World-Class Stadium Wide Communication Solutions
With the changing threat landscape, it’s never been more important for operators to update risk assessments and operational security to reduce the risk of accidents, petty crime, anti-social behaviour, public disorder and acts of terrorism at stadiums and multi-purpose arenas.
With tens of thousands of people attending stadiums and arenas for sport and entertainment events, the challenges facing safety offices and emergency services management, are both large and complex. Maintaining robust safety and security processes while managing the efficient flow of spectators, participants, VIPs, vehicles, goods and services at multiple entry and egress points, especially in the event of a major incident, pose major logistical challenges.
In most cases the burden of responsibility to ensure compliance with legislation, best practice and the safety and security of everyone in the stadium rests with the Safety Officer. One of the key requirements is the ability for the control room to communicate with Safety and Medical Officers, functional teams and the emergency services instantly, reliably and effectively anywhere within the stadium and its grounds.
TWO-WAY RADIO SUPPORTING STADIUM AND ARENA OPERATIONS
Analogue license-free PMR446 and licensed radios have been proven in service at stadia and events around the world for many years, however, more and more facilities are upgrading to KENWOOD NEXEDGE NXDN and DMR digital conventional and trunked two-way radio solutions to provide instant, clear, multi-user voice and data communications and the flexibility to design scalable digital radio communication systems to suit coverage, worker safety, capacity and operational requirements.
Typical applications include:
- Liaison with control room
- Coordinating surveillance and intelligence operations
But it is not just at large, high-profile events that radiocommunication comes into its own. Smaller crowds attending club level rugby and soccer matches, athletics meetings, shows and concerts also benefit from the support two-way radio brings to everyday stadium and arena operations from catering to maintenance, cleaning and facilities management.
BENEFITS OF TWO-WAY RADIO
In an age of smart, connected devices including mobile phones, tablets and hybrid LTE/PoC radio, what are the advantages that digital two-way radio brings?
It’s an often-asked question.
Robust, low purchase cost and with no dialling, waiting for a connection, dropped calls, service contracts, call or data charges are just some of the benefits - providing instant voice and data communications at the push of a button indoors and out without unnecessary distractions.
Hand-portable two-way radios (walkie-talkies) can provide one-to-one, group and all users communication options, giving you the flexibility to build a radio system that will underpin your operations whether it’s calls between management, security, medical teams or stewards, or alerting all team members anywhere on site in the event of an incident requiring assistance.
Put simply, think of two-way radio as the communication tool of first and last resort; connecting individuals and groups instantly at the push of a button and continuing to work even when mobile networks get overloaded or IP connections fail.
KENWOOD RADIOCOMMUNICATION SYSTEMS WITH WORKER SAFETY FEATURES
Being equipped with a reliable two-way radio gives staff the reassurance they need to work more confidently, under less stress and with greater efficiently - secure in the knowledge that should an accident, medical emergency or incident occur, their radio ensures they’re never more than the push of a button away from help.
ProTalk License-Free PMR446 – simple and effective
The simplicity and convenience of analogue and digital license-free PMR446 technology has made it a popular choice in smaller stadiums and arenas where its reliability, ruggedness and ease of use has provided instant communication between individuals and groups over shorter distances at the push of a button.
Digital dPMR446 is by far the most popular format with professional users. It offers better reception to the full extent of the coverage area and is particularly suited to operations at smaller stadia and arenas. Durability, a long battery life between charges and simplicity of operation in all conditions are some of the key attributes of the current generation of KENWOOD ProTalk digital dPMR446 radios, along with many more advanced features only previously found in licensed radios.
The ProTalk TK-3701D for example is better built and equipped than most and offers native analogue to digital mixed operation, a second programmable PTT button, 32-digital and 16-analogue channels for congestion free operation even in cities, ease of use, durability and a long battery life between charges. For an entry-level radio offering the capability of one- to-one and call-all-radios feature, there’s little to better it.
