Cambium Networks Municipal Network in Aurora, Colorado Goes Gigabit Speed

City of Aurora, Colorado

Venue

3^rd largest city in the State of Colorado
Various city connectivity functions were on a mix of aging radios and solutions
City had increased funds due to the CARES Act

Solution Overview

Cambium’s LINKPlanner configuration tool
60 GHz cnWave equipment
80 GHz PTP 850E links

Services

Public Safety Communications
Voice and Data
LAN extension
Video applications
Credit Card processing
Connecting Parks and Sports Arenas

Problem

The City of Aurora was given Coronavirus Aid, Relief, and Economic Security (CARES) Act funding through Arapahoe County, Colorado. This funding was allocated to improving the IT infrastructure of the City, and the task became how to utilize it in an effective manner. 31 aging links were identified throughout the city that would be upgraded as they were under an unlicensed 5Ghz solution that currently presented reliability and capacity concerns. These concerns are increased as COVID changed various aspects of life, including increased credit card payments, or adequate distancing during school shutdowns

Project Details

17x 60GHz cnWave links, comprised of 4 cnWave V5000 Distribution Nodes (DN) and 26 cnWave V3000 High-Gain Client Nodes
14x PTP 850E Links
Planning completed with Cambium’s LINKPlanner configuration tool

Solution

The plan was to make use of the available spectrum and minimize total RF license costs by deploying a mix of licensed millimeter wave where required and using the unlicensed spectrum where available. The Cambium’s LINKPlanner configuration tool and the online learning center’s manuals and guides were heavily referenced, and the solution of a mix of 60 GHz cnWave and 80 GHz PTP 850E equipment was chosen. The 60 GHz cnWave links would support up to 1.8 Gbps, and the 80 GHz PTP 850E radios would support 10 Gbps in conjunction to handle the high-density area. The installation in 2020 involved multiple stakeholders and city departments, but went smoothly due to all the pre-planning completed. By January of 2021, the city was able to cut traffic over from their old system to the new Cambium Networks one with a very short period of service interruption. The whole project was completed three months later in March 2021.

Outcomes

Result

Increased bandwidth is able to support the densely populated areas of the city
Public Wi-Fi, City enterprise network, and credit card processing were all enhanced
Increased encryption of the links ensured proper security of credit card payments around all city owned facilities
Learning centers were able to utilize the increased bandwidth and coverage to create better distancing during school shutdowns
Thorough planning with Cambium Networks tools created a solution that would maximize throughput while controlling costs without having to settle for a “one size fits all” alternative

Rapid Systems has been providing full-service Internet and Information Technology since 1996. To interconnect their network towers, they have been using licensed 11GHz microwave links with a capacity around 1 Gbit/s per link. In order to support their plans for expansion, they need to upgrade their links to support up to 10 Gbit/s moving forward. Rapid Systems considered E-Band as their solution, but the biggest challenge is that some of their towers exceed distances of 8 miles. Keeping the radios synchronized and deployment costs low would require an innovative solution.

The Hollinger Project was a huge undertaking as the historic mine site would have to be converted to an open pit mine. Some of the initial challenges would have to be overcoming the leftover structures of the mine, but the biggest challenge would be creating a wireless network that would be suitable for the site. While a public Wi-Fi network could suffice, there were security risks that ultimately made a private network for communications to be selected. With the security concerns noted, the next considerations would be the need for...

Since there are no cables running to the island, all connectivity is delivered through wireless means. The water reflection, tides, harsh weather, and other obstructions such as boats and trees can cause disruptions in the wireless stability on the island. The biggest issue is that during the summer months when the number of visitors surge, the island struggles to keep up with the increased demand and that poses a risk to the local systems.

Since the Public Safety DAS market is very mature with many competitors in Denver, there needs to be significant cost and feature considerations when bidding for a project as large as these two towers. One of the biggest issues with creating a competitive solution was the sheer size of the buildings, with over one million square feet to cover. Utilizing a fiber distributed DAS would be too costly and complex to cover heavy stairwells and enclosed garage spaces as well.

The SFD has been in service for over 60 years, with rapid growth and expansion within the last 20 years increasing the number of calls that need to be responded to. To ensure that the level of service is maintained, the SFD needed to upgrade its legacy microwave radio equipment that is quickly reaching end-of-life. With the 45mbps limiting operational capacity, and a new set of Public Safety Grade Systems and Facilities guidelines in 2014, the SFD needed to choose equipment that would meet their requirements.

ATSI (Advanced Technology Solutions International) was called in to assist an Egyptian gas company to replace their existing satellite communications network. The system was ineffective with frequent downtime, huge delay time and insufficient bandwidth to carry the traffic. There are also high costs associated with running the satellite communications system. Microwave link conditions were challenging due to distance, and interference due to water in the link path that can lead to inconsistent performance.
