Point-to-point microwave has a place in the future
Mobile radio technology is moving from 4G to 5G, but it cannot move in isolation. Operators learned this valuable lesson with the move to 4G. In particular, the transport layer, often referred to as mobile backhaul, became a network choke point at cell sites with upgraded 4G mobile radios and legacy backhaul systems. To avoid these past mistakes, operators are placing as much emphasis on the transport layer as they do on 5G mobile radios.
5G will need more backhaul capacity
One area of concern for operators planning their transport layer is determining whether the mobile backhaul network must shift away from wireless systems, such as point-to-point (PTP) microwave, to fiber-based systems, such as packet transport network (PTN) systems. The main issue, of course, is not the cost of the equipment; it is the cost of either installing fiber, maintaining fiber (ex. fixing fiber breaks), or leasing fiber. One of the benefits of a wireless backhaul system is the freedom from incurring the high cost of owning a large fixed asset—a fiber plant….
