For example, a reading of -86 dBm (or 86 dBm) is stronger than -91 dBm (or 91 dBm). Regardless, a signal strength reading CLOSER TO ZERO is stronger. But on some phones the - sign is omitted, so the reading displays as 91 dBm instead. The reading is often displayed as a negative number, like -91 dBm, for example. The signal strength reading is typically displayed in decibels (dBm). Once the signal strength reading is displayed, you will get readings facing all four cardinal directions (North, South, East, and West). Or you can use a search engine to find the term "Signal Strength Reading' or 'Field Test Mode.' Or contact your phone manufacturer's customer service department. Consult the operations guide that came with your phone. Where to find the signal strength reading in your phone's menu tree varies by manufacturer, model and operating system. Once you know the tower location, point the main center beam of the Yagi in the direction of the cell tower.ĭisplay your phone's signal strength reading. You can use a search engine to find one of the many tower location sites on the Web. If you want better Verizon coverage, for instance, you’ll get it, but you’ll also help your brother who uses AT&T out.First, find out where your cell carrier's nearest tower is located. They create significantly more coverage area than a femtocell, for all carriers at once. If any signal exists on your property you can harness, a cell phone signal booster is simply the better choice. Third, their coverage area is small, and will only affect the one carrier. Second, many carriers have discontinued their brand’s femtocells, as they felt keeping their customers connected in this way wasn’t an effective investment. First, they require landline internet to function. There are quite a few drawbacks to femtocells, however. A femtocell can create signal in a very small area (around 1-2 small rooms) by plugging in to your home’s Internet connection. A cell phone signal booster cannot function without existing signal to boost. We’ll keep it short and sweet here: a femtocell is your best solution if you have absolutely no signal anywhere near your home. There are two common ways to improve cell signal in your home: a cell phone signal booster, or a femtocell (also called a microcell).
