The city is dialing back its outdated pay phones, and replacing them with a 21st century twist. “Link NYC” is the new digital network that’s set to replace the city’s current 8,400 pay phones. The phones will serve as free Wi-Fi hot spots, with a radius of about 150 feet. The kiosks installed by CityBridge LLC will also allow New Yorkers to make free phone calls and charge electronic devices. The city plans to install about 10,000 booths across the five boroughs. The first high-speed public Wi-Fi hotspot kiosk was installed at the intersection of 3rd Avenue and 15th Street in the East Village. The kiosk was not operational yet as technicians still need to test the equipment, but it should be online within two months. The project will be paid for using the anticipated revenues from digital advertising on many of the kiosks.
