Getting To 4g Through Design And Test

摘要

As today's telecommunication technology proceeds forward to 4G (fourth generation), it requires a minimum network speed of 100 Mbps in high-mobility situations and 1 Gbps in low-mobility scenarios. The goal might seem more manageable if 4G represented an ultimate goal-that is, a finish line. Instead, it is only the latest point in a continuum that stretches beyond the foreseeable future (Figure 1). Whatever level of performance engineers can deliver, customers will find reasons to demand more. In short, data expands to fit the available bandwidth. In other words, if you build it, the data will come, and the infrastructure to support that performance must also evolve.
