SchoolBusHotspot.jpg Availability of Connectivity via WiFi
During the COVID-19 pandemic some local governments and companies have made progress through publishing online and through physical postings to map WiFi Hotspots.
K-12-teacher.jpg COWs COLTs Aerostats for Emergency Distance Learning and Telemedicine Broadband Connectivity in Rural Areas
This white paper describes COWs (Cell-on-Wheels), COLTs (Cell-on-Light Trucks), and Aerostats (CCAs) used to provide cellular or Wi-Fi connectivity in areas without 4G. They are used to provide emergency communications during catastrophic events such as fighting forest fires in rural areas, and in aftermath of earthquakes, hurricanes, or floods. In California there have been a series of state-level broadband meetings focused on the need to provide an immediate response to fill the distance learning and telemedicine broadband access gaps to unserved rural households sheltering in place during the COVID-19 crisis. Some telecommunications providers and public libraries are offering free Wi-Fi hotspots with 4G service to take home; however, 4G hotspots only work in areas with cellular broadband service.
Schenectady Downtown Revitalization600.jpg City of Schenectady, NY: Enhanced City Services
As part of Schenectady’s Lower Union Street reconstruction Project that started in late 2015, Smart Lights have recently been installed that allow the control of lighting and other sensors to monitor devices as well as provide a small scale Public Wi-Fi deployment. This deployment, activated on June 20th 2017 as Schenectady’s contribution to World Wi-Fi Day 41 , gives residents, and visitors within a 5-block area of State Street (from Broadway to Lafayette) access to the internet and is helping to identify value for further Wi-Fi deployment. 42 Wi-Fi access points also allow the city to control smart lighting and other IoT sensors that help in evaluating the benefits of various accessories. This project is in coordination with additional Wi-Fi access in front of City Hall on Jay Street that is also available for residents and visitors to the city.
MeshNetworkAlthea.jpg Connecting Rural School Children for Distance Learning
As the SARS-COV-2 virus spreads, and communities work to minimize COVID-19 cases, schools are closing and we expect all school physical facilities will remain closed for some period of time during this emergency. This will affect more than 76 million students across the US.

Many closing schools are shifting to online learning, but this transition won’t be easy. Students need three things to engage in successful distance learning; a suitable computing device, access to high-speed internet, and digital literacy.

The Covid-19 crisis has increased the need for students to distance learn and workers to telework; however, the digital divide remains as an unbridged connectivity and device gap for many. Devices such as mobile devices, notebook computers must be in place or issued that can connect wirelessly to Wi-Fi for distance learning and teleworking. Some local governments and companies have made progress through publishing online and through physical postings to map these sites. Other local governments may be further ahead in advanced connectivity having deployed wireless connectivity delivery systems that can easily scale to more locations such as parked vehicles with Wi-Fi equipment.

PublicWiFiList.jpg Open Wi-Fi Maps and Lists (by US state)
States are compiling lists of open Wi-Fi access points for residents who do not have home broadband access. While accessing these sites may be in violation of social distancing and shelter-in-place directives, some people may choose to use this option.

Open Wi-Fi SSIDs are potentially a security risk to users. Use of VPNs and secure website is highly recommended.

JVSV Distance Learning Telemedicine High Level 16Apr2020 Release.pdf Wireless Networks for Rural Distance Learning Telemedicine and Digital Inclusion
Most U.S. states have ordered residents to shelter-in-place in response to the SARS-CoV-2 pandemic. This presents significant challenges for residents in areas with poor or no broadband service, preventing them from using the internet to access distance learning resources, contact health care providers while remaining sheltered, accessing online shopping, and other online activities that most people take for granted.

Residents need three things to overcome digital inclusion gaps: a suitable computing device, high-speed internet, and digital literacy. People with Access & Functional Needs (AFNs) cannot easily overcome the digital inclusion challenge without assistance from local governments, telecommunication providers, and corporate partners. Some AFN communities are attempting to creatively solve the connectivity challenge by retrofitting school buses and “Bookmobiles” with Wi-Fi equipment and then parking them in neighborhoods with AFN residents. In some cases, schools and public libraries are petitioning the Federal Communications Commission (FCC) to waive some E-rate rules so they can open up their networks to the surrounding community. There are some significant downsides to this approach:

  • Wi-Fi coverage is limited to coverage of about 200 feet.
  • Wi-Fi signals are less likely to penetrate walls and windows.
  • It encourages people to gather near the hotspot & ignore social distancing.

