Cable Internet service requires each subscriber to have a cable modem so that data signals can be received and transmitted. All of the cable companies will lease modems to their customers, but leasing is not always the most advantageous strategy to use. The money spent on leasing a modem over six months can be used to purchase a cable modem that will be functional for years to come. Netgear cable modems are quality products and worthy of consideration by all cable Internet customers.
What Is a Cable Modem?
A cable modem is a computer network component that is designed to provide two-way data communication through the coaxial cable and fiber optic networks of cable companies. These units range in size and weight and usually come in the form of a nondescript plastic box with ventilation holes and a row of LED lights on the front. The back of the cable modem includes a coaxial cable connection and an Ethernet port.
Cable modems have gone through several standards over the years. One of the first standards, developed in the 1990s, was IEEE 802.14, but before the decade had ended, it was replaced by the Data Over Cable Service Interface Specification (DOCSIS). DOCSIS version 1.0 was the first universally accepted standard for cable modems. It was developed by a consortium of cable companies and electronics manufacturers known as CableLabs. The standard has since gone through several upgrades to incorporate new advances in technology, and although many cable Internet subscribers still use DOCSIS 2.0 modems, the latest standard is DOCSIS 3.0.
Netgear is one of the largest manufacturers of computer networking equipment in the world. The company was founded in 1996 and is headquartered in San Jose, California. Netgear began as a subsidiary of Bay Networks before being purchased by Nortel, but it became a fully independent corporation in 2002. Today, Netgear operates a worldwide distribution network organized into three geographic regions: the Americas; Asia and the Pacific; and Europe and the Middle East.
Netgear manufacturers and distributes several types of networking equipment. The company is acclaimed for its wireless routers and wireless networking cards. Netgear began manufacturing modems for businesses, but the company’s selection of modems for the consumer market has always been limited. However, a loyal following in the consumer wireless market has always provided a demand for other types of networking devices, including Netgear cable modems.
Models of Netgear Cable Modems
Netgear modems are prized for their reliability and their simple yet attractive designs. Like the company’s wireless routers, they are available in black, white and gray. Both of the models of cable modems manufactured by Netgear are compliant with DOCSIS 3.0, are easy to install and provide several options for home and small-business networking, including cable telephone connectivity. The modems can be used straight out of the box, or they can be configured for specialized network platforms by experienced technicians.
Netgear Model CMD31B Cable Modem
This Netgear cable modem is compliant with both the U.S. and the European versions of DOCSIS 3.0. The advanced engineering of this device allows users to download data at rates of up to 320 megabits per second (Mbps) and upload data at rates of up to 120 Mbps. It also includes hybrid technology that allows the modem to operate on large networks using both the U.S. and European DOCSIS standards simultaneously. For cable companies that do not yet support DOCSIS 3.0, the modem is backward compatible for DOCSIS versions 1.0, 1.1 and 2.0.
The CMD31B Netgear cable modem is easy to install and requires no ongoing management by the user. With only three connections in the back for a coaxial cable, an Ethernet cable and a power source, it is virtually impossible to make mistakes during installation. This plug-and-play device is attractive and has a small form factor. It measures 6.8 inches wide by 4.6 inches deep by 1.5 inches high and weighs less than 11 ounces.
Netgear Model CMD31T Cable Modem
The model CMD31T is Netgear’s most popular cable modem. It is also compliant with DOCSIS 3.0, and it can handle uploads and downloads at speeds of up to 150 Mbps. In addition, it is compatible with all major cable providers in the United States, and the gigabit Ethernet port allows for the fastest possible wired transfers between the modem and connected devices.
Installation of the model CMD31T is fast and simple. All a user has to do is connect the cables and plug it into an electrical outlet. This model is beloved by Netgear customers because it uses the same outer casing that is used for Netgear routers. This unique design includes edged venting, and it comes with a stand so that it can be placed horizontally or vertically. It also includes front LED lights to indicate when uploads and downloads are at one-half and three-quarters of their potential. This modem measures 6.9 inches wide by 4.5 inches deep by 1.2 inches high.
