“internet light for all” May 2018, Josef NollBasicInternet.org Basic Internet @Basic4all
Digital Inclusion of everyone
● Business aspects ➡ OPEX, CAPEX ➡ Income models?
● Traditional business models are too slow ➡ Mobile broadband roll-out dominated by return on
investment ➡ Premier league, Bollywood outranges non-profit
content
• Providing at least one Information Spot in each village ➡ Internet lite for all - free access to information ➡ Paid access to profitable content - sustainable solution
“Providing Internet to the
basic of the pyramid isn't a
question of affordability, but
rather a question of
sustainability”

Challenges● Radio coverage
➡ how can we reach Izazi? ➡ what is the expected capacity?
● Business model - (A) fixed line vs (B) mobile hot-spot ➡ What needs to be the price for a voucher? ‣ Time, Amount, Validity
➡ Expense model based on OPEX ➡ Goal: Break-even
