Increasing bandwidth simply means you can receive more information — i. This creates the impression of data-speed improvements but is actually a data-quantity improvement. In fact, only cable modems and other network infrastructure can increase what we perceive as internet speed. How does a modem work and what are the affects on your internet speed? Business cable modems are an essential piece of hardware for functioning Internet and data communications systems.
Finding a unit with the right capabilities is crucial to unlocking full communication capabilities, including:. Keep in mind these cable modem tips when upgrading or selecting your internet service provider or communication hardware.
Modems must be compatible with your internet service provider. Carriers typically give you a matching unit if you sign up to rent modems and routers directly from them. Both can be done by checking the DOCSIS standard release number as well as calling your provider to hear their definitive modem list.
Many internet providers advertise packages according to their max download speeds in Mbps. Typical download speeds depend on your service provider, geographic location, hardware condition, package tier type and other variables. Cable modems operate under an asynchronous delivery, meaning those upload speeds will be a fraction of the stated download speeds. Yet the nature of business operations is synchronous and relies on the constant flow of sent and received documents, data, Internet communications, cloud access and more.
Putting both upstream and downstream data on the cable television system requires two types of equipment: a cable modem on the customer end and a Cable-Modem Termination System CMTS at the cable provider's end. Between these two types of equipment, all the computer networking, security and management of Internet access over cable television is put into place. Since a single channel is capable of 30 to 40 megabits per second of total throughput, this means that users may see far better performance than is available with standard dial-up modems.
The single channel aspect, though, can also lead to the performance variance some users experience with cable modems. If you are one of the first users to connect to the Internet through a particular cable channel , then you may have nearly the entire bandwidth of the channel available for your use. As new users, especially heavy-access users, are connected to the channel, you will have to share that bandwidth, and may see your performance degrade as a result.
It is possible that, in times of heavy usage with many connected users, performance will be far below the theoretical maximums. As more people in your neighborhood subscribe to the cable modem, the amount of bandwidth available per user decreases. This means that if you and a lot of your neighbors all get online at the same time, then you will notice a significant performance hit.
The good news is that this particular performance issue can be resolved by the cable company adding a new channel and splitting the base of users. Most cable companies monitor performance regularly and add another channel when the bandwidth per user hits a certain point. An 8x4 modem, for instance, works well with Internet service plans of up to Mbps—a safe bet for the average, well-connected household.
If any of this seems confusing, think of it this way: bonded channels are most commonly referred to like lanes on a highway—the more lanes or channels , the more cars or data that can flow. ISPs typically have services divided into speed brackets based on cost—you can check out these brackets on the ISP's website, or if you're already subscribed, on your monthly bill. Here are some speed recommendations for common services:. Just 5 Mbps of bandwidth to stream Netflix doesn't sound like much—until you take an active, connected household into account.
All these numbers help determine your Wi-Fi needs, which tie directly into your modem and broadband speeds. Therefore, if your Wi-Fi speed isn't up to par, everyone using the Internet is going to have a choppy, frustrating experience. So analyze your maximum household usage, check the modem's specs before you buy to make sure it can handle your needs as well as the speed tier you subscribe to from your ISP. Lastly, make sure your Internet connection and modem are funneling all this data to your household full of connected devices through a current-generation
