Among the comparatively new technologies that offer high-speed wireless internet and access to data system over an extensive region is Wireless Broadband. “Broadband”, in accordance with the 802.16-2004 standards, means its immediate bandwidth is greater than about 1 MHz and it supports data rates greater than around 1.5 Mbits/s. From this, it can be said that Wireless Broadband speeds are more or less comparable to wired broadband access like those of a DSL or cable modem.
Dial-up modems are restricted by a bitrate of fewer than 56kbit/s (kilobits per second) and this also means the out-and-out use of telephone line. Compared to this wired requirement with dial-up modems or DSL, wireless broadband can function without needing to connect through the telephone line (no need for telephone use to be sacrificed during internet use) and can even supply greater data at a faster in fact, double the rate.
There have been a variety of minimum bandwidths that have been utilized in order to define the capacity of broadband technology. This selection ranges from about 64kbit/s to about 4.0 Mbit/s. In 2006, broadband was reported (2006 OECD report) to have a defining rate of download and data transfer that is almost equivalent to or greater than 256kbit/s. As of 2010, the United States Federal Communications Commission (FCC) has delineated “Basic Broadband” rates of data transmission to about 4 Mbps (megabits per second) in the very least, or 4,000,000 bits per second for downloading or downstream (meaning it is coming from the Internet and downloaded by the client). Upload (also called ‘upstream’ meaning information transmitted from the client’s computer to the internet) speed is defined to be about 1Mbps.
Instead of the use of telephone wires, Wireless broadband technology use radio waves as the medium for transmitting information. However, the problem with radio waves are that the farther you are from the main source or transmitter (the central hub or server, which broadcasts the wireless internet connection), the more distorted the signal becomes and transfer of information will become slower and inconvenient.
In cases like this, providers of broadband wireless internet access set up in a specific area which is then called the “hot spot” where people can gather and try to access a sure connection to the system.
Another problem with this technology too though, is that since it makes use of radio waves, the signal can be transmitted to anyone who happens to be within the wireless internet signal’s radius. Sometimes, unwelcome users can use up extra bandwidth that may slow down network traffic and cause other serious problems. If there are for example unknown users who are able to use your connection without your permission and they download illegal material or commit crimes online, these could point back to you once investigated.
For these particular cases, wireless broadband access has been installed with passwords and firewalls in order to protect the connection that is used by private networks. In order to make sure that unauthorized persons will not be able to connect to the wireless network, the password request will either give or deny access to the client that can detect the signal. Especially for home users, it is advised that they have their broadband wireless internet installed with the proper security measures.
There other areas that offer broadband wireless internet services like internet cafes and other public “hot spot” areas. Places like these usually require a fee before a client can be allowed to gain access of the wireless internet service. In other cities though, wireless broadband technology has been made part of the community as a courtesy to their residents. This wireless internet service has been installed in order to make access free for the public. As long as you know the right areas or “hot spots” where you can bring your Wi-Fi capable equipment, then you’ll be good to go.
