Frequently asked questions
1,000 Mbps. Networking has settled on decimal prefixes, so unlike storage this conversion has only one answer — a 1 Gbps link is 1,000 Mbps, not 1,024.
125 MB per second in theory, since there are 8 bits in a byte. In practice expect around 100-110 MB/s after protocol overhead. A 50 GB game download takes roughly 7 minutes at the theoretical rate and 8 to 9 in reality.
For most households the connection stops being the limiting factor somewhere above 100-200 Mbps. 4K streaming needs about 25 Mbps per stream and video calls 3-5 Mbps each, so ordinary use rarely saturates a gigabit line. Large downloads genuinely benefit. Gaming is far more sensitive to latency than bandwidth, and a gigabit connection does not improve ping. Wi-Fi coverage, the router and whether devices have gigabit ports usually bite first.
A thousand, by convention
A gigabit per second is 1,000 megabits per second in networking.
Mbps = Gbps × 1,000
Unlike storage, networking has essentially settled on decimal prefixes, so this conversion has one answer rather than two. A 1 Gbps link is 1,000 Mbps, not 1,024 — the binary convention that muddles storage capacities does not apply to transmission rates.
Where gigabit speeds appear
Home broadband. Gigabit fibre is now available across major Indian cities, and plans at 300 Mbps to 1 Gbps are mainstream rather than exotic.
Ethernet. Gigabit Ethernet (1000BASE-T) has been the standard port on computers and switches for years. Note that a device with a 100 Mbps port caps everything behind it at a tenth of a gigabit connection — a genuinely common bottleneck when an old switch or a cheap router sits in the path.
Wi-Fi standards, where the headline figures are theoretical maxima under ideal conditions:
- Wi-Fi 5 (802.11ac) — up to about 3.5 Gbps theoretical
- Wi-Fi 6 (802.11ax) — up to about 9.6 Gbps theoretical
- Wi-Fi 7 (802.11be) — higher still
Real-world throughput is typically a fraction of these — often a third or less — because they assume maximum channel width, maximum spatial streams, no interference and close proximity. A Wi-Fi 6 network delivering 400–600 Mbps in practice is performing well.
Data centre and backbone links, which run at 10, 40, 100 and 400 Gbps.
Converting to actual transfer rate
Divide by eight for megabytes per second:
- 1 Gbps = 1,000 Mbps = 125 MB/s
- 500 Mbps = 62.5 MB/s
- 10 Gbps = 1,250 MB/s
At 1 Gbps, a 50 GB game download takes about 7 minutes in theory, and more like 8–9 in practice once protocol overhead is counted.
Whether a gigabit connection is worth it
For most households, the honest answer is that the connection is rarely the limiting factor above about 100–200 Mbps.
Streaming — 4K needs roughly 25 Mbps per stream. Four simultaneous 4K streams need 100 Mbps.
Video calls — around 3–5 Mbps each.
Large downloads genuinely benefit, and this is the main case.
Gaming is much more sensitive to latency and jitter than to bandwidth. A gigabit connection does not improve ping.
The practical constraints that usually bite first are Wi-Fi coverage, the router's capability, and whether the devices have gigabit ports at all. Upgrading the plan without addressing those changes nothing measurable.
To verify what you are actually getting, test over Ethernet rather than Wi-Fi, and at a time outside local peak hours.
