Wilson 801201 Mobile Wireless Amplifier

This amplifier captures weak cellular signals from outside your vehicle using an external antenna, boosts them, and rebroadcasts the stronger signal inside the cabin. It specifically targets two cellular frequency bands to improve your phone's ability to maintain a connection, resulting in fewer dropped calls and more consistent data speeds.

This device supports Band 4 and Band 5, which are commonly used by major carriers for 4G LTE and older network technologies. Because carrier frequency usage varies by location and provider, it is best to check which bands your carrier uses in your area before relying on this specific model.

The Wilson 801201 provides up to 50 dB of gain. In practical terms, this is a significant boost that can turn a 'no service' or 'one bar' area into a usable signal, provided there is at least a faint signal available outside for the device to amplify.

Installation is designed for a vehicle environment and typically involves mounting an external antenna, running the cable to the amplifier unit, and powering it via the included DC car charger. While it is a straightforward process, you will need to route cables discreetly through your vehicle's interior panels for a clean look.

While this unit effectively boosts signal, its status as a discontinued product means it lacks support for newer 5G bands and advanced network technologies used by modern carriers. If you are looking for a long-term solution that will work with the latest smartphones and network standards, you are better off looking at a current-generation model.
