Introduction
You will be doing a site assessment and design proposal for a wireless installation at a virtual site. This project will be done as an individual.
Case Study
The Building
A company, MyCo, has rented a two-floor office space in a commercial/industrial area measuring 132’x78′. The facility is located in Lake County, Illinois. The space is broken up into fixed wall offices and cubicles. The internal structure consists of 15′ ceilings, with a suspended ceiling dropping down to 12′ leaving a 3′ plenum above the suspension system. We have Armstrong Cortega Second Look tiles in an Armstrong Prelude XL Fireguard system. The tiles are wet-formed mineral fiber with an insulation R-factor of 1.6 and an energy absorption of 0.28 watts/sqm. The grid uses a 15/16 T-rail suspended from the support structure at 4 increments. It can support 42lbs in its current configuration per 4 segment after taking into consideration the tile and structure weight. The T-rail is recessed 1/4 into the tile.
The cubicles are selected from the Allsteel Concensys system. They are a combination of steel frames, laminate and composite horizontal surfaces and fabric covered vertical surfaces. There are small 2×2 whiteboards in use throughout the cubical areas. These are aluminum backed board with a laminate coating.
The plenum space contains a combination of flexible and non-flexible ductwork as well as a sprinkler system. It is an active plenum so all components installed in this space need to be plenum-rated. Fluorescent tube lighting fixtures are situated in regular patterns throughout the space. Ceiling tiles are replaced with 2×4 fixtures leveraging electronic ballasts fed with 240vac power.
Exterior-facing windows and doors meet energy star requirements for this area. They take advantage of low-e glass, triple pane with argon fills. Interior glass is not filmed but is tempered per local building code. Interior doors are hollow core with no metal reinforcement. The interior walls are constructed using type-C gypsum board. They are fixed to steel studs 16 on-center. Window and door casings interior to the building are painted steel.
Floors are constructed of pre-cast/pre-stressed flexicore concrete panels. The concrete panels are 12 thick.
Functional Requirements
The staff require wireless service throughout the building, but special care must be taken to cover the meeting and break rooms as these are concentrated areas of mobile users. The staff request no less than 802.11ac wave 2 infrastructure be installed. Many users will likely give up their wired connections and leverage the convenience of the new wireless network, so planning for capacity and density over simply coverage would be advantageous. You will have to carefully balance the coverage and AP density dynamics. There are currently 185 users within the space at any given time. We expect this to grow to roughly 250 users within three years. Each user can be assumed to have 2.2 devices, a mix of corporate and BYOD (e.g., company-issued laptop, personal phone and many will have another device).
Deliverables
You will need to provide markups of the provided drawing to show AP placement and coverage, channel designations on a per-AP basis, etc. Furthermore, all equipment used (APs, antennas, cables, controllers etc.) will need to be documented as a total solution to the sites request. All of this information must be included in a single cohesive document. It must be delivered electronically in a format of your choosing via the Sakai assignment tool. All deliverables must be provided no later than 11pm CDT on Thursday, April 9, 2025.
Grading
Grading will be as follows:
50pts – Floor one layout, including channels (2.4GHz, 5GHz, and 6GHz if appropriate)
50pts – Floor two layout, including channels (2.4GHz, 5GHz, and 6GHz if appropriate)
50pts – Hardware selections (APs, antennas, cables, controllers, etc.)
150pts total
