New client supports secure roaming: PCTEL's Segue roaming software supports 802.1X and WPA and lets users scan for Wi-Fi and cellular data networks. The company hopes the client will make it easier for folks to use Wi-Fi networks because it offers an easy user interface and security. PCTEL is giving away a trial client which you can download on its Web site.
I'm not really sure how this is helpful. It's really not that hard to figure out which Wi-Fi networks are around. Then the question becomes: how can you get on the network. PCTEL's client doesn't help with that.
Maybe the focus is really on finding which cellular networks are nearby in case no Wi-Fi is available. But you have to be a cellular customer to use their network for data so you'd probably already know how to figure out if you're in range of the network.
Finally, it's lovely that it supports 802.1X and WPA, but local networks have to have that wired in as well for it to be useful, and no public networks we're aware of have rolled that out yet. (Glenn suspects 802.1X might replace gateway pages but only when secured EAP along with clients for many OS's are freely or at least widely deployed.)
