NexusSec.NexusSec designs and deploys Aruba wireless and switching for businesses across Navi Mumbai, Mumbai and India — including RF site surveys, controller or Instant AP architecture, secure SSID design with proper segmentation, and access switching. Good enterprise Wi-Fi is a design exercise, not a matter of mounting more access points.
Why Wi-Fi deployments underperform
Most poor wireless we are asked to fix suffers from the same causes: access points positioned for cabling convenience rather than coverage, too many APs on overlapping channels causing interference, no site survey, and every SSID dropped onto the same flat network.
Adding more access points to a badly designed network usually makes performance worse, not better — co-channel interference is a common and counter-intuitive outcome.
Our deployment approach
- Requirements — device counts, applications, density, coverage areas and roaming needs
- Site survey — predictive design followed by on-site validation, accounting for real building materials
- Architecture — controller-based or Instant AP, depending on scale and management preference
- SSID and security design — corporate, guest and IoT separated onto distinct segments
- Authentication — 802.1X with proper certificate validation for corporate access, captive portal for guest
- RF configuration — channel planning, power levels, band steering, minimum data rates
- Switching — PoE capacity, VLAN configuration and uplink resilience
- Validation — post-deployment survey confirming coverage and throughput meet requirements
The single most important wireless security decision is what the network connects to. Corporate Wi-Fi should terminate in its own segment with firewall policy to internal resources; guest Wi-Fi should reach the internet and nothing else, with client isolation enabled. We verify this by testing — see wireless penetration testing.
Wireless security we implement
- Separate SSIDs and segments for corporate, guest and IoT devices
- 802.1X authentication with certificate validation, rather than a shared key everyone knows
- Client isolation on guest networks
- Rogue AP detection where the platform supports it
- Decommissioning legacy SSIDs, which are frequently the weakest entry point
Aruba switching
We deploy Aruba access and aggregation switching alongside wireless — PoE budgeting for AP and camera loads, VLAN configuration matched to the segmentation design, link aggregation for uplink resilience, and management-plane hardening.
