Ericsson Demonstrates SIM With GSM, WLAN Sign-On
As we move closer to a world where the cellular networks and WLAN networks co-exist we'll need devices that can handle both types. Ericsson is now demonstrating a SIM card that offers a single sign-on to both GSM and publice WiFi networks. Of course, in the article they suggest that this lack of a single sign-on has "held back the market", which I'm not sure is really true at this point. There are probably about twenty different things that have "held back the market", but all are being solved, one-by-one.
Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.
While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.
