Frequently Asked Questions
Bandwidth is the maximum data transfer rate your connection supports (like a pipe diameter). Internet speed is the actual throughput at a given moment (how fast the water flows). Higher bandwidth doesn't always mean better speed if servers or routing are bottlenecked.
50 users × 5 Mbps (1080p) = 250 Mbps minimum. Add 20-30% headroom for other traffic = 300-325 Mbps. For 4K streaming at 25 Mbps each, you need 1,250 Mbps (1.25 Gbps) for 50 users.
Web hosting bandwidth = monthly visitors × average pages per visit × average page size. A site with 100K visitors/month, 3 pages/visit, and 2 MB average page size uses 600 GB/month (100,000 × 3 × 2 MB).
Traffic isn't uniform — most sites see 3-5× average traffic during peak hours. We apply a 3× multiplier to average bandwidth to estimate peak requirement for provisioning purposes.
Yes — video conferencing requires both upload and download bandwidth. Most ISP plans are asymmetric (higher download than upload). For a team of 20 on simultaneous video calls, ensure your upload speed is at least 20 × 1.5 Mbps = 30 Mbps.
