One of the questions we get often in the technical support department relates to bars on your cell phone, and what they mean. Some folks assume that 4-5 bars on their phone is needed for placing calls, sending text messages, and browsing the internet. The common misconception is that a bar on your phone is a bar on my phone. This, unfortunately, is not the case. Bars of signal vary by phone and by cellular provider.
So what is a bar and what does it mean? Bars are a representation of how much signal you have. This signal is measured in dB (decibels). The bars are a visual way to show a range of signal – think of stair steps:
The numbers on the sides are the signal in dB (a negative value: -60 relates to being next to the cell tower, while -105 relates to where you can expect to start dropping calls).
So, what should your expectations be for a good signal? Granted, these are very general standards, as internal antennas vary by what phone you use. However, a signal of -105dB is the area where most phones start dropping phone calls, and text messages can fail. A signal of -80dB to -90dB is the recommended for using data/internet.
If you don’t have good enough signal – there are Wilson solutions for you. We would be happy, if you call or email, to recommend the proper solution for your needs. You can also leave a comment below, or connect with us on Twitter/Facebook.
