802.11 Challenges for Voice and Data


802.11 Challenges for Voice and Data

Four fundamental problems must be solved to achieve enterprise level performance for high density voice and data for WiFi networks:

1. Single cell contention

2. Contention across cells

3. Jitter and volatile bandwidth allocation

4. Slow hand-off

)• Multiple clients contend for the same shared medium

• While transmitting sender cannot listen for collisions

• As number of calls goes up, collisions increase

• Collisions cause clients to backoff

• Backoff slows down network

• Requires more than scheduling

No Traditional Site Surveys- EzRF™Meru Networks controls co-channel interference and runs on a single channel

• Channel planning required to avoid co-channel interference

• Co-channel interference from adjacent cells degrades performance

• Voice and Data on network require careful planning

• Multiple channel re-associations cause low QoS and poor handoffs

• Move/add/change WILL require re-planning for RF and co-channel interference

• Micro-cell design philosophy compounds the problem

Traditional designs use channels 1-6-11:

► No Channel planning required to avoid co-channel interference…just paint for coverage

► Co-channel interference controlled by system► Voice and Data on same network (no micro cell designs)► Zero Hand-off (less than 3ms) between cells► Move/add/changes WILL NOT require re-planning for RF and

co-channel interference…just fill gaps, system controls interference

► Allows for redundant APs without RF issues► Other channels available: i.e. B on 1 G on 11► Automatic load-balancing of clients between APs

Meru designs use single channel:
