7 Wi-Fi BASICS RF: The Invisible Beast Interference Crowding effect Coverage holes Radiation blindness Path heterogeneity
8 11 Mbps 1999: 802.11b WIFI BASICS Wi-Fi Evolution 54 Mbps 2003: 802.11g Every 4-5 years there is a new standard available in the market 300 Mbps 2009: 802.11n Wi-Fi speed has seen growth of approx. 5X increase in the speed Current generation of Wi-Fi has broken the Gigabit barrier > 1Gbps 2012: 802.11ac
9 Wi-Fi BASICS Frequency Wi-Fi operates in two different frequency bands 2.4 GHz Band : Total 11 channels, only 3 nonoverlapping channels 5 GHZ Band: Divided into three sub-bands - U-NII 1 - U-NII 2 & U-NII 2 Extended - U-NII 3 25+ channels available
10 Wi-Fi BASICS Frequency
11 Wi-Fi BASICS Interference Three types of interference Co-channel Cross-channel AP1 AP3 AP2 AP1 AP2 Microwave AP1 Cameras Bluetooth Non-WiFi CO-CHANNEL CROSS-CHANNEL NON-WIFI
12 Wi-Fi BASICS Interference- 2.4GHz 5 MHZ CHAN 1 CHAN 2
13 Wi-Fi BASICS Interference- 2.4GHz 10 MHZ CHAN 1 CHAN 3
14 Wi-Fi BASICS Interference- 2.4GHz 25 MHZ CHAN 1 CHAN 6
15 Wi-Fi BASICS Interference- 5GHz 20 MHZ CHAN 36 CHAN 40
16 Wi-Fi BASICS MIMO Reception of signal via multiple path was considered bad for wireless technology MIMO technology enabled constructive use of signal from multiple paths It uses multiple transmitter antenna to transmit multiple streams simultaneously Requires multiple antennas at the receiver to decode multiple streams
17 Wi-Fi BASICS Which is better- 2x2, 3x3, 4x4 or higher? The more the better.but Most of battery powered devices such as smartphones support 1x1 MIMO Most laptops and tablets come with 2x2 MIMO support Public Hotspot SMB Enterprise 2x2 MIMO 2x2 MIMO 2x2 or more Dual radio Dual radio Dual radio or more 11n or 11ac 11ac or more 11ac Wave2 750 Mbps 1200 Mbps 2.1 Gbps
18 Wi-Fi BASICS Speed vs Range 6Mbps Link speed decreases as the distance between AP and client increases The lowest possible speed at which client can connect is 6Mbps Total throughput that a user gets depend on the link speed 75 Mbps 150 Mbps 300 Mbps
19 Wi-Fi BASICS Crowding One AP is fully loaded while other AP has no load Often happens in dense user environment- Enterprises, conferences etc. AP 1 < 5 Users AP 2 > 20 Users AP doesn t support load balancing Degrades performance of the network drastically
20 Wi-Fi BASICS Coverage Holes In a typical office or indoor environment, difficult to visualize coverage problem Manual site survey can also be done to discover it but not practical always Requires automated software tool to discover potential coverage holes
21 Wi-Fi BASICS Radiation Blindness Enterprise grade APs come with optimized antenna to provide good coverage Ceiling mount APs have better coverage in horizontal plane Use of ceiling mount APs on a wall, or tilting external antenna are examples which create performance problem
22 Wi-Fi BASICS Path Heterogeneity 30 dbm, EIRP=36dBM 20 dbm, EIRP=22dBM
23 Wi-Fi BASICS Path Heterogeneity HIGH RANGE More signal bars doesn t mean you can connect Happens more with mobile devices-they are not designed to transmit at very high power Range claim done by most vendor fall flat in connectivity test MEDIUM RANGE LOW RANGE Range factors-distance, Speed, Noise, LOS