Licensed DMR and NEXEDGE NXDN radio systems
For large stadiums and arenas or events taking place across multiple locations, a licensed KENWOOD digital radiocommunication system brings even greater benefits, including:
- Individual, group and all radios calls
- Programmable automated alerts
KENWOOD DMR and NEXEDGE NXDN digital protocols both offer the capability to build flexible and scalable systems suitable for covering single or multiple sites for example off-site training facilities, while the native analogue/digital Mixed operation feature (enabling radios to communicate automatically with existing licensed analogue radios), provides a predictable, economical migration path to digital two-way radio operation at an affordable cost and the basis on which to build a scalable, future-proof radio system.
A KENWOOD DMR or NEXEDGE NXDN system equipped with GPS devices not only provide multiple communications channels and talk groups but also, with the addition of the optional KAS-10/20 software or Trackuracy ‘asset’ tracking suites, allow you to monitor and track every radio so you always know where staff are and can pinpoint and alert those closest to an incident to reduce response times.
Advanced safety features of KENWOOD DMR and NEXEDGE NXDN radio systems
In addition to the efficiency that radio communication brings to coordinating operations, it also serves to help you comply with health and safety and security requirements/regulations, for example, alerting staff to the presence of threats, calling for medical assistance and reporting incidents and accidents.
However, where radio communication really excels is in the event of a major incident. Whether that be a medical emergency, staff at risk or a more serious event that requires key staff everywhere on site to be alerted instantly and to initiate emergency, lockdown or evacuation procedures.
All KENWOOD DMR or NEXEDGE NXDN hand portable and mobile in-vehicle two-way radio devices feature an Emergency Key and Emergency Call features as standard, while more advanced models additionally offer built-in or optional GPS modules, Lone Worker, Motion Detection and compatibility with Location services, which make them suited for incorporation in a robust health and safety policy.
Once programmed and activated, these advanced safety features can include:
The Priority Call feature ensures the availability of a radio channel in the event of an emergency and allows a dispatcher to interrupt all existing calls on a channel.
An alarm is triggered along with the user ID of the sender and when the Emergency Key button is pressed. GPS equipped radios can additionally send the location (GPS coordinates) of the user.
An alarm is triggered along with the user ID of the sender if a user does not respond to a status prompt within a specified time.
An alarm is triggered along with the user ID of the sender if the radio is tilted beyond a pre-determined angle indicating that the user may have fallen or become incapacitated. Other programmable features include:
- Stationary Detection: Emergency mode is triggered along with the user ID of the sender when the radio remains in a stationary position for a period exceeding a pre-set time, indicating that the user is unable to operate the transceiver, or it’s has been lost, mislaid etc. GPS equipped radios can additionally send the location (GPS coordinates) of the user to a control centre using software such as KAS-10 and KAS-20 AVL and Dispatch suites.
- Motion Detection: Emergency mode is triggered along with the user ID of the sender when the radio is vigorously shaken or swung for a period exceeding a pre-set time, indicating that the user is running to or from an incident. GPS equipped radios can additionally send the location (GPS coordinates) of the user to a control centre using software such as KAS-10 and KAS-20 AVL and Dispatch suites.
|Automatic Injury Detection:||
NX-3000 & NX-5000 Series Radios: Should an officer be shot, stabbed or struck by shrapnel while wearing a Bluetooth body-armour vest, an ‘Emergency’ alarm is automatically activated and reported to a control room console equipped with a KAS-20 AVL/Dispatch or similar suite.
|Heart Rate Status:||
NX-3000 & NX-5000 Series Radios: A programmable function for monitoring the health of field officers. When the Heart Rate Status feature is enabled, the GPS data sent from the transceiver includes the heart rate (status) which is reported to a control room console equipped with a KAS-20 AVL/Dispatch or similar suite.
NEXEDGE NXDN and DMR radios equipped with GPS can additionally be programmed to send location information to the control centre using software such as KAS-10 or KAS-20 AVL and Dispatch suites so that the user at risk can be located quickly and response times reduced.
|Asset Tracking and Monitoring:||
With Trackuracy, KENWOOD DMR and NEXEDGE NXDN systems can be equipped with low-energy, real-time asset monitoring and tracking across single and multiple sites, indoors and out. Alerts and alarms delivered as audible tones, voice or data messages can be programmed to trigger automatically should the user stray off course or enter restricted areas.
