There are many websites offering information, especially telecommunication companies, on their availability of services in an area. However, they don’t provide the frequency band details. They usually only show if they have 2G, 3G or 4G coverage. We have found a website that offers information on the cell sites in Australia that details the available frequency bands at particular cell site.
Visit Oztower web site http://oztowers.com/Home and go to search then type the postcode
For example: 2147, Seven Hills, NSW
It shows the entire cell site in the postcode area and the available 2G, 3G, and 4G frequency bands.
There is also an option to view from the map, the cell site location. You can select the cell site and from there you can view information of the cell site. In the red box those are the frequency that DrayTek Vigor LTE routers are supported
