LEED certification is a great benefit to buildings and their ongoing operating costs. The energy saving techniques used offer benefits during construction and ongoingly. When these benefits cause wireless service to fail or perform poorly, it becomes a double edged sword. E-Glass blocks cellular coverage and wireless Public Safety signals from entering or exiting your building that’s bad. The fact that it also and blocks Wi-Fi signals from leaving your building, well that’s good, unless you wanted your parking areas covered. In all these cases, knowing bout it is the first step… fixing it is the second.
Below is a chart of E-Glass loss and you will see it is at least 33dBm of RF loss, that’s a 1,100% drop in your connectivity. Yes, an 11 fold loss of signal, regardless of which of the cellular provider or what frequencies bands you are connected to. Depending on the e-glass used you may experience losses in the 40-50dBm range. PPG published this chart which shows their test results.
So E-Glass is beautiful, but if you stand indoors on a winter day with the sun on your face, take note if your face doesn’t feel the warmth of the sun’s rays. In that same way the RF signals we have come to depend on using everyday are also being blocked. To fix the issue you have to repeat or re-broadcast those missing RF signals inside your building. That’s where VentusRF can help. Give us a call and we can discuss your exact issue(s) and provide you the right solution for you.
