Banda is a concept with different meanings. It can be a group of armed people, a youth gang, a partiality of people who support someone or a musical group. The band, on the other hand, can also be a wide band that serves as a distinctive, a band or the interval defined according to the field of variation of a physical magnitude.
Wide or wide, from the Latin amplus, is something that is more or less wide, that has too much width or that is too wide or loose.
Some of these definitions allow us to understand the notion of broadband. This concept is used in the field of telecommunications in reference to the transmission of symmetric data that allows several packets of information to be sent simultaneously to increase the effective transmission speed.
The notion of broadband is also used to name network engineering that allows two or more signals to share the same transmission medium. A router that operates with speeds exceeding 100 Mbps is considered to be broadband since it allows obtaining symmetrical transmission speeds.
The speed involved in a broadband connection has increased over the years. From the 256 Kb / s provided by ADSL connections, technologies that offer 100 MB / s or more have been switched.
Today the idea of broadband encompasses several notions that transcend the connection itself. Thanks to the fact that these types of connections allow you to surf the Internet at high speed, broadband is associated with issues such as digitization and interactivity.
Types of broadband
Today’s market offers a wide variety of broadband Internet connections, although this does not mean that all alternatives are suitable for every customer; on the contrary, it is an area in which it is usually easy to find the ideal offer for each user. Some of the main variables are the connection technology, the maximum speeds (both download and upload) and the traffic limits imposed by the provider companies.
Let’s look at two of the most common types of broadband today:
ADSL
The acronym stems from the fusion between the term “asymmetric” and the acronym of a previous technology, DSL (“Digital Subscriber Line” or “Digital Subscriber Line”), which offered a maximum speed of 160Kbps in both directions and covered distances of 5,400 meters. However, ADSL exceeds this speed dozens of times, and is currently offered in two classes:
* ADSL 1, until the end of the first decade of 2000 was the most common. It reached a maximum download speed of 2Mbps (2048Kbps, to compare it with DSL) and 1Mbps upload;
* ADSL 2+, the most popular at present, with speeds reaching 20Mbps downstream and 1Mbps upstream. It is worth mentioning that the technology used by ADSL 2+ allows the data transmission speed to be adapted to the distance between the customer and the switchboard, as well as the state of the line.
Satellite
This type of broadband is designed for those who live in areas without cable service coverage, such as ADSL. It is an asymmetric connection, with download speeds higher than 20Mbps, but with three points against quite marked: the price, well above cable services; the traffic limit, which forces customers to take care of their daily consumption, turning spontaneous and carefree browsing into a potential problem; the latency, so higher than that of an ADSL connection that it prevents activities such as playing online.
