From a technical point of view there are two types of cable modems). You have an old, one-way cable modems that work in a standard network coaxial cables. They only offer a download speed up to 2 Mbit / sec and have virtually no possibility of transmission.
Fortunately, it is a slow, one-sided approach has been basically completed, and the chances are that this cable modem will be available is small. A new type of cable modem is a hybrid modem fiber-optic / coaxial. They include the HFC cables, which are much faster and offer the possibility of downloading and uploading .
From the point of view of the consumer, there are also two types of cable modems), both of which are hybrid models / concentric. Because the single-sided modems sold, will have to consider and decision-making. Your choice will lead to the standard cable modems or combo cable modems / routers.
Standard cable modem will provide Internet access but not at home will allow any wi-fi signal. If you have a standard cable modem and want to use wifi, you must purchase a separate wi-fi router. On the other hand, cable modem / router 2-in-1 provides access to the Internet and Wi-Fi from one device.
Each of these types has its own advantages and disadvantages. Model 2 in 1, they are more cumbersome, since you don’t need to look for space on two separate units, and allow for more precise installation, as there will be less wires, and you will only use one socket .
Model 2-in-1 also allow for a quick setup and run as you do not need to configure two separate devices. Also easier to solve. If one part of the device stops working the entire unit must be replaced, and unit combo is more expensive than replacing just the modem or the router.
Separate units allow more control over the functions. For example, thanks to a special router, you can enable the dynamic DNS or prioritize network traffic using QoS . If necessary, you can also install different firmware for your router. Dedicated routers usually provide a slightly higher speed Wi-Fi. However, for the average person combo unit can provide all you need because most people do not know how and why to use these additional features, and the increase in speed may not be noticeable.
Cable modems and DSL modems
As cable modems and DSL modems always provide a high-speed Internet access. DSL provides this through a dedicated telephone line, while cable modems provide Internet access using the shared line cable television.
Theoretically, the cable modem provides higher Internet speed , but in practice this is not always the case. Because cable networks are configured the same as the shared local area network (LAN), and many users with the same bandwidth, the actual speed can vary significantly. The more users will be online at the same time, the slower the Internet speed. It may happen that at night, when people sleep, you have fast speed Internet late at night, but in the evenings, when more and more people use the Internet, your future rate can be reduced by half .
Internet speed DSL is more consistent than cable, because each user has its own separate line, but in the best case, the speed of the Internet cable far exceeds DSL. In addition to integrity, another advantage of DSL is a higher level of security. Because don’t you provide the connection, the hacker is harder to access Your personal network. A big disadvantage of DSL is that the closeness of the Internet service provider (ISP) can significantly change the actual speed of download and upload. File transfer is much slower than loading when using a DSL connection.
Internet speed across America
Every year the Internet is growing rapidly in the United States and other countries. The average family received speed 10 Mbps in 2011, And in 2014. Catapulted to 31 Mb / s. In 2015. FCC again zdefiniowało speed broadband Internet access with a bandwidth of at least 25 Mbit / s and 3 MB / sec.
Until recently, the download speed of the modem up to 100 Mbps and a maximum of 8 MB / sec. The new version of DOCSIS 3.1 it is much increased and allows you to transfer data at speeds up to 10 Gbps and 1 Gbps upstream. Currently, however, these new gigabit speed is available only in selected areas of Atlanta, but soon will be offered in Miami, Nashville and Detroit.
The average consumer cable modem that uses advanced technology, and paying for the higher subscription plans can be expected theoretically, the speed from 150 Mbps to 250 Mbps. In practice, however, the majority of consumers will never feel such a high speed. Most people can expect 50% to 60% of the speed advertised Internet service PROVIDER on a permanent basis