An alternative that can provide broadband service to AFN residents in areas that are unserved or underserved by existing telecommunication networks is to enhance the 4G LTE infrastructure to provide additional coverage – specifically indoor coverage – to a broader range of locations, by building temporary wireless sites near the areas of need. Once the sites are in place, government or community groups can provide AFN residents with a hotspot, or an inexpensive smartphone to be used as a Wi-Fi hotspot. There are various configurations possible to provide broadband service to the largest number of AFN residents while keeping costs low, utilizing available equipment, and operating within legal and regulatory constraints:

  • COWs, COLTs, RDSs, with local fiber backhaul
  • Aerostat for coverage, with local fiber backhaul
  • COWs/COLTs/RDSs, with Aerostat-based backhaul
  • Aerostat for coverage, with wireless backhaul

This concept paper Wireless Networks for Distance Learning details each of these configurations, examines the pros and cons of each method, and explores funding options.

We thank them for their contribution.
NYKiosk.jpg Case Studies
This chapter section will feature several real-world case studies provided by the Public Wi-Fi SuperCluster Leadership team. Cities have achieved economic development, digital inclusion, emergency communications, rural connectivity, tourist attractions, and much more.
ChapterInnovationCities.jpg Case Study Summary Findings & Discussion
During the development of this Blueprint, the authorship team conducted a series of case study

interviews of local government agencies in the United States and Canada known to have deployed IoT networks. The team spoke with the cities of San Diego; San Leandro, CA; Calgary, AB Canada; and the County of San Mateo, CA. Below is a summary of the key findings from these case studies.

ChapterDeployment.jpg Considerations for Deploying Municipal IoT
Perhaps the most fundamental decision government agencies will make regarding IoT networks

is how the IoT network will be built and what the business model and ownership structure will be. The current consensus is that there will likely be two primary paths for IoT network deployments, with a third, less ubiquitous option serving as a “catch-all” classification for anything that does not squarely fit within the first two.

FundingChapter.jpg Funding Models
Three primary business models clearly emerge for today’s Public Wi-Fi projects.
PublicWiFiChapter.jpg History of Public WiFi
The dreams and aspirations of a municipal Wi-Fi system aren’t new: provide free, high-speed internet to your community, close the digital divide, shrink the homework gap, and give consumers a free, public option for internet service. It’s not hard to see why the concept has remained so popular over the years.
DCMetroDisplay.jpg Impacts to Municipal Governments of IoT Networks
The Municipal IoT will probably have numerous impacts to state and local government agencies and their operations. In a sense, this is the heart of this Blueprint paper, and the essential reason for its existence. IoT networks have the potential to improve greatly the way we deliver services, reduce operating costs, improve the economy and commerce, promote better environmental stewardship, and provide opportunities for digital equity and access – leading to developments in tourism, breakthroughs in transportation and transit, and so much more. While this list of potential use cases is by no means exhaustive, it provides an introduction for government leaders as to what they should start looking for when it comes to the potential impacts of IoT networks.
IoTChapter.jpg Internet of Things Blueprint
The scope of this Blueprint will be on the IoT networks themselves – the physical and logical layers, not necessarily the software applications and data generated therefrom.
WiFiUseCase.jpg Introduction to Public WI-FI Use Cases
Public Wi-Fi has a large number of use cases. This section seeks to provide guidance and information related to the most prominent types and will provide a general overview of the most frequently cited use cases for implementing Public Wi-Fi.
LegalChapter.jpg Legal Issues
Municipalities should be prepared to investigate legal issues that could impact their Public Wi-Fi project.

This document is not intended as a substitute for legal advice. Issues from our perspective will be classified below in terms of 1) the Regulatory Landscape and 2) Organizational Responsibilities.

OutreachChapter.jpg Marketing & Outreach
Municipalities tend to have standard channels of communicating news and project information to their constituents. Most often this includes public announcements, meetings, and eventually a press release.
