A. B. C. D.B.
In a medical treatment environment, both data and voice services are critical, and as such, the wireless design should meet certain requirements to ensure that these services are available at all times.
One of the most important requirements for a wireless network in a medical treatment environment is reliable and consistent coverage. This means that all areas of the environment should be covered by the wireless network, and there should be no dead spots or areas where the signal is weak or non-existent.
To achieve reliable coverage, the wireless network should be designed to meet certain minimum signal strength requirements. The signal strength is usually measured in decibels (dBm), which is a unit of power relative to 1 milliwatt.
The answers provided in the question specify different levels of signal strength and coverage, so let's examine each one in detail:
A. Overlapping -72 dBm coverage from two access points: This means that there are two access points covering the same area, and the signal strength from each access point is at least -72 dBm. Overlapping coverage from two access points can help ensure that there are no dead spots or areas with weak signal strength, as the two access points can work together to provide continuous coverage.
B. Continuous -67 dBm coverage from one access point: This means that there is only one access point covering the area, and the signal strength from that access point is at least -67 dBm. While this level of signal strength is relatively strong, having only one access point means that there may be areas where the signal strength is weaker or non-existent.
C. Continuous -72 dBm coverage from one access point: This is the same as option B, but with a slightly lower signal strength requirement. As with option B, having only one access point means that there may be areas with weaker signal strength.
D. Overlapping -67 dBm coverage from two access points: This is similar to option A, but with a slightly lower signal strength requirement. Overlapping coverage from two access points can help ensure that there are no dead spots or areas with weak signal strength, as the two access points can work together to provide continuous coverage.
Given the critical nature of the services required in a medical treatment environment, it is recommended to choose the option that provides the most reliable coverage, which would be either option A or D. However, since the question only asks for the minimum requirement, the correct answer would be option C, as it specifies continuous coverage at a signal strength of -72 dBm from one access point, which is the minimum requirement for this scenario.
