Li-Fi tested in US subway terrorist attack scenario

The attack scenario plays out at the Disaster Preparedness and Tactical Training Centre in Georgia.

The durability of Li-Fi, the system that delivers an internet service via the lights, has been tested during a terrorist attack drill in the United States.

pureLiFi, the company behind the technology, teamed up with Verizon, Nokia and Aegex Technologies to host the attack scenario at the Disaster Preparedness and Tactical Training Centre in Georgia.

The aim of the test was to demonstrate that Li-Fi communications could be sustained during a terrorist outrage, and could remain resilient under pressure in order to provide critical communications.  

The event, which was code named Operation Convergent Response (OCR), tested Li-Fi’s ability to maintain a real-time, bi-directional communications network that would be able to enable a communications and command centre to take charge of a developing situation.

The test also monitored the ability of Li-Fi to maintain communication between emergency services and central command.

‘This latest test proves that Li-Fi can provide reliable wireless communications in unpredictable conditions such as disaster circumstances.'

‘pureLiFi demonstrated that LiFi solutions could perform under real life operations and enable critical communications during response missions in chaotic and disastrous environments,’ Jeffery Schweitzer, chief innovation architect at Verizon commented.

The event featured a number of technologies, including internet of things (IOT) based products, that are able to improve communications during rescue operations and save lives.

Li-Fi uses light rather than radio frequencies, such as Wi-Fi, to provide wireless connectivity in areas that Wi-Fi cannot reach, such as power plants, petrochemical facilities, and hospitals.

Just last month Lux Review reported that it was hoped that Li-Fi would be able to provide wireless connectivity after the French government  moved to outlaw Wi-Fi in nurseries, schools and childcare centres that cater for children under six.

‘This latest test proves that Li-Fi can provide reliable wireless communications in unpredictable conditions such as disaster circumstances,’ commented Alistair Banham, pureLiFi CEO.

Li-Fi is currently in the early stages of development. However once completed, the installation of the technology on the Paris Metro is set to be its biggest success story to date. 

The Paris project is intricate and large in scale, requiring 10,000 light points to be fitted with Li-Fi technology. 

It is hoped, ultimately, that mini-Li-Fi receptors will be placed in smartphones allowing people to use their mobile phones via a wireless internet connection provided by the lighting.

Although this is still someway off, Li-Fi can currently be intercepted using a plug-in dongle that can be placed in a laptop. 

  • Li-Fi will be one of the main subjects of the LuxLive 2017 exhibition and conference on Wednesday 15  November and  Thursday 16 November 2017. Entry is free – pre-register to stay in the loop HERE.

What is the power consumption of the LiFi device in the fixture and the mobile device? All transmissions of data require power.....

I can see that possibly it can reduce children's ability to connect while in classrooms, but for emergency responders to use it makes little sense, because it requires connections to the lights doing the transmitting, and if those lights are damaged then they would not be functional. RF can be provided in tunnels using technology that has been fully mature for many years. Also, RF will pass through even thick smoke and dust clouds, unlike light. All of these limitations also apply to upstream communications as well. Li-Fi is still only a solution desperately seeking a problem.

Will the Li-Fi signal penetrate smoke?

I am in full agreement that children under the age of 10 (never mind six) should not be addicted to cellphone use via wifi. Children need to run, play, ride bicycles, swim etc. The WIFI via LEDs is an alternate method of providing security information. I am for that
