A question I get asked surprisingly often — both at work and at family dinners — is "how much internet speed do I actually need?" The honest answer is: it depends entirely on how many devices are in your home, what they're doing simultaneously, and whether your connection is stable enough to handle the peaks.
Counting Your Devices (You Probably Have More Than You Think)
Grab your phone and check your router's admin panel for connected devices. Most households in Bangalore are surprised to find 15–25 devices on their network: smartphones (everyone in the family), laptops, smart TVs, streaming sticks, gaming consoles, a smart speaker or two, security cameras, a smart doorbell, air purifiers with Wi-Fi modules, and sometimes even smart appliances. Each of these devices generates some level of background traffic — software updates, telemetry, cloud syncing — even when you're not actively using them.
A Simple Formula
Rather than guessing, here's a simple way to estimate your required bandwidth:
Count the number of simultaneous active streams (people watching different things at the same time) and multiply by 25 Mbps for 4K or 8 Mbps for HD. Add 10 Mbps per work laptop that's doing video conferencing. Add 10 Mbps as a general buffer for background IoT traffic. That sum is your practical minimum, and I'd recommend adding a 30% headroom margin on top of that for unexpected peaks.
For a family of four with two kids streaming 4K on separate devices, two work laptops, and a smart home with 10+ IoT devices, that math typically lands around 100–120 Mbps. A 150 Mbps plan gives you comfortable headroom.
Stability Matters as Much as Speed for Smart Homes
Smart home devices are notoriously bad at handling connection interruptions. A smart lock that loses its Wi-Fi connection during a firmware update can become a security issue. Security cameras that drop off the network don't warn you — they just silently stop recording. Voice assistants disconnect mid-command and give nonsensical responses. These aren't bugs in the devices; they're symptoms of a connection that dips below a minimum threshold, even momentarily.
We design our residential network with a "floor speed" guarantee — the minimum sustained speed will not drop below a certain level even during peak hours. For smart homes especially, this consistency is more valuable than the headline maximum speed.
