A company called On-Ramp Wireless invented a technology that uses the same frequencies Wi-Fi network cards use, but modulates the signal in such a manner that it doesn't get distorted by noise, such as the surrounding networks. On the contrary, the Ultra-Link Processing technology can send signals to up to 45 miles and even uses much less power to do that, enabling savings in what concerns both energy and equipment deployed on the field by utilities.

The development of alternative energy has to go hand in hand with a reinforcement of the electrical grid, otherwise the latter will eventually become so busy and will cap the production to its capacity. Such is the case with Germany's grid, which is an example of an imbalanced structure of solar and wind energy harvesters on one hand and the outdated grid, on the other.
