The ongoing evolution of free space optics can be grouped in two fronts, those driven by prevailing commercial interests and those that are at the forefront of the cutting edge of the technology, driven by military interests. The commercial front of FSO technology is primarily limited to a set of vendors introducing slightly higher-capacity and lower-cost products, each trying to differentiate from the other. Since commercially available technology already achieves gigabit per second and more bandwidth, meeting or exceeding bandwidth needs of most of the applications, developments in the commercial front have mostly been on cost reduction rather than performance enhancements. Perhaps the only deviation from this general trend has been the mesh networking approach where FSO technology is taken from being a point-to-point link technology to a mesh networking technology. The dominant portion of development at the cutting edge of FSO technology has been occurring at military and university laboratories. There have been significant efforts and development on optical technologies to overcome atmospheric effects such as fog and clouds by means of techniques such as famto-second pulses. Efforts have also been made on developing highly sensitive detectors such as photon-counting detectors. University labs have also conducted research efforts on networking aspects of FSO technology. Some of these developments are likely to make their way to commercial applications soon, while the others, though they may take much longer time to become commercially viable, are bound to have a lasting impact on the wireless communication technology landscape.

Only the positive value has meaning so take t = 0.68 weeks for the zero slope condition and calculate P

The following Self Test questions will help you measure your understanding of the material presented in this chapter. Read all the choices carefully, as there may be more than one correct answer. Choose all correct answers for each question.

Address Resolution Protocol (ARP)

places into m the memory address of the variable count. This address is the computer s internal location of the variable. It has nothing to do with the value of count. The operation of the & can be remembered as returning the the address of. Therefore, the preceding assignment statement could be read as m receives the address of count. To better understand the preceding assignment, assume the variable count resides at memory location 2000. Also assume that count has a value of 100. After this assignment, m will have the value 2000.
