How to improve poor indoor cell phone signals

Building materials such as concrete and tinted glass, along with siting of buildings in shaded areas all conspire to diminish the strength of indoor cell phone signals. You may have a good home cell phone signal and then change providers only to find that your new network gives you poor reception indoors. The positioning of the network's signal towers will also affect your reception. Luckily, new technology offers a potential solution to the problem. Whether the cell phones are needed at home or in an office, there are now steps you can take to improve indoor cell phone reception.

Skill level:


  1. 1

    Report the problem to your cell phone provider and to Your supplier probably won't take much notice of an individual call, but collects data about addresses with bad indoor reception to try to ensure better future coverage from providers. This solution will probably not happen in time to sort out your particular concern, but will help others in the future.

  2. 2

    Buy a cell booster for your home. These devices consist of an amplifier and an antenna and are placed in an area where there is already some reception. If there is no signal at all, there is nothing for the booster to work on so, unfortunately, you will be stuck with your problem. The booster works by amplifying and repeating the signal it receives, giving you the extra reception that you need. There are single-user and multiple-user options along with differently powered alternatives--external power adaptor or USB-powered, for example. Your choice will depend on whether you want it for home or travel use.

  3. 3

    Have companies like Spotwave and InnerWireless help you increase your indoor coverage if this is a business. Working along with your wireless provider, you can have these companies install a signal base station inside your building. An outdoor antenna will need to be erected, but if this minor inconvenience can be overcome (and your landlord and neighbours agree to it), an internal base station could alleviate indoor reception problems.

Tips and warnings

  • The Clever and Easy website points out that there are two bonuses with the use of cell phone boosters. Apparently the cell phone works less hard with a better signal which uses less battery strength, making it last longer. Also, the improved signal means your cell phone needs to emit less potentially hazardous radio waves.
