Wireless Basics

(ITC, Mayo Clinic)


Wireless technology is used in many types of communication. There are many advantages associated with installing a wireless network compared to a wired network such as mobility, cost-effectiveness and adaptability. 

"The widespread availability and demand for multimedia capable devices and multimedia content have fueled the need for high-speed wireless connectivity beyond the capabilities of existing commercial standards. While fiber optic data transfer links can provide multigigabit- per-second data rates, cost and deployment are often prohibitive in many applications. Wireless links, on the contrary, can provide a cost-effective fiber alternative to interconnect the outlining areas beyond the reach of the fiber rollout. With this in mind, the ever increasing demand for multi-gigabit wireless applications, fiber segment replacement mobile backhauling and aggregation, and covering the last mile have posed enormous challenges for next generation wireless technologies. In particular, the unbalanced temporal and geographical variations of spectrum usage along with the rapid proliferation of bandwidth- hungry mobile applications, such as video streaming with high definition television (HDTV) and ultra-high definition video (UHDV), have inspired millimeter-wave (mmWave) communications as a promising technology to alleviate the pressure of scarce spectrum resources for fifth generation (5G) mobile broadband." -- [IEEE]

While wireless networks can be just as fast and powerful as wired networks, they do have some drawbacks. For example, wireless networks have limited bandwidth. It can also be a security risk if not installed and maintained properly. Wireless networks also have an increased chance of jamming and interference due to external factors such as fog and dust storms or when a flying object such as an aeroplane passes over the field. When too many people in the same area use wireless networks, the band of air that they transmit signals on can become overloaded.
