Several readers responded with their thoughts on last week\u2019s newsletter on wireless LAN hot spots, and I\u2019d like to share their responses with you.One reader says WLANs have a short-term edge that could develop into a long-term one:\u201cWLAN has its place and will continue to see new growth in more places. One of the reasons is the 3G technologies are considerably more expensive to deploy and maintain.\u00a0 This means the end user will pay significantly more to use it - at least in the short term. This gives WLAN (Wi-Fi) more time to mature. More time for it to gain greater consumer acceptance. More time for the consumer to become dependent on its availability.\u201dBut in the case of failed Wi-Fi venture Cometa Networks, even if the company had managed to get McDonald\u2019s to sign up, this reader at least wouldn\u2019t have been very receptive:\u201cCometa Networks press continually made reference to its McDonald\u2019s account. I really don\u2019t think about going to McDonald\u2019s to do ANY PC work. The environment just is not conducive to this exercise. If I had 100 choices for a Wi-Fi venue, a place like McDonald\u2019s would probably rank about 99.\u201dWayport in May announced that it won the contract with McDonald\u2019s and will roll out its Wi-Fi service to 8,000 of the fast-food restaurants over the next year.Another reader says it\u2019s all about latency:\u201cLatency is the big technical difference between WLAN and cellular services, i.e., probably less that 100 milliseconds for WLAN and probably more than 500 ms for cellular. This doesn't matter for surfing and E-mail, but when people start using wireless for connectivity to business apps, like so they can work while waiting for a plane, response time will be more critical.\u201dYet another reader had this to say about the possible rise of WiMAX, the high-speed follow-on to Wi-Fi:\u201cTechnology is only the enabler when it comes to applications. If the application is not interesting, or if the application is too expensive, or if the application is too cumbersome to use, the best technology behind the applications is meaningless. It is too early to say if WiMAX can even survive, let alone prosper. Ultimately, it is what the service provider and what the carries trying to do with WiMAX. At the moment, I see mostly a bunch of start-ups and Intel\/TI waving the flags because they want to make money. The takers are largely quiet, in my limited view of course.\u201dMany thanks to all who wrote in.