Remote Monitor allows control centre staff to listen in to a radio through its microphone in situations where an alarm is activated, and the radio user is unable to respond. This provides the Safety Officer with the intelligence to assess a situation in real time and to quickly initiate an appropriate response.
EXCEPTIONAL AUDIO QUALITY EVEN IN NOISY ENVIRONMENTS
Background noise is a big issue for communications in stadiums and arenas. During a football match, noise levels can reach up to 90db while at a rock concert, levels can rise to 120db, making voice communication challenging. Effective noise cancellation results in clearly audible voice communication irrespective of the level of background noise, a crucial safety and security requirement in managing crowds, especially in the event of a major incident.
KENWOOD radiocommunication devices benefit from JVCKENWOOD Group’s 60-years’ experience in producing consumer audio and visual equipment (Trio, JVC and KENWOOD), renowned for exceptional sound quality.
This transfer of knowledge and experience has led to the development of a number of novel and innovative solutions which overcome the problem of cancelling ambient noise while improving the audio clarity of the transmitted voice - in any operating environment.
|Ultimate noise cancellation:||
NX-5000 Series hand-portable radios achieve optimum noise cancellation with the use of two integrated microphones. The main microphone is situated closer to the desired source (front of the radio), while a second microphone in the rear of the radio receives the ambient noise. In a noisy environment, both microphones receive noise at a similar level, however, the main microphone receives the user’s voice more strongly. The processor in the radio subtracts one noise source from the other so that most of the ambient noise is cancelled which effectively enhances the quality of the transmitted audio of the user’s voice.
|Active Noise Reduction:||
Both NX-5000 and NX-3000 Series radios feature Active Noise Reduction (ANR). ANR serves to cancel the noise component of the collected audio to improve the transmitted audio quality.
Noise cancellation functions can be ‘Custom’ configured to adjust the vocoder, DSP, filters, specific noises etc. to suit the operating environment.
|Selectable Audio profiles:||
The received audio will sound different depending on the usage environment of the radio, characteristics of the device (such as the microphone to be combined with the radio and external devices), and the tone of voice and manner of speaking of the speaker. The received audio will also sound different depending on the output method, such as using the speaker of the radio or via an earphone, to hear the received audio. KENWOOD radios feature 6 customisable audio profiles which can be configured for specific scenarios and selected by the user to suit the operating environment.
COST-EFFECTIVE MIGRATION FROM ANALOGUE TO DIGITAL
The beauty of a KENWOOD digital two-way radio solution is that your investment in new equipment when upgrading from analogue can be phased over time as all KENWOOD digital radio devices feature automatic analogue/digital Mixed Mode operation (which allows them to communicate automatically with any existing analogue radios whatever the make) providing a predictable and cost-effective path to full digital implementation.
BUILT TOUGH TO WITHSTAND RAIN, DIRT AND THE ROUGH AND TUMBLE OF USE IN STADIUMS AND ARENAS
Radios used in stadium management need to be robust, able to operate constantly for long periods and in all weather conditions.
As you would expect, all KENWOOD professional hand portable walkie talkies and mobile radios conform to MIL-STD-810 C/D/E/F/G for ruggedness and durability and are IP54/55/67 Water & Dust Intrusion rated, making them suited for use in any environment.
In addition, KENWOOD can offer ATEX IECEx devices for use in hazardous, explosive atmospheres.
SECURITY & PRIVACY
As more products are connected by IP and to networked information and automation systems, there is a growing risk of leakage and theft of personal and other information, fabrication or destruction of data, and hijacking of products.
Secure encryption is an essential requirement in radiocommunications to provide security against eavesdropping, jamming and other malicious attacks on a radio system.
All KENWOOD digital radio devices are equipped with a voice scrambler as standard, while licenced NEXEDGE NXDN and DMR radios are further protected with more advanced encryption:
Voice inversion scrambler
Built-in digital scrambler as standard, optional upgrade to ARC4 Encryption for DMR
