The main advantage of WiMAX is that it allows high-speed wireless Internet connections over a broad coverage area, while the main disadvantage is that it is expensive to install. Companies and municipalities set up WiMAX networks to provide home or mobile Internet access throughout an entire city or county.Know More
Worldwide Interoperability for Microwave Access governs wireless communications. Because it covers a broad area, WiMAX provides Internet access to remote areas that cannot be serviced by other broadband services. As a wireless technology, it can provide high-speed connections for a variety of devices, including cell phones and computers.
WiMAX can provide wireless service in two ways; each way has advantages and disadvantages. One type of WiMAX requires a line-of-sight connection, which means that a fixed-dish antenna must have access to a WiMAX tower that is clear of obstructions such as trees and buildings. A line-of-sight connection can be difficult in certain places, such as a heavily wooded area. However, line-of-sight transmissions use high radio frequencies, which have little interference and a high capacity for exchanging data. Another type of WiMAX does not require a line-of-sight service but allows a small antenna on a computer to connect to a WiMAX tower. The disadvantage of this type of WiMAX is that it uses a lower frequency range, which involves more interference and less capacity.Learn more about Internet & Networking
Multimedia sources make communication and learning easier for people all over the world, but it can be expensive to create and difficult to configure. For most people, multimedia is easy to understand and convenient to use, and making presentations is simpler because a single multimedia source can be used to convey a message or concept in different ways to an audience. However, some forms of multimedia are incompatible with the hardware and software that a person or entity has. In addition, it may take significant resources, manpower and skill to create multimedia forms.Full Answer >
There are advantages and disadvantages to using both primary and secondary sources of data in business, including the advantage of being able to frame the collection process and the disadvantage of expense. Using secondary data someone else has collected is often free, but it is sometimes difficult to place it within the context of the research.Full Answer >
An advantage of frame relay is that is often cheaper than dedicated lines. Less hardware is required for the same number of connections, and traffic bursts are also buffered. Disadvantages of frame relay include possible traffic jams and short-term drawbacks with feasibility.Full Answer >
Instant messaging is convenient and more cost effective than traditional forms of communication; however, instant messaging can pose a security risk, allowing viruses to damage the computer and the network. Additionally, instant messaging has the potential to compromise the security of sensitive information.Full Answer >
