clients while picking up some necessary items at the grocery store. Or you could never connect to your colleagues from the office for an important matter while caring for your sick child or parents. In other words, mobile phones gave a new meaning to the term “multitasking.”

But issues, like weak signals, slow data speeds, or dropped calls can have significant impacts. Luckily, boosting coverage for mobile phones is now possible. However, not all cell signal boosters are created equal. Consider these factors when buying to avoid wasting your hard-earned money:

1. Determine the Signal Strength Outside First

Firstly, you have to determine how strong the outside signal is at home or in your office. Remember that the signal may become weaker when you’re inside a building due to the construction materials used. Fortunately for new buildings, section 510 of the International Fire Code requires owners and contractors to have in-building radio coverage for emergency responders.

Go outside and see if the signal improves. If you have a stronger signal, you know where the issue is coming from. Possible reasons for weak signals outdoors could be the proximity of towers, other obstructions like trees, mountains, weather, other buildings, and your carrier.

2. Where Will You Install the Signal Booster?

Find out if your entire office or home has a general weak signal problem. See if only a specific area in your building needs a cellular amplifier because signal boosters are designed for all kinds of space. For instance, if your space (basement, single office, apartment, home-based office) is about 150 square feet to 1,500 square feet, 4G is perfect. 

3. 5G Compatibility

When you’re looking to boost mobile signal in a commercial space, amplifying 4G LTE is probably the top choice. But why don’t you optimize indoor cellular coverage through a solution that works with 5G as well? For a modern business, you need to think of the future, not just meet today’s demands.

With a 5G signal booster, you will end signal issues caused by trees, buildings, or other obstructions. It will boost the outdoor signal into your building so you can have faster data speeds, better voice quality, and reliable signals.

4. Highest Gain in Decibels

Look at your dual-sim smartphones. You might notice that one has three bars while the other has one bar even with the same signal strength. Avoid using this as a basis when choosing a mobile signal booster. Instead, go with decibels (dB) Gain. 

The higher the positive number Gain booster, the stronger the signal. So, +70dB is better than +60dB because it adds more Gain to signal strength. Be aware, though, because a negative number such as -80dBm is higher than -90dBm (Decibel Milliwatts) since the first one is closer to zero.

5. Compliant with FCC (Federal Communications Commission)

The Federal Communications Commission (FCC) has released new guidelines and regulations regarding the manufacturing and use of mobile phone signal amplifiers. Ensure that you choose a mobile booster that is certified, permitted, and compliant with all the regulations and guidelines by the FCC. You may visit the FCC website for updates on new compliances before you make your purchase.


Whether you need connectivity for your business or home, you want a stable connection and no dropped calls. If you believe you still need help after reading the guide above, consider working with professional installers to help you choose the best mobile booster that matches your needs. They are your go-to people since they have vast experience, understand cell towers, and know the tools.
