The Cost of Quality

The advantage of wireless is that we have added mobility to the user experience. After
20 years of using cellular phones, however, we take mobility for granted and now
expect to have the same services available to us in a mobile environment as we have
from fixed access networks. Not only do we expect the same services, we also expect
the same service quality.
Service quality metrics such as consistency can only be delivered from relatively
dense wireless networks with robust and stable signaling—the cost of consistency.
Low bit error rates and low-latency metrics also require relatively dense networks and
robust and stable signaling—the cost of quality.
We have defined content quality in terms of frame rate, resolution, and color depth.
