What Buyers Should Consider When Shopping For Docsis 3.1 Modems

What Is Docsis Modem?

Abbreviated as Data Over Cable Service Interface Specification, the Docsis technology efficiently transfers data through coaxial cables. The technology delivers impressive speed and reliability—the reason it’s widely reputed over other cable operators.

The speed at which the Docsis technology delivers internet, video, and voice services on TV cable systems is superbly incredible. It’s loved among heavy internet users because of the quality of its connection and the security it offers during the internet transfers.

  • Upstream and Downstream Channels 

Most Docsis 3.1 modems have 32 or 8 downstream channels and 8 or 4 upstream channels. The total number of channels a modem dictates the speed at which it can download data. In all instances, the downstream channels are way more than the upstream channels. Gamers want a modem that can deliver optimal downstream speeds and so they are always looking for modems that can provide superior performance when playing virtual reality games at super-bright 4K speeds.

  • The Docsis Protocol 

Most modern modems use either Docsis 3.0 or 3.1 protocols. The two protocols are uniquely different in terms of specifications, speed, and channel numbers. If your preferred internet service provider offers high internet speeds of up to 1Gbps or higher, you should opt for modems with Docsis 3.1. In case your service provider offers a lower speed, you should go for Docsis 3.0.

The average internet speed in most States is capped at 66Mbps, and so it’s quite lower than the average offered by the Docsis 3.0 modem. That said, consider getting the modems with the Docsis 3.0 protocol instead of the 3.1 protocol.

  • The Upload and Download Speed 

The download and upload speeds determine how seamless and smooth your gaming experiences will be. The speed rating in most modems talks about the download speed. In other words, it talks about the no of megabits data you can pull from the service provider during your gaming experiences.

It’s crucial to understand that getting modems with high-speed rating doesn’t mean you will enjoy promising and impressive speeds if your ISP cannot provide such speeds. Don’t struggle to search for high-speed modems if your internet provider cannot give the exact speeds.

  • IPS Compatibility 

The compatibility of the modem to the IPS used by your internet service provider is another consideration. Not every modem available is compatible with every type of service provider. The majority of modems available are only compatible with cable internet service providers.

Look for modems that have firmware updates to allow for easy compatibility with different modem providers. You can check the compatibility of any modem by browsing through the official site of the provider or searching through Google.
