DescriptionA large American city sought to convert over 7,000 payphones across the city into a public, citywide Wi-Fi network. The goal was to create free, encrypted, gigabit wireless Internet coverage and displays for public engagement by converting old payphones into slim-profile edge devices around the city.

In addition to hosting a WIFI hotspot or 4G/5G small cell, the new edge devices would need to support:
-Device charging via USB
-55” displays for advertising and announcements
-55” interactive display for users to engage with various software applications
-Emergency call button (E911)

Creating a system architecture for these complex, multi-purpose Internet of Things (IoT) devices across diverse locations into a consistent form factor was a challenge for the design team.

However, the multi-disciplinary design team collaborated to overcome the challenges to build a mounting system for the structure, choosing the correct materials for RF transmissivity and signal strength, preparing the systems for street side servicing, and optimizing the flow of components and electrical systems.
