Wired and Wireless Media
Wired and wireless media both provide means of transporting data. Though both provide benefits in certain areas, neither is particularly better than the other. It is important for organizations to utilize both methods of media to maximize what benefits each provides while minimizing that same media types short comings. Anders (2010) uses six metrics to compare wireless and wired media: range, installation effort and flexibility, data volume, availability of information in room, reliability, and cost. Both types of media score evenly with each being ranked better than the other in three of the six categories. Gokhale (2005) states that half, and possibly more, of the installation costs of cable media are due to labor costs. This is because tasks such as digging ditches to run the cable must be completed according to specifications such as Telecommunications Industry Association (TIA) and the Electronics Industries Alliance (EIA) 568A/B that ensure the hardware will operate at optimal performance levels. Wireless networks still require labor such as in the erecting of towers and hotspots to propagate the wireless signals, but these overall costs are not as high when compared to wired media (Anders, 2010). Harder (2011) identifies three main types of wireless technology: Wi-Fi, ZigBee, and EnOcean. The main difference between the three is the amount of bandwidth that is provided. Gokhale (2005) defines bandwidth as a range of frequencies that can be transmitted minimal distortion (p. 37). Wi-Fi provides the most bandwidth, with ZigBee considered a mid-range, and EnOcean the lowest. One benefit of Wi-Fi and ZigBee is that they are designed to operate together with ZigBee ideal for field bus communication (Harder, 2011). When planning wireless networks indoors, Anders (2010) states that sub-gigahertz frequencies may be better than the 2.4 -ghz Wi-Fi since the lower frequencies experience less attenuation and radio interference. Gokhale (2005)...
