High Speed broadband is facing a problem of the access network – which is a bottleneck for service provision. There are multiple solutions, suggesting how the one can overcome that problem. Solutions can be categorized in three main groups:

• optical access technologies (PON);

• wireless technologies (WiMAX);

• copper cables, short reach DSL, and twisted-pair subscriber lines.

   

Combining wireless and optical technologies can be advantageous in many ways. The most obvious way of combining those two is using optical solution for wireless base stations backhaul. The traffic would be passed to the switching centres or concentration points that are located further away from the base station. Modification of this system is the “radio over fiber” (RoF) transportation from the base station/access point to centralized processing unit. It reduces costs, complexity. and simplifies the network. Even the metropolitan network can be combined together with the wireless technology. This combination would show itself as a capacitive, flexible, and mobile combination of two technologies. Both systems can be used as the backup system for each other. In the event of failures the failed system can rely on the capacitive power of backup one. Combination of two systems can also provide increased flexibility with the use of applications of wireless techniques and modulation formats.

Subscribers demands would be satisfied in full capacity, since optical-wireless integration extends high-bandwidth backbone network.
