Is QoS-unpredictable cable or DSL available? > Funny you should ask this, Howard. I've been struggling for several weeks how to pose the question. Have we, the engineering / technical sales community oversold the idea of dedicated bandwidth and QoS? Take, for example, wireless. Wireless is essentially a step backwards. For years we have been convincing customers to get rid of their hubs and move into a switched domain, with dedicated bandwidth for every user. This is often done in the name of productivity. Fewer interruptions of data streams, meaning work completed faster.Now all the wireless vendors ( Cisco included ) are producing studies showing how wireless is increasing productivity to the tune of an hour a day. On a shared contention medium. Cisco will shortly release their wireless telephone as part of their AVVID suite of products, competing with the SpectraLink product that has been available for a couple of years. All this gives one reason to re-evaluate what we have been told for the last couple of years. a contention medium provides the means for greater productivity? You mention QoS in your response above. QoS is something being pushed as necessary for voice, video, and other delay sensitive traffic. Cisco wireless AP's offer one way quasi QoS. Wireless, however, remains a contention medium, and will remain so until the FCC changes the rules. I'm not sure they will be able to release sufficient radio spectrum to permit all the bandwidth and services that wired can. But wireless is so damn convenient! I'm not suggesting that dedicated bandwidth to the desktop is a bad thing or that there is not need for QoS. However, I'm wondering how all of us might reconcile two seemingly opposed points of view regarding bandwidth and QoS - recognizing that wireless, whatever it's limitations, is here to stay, and will become and remain essential to any and all networks, enterprise or small business, going forward.
