Exam 350-401 topic 1 question 483 discussion

In real life you would do a site survey :-)

Doesnt A feel like the better choice for this?

i will go with D i would say A and D both serve the requirements. problem with A: Hallways are not mentioned in A. if we apply A in real life without covering the Hallways with APs, the wireless network will be poor outside classrooms especially since we are using 5Ghz, at the same time locating will be easier since we can detect the classroom of the client very easy, with less accurate location in hallways.

https://www.cisco.com/web/offer/emear/38586/images/Presentations/P7.pdf so I would choose D

A - seems to be a solid approach. D - setting AP's to exterior walls is a No-No

Selected Answer: A Although six APs with a minimum data rate of 2 Mbps might adequately service an area, it might take twice as many APs to support a minimum data rate of 5 Mbps. https://www.cisco.com/en/US/docs/solutions/Enterprise/Mobility/emob30dg/RFDesign.html

I would choose A, it is much better design than D.

For a location management deployment, the APs are laid out in a staggered pattern. Figure 3-5 shows a typical pattern. The staggered pattern allows for more accurate estimation of the location of a device. https://www.cisco.com/en/US/docs/solutions/Enterprise/Mobility/emob30dg/RFDesign.html

I think D will have better location.

I'm going with D because that seems to be the best design for triangulation.

I go with A, because we're are dealing w/ 5Ghz

I am leaning towards F because it says: ... and fill in the center area with a staggered pattern. So you have the AP's near the wall and ALSO in the center.

I can't find an official Cisco source but the design best practice methods listed here "https://wlanprofessionals.com/wireless-design-principles-and-best-practices/" would suggest D. "If deploying Real Time Location System (RTLS), remember the AP placement differs from a data or voice WLANs. With RTLS grade wireless, APs are to be installed within and in the perimeters of the coverage area to form a triangulation pattern. A client device must be heard by at least 3 nearby APs to calculate an accurate location. The more APs hearing a client the better for accuracy and redundancy purposes."

I'm going with A. It's just stupid to install WAPs right next to a wall.

We need location, APs must be placed aroung the perimeter

But, lets be honest: One in the center of each classroom is SO much easier deployment, and for location tracking, you know what classroom it is in, so just walk down there and stand in the doorway - you will see who the 'naughty' client is in 2 seconds !

I have seen this at many conferences and webinars - If triangulation is an important factor: line the perimeter with APs (with flat panel antennas). In fact next time you are at Cisco Live, you will see this design all around the perimeter of the venue...
