Help Support RadioCapture – A Project that Records Entire Trunked Radio Systems and Provides Online Access to Audio is a website run by Matt Mills that is capable of automatically capturing trunked radio communications from various agencies such as the emergency services and creating publicly accessible historical and live logs of the audio. This is a concept different to radio scanner streams, as all audio is logged and historical audio can be accessed easily at any time.

As critical communications turn towards 3GPP, dedicated spectrum loses its lustre | PolicyTracker: Mar 2019
But more countries around the world are looking to use broadband technologies to improve their critical communications. Many of these solutions will use portions of the 700 MHz band and other frequencies identified in ITU-R Recommendation M.2015 (adopted four years ago at WRC-15), such as 380—470 MHz.

Are the Police Using Smart-Home IoT Devices to Spy on People? - Schneier on Security
"IoT devices are surveillance devices, and manufacturers generally use them to collect data on their customers. Surveillance is still the business model of the Internet, and this data is used against the customers' interests: either by the device manufacturer or by some third party the manufacturer sells the data to. Of course, this data can be used by the police as well; the purpose depends on the country. "

[pdf] Why (Special Agent) Johnny (Still) Can’t Encrypt: A Security Analysis of the APCO Project 25 Two-Way Radio System
Usenix 20, 2011
Sandy Clark, Travis Goodspeed, Perry Metzger, Zachary Wasserman, Kevin Xu, and Matt Blaze

"We found a number of protocol, implementation, and user interface weaknesses that routinely leak information to a passive eavesdropper or that permit highly efficient and difficult to detect active attacks.
"new selective sub-frame jamming attacks against P25
active attacker with very modest resources can prevent specific kinds of traffic (such as encrypted messages) from being received, while emitting only a small fraction of the aggregate power of the legitimate transmitter
"found that a significant fraction of the “encrypted” P25 tactical radio traffic sent by federal law enforcement surveillance operatives is actually sent in the clear, in spite of their users’ belief that they are encrypted"

Public Safety Advocate: Hurricane Aftermath | Andrew Seybold, All Things FirstNet, Oct 2017
via Dale Hatfield
"in the Harvey hurricane most cell sites stayed up and operational"
"in the Houston area are that most of the public safety land mobile radio and Harris County Band 14 LTE public safety broadband networks remained in operation and were heavily used during and after the storm"
Irma: "the seventh day we see only 437 sites of the 14,730 reporting still out of service"
"In areas such as the Puerto Rico it was simply not possible to pre-stage people and equipment because of dire warnings posted about Maria coming ashore as a Category 5 storm. "
"During the first days after the storm it was reported that most UHF and VHF public safety land mobile radio systems were up, or at least usable on a unit-to-unit or simplex basis"

"Houston faired pretty well with its Band 14 system (FirstNet)."
"Irma was worse. " (few details?)

"I think the lessons learned in Puerto Rico are to harden high-priority sites better and to add more battery and generator backup, but more than anything to have backup capabilities in the form of drones (UAVs), flying and stationary COWs, and satellite backhaul sooner than this time around."

"If FirstNet was up and running in Puerto Rico, would it have survived what Maria did to the island? To answer that question, you have to ask another question: Just how much money should be spent on ensuring a network is reliable even during a Maria? "

Via Dale Hatfield

"One thing everyone needs to understand, is that the failures that Public Safety is facing today is not the fault of AT&T. The quagmire within the FirstNet plan is the result of the lack of understanding and the ill-equipped commercial experience of the management team within the FirstNet organization – note I did not say the Board, but they too have some issues to face."

Public Safety Advocate: Public Safety Grade | Andrew Seybold All Things FirstNet, Sep 2017
via Dale

"What he did not say and what I hope to show in this week’s Advocate is that there are differences between public safety grade for Land Mobile Radio (LMR) sites and an LTE network. It is important for LMR communications professionals to understand these differences and not hold AT&T to public safety grade for every cell site in the network. The methodology for hardening an LTE network is different but effective and it is these differences that need to be understood."

UK LTE PPDR project “marred from day one” — PolicyTracker, Apr 2017
"As another damning report from the influential UK Public Accounts Committee (PAC) into the progress of the project is released, we reveal some of the concerns we have heard from sources close to the project.

The PAC, a group of members of parliament, said last week that it was “extremely disappointing that the [Home Office’s] risk management and assurance arrangements did not pick up earlier the risk that emergency services communications could be unsupported from April to September 2020.”"

