Here's How it all Works.

Our unique and state-of-the art technology allows us to put a wireless signal virtually anywhere!   How does it work? Let us explain the secret to help you understand why our service is the right one for you.

3dB Wireless High-Speed Internet Service is provided via our state-of-the-art Wireless Broadband System. Unlike DSL or Cable services we do not depend on the availability of telephone lines or cable TV infrastructure. This allows 3dB to rapidly deploy service into areas with no other services available. 

All that's needed is a small subscriber module mounted on the customer's premises. The subscriber module allows a line of sight wireless connection to one of our broadcast towers located within a distance of up to 15 miles. Each tower is in turn connected via wireless link to our Network Operations Center which provides the High-Speed Internet feed. The wireless link between your computer system and the Network Operations Center is a proprietary system that uses "Authentication" and "Encryption" to protect against security threats. 

The subscriber module also connects to your computer or broadband router via a standard CAT-5e network cable. A small AC power adapter powers the subscriber module over the CAT-5e network cable. 

The subscriber module also acts as a firewall to protect your network from direct Internet attacks, providing you with peace of mind. As a 3dB Wireless customer you will receive superior internet and customer service. It's all just a phone call away. 

The Site Survey 

The site survey is important. Simply put, we need to determine if the signal distributed from our local tower can be received where you live at a good signal strength level. Scheduling a site survey with us does not obligate you to purchase, but it does helps us see if you have the necessary "line of sight" to get the fastest service possible. In short, the fact that you can see a location does not mean you can establish an adequate radio link. 3dB Wireless requires certain minimums in order for you to be associated with our network. If you can't achieve these minimums we will not be a good fit for your Internet needs. 

There are ways to improve line of sight and signal strength, and we suggest you first get a technician to determine your specific Line of Site to ensure the most reliable, fastest Internet service possible. 

Understanding High Speed Wireless Line of Sight 

Transmission of our service requires a clear path, or 'Line of Sight' between our tower and your home or business. Line of sight is the unobstructed area that would exist between two points. 
• You might think this is a pretty simple concept.
• You might think if you could see the top of the tower with binoculars, you have line of sight.
• You might be wrong.

Your necessary visual link could be obscured by buildings, terrain such as mountains, bluffs, low spots and even trees. If any obstruction interferes or blocks the view, then you have impeded line of sight. Impeded line of sight could mean frustration for you and us. 


Our technology forces us to take into consideration the Fresnel (frenel) Zone effect. If a hard object, such as a mountain or building is too close to the signal path, it can hamper the radio signal or reduce its strength. This can mean slow speeds, intermittent service, or other things that will make your Internet experience frustrating and un-enjoyable. The effect will happen even if the obstacle does not obscure the visual line of sight. 


As the picture indicates, when a solid object protrudes into the signal path within the Fresnel Zone, there can be intermittent deflections. This signal is now slightly out of order and can reduce the signal's overall power or cancel it out altogether. The result is an unhappy experience for you. Trees or softer objects protruding into the Fresnel Zone can also reduce the signal strength of the radio path and result in unsatisfactory service.
