The modern dilemma of "my wi-fi doesn’t work!"

HOW many times have you been asked in the last couple of days:"Does anyone know the wi-fi code?"

Wi-fi and connectivity have become critical to our daily routine and operation.

Whether you’re on the go trying to connect to the airport lounge wi-fi, or catching up with e-mails over lunchtime at your favourite corner café, we have all asked the same question time and again.

But what about when you are sitting in your office and the internet stops working?

Nowadays when we encounter an internet glitch, we are very often instructed to "switch it off and back on again".

Every time I hear that someone has been prompted to do so, the effect that this has on me is the same as Quint making his legendary entrance in Jaws, when he drags his nails down the blackboard.

I am eternally grateful that those so very clever engineers spent all that time building a cute little box to house an on-off switch!!!

How else would we all solve the dilemma of hopping back online, than by pressing this magical button?

Client Steering, Band Steering, Beam forming, Smart Antenna, Auto-Healing, signal attenuation (loss) and Dual Band are just a few of the extra terms that the on-off captains will have to master.

What contributed towards your signal loss?

  1. Cubicle wall (fabric)
  2. Concrete wall

The answer: they are both the same, 18– 30 decibels.

Yes, the signal attenuation will vary according to the material, thickness and construction of any barrier, as well as the band being used (2.4GHz or 5GHz).

To provide the highest possible speed wireless connectivity for the widest range of devices, both new and old, wi-fi routers and access points often transmit and receive radio signals on two separate frequency bands.

This capability, which can now be found in most advanced Wi-Fi equipment, is known as dual-band wi-fi.

The frequencies of these bands are 2.4 and 5 GHz respectively.

I am not going to bore you with any technical details, but if you want our advice, and it is free, just ask one of our 2 Circles experts.

Wi-fi requirements for you or your business are going to become more and more important, so invest the time to find the best solution and try to future-proof it.

And just when you are all getting used to the technology, they change it up again.

Apple looks set to include a li-fi capability in future versions of the iPhone.

‘’Li-fi’’ I hear you all ask?

Li-fi uses modulated visible light from LEDs to transmit data to enabled devices.

It’s invisible to the human eye and it can access high-speed data using lighting.

Well, at least when it doesn't work, the new staple question that you’ll be asked in order to help solve your connectivity dilemma is going to be: "Can you see the light? Yes? Then it's on!."

Problem solved.
