  1. MPs have blasted the government's lack of a robust contingency plan to tackle the delayed deployment of a new Emergency Services Network (ESN)—warning that it represents a "potentially catastrophic blow" to 999 responders and could be "a tragedy in waiting." For something that is meant to be in use shortly I'm yet to hear any positive news. I am inclined to agree with the headline and the rest of the article.
  2. Push-to-talk functionality on the London Underground has been a hard won police radio capability, but its future on the new LTE network faces serious hurdles. Gary Mason reports. It is somewhat ironic that in a multi-billion pound public safety communication project investing in cutting edge long-term evolution (LTE) technology, a major sticking point is the reliability of push-to-talk voice messages – a capability that has been around since the days of analogue police radios. This is just the latest problem facing the Emergency Services Network (ESN) project, which at least two recent reports have predicted would not be ready on time. This means the existing system, Airwave, is expected to be maintained for an unknown period after its expensive contract with the Home Office and the UK’s blue light first-responder services expires. Police concerns about the voice function on the new LTE handsets, whenever they emerge, have been highlighted in the latest Public Accounts Committee (PAC) report, published in January. Push-to-talk allows users to contact their colleagues with only the press of one button. The function must be reliable and work in remote areas – not just rural environments, but also the underground tunnels of the metro systems in London and Glasgow. Devices with the appropriate levels of robustness, voice and dual-mode capabilities are currently under development. The Home Office told the PAC it had already received prototype devices and was confident a good selection would be available for users to choose from by next year. But the devil, as usual, is in the detail. Some of the technical challenges in developing mission critical push-to-talk capability on LTE handsets were spelled out in oral evidence to the committee. Under the terms of the ESN contract with the Home Office, Motorola Solutions is responsible for delivering user services, such as data centres, help desks and SIM card management. While the scope of its contract does not include devices, Vincent Kennedy, vice-president and general manager of Motorola Solutions UK, gave the committee an insight into some of the technical challenges that had emerged with prototype LTE handsets. Push-to-talk latency The ESN envisages two types of device that will run on the network: 4G data devices and voice devices. The 4G handsets can attach to the new network relatively easily, but voice handling is more complex. “When you move the voice service on to a commercial mobile phone network, the device has to act in a specialised way,” Kennedy told the committee. “If I picked up my phone and dialled your number, it would take a few seconds to ring. It might take six seconds to you or five seconds [to someone else]. In this world, when I am the commander of a team at a firearms incident and I press the button on the device and say, “Don’t fire”, you instantly all have to hear the same thing. It is a big problem if you hear, “Don’t fire”, and another person hears, “Fire.” That is just an example, but the voice piece makes the device more specialised, and it has to work in a special way.” The technical term for this issue is push-to-talk latency. Police using the system need to be confident that the latency can be low enough with 4G that it won’t be a problem, and that the voice message received by everyone during an incident will be as near to instantaneous as possible, which it isn’t right now. Kennedy said Motorola been investing in the research and development of mobile LTE technology for public safety since 2010. He said: “It [LTE] is where the public safety market is going. They will eventually all be using mobile broadband, mobile data and voice. If it works to design, the latency can be solved, but that is why the design is so strict around the devices and the network.” He told the committee that the latency issue can currently be proved in a lab environment, but it needed to be tested in the field under extreme conditions. A testing regime will continue all through the spring and summer. Operational trials could commence in the autumn of 2017 and will go on for several months. “These are big technology projects, but they are not like regular IT projects. The people who use this technology – their lives depend on the technology working,” he added. The example Kennedy gave during the committee hearings bears a chilling reminder of the shooting of electrician Jean Charles de Menezes by Met firearms officers in July 2005 at Stockwell underground station after he was mistaken for a terrorist suspect. At the inquest into the killing, a firearms officer told the court he could have missed important messages over the radio and told the inquest that the signal was weak, faint and fuzzy and would sometimes cut out altogether. Given such real life examples, why has the Home Office chosen to go with unproven technology? In a previous report published last year outlining problems with the ESN project the National Audit Office said that it is ambitious and the first of its kind in the world. A world first Other countries are pursuing solutions either fully or partly based on older terrestrial trunked radio (TETRA) technology and dedicated networks, such as Airwave. The Home Office told the PAC that, in an ideal world, it would not want to be first to adopt unproven technology. But it considered that the other options it had for replacing Airwave, such as a hybrid system that uses radio for voice communications and 4G mobile for data, were “equally risky” and that it had to consider a wide range of financial, operational, technological and legal factors when making its decision. The programme also faces a number of other technical challenges. The new system will operate across a commercial 4G network requiring new software to allow emergency services users priority over commercial customers. EE, who have been awarded the network contract, told the committee it had completed system testing to prove the prioritisation technology would work and that during an emergency its network would be able to prioritise all 300,000 emergency service users, if necessary. Meanwhile, Motorola has responsibility for setting the specifications and approving devices for use on the ESN. Since it is also a supplier of devices, the Home Office told the PAC committee it had “been very careful to make sure the specifications do not exclude other providers and are not bespoke. It is a standards-based process”. One of the biggest risks with the new system is ensuring coverage in remote areas and in hard to reach places, such as the