We all check how many bars we have on our smartphones and assume it’s an accurate guide to how strong our signal is. But what do those bars really represent?
“There’s no standard. They do indicate signal strength, but it’s up to the handset manufacturer to come up with whatever algorithm they want,” explains Steve van Skike, Senior Manager of Test and Regulatory for cell-phone booster company Nextivity. “They certainly want to do something that is appropriate for the consumer, it needs to be meaningful information, but the details are up to them.”
