trudeau welcome to bbc news, broadcasting to viewers in north america and around the globe. there are big trash skimmers that my name's mike embley. are very expensive to buy, our top stories: to operate, they use fossil fuels, huawei isn't backing down. they don't reach into the chinese technology giant hard—to—reach places. it's not the only waste eater is expected to announce that's cleaning up waterways. it's suing the us government. over in the us, the baltimore—based mr trash wheel sucks in and processes republican senator martha mcsally heaps of rubbish. so far, it's cleared well over admits she was raped by a senior 500 metric tons of the stuff. officer while serving and in chicago, the inventively named trash robot is another remote—controlled robot in the military. tackling pollution. designed by dutch partner ranmarine, i blame myself. i was ashamed and the wasteshark is just confused. i thought he was strong. one of the solutions being used by ecocoast but felt powerless. behind bars — the us singer r kelly is back in custody after a court hearing over unpaid child support. and we talk to the celebrated to improve dubai's waters. photographer who's been documenting british society for nearly half a century. the company has also deployed bubble curtains to prevent silt and other contaminants left over from construction reaching the ocean, a real problem due to dubai's ever evolving landscape. the bubbles behave like a barrier,

restricting the movement of floating and subsurface pollution. for us what's very important is what solutions will prevail in the future. you'll have pods of wastesharks that are cleaning the waterways that are autonomous, that are self charging, self emptying, and they're constantly feeding back data to the end users. gathering data on water quality and areas of high contamination could help marina owners and local governments record and know more about the state of their shores. dubai municipality has just adopted two that will begin patrolling public waterways in a couple of weeks. a noble effort, but with an estimated 800 million metric tons of plastic ending up in our oceans every year it's tough to see how these tiny trawlers will make much of a difference. but at least for now, bottle by bottle, it's helping us protect our planet. back in barcelona, i was once again surrounded by 56 signs, the same as previous years.

but this time, it really felt like the tech was a lot more ready to make its mark. a few sg—enabled phones are hitting the shops this year, but 56 is not really about a faster connection with our mobiles. it's more about connecting the things that we've never connected before. stands were full of ideas about what that could mean for the future. a robot that can instantly mimic its driver's moves. imagine this happening when they are thousands of miles apart, and this is the kind of collaboration that 56 promises to unlock.

wearing ar goggles can let you interact with the same 3—d environments, but without the kind of uninterrupted connection 56 should provide, the experience will always fall short. so frustrating. this collaborative game is set up on wi—fi at the moment, the reason being to demonstrate how the haptic feedback is a little bit delayed. whereas once it's on 56, well, it should all be happening at the right speed, exactly as i do things — although i don't think it's going to improve my skills. and it can truly unleash the power of ar. we already have ai capabilities in our devices. image recognition, for example, helps to enhance our photos. i played a simple game which shows the speed that our devices can recognise an object in an image. i'm really trying my best here, but no matter how quick i feel like i am, the computer is a lot quicker. the only thing is, at least i get it right every time. if you pull it all together with 56, suddenly you have a very,

very highly performing device that's connected to the cloud with a very low latency. so you can actually have almost immediate responses based on where you are, your context, and that changes the way your device interacts and what you can do with it. for example, if you were actually going on a run and you actually — now, your phone is capable of giving notjust canned exercises, but training as you go along, that is tuned to how your body is responding to it. 56 might make the relationships with our phones a bit more personal. on a grander scale, the entire travel infrastructure around us could be transformed. this is part of millbrook proving ground, the place where cars and their components are put through their paces. but right now, it's serving

as a testbed for 56, and what that could mean for autonomous and connected vehicles. while ag radios still need to be used at the moment, the rest of the trial sees movements and interactions tracked on a 56 network. it replicates what could in the future keep traffic safe and well managed. the number of cars today which have it in them, that will evolve into algorithms that help those sensors connect. i think the really key thing is how are you going to use the data to be able to help make the end user's life easier? and that is what is being looked at here. can we get the vehicle to be connected, can we make sure that we're transferring the data? can we do that in a safe and secure environment, so that the data itself is secure? then, can we make sure that the cars themselves are secure from each other, but also are they secure from unexpected events?

the much—talked—about low—latency aspect of 56 means no delay, and that is of course vital when we're talking about moving traffic. this mclaren is travelling at 160 mph. but, in a 200 metre radius, the cars would be able to wirelessly track each other too. even here it feels like there were a lot of vehicles moving very fast, but of course, in the grander scheme of things, these are just a few. we're looking at all of the vehicles on all roads being tracked in this way, and that is a big job. when we talk about millions of devices to be connected to the network per kilometre square, then we talk about cars, homes, streets, hospitals, factories. what we are exploiting here,

