Dual band antennas have lots of practical uses, especially for mobile devices. These antennas operate on two bands or frequencies (similar to radio stations) and can either work on these different frequencies one at a time or simultaneously, depending on the capabilities of the individual antenna.

The biggest advantage to dual band antennas is their ability to provide a strong, stable wireless connection  in often difficult to reach locations. For this reason they are often used in devices such as cellular or dual band wireless access points. The two most common frequencies used in these antennas are 2.4 GHz (802.11g/N) and 5.1 GHz (802.11a/N). These two “channels” have differences in terms of their abilities. The 5.1 GHz option has the higher frequency and subsequently, a smaller range. However, this higher frequency also allows the 5.1 GHz antenna to handle more information at any one time. The 2.4 GHz option inversely has a lower frequency; allowing the antenna to cover greater distances as well as penetrate surfaces more efficiently.

These factors lead to the conclusion the the 2.4 GHz option is superior for not only establishing a good, strong connection indoor where many surfaces and walls act as barriers to fully covering large ground plans, but maintaining these connections as well. Selecting the proper antenna can be very important for this reason. Some dual band antennas can use both frequencies at once. While others can switch between the two frequencies depending on which option provides a stronger connection in the given area.

Common household appliances also work these channels as well however. This can interfere with the connectivity of other technology within a home or office sometimes. However, that can occur in almost any situation where there are multiple devices operating at once. For many devices, dual band antennas are a stable, easy way to connect to the things you may need.

Making Information Organization Easy

For many businesses, public services such as schools and libraries, and industries, an Ethernet cable connection is the most dependable option in information technology.

Information is the first necessity of any business. Ethernet cable connections make the transmission of information from one location or person to another easier and faster, allowing for quick communication between workers at a business without having to pass out memos, saving both time and paper. This also allows for quick and reliable internet access that is less prone to connectivity issues and is invaluable as a resource.

Schools and libraries also benefit from Ethernet. Libraries have complex databases that have to process a variety of information: everything from patron due dates and fines, to filtering and sorting materials and locations as well as inter-library loans has to be managed by the library. Having the computers connected via Ethernet cable allows these computers to process large amounts of information at the same time, schools can also use the connectivity to have students share information throughout the classroom and post lessons and homework on it as well.

Ethernet cable can connect equipment other than just computers. There are many devices for controlling machinery or for monitoring the machinery functions that can be interconnected by Ethernet and which can be useful in spotting problems and avoiding mistakes. If a process involves timing or temperature, the equipment that measures any of these variables can be monitored easily from different locations instead of having to be checked manually one by one.

In business, industry, and for libraries and schools, whether for a class project or company deadline, time and reliability matter. An Ethernet cable connection makes sending, organizing, and accessing information easier, more affordable, and faster.
