night. and will come south over the night. and they will become very wintry over higher ground. elsewhere, more cloud than last night. around about two to 4 degrees. a chilly start to the bank holiday monday. the line of cloud is coming and it will bring some showers as well. either side of that line you should state mostly dry. some sunny spells here and there particularly across parts of scotland, but not very warm. temperatures just 13 degrees. goodbye.

hello, this is bbc news. the headlines. the prime minister appeals to jeremy corbyn to resolve their differences and help her deliver brexit. but the shadow chancellor says a crucial factor, trust, has been broken. ina word, in a word, a single word, do you trust the prime minister? no, not after this weekend, when she's blown the confidentiality act. i think she isjeopardise negotiations for personal protection. police forces in england and wales are urged to rethink their policy of asking rape victims for access to messages and photographs on their phones. thailand's king makes a grand procession in front of large crowds in bangkok, in his first public appearance since his coronation on saturday. the illegal puppy trade exposed, the treasury recovers more than £5million in unpaid taxes, in an operation to tackle the black market trade.

now on the bbc news channel, it's time for click. this week, it's 56 whiz, with superfast connections, connected cows — and also the end of the world? whenever you're out and about, your mobile phone communicates with the rest of the world through these. calls, messages and data are sent from masts like this to hundreds of phones within a few kilometres and each of those phones send calls and data back again.

it's a lot of work for one mast to do and it kind of explains why if there are too many phones in any one area, things start to slow down. but it won't always be like this. our next mobile network will be the fifth generation, called sg. and it will be very different to what's come before. 16 was about the analogue phone, allowing us to make calls to one another. zg allowed us to do things like send sms text messages and do voice recording. 36 was about the promise of the smartphone, allowing us to access digital broadband services. and ag, which is what we've had since 2009, allowed us to do all those first three things but faster. 56 is like going from earth to mars. it's not a faster world, it's a different world. it's going to be a world that is connected, in which machines will be talking to each

other and talking to you. and to achieve that, we are going to have lots and lots of antennae everywhere. on lamp posts, buildings, you name it, it's going to have an antenna on it. and that's because there are billions and billions of new devices waiting to be connected that will communicate with each other, work with each other and make our lives easier in ways that we can't yet imagine. tv off, lights off. machine: tv off, light off. april was very dry. it will allow you to control your energy consumption in your smart home. it will allow your fridge to decide when to order groceries for you and have them delivered by a self—driving truck. it will allow your dishwasher to decide when it washes dishes, your laundry machine decide when it washes clothes. so right now, we have to instruct our machines but in the sg worlds, our machines might decide to communicate directly to us or with each other.

the machines will start communicating simply to regulate the flow of human activity. your car is going to be connecting and thinking, interacting and communicating with every other sensor that happens that's walking down the street as it passes a building, as it passes a somebody on a bicycle. information from a traffic light three blocks down that you can't even see yet. it's going to be completely seamless. 56 will enable all these devices to have superfast data connections but we also need them to be stable connections as one device hops rapidly between all of these antennae. how rapidly? well, maybe this rapidly. this is the millbrook 56 test bed. one of the things i'm testing here is how well 56 antennae can follow a moving target. there is an antenna and i'm the target. i am making a live video call to the computer trackside

which is actually really hard to do when you're moving at speed. at 140 miles an hour, each antenna can only send stuff that afternoon, labour‘s shadow chancellor has accused the prime to my special sg hotspot in the car for about four seconds and so here, minister of breaking the confidentiality and the trust between labour and government. she each one has to form a beam which targets the car exactly and then hands over the service seamlessly to the next antenna, has called on jeremy between labour and government. she has called onjeremy corbyn to put all without interrupting their differences aside. the exit the video stream. was delayed to the 31st of october. the kind of technology that blu wireless is testing here will eventually enable high—speed trains to stay connected the to the 56 network and provide superfast internet to their passengers. to coverjust this small area, they are using 11 antennae here so if you want to blanket the whole uk with 56, you are going to need a huge number of the things. i mean, this is a massive infrastructure rollout.

