What equipment do I need for Quantum Fiber business internet?

For Quantum Fiber business internet, all it takes to harness the massive potential of fiber-optic internet is a simple Wi-Fi pod that hooks up just like a residential router. Want to extend your Wi-Fi networking signal or add a VoIP plan? You can also order extra Wi-Fi pods or headsets/handsets. Call 1-833-599-2450 now to learn about your options.

How long does the installation of Quantum Fiber for business take?

For most small businesses, Quantum Fiber installation takes up to 3 hours so your technician has enough time to wire a fiber-optic line to your building (if that hasn’t been done already), then drill and install what’s called an optical network terminal to bring the exterior line indoors. Once they set up your new small-business fiber internet network, they’ll leave you to it—and you can start racking up sales.

Does "unlimited data" really mean no overage fees?

Yes, it really means no overage fees, and more benefits besides. With Quantum Fiber business internet, unlimited data means there’s no meter running on your data use—so there are no extra fees and no speed throttling once you use a certain amount. Run all the virtual meetings, cloud tools, and system backups you want with total freedom.

What is the difference between up to 940 Mbps and up to 2 Gig business internet?

Business internet up to 940 Mbps supports everyday operations like video calls, cloud apps, and transactions for a staff of about three or more daily users. Business internet up to 2 Gig is better suited for larger teams, more cloud tools and system backups, and more connected devices, especially if you also run a guest WiFi network.

Why should my business upgrade to up to 2 Gig fiber internet?

For small businesses with a staff of about five or more users, up to 2 Gig internet allows smooth multitasking, fast file transfers, and excellent performance for HD video conferencing and cloud platforms. For even smaller businesses, up to 2 Gigsis still a great option if you want room to grow.
