Steve, an entrepreneur, is setting up his Internet startup company on a small farm in a rural area to take advantage of the low power costs. The office building is a rectangular area that diagonally measures 60 meters. Steve plans to install a central wireless router that can provide Internet access from any point inside the office. The business operation requires high Internet speeds in the range of 100-150 Mb/s. Which of the following wireless standards would best serve Steve's requirements?
A) 802.11a.
B) 802.11n.
C) 802.11b.
D) 802.11g.

The following wireless standards would best serve Steve's requirements is B) 802.11n

Explanation:

802.11n is a specification for wireless communications. A 802.11n Wi-Fi network connection supports up to 300 Mbps of rated theoretical bandwidth under best case conditions. But in general, 802.11n will report connections in the 130-150 Mbps rated range. Steve requires high internet speeds in the range of 100-150 Mbps. So the wireless standards which would best serve Steve's requirements would be 802.11n.

B) 802.11n

Explanation:

The difference between Wifi standards is mostly given by the speed connections that they allow. They are all basically evolutions of the same product but with different speeds and ranges:

All options are already considered obsolete since the current standard is 802.11ac (2013) which supports higher speeds (including 5g), and this standard has already been replaced in many parts by 802.11ax.

Out of the 4 options given, 802.11n has the longest indoor range with up to 70 meters, all the other standards have much lower ranges: a and b have a maximum indoor range of 35 meters, and g's indoor range is 38 meters. N standard also supports higher speeds than the other 3 and can support dual bands (i.e. normal and fast wifi).

dual credit courses allow you to take a test at the end of the course that, if you pass it with a high enough score, will give you college credit.

rational decision making is a multi-step process for making choices between alternatives. the process of rational decision making favors logic, objectivity, and analysis over subjectivity and insight. the word “rational” in this context does not mean sane or clear-headed as it does in the colloquial sense.