and the scale of all this is something being grappled with around the world. in the us, verizon has stepped up its trials in us cities, albeit only over small areas. speeds, when it works, are impressive, although the trials are said to have had some teething problems. cities in south korea and china could well get the first meaningful services but what about if you're not in a city? well, back in the uk, jane copestake has been looking at what 56 might mean for rural areas. in this idyllic patch of british countryside, the birds are cheerfully singing and the cows are peacefully grazing. but look closer and you will see there is something very different about these cows linking them to a unique experiment. this dairy farm in somerset is one of the first test spots for 56 in the uk. the cows are wearing sensors

and all this data is being sent to the cloud and then back to the farmer who can make decisions based on this data. almost every task on this farm can be automated. these cows are queueing up patiently to be robotically milked. this system allows the cow to choose how many times a day and at what time it wants to be milked. the robot picks up on how much milk is coming from each of the cows udders and can control the sensitivity of the milking as well. the cows here come and go as they please, with little human interaction in their movements. so one of these cows has just taken itself for a massage. the feeding system is also done by machine, and that's not all. there is even a robot that scrapes up excrement, putting it into these channels which can quietly operate around the cows so as not to disturb them. duncan forbes runs the farm. he's been working with cisco on this project which is part of the uk's sg rural first strategy.

the farm is chosen to demonstrate how 56 would help bring together the many different points of data across a herd of cows. low latency and the ability to cover large distances with 56 means that the cows can be monitored in real time, even if they're grazing in the field. what senors is she wearing? can we see any of them? on the collar, there is a little black square that says "fa milk silent herdsman" on it so that's one of the sensors and it's an activity monitor. like a wearable, like a watch. yes, but the sort of thing it does is tell you when the cow was eating, so there's an inclinometer, so when her heads down, it says ok, she's eating. she's got the green one, the transponder underneath her chin. and that's the one that controls the gates and so on inside the building. it's an electronic identity. the third one isjust inside her rear, the little white button on the top of the ears is holding the sensor.

so these cows have got more sensors than you would necessarily have on an ordinary cow because we are trying it out, we are testing them and we are checking out their connectivity. here, we're on a dairy farm and we're using the technology to help us with our animals but we're also going to have sensors around the fields telling us what the soil moisture is, what the temperature of the soil is, measuring the grass growth, using satellites or hyperspectral imaging to measure how much grass we've got but also saying, maybe we don't need to use quite so much fertiliser. 56 could revolutionise the farming industry, connecting notjust the uk farms but farms around the world so best practices can be compared and new techniques developed. imagine if you would be able to cross—correlate data, not only about how a cow is doing well, if it's sick within the farm but across multiple farms, across multiple areas. imagine the efficiency you could get if you were able to manage the robots based on the best possible efficient way of doing it instead ofjust within a farm.

one of the biggest challenges for farming worldwide is the expected increase in world population where we're going to need to produce 70% more food than we were producing in 2009 by 2050. that's a massive increase. we've got to produce that food without additional impact on the environment, preferably less. a byproduct of bringing the sg network outside of cities could be a revolution in connection speeds of the countryside. a recent national farmers' union survey showed only 17% of respondents reporting a reliable outdoor mobile single and only 16% saying they had access to superfast broadband. the farmers here hope to make a strong economic case for bringing connectivity to all parts of the country, no matter how remote. hello, welcome to the week in tech. a drone has, for the first time, delivered a human organ.

surgeons in maryland received a kidney transplant from about 3 miles away. and facebook ceo mark zuckerberg announced new measures to improve a users privacy as he laughed off his company's recent failures. the strongest reputation on privacy right now. updates include a friend feed free of adverts and an encrypted messenger service. meanwhile, the uk government is preparing to plan new laws that will mean that all internet—connected devices need to have cyber security features built in. it proposes all devices sold in the uk come with unique passwords, state how long they will receive security updates for and provide contact details to report vulnerabilities. we may have seen ai—generated faces before but how about entire—generated people? well, meet this lot. these photorealistic images byjapanese company datagrid come

complete with faces, hair and even outfits. and finally, if you haven't worked up an appetite for lab—grown meat, then how about a spot of lab—grown fish? singapore start—up shiok meats won't be scrimping on the shrimps after raising $4.6 million to keep working on their cell—based delights. but are you ready to dive in? to build the 56 network, you need a new type of telecoms gear. you need many more base stations and they need to be smarter. it is the chinese tech company huawei which makes the most advanced sg gear but this has been making western governments nervous, so i've come to find out — who are huawei? it may look like paris but this

is huawei's brand—new campus in shenzhen, china, a huge site where employees take a train between office buildings, each of which is modelled on a different european city. fewjournalists have visited this disney world—like project, very much the brainchild of ren zhengfei, the company's founder. he's compared to the likes of stevejobs, growing his company from a small workshop into a tech giant now employing 180,000 people. huge spending on research means huawei claim they are now around 18 months ahead of any other 56 manufacturer, and that includes not just getting faster and faster data speeds but dealing with the problems that come from higher performance. so this is the sg wireless base station. the 56 power is around 1,000 watts.

