Here’s a step-by-step guide to calculating bandwidth needs for multi-department clinics:
The Basic Formula
N × T = BN
Where:
-
N = Number of users/devices
-
T = Traffic estimate (bandwidth per activity type)
-
BN = Total Bandwidth Needed
Step 1: Count Users and Devices per Department
List all users and internet-enabled devices across departments:
Total users = N (FCC recommends counting all employees + IoT devices)
Step 2: Assign Bandwidth Requirements per Activity
Modern clinics use multiple bandwidth-intensive applications. Here are the per-user requirements:
Key benchmark: FCC recommends 10 Mbps for <5 physicians, 25 Mbps for 5-25 physicians, 100 Mbps for hospitals, and 1000 Mbps for large systems.
Step 3: Calculate Total Bandwidth by Department
Use the formula N × T = BN for each department:
Example: 15-Physician Multi-Department Clinic
Reception (5 users × 1 Mbps browsing/EMR): 5 Mbps
Consultation (10 physicians × 4 Mbps for EMR + telemedicine): 40 Mbps
Lab (6 users × 15 Mbps for imaging): 90 Mbps
Pharmacy (3 users × 2 Mbps): 6 Mbps
Admin (4 users × 1 Mbps): 4 Mbps
Guest Wi-Fi (20 patients × 3 Mbps): 60 Mbps
CCTV (8 cameras × 3 Mbps): 24 Mbps
Subtotal: 5 + 40 + 90 + 6 + 4 + 60 + 24 = 229 Mbps
Step 4: Add Peak Usage Buffer (+20-30%)
Network protocols and traffic spikes require overhead:
Total with buffer = 229 Mbps × 1.25 = 286 Mbps
Step 5: Match to FCC Benchmarks
For your clinic size:
Your 15-physician example needs 286 Mbps, which exceeds the FCC minimum of 25 Mbps because you’re using telemedicine, imaging, and guest Wi-Fi.

Quick Checklist for Your Clinic
-
✅ Count all users + IoT devices (diagnostic tools, monitors, phones)
-
✅ Identify peak usage times (e.g., 9 AM-12 PM when all departments are active)
-
✅ Factor in telemedicine needs (2.5-3.5 Mbps per HD call)
-
✅ Include medical imaging transfers (10-50 Mbps per file)
-
✅ Add 20-30% buffer for network overhead
-
✅ Consider upload speed (telemedicine needs 3+ Mbps upload)
-
✅ Plan for future growth (add 10-20% headroom)
Pro Tip: Use a Business Bandwidth Calculator
Tools like Power Fibre’s Business Broadband Bandwidth Calculator let you input:
-
Team size
-
Video call frequency
-
Cloud usage
-
CCTV/EPOS systems
-
Guest Wi-Fi needs
This gives automated recommendations for FTTP speeds.
For most multi-department Nairobi clinics, Wavelink Networks’ Business Elite (100+ Mbps) or dedicated fiber (200-500 Mbps) plans provide reliable connectivity for EMR, telemedicine, and imaging.
