Wireless Networking Resources

"Wireless Connectivity is very important for portable electronic devices. The technology has developed so well that small batteries, small flash storage and low power wireless is practical today. This makes Tablets and Wearable computer even closer to becoming the way computing will be done in the future.

The only bottleneck is that the mobile broadband still cannot manage that kind of data load at an affordable price. Something like the WiMax or Bell Labs' lightRadio Cube should take off and remove this Road Block.

We are now waiting for that Historic Invention that makes fiber-broadband and mobile-broadband converge to make the Digitally Connected World a Reality". - Aug 2014

More of My notes

Set up your own Wi-fi Hotspots or WiMAX regions to enable broadband. One thing i strongly feel, my technical opinion only. A Gut feel that says that the Mobile type technologies like 3G or beyond are not built the way that a TCP-IP Network like Wi-Fi is. .....below

Nothing less than a Wi-Fi like Experience with same connectivity and costs, will work long term, to user satisfaction. Many Many Users, Many Many Videos, Games, Downloads, Updates,  .. Think again.

WiMAX with Those small Cubes that Bell labs made may be just what we want - Alcatel-Lucent - lightRadio.
