If we decided to setup a wireless network only for the access to a broadband service provider (assume HGC) because they are FTNS licensee. We (assume as an OC) we can apply for a class licence from OFTA to setup a wireless network only to serve the residents of RC. Becasue 2.4G 802.11B/G is a free band we can use without paying any additional licence fee.
What we need is not very costly only a few outdoor AP and several Omni antenna will work.
