the legal team of brazil's former president lula has asked the supreme court to suspend his 12—yearjail sentence for corruption. it comes just hours after he was due to hand himself into police. he has been holed up in the headquarters of a steelworkers‘ union. doctors treating the former russian spy who was attacked with a nerve agent in the uk say he's no longer in a critical condition. sergei skripal and his daughter yulia were found unconscious on a park bench in salisbury, nearly five weeks ago. russia has threatened a tough response to new us sanctions imposed on russian officials and companies, who are accused of profiting from president putin's efforts to undermine the west. the blacklist includes mr putin's bodyguard, his son—in—law, oligarchs close to the president and a dozen companies they control. coming up a bit later in this half hour, newswatch. but first, it's time for click. well, here in bournemouth, ag is somewhat underwhelming to say the least.

welcome to bournemouth on the south coast of the united kingdom, famous for sandy beaches, seaside amusements... and having the worst ag mobile reception in the uk. i hate it. it's not good in anywhere, really. it's very, very temperamental and really, it's really not good. well, there's some good news. 56, the next generation of mobile network, is coming. but it's notjust about your phone. sg promises to enable self—driving cars, smart cities and the whole internet of things as every machine starts talking to every other machine. this week, the first stage of bidding to become a 56 operator in the uk ended with ee, 3, 02 and vodafone splashing out more than £1.3 billion for the privilege. now, to date, no standards have been agreed, but we do have a rough idea of what 56 should look like. so, let's get you sg—ready. five things you need to know about 56. one — yes, 56 will be much, much faster than ag. hd movies can be downloaded in seconds rather than minutes

with speeds 10 to 100 times faster than ag. two — unlike ag masts, which broadcast in all directions, 5g antennas will send concentrated beams directly to your device. three — 5g is all about superquick response times and that's crucial for things like self—driving cars, which will use the tech to communicate with each other at high speeds. four — it's a new wave. 5g will use a part of the radio frequency spectrum that's never been used before, meaning it will broadcast on shorter millimetre waves. that means more data for all those devices. but there is a problem. these waves can't travel through buildings or even rain. five — the solution is new masts masks and lots of them. but the good news is that they only need be tiny. these mini masts will need to be much closer together and they'll act

like a relay team transmitting signals around buildings. 5g projects are still being trialled, and the kinks in the technology are still being worked out. but lara lewington has been to see what is claimed to be the world's first public 5g testbed. the trial taking place here in bristol's millennium square aims to give the public an idea of what 5g could make possible. this communal virtual reality experience shows streaming of high—bandwidth content on many devices all at once, all on one network with no time lag or drop out. dancing in unison, we played a game involving chasing moving stars. these demos couldn't be in full 5g because current smart phones can't oblige, but every other element is there, with these 5g new radios throughout the area transmitting signal. the team here anticipate 5g to be

a network of networks, combining the best elements of conductivity we have now with millimetre or extremely high frequency waves, plus the potential to tap into wi—fi networks and li—fi connections, particularly when we're on the move. we've talked a lot on this programme about the possibilities for smart homes, connected transport and of course, smart cities, and 5g could provide the catalyst for more of them to actually come into play. this prototype aims to display one way that 5g could be used within a smart city. now, what you can see on top of this cycle helmet is a 360 camera, a raspberry pie, which is doing the work, and a battery pack right here. the idea is someone cycling throughout the city would be constantly picking up pictures and they would be fed through a 5g network, so if there was any problem, that could be found immediately and dealt

with without delay. and if we can rely on that low latency, then it's game changing. when it comes to robotic surgery, a split second could mean the difference between life and death. or it could be used to create realities that seem almost impossible, like anyone being able to shoot a goal like messi via a 5g connected robot leg, off course. using 5g technology ultra low latency technology, i'm able to transmit action and reaction. i am able to transmit touch. so, for the first time, we will be able to transmit engineering skills, musical skills, football skills, medical skills, and suddenly, we will build an internet which will allow us to democratise labour the very same way as the internet has democratised knowledge and information. for most of us, though, we just want better connection, and the networks seem keen to manage our expectations beyond that. the average person on the street

will see 5g as a way to get them a much better smartphone experience, it will give them faster data connections, lower latency. but it's important to remember that we're right at the start of the 5g journey and we need to look ahead over the next decade to understand what new applications beyond smart phones will start to appear as the technology matures and becomes more widespread. south korea, the us, the uae and china seem to be leading the way with commercial launches expected later this year. but in the meantime, smart phone manufacturers will be working on bringing us the 5g compatible devices that we need for whenever the time comes. that was lara in bristol. well, here in bournemouth, ag is somewhat underwhelming to say the least. so we've been asking people what they think about the arrival of 5g. perhaps there are lots of exciting things that we don't know about, in which case i say bring it on, bring it to bournemouth first.

