The CM700 uses the fastest communication technology on the market, giving it a potential bandwidth of 1.4 Gbps. If you had internet service that was compatible, you could download data at rates of up to 175 MB per second. This is enough to download an entire 4K movie in a little over 10 seconds. Will you actually see these speeds in real life? Unfortunately, that’s unlikely. However, there are several benefits to having access to this technology.
Cable modems run on a system called DOCSIS. DOCSIS is, in essence, a method of converting data into a frequency that can be transmitted over a cable line, along with many others. DOCSIS 2.0, the previous version, allowed for a maximum throughput of 42Mb/s per channel. DOCSIS 3.0 allows these channels to be ‘bonded,’ or used together as if they were one ultra-fast connection. DOCSIS 3.0 currently uses a maximum of 32 bonded channels, and the CM700 supports all of them.
The problem is that there are very few ISPs who have the bandwidth to support offering these connections to consumers. If they did, their network would be flooded beyond their ability to supply. Despite this, we still recommend getting a 32-channel modem. The reason? Channels have a tendency to become crowded. Most of the modems on the market are still using four or eight channel systems. This means that those four channels can become very crowded. With the 32-channel system, the modem is able to select any of the available channels. You can skip the crowded ones, and take advantage of whichever are the least occupied, helping you to get the best connection speed possible.
Upstream channels are a little more limited, with only 8 available. But in the consumer networking space, this is still the best on the market. If you need a faster upload speed, you’ll be better off going with business class fiber.
