BROADBAND IN THE MAGIC CITY: What’s the point of edtech if schools don’t have the wireless access to support it? That’s Miami’s feeling--and why they’ve gone wireless across the board. Miami-Dade Superintendent Alberto Carvalho announced at SXSWedu that “as of last Friday, 47 mil. sq. ft. of space in Miami-Dade has very strong, wireless, high-speed Internet.” Signal to other districts--time to jump on the bandwagon! And it might be wise to consider Comcast as a provider, who announced on Tuesday that it’s extending its “Internet Essentials” program providing cheap broadband service to low-income families in the United States.
