Ironic poor connectivity in Silicon Valley

I am always amazed when visiting the Bay Area (aka Silicon Valley) in terms of the poor connectivity – both in terms of Wi Fi coverage and cellular phone coverage. Weak signals on the mobile phones. What little Wi Fi there is is often corporate or proprietary (e.g., T-Mobile’s) and a bit on the expensive side (compared with Wi Fi in Asia). Seems quite ironic that connectivity is so poor in the heart of the global innovation engine.
