Why do you need to buy repeater/booster ?
Cell phone becomes especially helpful when people get into critical situations. In case of emergency a timely call can save somebody’s life.
Unfortunately, there are still some places where they can find themselves “out of coverage” ,no signal at all... Usually those places are either too far from the cell phone base station or located inside underground constructions, for example:
- · Parking lots, tunnels
- · Big stores, office buildings
- · Cars, boats etc.
- · House in remote areas
How can repeater bring your mobile phone better signal?
