In a new report, Bronx Borough President Ruben Diaz Jr. is calling on the city to pursue an environmentally friendly component to the new, free wireless network, LinkNYC, announced by the Department of Information Technology and Telecommunications last week. The new system, which will replace existing public pay telephones with devices to create the world’s fastest municipal Wi-Fi network, should include solar panels as part of the new installations. The design selected has several desirable features. However, the 24-hour battery backup is insufficient. After Hurricane Sandy, lower Manhattan was without power for five days. LinkNYC should be required to implement a design that incorporates solar power and reduces the network’s dependence on ConEdison.
