Fast Roaming and Multi-WAP Environments (2016)

Note:

• AC - 5GHz only
• Channel Bonding: Combining channels (i.e. width of highway lanes)
• Higher channel bonding increases speed but increases chance of interference
• MU-MIMO (new with AC) allows multiple devices to speak at one time (up to 4 clients) - affects capacity of antenna (30 device to now 120 devices)
• Beam forming (new with AC)

Notes:

• Bottom-left: Speed increases significant in shorter distances 20’ to 30’ (more distance, more noise)
• Wave 2: Double the lanes (MU-MIMO)
• Wave 1: WAPs max out at 3x3

otes:

• If 4 iPhone 6 connecting to 4x4 WAP, all four phones can speak at same time (1x1)
• If 4 iPhone 6s to 4x4 WAP, only two phones can speak at same time (2x2)

tes:

• All models are Wave 1, high-power
• Cannot go above 28dBm - signal begins to degrade

Fast Roaming

Notes:

• 90% of devices by 2019 will be dual-band
• Focus on 5 GHz
• Most Apple devices support fast roaming (iPhone 4s and newer)
• Samsung usually ahead of Apple (Galaxy S4 +)
• iPad Gen 1, older HP printers - not supported

IMPORTANT: If fast roaming not supported, client will NOT be able to connect

Guide to Success

Notes:

• Average of 5.7 connected devices in U.S> households
• 1 in 3 Americans using a tablet
• 69% of millennial say a wifi outage is more destructive that TV outage

Notes:

• Run temporary wires to test WAPs
