摘要：We are seeing demand for broadband services is continuously exploding. So, mobile wireless networks must expand greatly their capacities. Here we are reviewing the economic and technical challenges associated with wireless networks to meet this exploding demand. The paper first reviews a brief technical background on mobile wireless networks and these basic methods to deepen their capacity. We can divide the Methods of capacity expansion into three general categories: the deployment of more radio spectrum; more intensive geographic reuse of spectrum; by increasing the capacity of each MHz of spectrum within a given geographic area. We find that without significantly increased allocations of spectrum, wireless capacity expansion will be wholly inadequate to accommodate expected demand growth
