68: Optimizing the Front-end for Mobile and Tablet Sites





Great idea:
“More often than not, the mobile experience for a web application or site is designed and built after the [desktop] version is complete. Learn the three reasons web applications should be designed for mobile first instead: mobile is exploding; mobile forces you to focus; and mobile extends your capabilities.”


How fast is 4G, really? Can I cancel my ISP subscription yet?


4G has the potential to be insanely fast. The various technologies should be able to deliver download speeds of 1Gbps when stationary (in the home), and 100 Mbps while mobile. Those kinds of speeds make cable and DSL networks look like dial-up.

In practice, neither LTE or WiMAX is going to offer that kind of speed. In the best of circumstances, users can expect around 10 Mbps from WiMAX or LTE. As coverage areas increase and networks grow more robust, that number could increase.

T-Mobile’s HSPA+ network already tops 21 Mbps in some areas. Realistically, users can expect about half of that. But T-Mobile and AT&T both plan to upgrade the HSPA+ offerings on their networks.

Most users will not be able to replace a home Internet connection with 4G, and that likely won’t change for several more years, at least. The exception is users in rural areas, where it’s often extremely difficult to get cable, fiber or DSL, and who have to rely on satellite Internet. For these users, even the first wave of LTE or WiMAX may be speedier than what they get from satellite — and at a lower price.
