- Owners, office managers and IT managers being asked to approve a connectivity upgrade.
A faster fibre package does not automatically create a faster office. The user experience sits across a chain: the internet service, the fibre termination, the router or firewall, the switches and cabling, the Wi-Fi access points, the employee's device and the cloud application at the far end. A bottleneck at any one of those points can make a 200 Mbps or 500 Mbps line feel slow.
What the report covers
- Why the line speed is not the office experience
- Bandwidth is only one number: latency, jitter and packet loss
- Where performance actually disappears
- How to diagnose before you upgrade
- A worked example: 200 Mbps, and still a slow office
- When more bandwidth really is the answer
- Questions to ask before approving a connectivity quote
- The Office Connectivity Bottleneck Test
Key points
- Start with a controlled wired baseline, then compare it with Wi-Fi in the places where people actually work.
- Repeat the tests during the period when the problem is reported, not when the office is quiet.
- Record latency, jitter and packet loss as well as download and upload speed. A line can test fast and still carry calls badly.
- Separate a line-capacity problem from a local network, Wi-Fi, endpoint or application problem before anyone quotes.
- The objective is simple: spend money on the part of the network that is actually limiting the business.
