Invisalink is always growing to meet the demand for high-speed Internet by expanding our network throughout our service area. We use a number of advanced technologies to make our services available for home or business. This system works by connecting you to the Internet via a radio and antenna system.


THIS IS NOT SATELLITE. It is a ground-based system of towers transmitting the signal(radio frequency) to your home, then converting it to the feed your computer receives. The only wiring required is used to connect your computer to the wireless radio. All receiver equipment is installed outside the residence and/or business.

Invisalink uses quality equipment by: Ubiquiti, Mikrotik and SAF.
