Bring your network with you

At last week’s Critical Communications World, Motorola unveiled the LXN 500 LTE Ultra Portable Network Infrastructure. It allows rescue personal to set up dedicated LTE networks for communication in an emergency, writes SEAN BACHER.

In the event of an emergency, communications are absolutely critical, but the availability of public phone networks are limited due to weather conditions or congestion.

Motorola realised that this caused a problem when trying to get rescue personnel to those in need and so developed its LXN 500 LTE Ultra Portable Network Infrastructure. The product is the smallest and lightest full powered broadband network to date and allows the first person on the scene to set up an LTE network in a matter of minutes, allowing other rescue team members to communicate with each other.

“The LXN 500 weighs six kilograms and comes in a backpack with two batteries. It offers a range of 1km and allows up to 100 connections at the same time. However, in many situations the disaster area may span more than 1km which is why they can be connected to each other in a mesh formation,” says Tunde Williams, Head of Field and Solutions Marketing EMEA, Motorola Solutions.

The LXN 500 solution offers communication through two-way radios, and includes mapping, messaging, push-to-talk, video and imaging features onboard, thus eliminating the need for any additional hardware.

Data collected on the device can then be sent through to a central control room where an operator can deploy additional rescue personnel where needed. Once video is streamed into the control room, realtime analytics and augmented reality can be applied to it to help predict where future problem points may arise. Video images and other multimedia can also be made available for rescuers on the ground.

“Although the LXN 500 was designed for the seamless communications between on ground rescue teams and their respective control rooms, it has made its way into the police force and in places where there is little or no cellular signal such as oil rigs,” says Williams.

He gave a hostage scenario: “In the event of a hostage situation, it is important for the police to relay information in realtime to ensure no one is hurt. However the perpetrators often use their mobile phones to try and foil any rescue attempts. Should the police have the correct partnerships in place they are able to disable cellular towers in the vicinity, preventing any in or outgoing calls on a public network and allowing the police get their job done quickly and more effectively.”

By disabling any public networks in the area, police are also able to eliminate any cellular detonated bombs from going off but still stay in touch with each other he says.

The LXN 500 offers a wide range of mission critical cases and is sure to transform communications and improve safety for first responders and the people they are trying to protect.

The myths of microwaves

Published

on

We all know microwaves make cooking a breeze and it helps save those minutes, we rarely have enough of these days. However, some people do have those lingering doubts about whether microwaving food destroys nutrients or that it emits harmful radiation. However, the truth is a lot more comforting and positive.

“The microwave makes life so much easier,” says Tracy Gordon, Head of Product – Home Appliances at Samsung South Africa. “It’s human-centred technology at its most helpful. The Samsung Hotblast for example, has revolutionary functions, which are tailor-made to create fast, tasty and healthy meals in minutes.”

A recent article by Harvard Health Publishingclaims stated that “microwave ovens cook food using waves of energy that are remarkably selective, primarily affecting water and other molecules that are electrically asymmetrical. Microwaves cause these molecules to vibrate and quickly build up thermal (heat) energy.” The article debunks two common myths about microwaving food.

Myth 1: Microwaving kills nutrients

Whether in a microwave or a regular oven, some nutrients, including vitamin C, do break down when exposed to heat. However, the fact is, cooking with a microwave might be better when it comes to preserving nutrients because it takes a shorter time to cook. Additionally, as far as vegetables go, cooking them in water robs them of some of their nutritional value because the nutrients seep out into the cooking water,” states the report by Harvard Health Publishing. According to the World Health Organisation (WHO), food cooked in a microwave oven is as safe and has the same nutrient value, as food cooked in a conventional oven.

Myth 2: Microwaving food can give you cancer

The American Cancer Society (ACS) says that microwaves do not make food radioactive. Microwaves heat food but they do not change the chemical or molecular structure of it. In fact, there is absolutely no evidence that microwaves pose a health risk to people when used appropriately, the organisation added.

With those myths well busted, it’s comforting to know one can make full use of the convenient kitchen appliance. And when the time comes to use a microwave to heat up a tasty meal in no time, one can trust the Samsung Hotblast to do the job. The HotBlast has multiple air holes blowing out powerful hot air, which reduces cooking time. Samsung claims the Slim Fry technology ensures that food is perfectly crisp on the outside and delicious and juicy on the inside. Additionally, this versatile microwave has a wider grill, making it easier to brown food fast and evenly. The turntable is wider, measuring 345mm, making it possible to prepare bigger portions of food. And with its Eco Mode power, it significantly reduces energy consumption with its low standby power. Its intelligent features and stylish design makes it very useful and as we now know – a safe, healthy way to enjoy a meal.

New BMW 3-series ushers in autonomous future

The new BMW 3-series is not meant to be an autonomous car, but it is so close, ARTHUR GOLDSTUCK discovers.

It was not meant to be a test-drive of an autonomous vehicle. But the Driving Assist button on the steering wheel of the new BMW 330i was just too tempting. And there I found myself, on Sir Lowry’s Pass near Cape Town, “driving” with my arms folded while the vehicle negotiated curves on its own.

Every 10 seconds or so, yellow or red lights flashed to alert me to put my hands back on the wheel. The yellow lights meant the car wanted me to put my hands on the wheel, just to show that I was in control. The red lights meant that I had to take over control from the artificial intelligence built into the vehicle.

With co-driver Ernest Page, we negotiated a major highway, the bends of Sir Lowry’s pass, and the passes of Hell’s Heights (Hel se Hoogte) above the Cape Winelands.

As the above video of the experience reveals, it can be nerve-racking for someone who hasn’t experienced autonomous driving, or hasn’t been dreaming of testing it for many years. For this driver, it was exhilarating. Not because the car performed so magnificently, but because it tells us just how close true autonomous driving really is.

There was one nervous moment when the autonomous – or rather, Driving Assist – mode disengaged on Hell’s Heights, but fear not. A powerful sense of responsibility prevailed, and my hands hovered over the steering wheel as it took the curve. Assist disengaged, and the car began to veer towards the other side of the road. I quickly took over, and also sobered up from the giddiness of thinking I was already in the future.

In reality, Driving Assist is part of level 2 of driving autonomy, as defined by the Society of Automotive Engineers. A presentation on the evening of the test drive, by Edward Makwana, manager of group product communications at BMW Group in South Africa, summed up the five stages as the driver having Feet Off, Hands Off, Eyes Off, Mind off, and finally, only being a Passenger.

However, the extent to which the hands-off mode of Driving Assist mimics self-driving, and easily shows the way to eyes-off and mind-off, is astonishing.
