So you want to design a Wireless Network
Most people’s experience of wireless is consumer -based
• Go to the local “big box” store
• Buy a wireless router
• Bring it home
• Plug it in
• Voila! It just “works”
• That’s fine for your 2,000 square foot 3 BR / 2 BA home, but things are different if your “house” is75,000 square feet and routinely has 6,000 kids over every day who all need network services at thesame time (typical Midwestern High School)
• Large-scale wireless networking is unavoidably more complex than the typical consumer experience

So you want to design a Wireless Network
WiFi is a largely misunderstood technology
• If you will likely need tens, if not hundreds, of APs to provide a decent signal in all the places peopleare likely to want a wireless connection and expected to support several hundred guests wanting touse it at the same time it’s a question of scale, just like it’s one thing to buy a small SOHO router witha few integrated LAN ports and another thing entirely to build out an effective Campus LAN or amultinational enterprise Wide Area Network (WAN) to connect several tens of large Campus LANs.
Shared communications channel• The first thing to understand is the key high-level differences in the media. Radio Frequency (RF) is,
by its very nature, a shared media channel (all receivers on the frequency within reception range can’ , -
duplex (I talk, you talk, I talk, etc. as there can only one transmitter on the frequency at a time). In thatway, Wireless LANs are very much like Wired LANs based on hubs .

• A Wi-Fi connection is composed of two simplexradio links, AP->Client and Client->AP
• Each radio link is composed of:
− Transmitter
− Cable between transmitter and transmit
− Transmit antenna− Distance between transmit and receive
antennae

− Receiver

• Access Points (APs) typically have both higher maximum transmit power levels and greater receive
sensitivity than WiFi clients, particularly BYOD class devices.
• WiFi uses two different Radio Frequency spectra or “bands,” 2.4 GHz (802.11b/g/n) and 5 GHz(802.11a/n).
• Free Space Loss, or how much the signal strength will attenuate over a given distance, is different forthe two frequency bands

• With approximately 6 dB greater loss over the same distances, 5 GHz-based signals provide about
one-fourth the coverage area as 2.4 GHz-based signals do (in wide-open spaces with no
• 5 GHz-based signals are also often more severely impacted by the Fresnel zone encroachmentsthan 2.4 GHz-based signals.
− Fresnel Zone -The area around the visual line-of-sight between a radio transmitter and receiver.Since radio waves disperse as they move away from a transmitter, obstructions in the Fresnel
zone, such as buildings and trees, will attenuate or reflect the signal, such that the intendedreceiver may not collect an adequate radio signal for reliable communication.

• There’s not much published research on the absorption of RF energy at different frequencies by
different materials, but what there is for some common materials will be presented.
• The published research doesn’t cover absorption by human bodies, but as essentially mobile bodiesof water supported by metal endo-structures (calcium bones) they do have an effect.
• There is also no measured value for reinforced concrete in the published research, but it should beconsidered to be some combination of the values for:
− Red brick, Stucco, or Cinder block, and Diamond mesh (wires in glass, like in some hospital doorwindows)
− Concrete would be similar to the first three and the reinforcement metal bars would behave

So you want to design a Wireless Network-
A 130 Mbps associated data rate (802.11n 20 MHz channel) really means, conservatively, ~60
Mbps of full-duplex throughput to be shared.• Typically, the biggest factors governing performance are:
− Co-Channel Interference
− User Density
− -
− Cell Size− Flow destinations
• Co-Channel Interference is when two or more APs are usin the same radio channel and can “hear”each other, creating a combined group of associated WiFi clients on the same channel that must allcompete for air time on the common, shared radio channel. It’s a performance killer! Think of ameeting with 10 participants all waiting for a moment of silence so they can jump in and say

chance to say.
8/20/2019 Wireless Planning Fundamentals
28/54
So you want to design a Wireless Network
• User Density is a function of the Floor Plan and simply means how many users, on average and at
peak times, associate to any given AP radio• Per-User Bandwidth/Throughput Needs vary by application mix and are ideally measured, e.g. using
TCPView and Wireshark (or something similar, more on this later)
• Cell Size is essentially how big are the different colored circles
− ’ Per-User Bandwidth/Throughput Needs.
− Example: 35 students in a ~250 sq. ft classroom that each need 2 Mbps of Per-UserBandwidth/Throughput on 802.11g (2.4 GHz radio)

So you want to design a Wireless Network -
Create solution design that will meet elicited requirements given known
constraints
• Understand aggregate required applications per-user bandwidth / throughput needs and user densityin order to determine cell size (to control number of users per radio by controlling strength of signal,causing clients to associate to closest / best signal strength BSSID)
. -
Channel Interference• Assign non-overlapping 2.4 and 5 GHz channels to physically adjacent radios in the same spectra in
APs
• Turn OFF 2.4 GHz radios as needed
• Architect around non-WiFi interference sources, e.g. 2.4 GHz cordless phones, microwaves, wirelessvideo cameras, etc., that, for business reasons, could not be removed from the environment
