China Wireless Communications utilizes digital broadband radio systems, or "Wireless Fiber" to provide the capacity and reliability of fiber-optic networks, with the fast deployment and targeted capital spending only available through advanced wireless technologies.

We utilize two types of radio systems; point-to-point, and point-to-multipoint. Each one has its own purposes. In point-to-point networks, there is a dedicated "link" between two points, with a radio system consisting of indoor radio electronics and an outdoor antenna, installed on each end of the link. One end of the link is called a "hub" site. The hub site typically has multiple antennas, each with a corresponding set of radio electronics. Each antenna at the hub site points to an antenna located on an end-user building at the other end of the link. The end-user building radio system completes the link, offering dedicated, secure connectivity between the two locations at speeds up to 155Mbs. The multiple end user buildings look like "spokes" coming from, or connecting to, the hub.

In point-to-multipoint systems, Wireless point-to-multipoint broadband networks allow transmissions between multiple customer antennas and a single base station antenna, thereby allowing CWC to share the same spectrum among its customers and reducing its capital expenditures. One end of the network is a "base station" radio system that acts as an aggregation point. In most cases, the "base station" radio system is co-located on a "hub" site with other point-to-point and point-to-multipoint radio systems. The end-user building has a radio system (electronics and antenna) called a "subscriber unit". Multiple subscriber units within a "sector" are pointed toward one base station, where the traffic is aggregated. Connection speeds from each subscriber can vary from 256Kbps to 10MBps.