it doesn't light any fires for me! i can see it being useful for me in about ten years, when i catch up with the rest of society. i still think about...is in 36? 36 for me soon, and i'll be pleased with that. so, a bit ofa mixed reception for 5g so far here. nevertheless, the local authority is aiming to make bournemouth one of the first places globally to deploy 5g and become the first smart city, technically smart town, in the uk. heading up the implementation of 5g is ruth spencer, who took me on a tour to show me some of the new cabling and potential antenna sites that will underpin what will be a radical new infrastructure. ag to 5g is going to be a massive step change in infrastructure. so, for example, in ag, what you would have had before is big masts, quite long—distance parts... covering a large area. whereas with 5g, particularly in urban areas like this, you'll need lots of small cells very close together.

that's a massive infrastructure challenge, isn't it, if you need lots and lots of masts to cover a city. i think what we're trying to do at the moment is understand how cost—effective that it is going to be to deploy at this kind of level. it sounds like a massive ask. is it realistic? it is a big undertaking. but the potential that 5g is going to unlock is going to be completely transformative. now, the problem is the 5g signal is very fragile, easily blocked by trees and buildings and that means that ruth's team has had to produce really detailed surveys of where the antenna need to be. whenever you put a new building up, it interferes with the 5g array of signals that you've got. so that's a problem. yes, yeah, it's a challenge that definitely needs to be looked at. so with the map and planning

software that we've been developing, we need to start considering how do we update those tools and how do we update the maps that we're looking at in order to plan those networks. but it's the potential that may make the investment worth it, as 5g will be the backbone of all those futuristic technologies that we've been long promised. and so 5g isn't necessarily about getting better signal on your phone or faster data speeds on your phone. it's about machine—to—machine communication. in machines, in advanced manufacturing, in robotics. so it becomes much more about the opportunity 5g will bring around productivity, as well as the ability to deliver services. for 5g to work, serious investment and new infrastructure is needed, so could it be that some cities will be flush with transformative technology, while other places will be left behind? i get the sense we might be about to see the beginnings of a new digital divide where some areas have 5g and some areas don't.

for example, rural areas where there's a small population, so itjust might not be worth it. but does that mean they miss out? whilst 5g is likely to be rolled out at a millimetre wave level in cities, there's still the opportunity for rural areas to really benefit from 5g in other areas, like farming, connected autonomous tractors, for example, and you would need some 5g infrastructure to support that, but you would need something different in a city. it's about understanding what's needed for users in which locations and what's needed for infrastructure in which locations. we're talking about autonomous vehicles being able to take you anywhere. but if it turns out they need a 5g network, and you roll into a city which doesn't have a 5g network, what will that mean for your autonomous vehicle? will it not be able to operate in that city? so one of the areas that connected autonomous vehicles are looking at is where they will be deployed and what their use will be,

so, for example, in the early stages, maybe you'd be looking at connected autonomous vehicles across motorways, for example, for covering long distances, with freight or that sort of thing, and then it will evolve. and that's it for the shortcut of click in bournemouth. don't forget the full—length version is waiting for you right now on iplayer. and also don't forget we live on facebook and twitter @bbcclick. i have to say, this place might be the worst in the country for ag but it's one of the best places for fish and chips, so that's where we're going now. seeya. hello, and welcome to newswatch with me samira ahmed. bbc news says it's aiming for a 50—50 gender balance of expert contributors to its programmes. we ask how and why. and well and truly got out.

how bbc breakfast presenters fell for an april fool in the papers. first, the row overjeremy corbyn‘s response to an anti—semitic mural was widely covered on bbc news last week. there were further criticisms this week over the labour leader's handling of abusive anti jewish messages on facebook and on tuesday then write reported on mystical than‘s attendance at passover dinner organised by the left wing group, jewdas. do you regret going to that in a last night? not in the slightest. in politics every choice matters, decisions sent a signal and jeremy corbyn‘s choice to organise a passover event celebrated by a left—wing group has brought about anger in the broader jewish community. in the last fortnight hundreds of viewers have contacted the bbc saying the issue of anti—semitism in the labour party has been blown out of all proportion.

steve williams wrote on wednesday: and susan parks agreed: the bbc has also reported on the spate of violent crime in london, with more than 50 killings in the capital this year, one victim of a drive—by shooting on monday was 17—year—old tanesha melbourne whose death was covered by a dealer campbell. —— adina campbell.

speaking exclusively to the bbc tanesha's brother says the family are devastated. i'd just come up from university, like, i didn't have a clue. tanesha, she was just in the wrong place at the wrong time, i don't have a clue, man. when did you get to see her afterwards? i saw her today.
