Sierra Advantage is proud to make some of the most advanced wireless Internet technology available to residents and businesses in its service area. The technical term for our service is "Fixed Wireless Broadband Internet," which is exactly what the name implies - high speed (broadband) Internet service without wires, fixed to specific locations (i.e. not intended to be mobile).

Unlike traditional terrestrial high-speed Internet solutions, which are delivered over telephone wires or television cables, our wireless high-speed Internet travels by radio waves from our network center to your location. This system utilizes a hub-and-spoke-like topology that is composed of multiple relay and repeater sites. This method effectively compensates for the hilly topography of our region. The end-point of the system is at your residence or place of business, and consists of a small outdoor directional antenna mounted so that it faces the nearest repeater site. This low-voltage customer-premises system is powered over the same cable that carries the data signal (using "Power over Ethernet") from the outdoor antenna indoors to your computer, hub, or router.

The Sierra Advantage wireless network has been engineered and designed for reliability and performance. Our technology employs several radio bands between 900 MHz and 5.8 GHz that have been allocated by the FCC for wireless data services. By utilizing different frequency bands for different legs of the network, we can maximize the data carrying capacity and performance of the system. Do not confuse our technology with basic low-cost "Wi-Fi" - the technology commonly used in homes, businesses and public locations to allow laptop computers or PDAs to be wirelessly connected to the Internet. Our equipment is very sophisticated and utilizes a number of techniques that solve common wireless Internet problems such as radio spectra noise, interference from other wireless devices, and collisions of data packets caused by heavy usage from a large number of subscribers.

And although our "last mile" signal is still Wi-Fi compatible, the difference between ordinary Wi-Fi and our solution is that we use much more powerful transmitters and directional antennas, whereas ordinary WiFi uses very-low-power transmitters and omni-directional (meaning in all directions) antennas. The benefit of this Wi-Fi compatibility, if you have a laptop or other mobile computer, is that you don't need a separate Wi-Fi access point when you have our service - your exterior antenna can act as your default Wi-Fi access point.

To ensure reliability, all of our repeater and relay sites are protected by battery-backup power supplies. But should any relay site go down for any reason, the system automatically detects the condition and seamlessly reroutes traffic to other nearby repeater sites. Our network center is likewise protected with backup power systems and generators. We also have fault tolerance in all our critical equipment, including redundant Internet backbone connections, to automatically handle most potential failures.
