45 Mile Wi-Fi Range is Now Possible with Lower Power Consumption

On-Ramp Wireless has invented a new way to transmit Wi-Fi signals that actually uses less power to strengthen the signal.

Wi-Fi signals become more and more distorted as they travel through the air and, of course, after a while they become too distorted to be useful (after one-twentieth of a mile) due to noise.

This is basically what limits the range to the interior of buildings and this also limits the potential applications of Wi-Fi to those in buildings.

Imagine connecting wirelessly and cheaply to someone 45 miles away without using the internet? And how about while using less energy? You could also eliminate all of the network cables in the largest buildings cheaply and efficiently. The transmitter in the image at the top of this page can reportedly do all of that.

This transmitter achieves that by utilizing an algorithm that transmits it at the same frequency, but in such a way that it is more resistant to noise so it can propagate through the noisy environment over a 45-mile distance.

Another energy related advantage of this is that it would make fewer smart grid access points a possibility due to the fact that traditional access points don’t transmit nearly as far, so more are needed so that more access points are closer to homes and businesses with smart meters.

The smart grid concept involves using computers to enable power plant operators and residents to more effectively match the power production of power plants with power demand to reduce the imbalance of daytime and night time power consumption, and especially to help with the variability/intermittency of solar– and wind-powered generators to increase their market penetration.

I will keep my eyes peeled to see where this technology goes and keep you updated if I can.

Thank you for reading and please comment below if you have more thoughts.

    What I mean is that how can I creat WiFi connection to mass consumption,I want to go into the business in Nigeria.

    • Bob_Wallace

      You might try contacting the company I use. Ask if they will give you some basic information and whom you would contact to purchase hardware.


      There’s an email address on their Customer Support page.

    How can I creat a WiFi to sell megabites for my community?

  • This article has been up for three days and nobody noticed the missing verb in the first sentence?

  • kodandaram Balaji

    looking for more clarification, product details & spec, speed. can we also send tv content along with data

  • Wavemissions

    Whats the cost????

  • Jonquid

    If there is a satellite everyone or anyone can hear?

  • Anonymous

    I’m posting this via a wifi connection. The other end of my wireless internet connection is 33.7 miles away.

    (My previous wireless internet connection was a few hundred miles up in space, but that’s a different technology.)

      What is your data rate? Are you using On-Ramp?

      • Anonymous

        Just did a speed test – 7.61Mbps down, 1.41Mbps up.

        Using a local company called 101 Netlink.

        I’m past their normal range and am using an external antenna.