London Underground. The Home Office says that using 4G mobile data technology instead of radio opens up more options for plugging gaps in coverage, such as by using temporary masts. Time is a factor Discussions are still ongoing between the Home Office and Transport for London (TfL) on how best to extend coverage into the Underground, as well as contingencies and options for the transition process. The Home Office hopes to make an announcement in the next couple of months on this issue. Time is a factor, since the rollout of the ESN is just two years away. If TfL cannot roll-out the technology in that time, the Home Office would need to agree an alternative solution with TfL. This is a crucial issue for the police and fire service in London in particular, as a fully functioning emergency services communications system was a hard fought and long awaited upgrade. The lack of such a system was first highlighted by the inquiry into the response to the King’s Cross fire in 1987. These concerns were then reiterated after the 7 July 2005 terrorist attacks, which centred on London’s transport system. Airwave was eventually rolled out fully in January 2009 to all 125 below ground London Underground stations. This meant that British Transport Police (BTP), the Metropolitan Police Service (MPS) and the City of London Police are able to use the same radios underground. The rollout linked the emergency services network to London Underground’s Connect digital radio system, part of the Transport for London’s £10bn investment programme. Natural disasters The vulnerability of city subway systems not just to terrorist attack, but also to natural disasters is well documented. The need for a robust emergency services communications system that links into the network operated by the transport authority is also well recognised. When Hurricane Sandy swept through the New York metropolitan area in October 2012, it left behind extensive damage to New York City Transit facilities throughout the subway system. A record storm surge inundated tunnels, filling critical operations rooms that housed electric equipment for signals, relays and communications with highly corrosive saltwater. The storm also exposed a need for a better and faster way for supervisors to communicate with crew members and customers in times of emergency. Even after three years and thousands of hours of labour spent repairing and restoring service to pre-Sandy levels, the subway system has yet to fully recover, with many related repairs still to be made. In 2015, MTA New York City Transit received two Federal Transit Administration grants totaling $57.1m (£45.7m) for two major storm resiliency projects in subway stations: a new emergency communications system and a hardening project to protect station rooms critical to service delivery. Until March 2016 police officers in the transit system could only communicate with each other underground because police were on two different radio frequencies. Using a $100m grant, mostly spent upgrading existing technology, all officers’ radios were reprogrammed to allow them to communicate over ultra-high frequencies on the street and in the subway. Their use was delayed for years, mainly for reasons that had nothing to do with technology, but bureaucratic inertia. Read on Police Oracle
  3. http://www.mobilenewscwp.co.uk/2015/12/10/ee-wins-7-billion-emergency-services-contract/ Call me cynical but I'll be looking for this to come in behind schedule and over budget.
  4. Cumbria constabulary has spent £1.8m on state-of-the-art handsets for its 1,130 frontline officers, to replace the traditional policeman's notebook. But top brass have been left red-faced after it emerged that just 11 per cent of the rural county has high-speed mobile internet coverage. That means officers on foot patrol in country communities will have to rely on slower 3G speeds to record crimes - if they can get online at all. Critics reacted in disbelief at the news, which has been branded "mad" at a time of swingeing cuts to police budgets. The handsets have been bought so that officers can fill out routine paperwork for minor crimes, such as anti-social behaviour, whilst out and about without having to return to a police station. However, doubts have been cast on how that will work after official figures published by Ofcom revealed that 89 per cent of Cumbria has no reliable 4G signal. While the other 11% does have high speed internet, provided by EE, nearly a quarter of the county is also said to have no reliable access to even slower 3G speeds. The figures date from June last year and are the latest available from the communications watchdog. Jonathan Isaby, Chief Executive of the Taxpayers' Alliance, said: "There's nothing wrong with embracing new technology, but buying 4G phones for an area in which 4G is more a theory than a reality is mad. "Taxpayers will wonder if this money could not have been better spent by the police force at a time when every single penny is so valuable." This map shows the sporadic 4G coverage in Cumbria Mobile phone coverage maps show that the vast majority of the 4G coverage in Cumbria is centred around the county's main towns of Carlisle and Barrow-in-Furness, with precious little in between. Despite this the force has teamed up with mobile network EE to provide all frontline officers and some backroom staff with taxpayer-funded Samsung Galaxy Note 4 handsets, which retail for £569 each. A spokesman said the move will save £3.3m over the next three years and will free officers up from endless paperwork, meaning they can spend more time out on the streets. EE was the first UK network to bring 4G to the countryside when it launched the service for 2,000 homes and businesses in Cumbria in autumn 2013. At the beginning of this year it brought a new micro network in the county, where individual households host small mobile antennas to boost the signal in rural areas. Announcing the deal, which has been backed by the local Police and Crime Commissioner and the Home Office Innovation Fund, Chief Superintendent Steve Johnson said: “Cumbria Constabulary polices one of the largest geographical areas in England and Wales, which covers difficult terrain. "As a result, call and data coverage and communication quality are important factors in mobilising the workforce in order to increase the amount of time officers are able to spend in the community, keeping people safe and dealing with crime. "The increased mobilisation of our officers involves the completion of documents outside police stations. "The EE data super-bundle provides value for money for Cumbria Constabulary, as all officers and staff are able to utilise the data with no wastage and no extra monthly costs.” http://www.express.co.uk/news/uk/585365/Cumbria-Police-spends-millions-Samsung-Note-smartphones-no-4G-in-countryside This is why in my opinion the proposed replacement of Airwave with 4G ESN starting next year is not currently viable.
