5 Essentials for High Density Wireless LAN

Introduction:  

Its all about how well you design your wifi in the initial stage of Wlan life cycle. How much time spent on the Wireless design.

1.High Signal Strength
2.High client Data Rate.
3.Disable legacy client(802.11b/g) /disable low data rate.
4.Maximum Spectrum usage and min overhead
*(Use 5ghz)

*Reduce channel overlap by strategic AP placement :Room based AP placement(mim CCI)

*Reduce extra ssids

gh

5.You need to calculate the capacity(Atleast 2-3 years from tr)
*No of clients.
*Distribution of clients(wr located)
*client types
*clients pipe i.e, special stream:mimo
*Application need

Basic RF Fundamentals

RF Basics:

•Frequencies(Specific location in RF space):How often an RF wave cycles per sec
•Waves(Actual medium we manipulate to send Data) components includes: Wavelength, Amplitude, Phase(in/out).
•Radios(The radio do the job of transmitting and receiving data).
–Wavelength=360* movment of an RF wave
–Amplitude=powerleve of an RF frame
–Phase=The relationship between two signal based on when their alternate current raising and falling.
–Frequency=Number of wavelength in Sec.
 

•Five RF Fundamental

                  -Channel
                   -Behaviours
                   -Measurements
                   -Interference
                   -Analysis

Channel:2.4Ghz

 
2.4–>Lower Frequency (2.4 billion cycle/sec)

 Channel:5 Ghz

 
                            –5Ghz for wlan is divided into UNII band 1,2,3
                            –ISM band is now added in UNII band 3
                            –Channel 169 is a 20mhz only channel.
                            –Channel 144 is just got added, no not much devices are using that.
  

 RF Behaviour:

                                     
                                –Behavior of RF defers based on the surface it impacts with.
                                –Reflection ,Absorption,Scattering,Refraction,Diffraction.
                                –Reflection and Absorption converts the RF into heat.
                                –These RF behavioral changes are taken advantage in N and AC networks                                      because of MIMO technologies.
 

   RF Measurements:

                          –Inorder to connect at higher MCS rate the device needs to operate in higher                                QAM
                          –Device to operate at 64 and 254 QAM, it needs to get connected at high SNR

  RF Interference:

                            –When an external modulated or Un-modulated RF influences affect the                                        ability of the RF receiver is called RF interference
                            –Interference happens at the receiver
                            –Low duty cycle interference can be tolerated.
                            –High duty cycle interference can wreak havoc on the channel

  RF Analysis :

                        
                       –We have different type of interference and the non Wifi interference are the                                ones which stays unknown mostly in our network.
                       –We have Tools which should be able to help you in finding out the wifi and                                   non wifi interference in you network.
                                   Tools for spectrum analysis and Site survey:
                                           AirMagnet Wi-Fi spectrum XT
                                           Ekahau Site Survey pro with planner
                                           metageek wispy DBX with channalyzer pro
                                           Metageek inSSIDer
                                           Xirrus WI-FI Inspector

Introduction to Wireless Local Area Network

Wireless Network:

A  wireless local-area network (LAN) uses radio waves to connect devices such as laptops to the Internet and to your business network and its applications. When you connect a laptop to a WiFi hotspot at a cafe, hotel, airport lounge, or other public place, you’re connecting to that business’s wireless network.

•Why WLAN?
•Mobility
▫Increases working efficiency and productivity.
▫Roaming support: extended on-line times
-> universal access & seamless services
•No new wiring and installation on difficult-to-wire areas
▫Offices, public places, and homes
▫Factories, vehicles, roads, and railroads
•Reduced installation time
▫No cabling time
▫Easy setup

How are Wireless LANs (WLANs) Similar to (wired) LANs?
