How to Select

Match the product to the workload. Small professional firms with email, web, and cloud-only work are well served by Comcast’s 300 or 500 Mbps cable tiers. Cloud-first teams working with Microsoft 365, Google Workspace, and cloud-based hosted VoIP require upload headroom– fiber is the more expensive but better choice. Logistics and retail floorspace where an hour of downtime has a tangible cost should budget for LTE failover. And in Chicago’s multi-tenant buildings always quote-list rates from two providers; published pricing is rarely the bottom line.

The bottom line: The options for Chicago businesses are genuine but are specific to the building. Be sure to check your building for what is really available (cable, fiber, dedicated) before locking into a term agreement, and calculate your real monthly cost, including fees and equipment – not the advertised rate.
