Cisco Wireless wireless engineering
NetRobin works in Cisco enterprise wireless environments built on Catalyst 9800 controllers (and legacy AireOS deployments) with Catalyst and Aironet access points. Our role is engineering, not resale: we measure the RF environment, review how the controller is actually configured against the requirements of the environment, and recommend changes you can validate.
What the architecture looks like
- Catalyst 9800 controllers (appliance, embedded, and cloud forms) and legacy AireOS WLCs
- RF profiles, RF tags, policy tags, and site tags as the practical unit of configuration
- RRM: DCA, TPC, DBS/dynamic channel width, coverage hole detection, and Flexible Radio Assignment
- Client behavior features: 802.11k/v/r, band select, client steering, and Optimized Roaming
- Local mode versus FlexConnect forwarding and its impact on roaming and troubleshooting
Where NetRobin typically helps
- Controller and RF configuration review against measured RF conditions rather than defaults
- Roaming investigations where 802.11r/k/v behavior and client support do not match expectations
- Channel plan, channel width, and transmit power decisions in dense or multi-floor environments
- Capacity and airtime problems visible as high channel utilization or low PHY/MCS rates
- Post-change validation surveys so a configuration change is proven, not assumed
What we review and measure
- Controller configuration export, RF profile settings, and per-AP overrides
- Radio statistics: channel utilization, noise floor, interference, retries, and client counts
- Client-side measurements: RSSI, SNR, data rates, retries, and roaming events
- Over-the-air packet captures on the affected channels
- Spectrum captures where non-Wi-Fi energy is suspected
Common questions
Do you configure Cisco wireless controllers directly?
We review configuration and provide specific, justified recommendations. Where a customer wants us to implement changes, that is agreed in scope and performed in a controlled change window with validation afterwards.
Is RRM enough to keep a Cisco WLAN healthy?
RRM manages channel and power within the constraints it is given. It cannot fix AP placement, antenna selection, non-Wi-Fi interference, or an RF profile whose data-rate and channel-width settings do not match the environment. Those require measurement and design decisions.