"The transition to the new network is now not due to start until July 2018, even though the Home Office - the government department in charge of the ESN - told the PAC in November that it would start this September. Significant delays were expected by many commentators, not least because much of the user equipment does not yet exist and key standards are still in development."

"In short, if a State decides to “Opt-In”, then it will pay, with its own state taxpayer funding. What FirstNet is offering is a sheep in wolf’s clothing. For a statement to be made “that requires no additional federal funding” is a dubious, implausible and very misleading. "

Fix coming for Lancaster County's interference-plagued 911 radio system | Local News |
via Dale "The broadcast signal from a TV station in Arlington, Virginia more than 100 miles away continues to disrupt some emergency radio dispatches in Lancaster County, but a fix is on the way. About 5,800 radios of first responders in coming weeks will be reprogrammed with new frequencies that won't be susceptible to interference from the WFDC tower in Arlington or any another signal, said Michael Weaver, director of Lancaster County-Wide Communications. The weather-influenced interference has bedeviled Lancaster County's dispatches ever since the transition last year to a $26.4-million digital radio system for police, firefighters, medics and county workers.

P25 digital radio systems highly vulnerable to jamming and unauthorized decryption - Nov 2011
"On August 17, 2011 at the 20th Usenix Security Symposium, Sandy Clark, Travis Goodspeed, Perry Metzger, Zachary Wasserman, Kevin Xu, and Matt Blaze presented a paper Why (Special Agent) Johnny (Still) Can’t Encrypt: A Security Analysis of the APCO Project 25 Two-Way Radio System. These noted experts conducted in-depth research on the numerous vulnerabilities of digital P25 radio systems when operated in the encrypted and clear mode. ... According to these cryptography scientists, P25 systems are strikingly vulnerable to denial of service." "... the NID is error corrected separately from the rest of the frame. This makes it possible for an attacker to effectively prevent an entire voice frame from being correctly received by synchronizing a jamming transmitter to interfere only with the 64 bit NID field"

PPDR doubts persist about prioritisation of calls in virtual networks - PolicyTracker Jan 2016
"A Norwegian CEPT working group has issued a white paper on the use of spectrum in the 700 MHz band for public protection and disaster relief (PPDR) communications. "Actions must be taken today regarding the 700 MHz band to be able to prepare for PPDR needs in the near future,” the paper says." "One source with knowledge of public safety networks told PolicyTracker that prioritisation methods are still in their early stages and the development of voice and data on 4G networks means this will become more difficult in future. ... In addition to voice, prioritising data is also going to be difficult, said the source"

The Crisis in UK Critical Communications - Peter Clemons, Quixoticity -Martin Geddes
“LTE was not designed for critical communications.... Even the 3GPP standards bodies and mobile operators have recognised that there are serious technology limitations.” “We now have a multi-billion pound government contract that will be awarded during summer of 2015. . . . Yet there is no LTE public safety technical standard, nor will there be one for a long time.” “If we are not careful, we will find ourselves in the same situation as GSM-R. This GSM variant is a standard adapted for use on railways. It comes in just one version, with limited suppliers. The worst case scenario we now face is a fiasco: a service that is not as safe as TETRA, yet is even more expensive.”

P25: Not a One-Size-Fits-All Technology - Radio Resource Magazine: OnlyOnline - Feb 2015
By Andrew E. Schwartz -- "The National Public-Safety Telecommunications Council’s (NPSTC) twice-issued Project 25 (P25) position paper is an affront to the intelligence of all public-safety communications systems managers tasked with maintaining reliable solutions for their agencies/customers. In my home state, first responders use all common public-safety bands. They also lack, similar to most places, the funding to purchase expensive P25 equipment. Most public-safety first responders in my neighborhood still operate on conventional, and affordable, analog FM radios. This holds true for many public-safety first responders around the country."

Dead Air, Garbled Transmissions Trouble Washington State Troopers | KPLU News for Seattle and the Northwest
"Dead air, garbled transmissions and poor reception are just some of the problems with the Washington State Patrol’s new state-of-the art radio system. The $40 million conversion to digital technology is behind schedule, and having technical problems." "So far, WSP has converted three of its eight districts statewide to the new digital radio system: Vancouver, Yakima and Spokane. Over the last year, troopers working in those areas have submitted nearly 300 reports of problems with their radios, including garbled transmissions and dead spots. Knorr says some of those issues were operator error. Others have been fixed by recalibrating radios, installing better car antennas and moving repeaters to different towers. But in some places, the engineers have concluded the only solution is an expensive one: new radio towers to improve coverage."
