在无线电频率网络上的个性化交互式视频通信服务成为现实之前，必须克服几个问题。能够支持无线视频服务的挑战是重大的，因为视频通常被认为是带宽消耗大、对错误敏感、有时不能容忍延迟的；另一方面，无线电信道的特点是具有有限的容量和高误码率，并且是时变的。在这种恶劣的条件下，作者探讨了在基于基础设施的无线网络上支持实时数字视频通信的问题。所描述的工作背后的指导思想是，如果网络、操作系统和应用层中的不同组件彼此合作并与整个系统合作，那么健壮的无线视频通信是可能的。
Several problems have to be overcome before personalized interactive video communication services over radio frequency networks can become a reality. The challenge of being able to support wireless video services is significant since video is generally recognized as being bandwidth-hungry, error-sensitive, and sometimes delay-intolerant; radio channels, on the other hand, are characterized as having limited capacity and high bit error rates, and being time-varying. Under such hostile conditions the author explores issues in supporting real-time digital video communications over infrastructure-based wireless networks. The guiding philosophy behind the work described is that robust wireless video communications is possible if the different components within the network, operating system, and application layers cooperate with one another and with the overall system.