the technology, it's parallel computing and parallel signal processing. so we have a large number of processing units in parallel, to do the number—crunching in the minimum amount of time. in terms of ai, when we talk about the automation part of the sg, when robots are connected or devices are connected, ai plays a very important role in terms of understanding what the device wants to do, or what the device should be doing, and forecasting and predicting in future. but, if all of these vehicles and all cars on the road are relying on that mobile phone network, what happens if it goes down? well, i think what we do as a mobile operator is we continue to look at our network. we did suffer an outage with one of our partners, and that was quite public. we're looking constantly at how we can make sure our network is more resilient in the future, and i think one of the things that will come out of here is how do we make sure that the vehicles themselves are resilient, from a network point of view? before we reach a state of fully connected autonomy, though, 56 could have its work cut out on road and rail,

providing more accurate live tracking and information. we know that, from some of the work we've done on our smart cities report, that from a train transportation point of view, rail sensors working on preventative maintenance can take out £450 million of lost productivity, and that equates to about 2.6 hours per commuter per year of time saved. and then, from a road point of view, having a really good, connected 5g road management system could help take out 10% of time waiting in traffic. and that, you know, for 5.6 million commuters on the road, that would be a real saving. so many phones, so many promises. but do they all live up to what they're offering? 0mar mehtab has been putting one to the test. this is the agm a9 smartphone.

it has features you would expect of many top—brand devices — quick—charging, fingerprint id, big screen. but it's also quite solid. now, this phone isn't for your average user. it is designed to survive the toughest of conditions, so tough, in fact, that the company say it is unbreakable. agm advertise their phones as being able to survive quite some punishment, such as being able to be kicked like a football. so we asked the company if it could survive a hammer. they said yes. ah, right. that didn't take much. right. that's broken. that is smashed, but to be fair, maybe it wasn't designed to actually take a hammer to it. it's gone completely. 0k, ok, that's just the screen. it's easily replaceable, no problem at all. and the back of the phone was proving a lot tougher, so i got some help.

be careful. oh, yeah — and don't try this at home. 0k, you've done it. you've cracked plastic. you've cracked the plastic. look at that. oh, it's lifted completely. so despite saying that we could use a hammer, agm came back to us and said that the military—certified phone can endure a lot, being waterproof, shockproof, dustproof, but a hammer will compromise it. look at that. so he broke the camera lens. yes, a long way off from unbreakable, like the company said. 0mar there, having a smashing time. but you don't need to go that far to disconnect. so how about this — a phone which will keep you connected when you need to be, but doesn't provide all of the distractions of a smartphone? now, don't think that this is just

the basic device that can't do much. the idea is actually that it's a premium product. it has up to 270 hours‘ battery life, blackberry security, and a rather bold pricetag of £295. the company anticipates it will be bought by those who already have a smartphone, but fancy the option of some calmer moments. well, that's it for the mwc special. you may not be able to do it on here, but if you want to keep track of the team throughout the week, you can find us on facebook and twitter. thanks for watching.

hello. a vigorous jet stream pushing areas of low pressure right across the uk is the weather pattern we're in. and we are staying in all the way through the weekend into next week as well. here is a recent satellite picture. this is swirl of cloud is an area of low pressure, edging its way eastwards. but as it does that it is dragging in behind it some colder air as well. and what will be a strong and gusty wind as we go on through thursday. we've still got some wet weather to clear away as well. most noticeable, for thursday's weather, will be that strong wind. and for many of us how much colder it feels compared with wednesday. this is how we are starting the day. nothing particularly cold first thing, there is too much wind and cloud for the temperatures to have dropped too far overnight, and this is where we are starting the day with wet weather through northern ireland, scotland, some hill snow. it is pushing slowly southwards during the day, but not much reaching the far south

of wales or southern england until quite late on. and, again, that's moving south with strong, gusty winds. let us take a wind speeds and temperatures during the afternoon at three o'clock and where the wet weather will be. very gusty winds. much of scotland will be brightening up. a few showers following on. wintry on the hills. brightening up for northern ireland through the afternoon. a lot of cloud through northern england, into the midlands, east anglia, with the outbreaks of rain pushing south. bright spells in south wales into southern england, maybe the odd passing show during the day. also very gusty winds. in the evening we will pick up showers in the far south and south—east. that is clearing away on thursday night and into friday morning. as that happens and the winds eventually ease, temperatures will drop away. plenty of widespread frost as friday begins. temperatures will be lower, away from towns and city centres. highland scotland could be —5 or —6 as friday begins. the odd mist and fog match. a lot of sunshine to start the day, not going to last. quite quickly cloud increasing from the west.

quite a cold feeling day. you can see more hill snow to come in scotland out of that. that's friday covered. i want to show you the big picture for the weekend. still with the jet stream driving weather disturbances across us. it will be wet at times over the weekend. looks to be pretty windy throughout the weekend as well. but still something to play for in the detail aboutjust how wet and when it will be wet. so keep up—to—date with the latest forecast, but these are the main thing is for the weekend. just bear in mind it's not going to be wet all the time, there will be some sunshine at times, too.
