Can five degrees decide whether your network survives rising temperatures?

Five degrees might not sound like much when you look at the weather forecast.

But for the networks our everyday lives depend on, it can mean the difference between equipment running reliably and being pushed past the limits it was built for.

That matters more every year as extreme heat becomes more common.

Heatwaves, wildfires, severe storms, and prolonged periods of high temperatures are putting IT infrastructure under pressure in places that were never designed for these conditions.

At the same time, the hardware inside our networks is becoming more powerful and densely packed, making it even harder to keep cool.

Traditionally, outdoor wireless equipment has been designed to operate at temperatures of up to 60°C, taking into account both the heat outside the equipment and the heat generated by the hardware itself.

But some vendors are now lowering that ceiling to around 55°C.

As temperatures rise and access points generate more heat of their own, that five-degree difference could be critical.

Our networks are getting hotter The pressure is building as wireless technology evolves.

Access points, for example, have gone from housing two radios to three or four, and each extra radio adds more heat that has to be dissipated.

As a result, vendors are having to think carefully about how they balance heat and power as they pack in more performance benefits.

Wi-Fi 8 could also raise the stakes even further.

Future wireless platforms are expected to incorporate more AI-assisted processing at the edge, increasing demand for compute resources, memory and power.

But that extra processing power and memory will also need more power and will generate more heat, creating another challenge for vendors trying to keep their equipment reliable in demanding environments.
