1. Investigate the differences between 802.11a,b, g, n, ac, ad, af, ah, and ax technologies. What are their wavelength(s), ranges, speeds, kinds and numbers of antennas, bandwidth, etc. Which ones use MIMO? And what is MIMO anyway? Write a paragraph explaining each one, and finally provide a summary table that will aid in comparison between them.

2. Your client has asked you to recommend routers you would buy with budgets of, respectively, $100, $250 and $500. Write a report giving a recommendation for each budget, and justifying your recommendations by comparing them with other options within the price limit. You should also include a summary table highlighting the differences between the three different options that you have recommended. Be sure to be clear about which 802.11 standards each of your recommendations implements. (You will need to explore commercial websites or shops to find out what is available, and at what price. Be sure to cite in your references where you found the details about the routers you recommend, where you would purchase them, and what the supplier is charging for them.)
