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:
