We see it all the time: a business buys 20 high-end access points, mounts them in a grid pattern on the ceiling, and then complains about poor wireless performance. The problem isn't the hardware, it's the design methodology.
The Problem with "Just Add More APs"
More access points don't automatically mean better coverage. In fact, too many APs can cause co-channel interference that degrades performance for everyone. Enterprise wireless design is as much about where NOT to place APs as where to place them.
Predictive Surveys: Design Before You Deploy
A predictive survey uses floor plans and building materials data to model RF propagation. This allows us to: - Determine optimal AP placement before drilling a single hole - Identify potential problem areas (concrete walls, elevator shafts, metal structures) - Calculate the right number of APs for your coverage and capacity requirements - Select the right antenna types for different environments
Spectrum Analysis: Understanding Your RF Environment
Before deploying any wireless network, you need to understand what's already in the air: - Neighboring WiFi networks that could cause interference - Non-WiFi interference sources (microwaves, Bluetooth devices, wireless cameras) - Regulatory considerations for outdoor deployments
The Right Hardware for the Right Environment
Different environments call for different solutions:
- Office spaces: Indoor APs from Cisco, Aruba, or Juniper Mist with omnidirectional antennas
- Warehouses: High-gain directional antennas to cover large open areas
- Outdoor spaces: Weatherproof APs from Cambium or Fortinet with proper mounting hardware
- High-density areas: APs with advanced beamforming and MU-MIMO capabilities
Post-Deployment Validation
After installation, we perform active site surveys to validate that the design meets the performance requirements. We test for: - Signal strength and signal-to-noise ratio in all coverage areas - Roaming behavior between APs - Throughput testing at various locations - Application-specific testing (video conferencing, VoIP, etc.)
Getting wireless right the first time saves money, reduces user frustration, and ensures your network can support the applications your business depends on.