and how much bigger is that than a 4g base a station? a 4g base station is average power of 300 watts. so it's three times larger. so this uses three times as much power, so it gets hotter. yes, much hotter. it's a common problem in technology. as things get faster and they consume more power, they get hotter, and new cooling techniques need to be developed. this is liquid cooling cycling. is that liquid boiling in there? it's bubble. here, they are learning how different designs and materials can change the speed and direction that heated air flows away from the components. and here's an experiment to try and keep everything at a stable temperature, by either applying heat or cold on demand. that's gone cold. yep, that's hot.

huawei is currently enjoying huge success, with revenues last year in excess of $100 billion. but this is also a company facing some serious issues. the biggest is that the us is coming for huawei in a big way. we have met the enemy and it is huawei and it is china, make no doubt about that. right now, huawei, through access to unlimited capital from the chinese government, the communist government, all of this technology, guess what, it's built in for cyber spying, for cyber espionage because that's what the chinese do. the problem is, mr ren was once a member of china's people's liberation army and that's raised suspicions about his links to the chinese state and whether it and huawei make have each other‘s backs. america is adamant that huawei is a pawn of the chinese authorities. humans in 2017, china passed

the national intelligence law which says that if asked, all chinese companies and citizens must help the government to assist national intelligence efforts. china claims this is part of an effort to safeguard its security. but the fear is that if huawei supplies any country's 5g network, the chinese could exploit it. to help the government decide whether huawei should be in the uk's 5g network, the british security services have a special unit devoted to looking at the potential risks posed by huawei. it is overseen by doctor ian leavy, hisjob is to defend the uk against digital attacks. he rarely gives interviews. does huawei pose more of a security risk than the other companies that supply the network infrastructure? i think what we're talking about is, assume that chines state wants

to attack the uk telecoms networks. ourjob is to try and make them work just as hard regardless of whether we use huawei kit or not. many people think the chinese state would love to eavesdrop on other countries. if we let huawei into 5g, is that a real danger? it's no more likely to have spying or communications in 5g that it is in ag, and anything that is critical, whether it's government, business, even personal communications should be encrypted. so, you know, all of the communications with your bank from your smartphone, they are all encrypted because you don't want to trust the wi—fi and the telecoms networks. so if someone is listening on the line, they willjust get garbled gobbledegook? yep. and it's the same for critical stuff in business, in government, in control systems. so, according to gchq, the threat of spying that we've heard so much about recently is overblown. but there is another threat that they take very seriously. in a future where our entire

infrastructure, our economy and our lives are run by computers talking to each other over a 5g network, what would happen if someone shut that network down? if you think about it, the future of warfare is not necessarily going to be using traditional armies in the way that we think of, like with the second world war. the future of welfare is most likely going to be cyber, so without firing a shot, you could take a country out. it's feared that the chinese state could order huawei to build secret backdoors in a 5g network. these would leave the country vulnerable to a nationwide cyber attack. and that could be catastrophic. what we are about to show you is what experts have told us could happen if the uk's 5g network was attacked in the not—too—distant future. i don't know, the station's been

shut for nearly an hour. there is no information, there are no buses. it's a nightmare! inaudible. tell me where the trouble is? m11 has completely stopped, the m1 and ma are both backing up. no accident? nothing. can i get through to traffic please? hey, can you hear me? the traffic‘s gone crazy! michelle? are you still there? i've got police and ambulances stuck everywhere, the national grid are gonna shut things down, it's a terrible mess! within the last hour, bbc news has received hundreds of reports of widespread disruptions across the uk, with numerous services

being affected. i don't know, it's just flashing, i don't know what's going on. it's just not driving. many roads are blocked after a variety of self driving systems deactivated. the government is advising only to travel if absolutely necessary. many shops have had to close due to being unable to take payments after the pay network went down. the ultimate cause of the disruption has yet to be confirmed. what's going on with the feed? can we get them back up again? can we get the feeds back up? they are offline! we are also hearing that the smart grid has been overloaded and power supplies are being hit nationwide. guys, listen up, national grid are going to shut down midlands and the north, 0k? that's going straight away. lights on. lights on! sirens blaring.

tv on? tv on. this is being considered a national emergency... as soon as we recieve any information, we will, of course, share it... static. this is a worst—case scenario but it is possible. so, would huawei deliberately expose their foreign customers to beijing—backed attack? translation: the chinese government explicitly requires all chinese companies to strictly follow local laws in every country they operate in. the chinese government has never, and will never, ask any chinese enterprise to install backdoors.

i can say with certainty that huawei has never installed backdoors in its equipment in the past, and neither will we do such a thing in the future. but, the latest gchq backed report published in march found that there are security holes in huawei's equipment. 00:23:13,992 --> 2147483051:48:21,711 what was the overall result 2147483051:48:21,711 --> 4294966103:13:29,430 of your report into huawei?
