ClientLink(BeamForming)

Beam Forming is effective for downstream traffic (MRC for

upstream)

Measureable advantages:

Increased SNR at cell edges

Increased downstream data rates at cell edges

Increased downstream throughput at cell edges

ClientLink benefits the whole cell with an overall quality

coverage increased

Beam Forming is performed in hardware and use both

UDP and TCP traffic (no Bidirectional Traffic required)

Can beam form to up to 30 clients per AP

Applicable to legacy rates of 6, 9, 12, 18 (added for

outdoors) and 24, 36, 48, 54 Mbps

How Does Clientlink Work ?

How Does Clientlink Work ? Implicit Transmit Beamforming

Proprietary, works with 11a/g clients

No explicit feedback from clients

Implicit feedback through received packets

Relies on reciprocity of upstream/downstreamchannels

Same frequency on upstream/downstream

Beamforming weights derived from MRC weights

Store MRC weights (phase, amplitude) for eachsub-carrier

Apply same weights to antennas on transmit side

For adding capacity we rhave more than one RAPwith the same BGN, but channels

Design and PlanningHigh Availability Anti-stranded Features


77/91


Stranded: a MAP that is not able to associate and find a path to WLC

DEFAULT BGN (Bridge Group Name): Mesh APs with incorrect BGN, can st

network using BGN named DEFAULT. With DEFAULT BGN: MAP associates clients, and forms mesh relationships

After 15 minutes APs will go to SCAN state rather than rebooting

Do not confuse an unassigned BGN (null value) with DEFAULT, which is a mode that t

uses to connect when it cannot find its own BGN

DHCP fall back: this features allow a MAP configured with a wrong static IP a

back to DHCP and find a WLC. If even this fails, AP then attempts to discoveLayer 2 mode

FULL SECTOR DFS: DFS functionality allows a MAP that detects a radar sig

that up to the RAP, which then acts as if it has experienced radar and moves
