Is the line of sight really necessary?
Yes, line of sight is always required. Direct line of sight means that there should be no physical obstacles between imaginary line connecting the two points. • What is Fresnel Zone? Fresnel Zone is the area around the line of sight that radio waves spread out. This area must be clear of obstacles. Otherwise the signal strength is going to be weakened. For example, in the middle of a 16km link at 5.8GHz, 60% of the fresnel zone is a circle of about 8.7m radius. It is 13.6m at 2.4GHz for the same distance link. • Can I wirelessly bridge two networks? Yes, you can use MikroTik wireless routers to transparently bridge two networks. See the RouterOS documentation for more information. • Is there special license required to use your equipment? The equipment operates in the license-free ISM band. However, type approval certificates might be required for the radio devices in some countries. Some countries require to obtain a permit to use the frequency. What is a basic startup package for the
