Man down/lone worker function
TD511 include man down, lone worker function.
eg. Man down function, automatically activate and transmit an alert to call for help if the radio has been titled at a certain angle, useful if a worker has fallen injured or unconscious.
eg. Lone worker function, a warning is issued when measuring inactivity the device times out and there is no response, the alarm is triggered

IP67 Protection
TD511 Tightly sealed against wind and dust, and submersible in up to one meter of water for 30 minutes. Workers can work with confidence in challenging environments.



FCC Public Forum on Improving Sharing in the 800MHz Band Scheduled for November 6,2017



 The FCC will host a public forum on improving the co-existence of cellular and other commercial wireless licensees and public-safety licensees in the 800 MHz band. The forum will be held Nov. 6 at FCC headquarters.

In its Cellular Reform Second Report and Order adopted March 23, 2017, the Commission revised the Cellular Service power and related technical rules to provide much more flexibility in deployment of advanced broadband services and promote spectral efficiency, while taking steps to protect public safety and other systems in the 800 MHz band from potential increased interference.  Recognizing that stakeholder-led efforts on the part of Cellular licensees, public safety entities, and public safety equipment manufacturers are crucial to resolving lingering concerns about unacceptable interference to public safety mobile and portable radios, the Commission directed the Bureaus to convene a forum to foster the conversation and further good-faith efforts among representatives of these stakeholders. The forum on November 6th will include the perspectives of all three groups and various other interested parties in exploring the existing 800 MHz interference environment, realistic anticipated changes in that environment, and practical options for addressing both existing and anticipated interference problems without hindering technological advances in the Cellular Service. A detailed agenda will be released prior to the forum

FCC reject IMSA’s request to extend the certification requirement Continuing Path to Eventual 6.25 kHz Narrowbanding




Transition to 6.25 kilohertz is still in the FCC commission’s future plans. When and how the transition will happen is anyone’s guess. The most recent example is that FCC denied a request for waiver filed by the International Municipal Signal Association (IMSA). IMSA requested the certification deadline of VHF and UHF (150.80 – 162.0125, 173.20 – 173.40 and 421 – 512 MHz) LMR equipment that is not capable of operating on 6.25-kilohertz channels be extended until at least January 2020.

FCC commission announced that it would no longer certify equipment that could not operate on 6.25-kilohertz channels on Jan. 1, 2005, this deadline was later pushed back several times until it finally took effect Jan. 1, 2015. Whether or not the device has 6.25-kilohertz capability, equipment certified prior to the deadline may still be sold. But, new equipment must include the capability to operate in 6.25-kilohertz mode.


As analog technology generally does not meet the 6.25-kilohertz requirement, the commission’s certification deadline effectively required new radios to be digital. IMSA believed this to be an undue burden on public-safety users. IMSA pointed out that the commission recently eliminated the 6.25-kilohertz capability requirement for 700 MHz band public-safety equipment. If the requirement no longer made sense at 700 MHz, why continue to apply it to the bands below 512 MHz?

On June 30, the commission ultimately rejected IMSA’s arguments and issued an order denying its request for waiver. The commission stated that some comments in the proceeding claimed market competition has kept the price of 6.25-kilohertz-capable equipment comparable to that of similar equipment without 6.25-kilohertz capability.

When the transition to 6.25 kilohertz will occur? If new equipment that will need to be replaced within its expected lifetime it does not make sense to allow manufacturers to continue to certify it. Logically, if the transition is soon, it does not make sense to allow manufacturers to continue to certify new equipment that will need to be replaced within its expected lifetime.

How can an incapacitated worker can still call for help when work alone



 Many industrial and commercial communications require to capable of notifying Scenario that an employee has succumbed to a threat or environmental hazard. Man Down provides remote monitoring of workers. If somebody slips or falls, Man Down will automatically activate and transmit an alert to call for help. Man Down calls for help when your workers has succumbed to a threat or environmental hazard. An incapacitated worker who is unable to respond is therefore protected by Man Down which automatically transmits an alert for help.



How do Man Down alerts operate?
The radio activates an emergency man down alarm notification (lone worker alarm) if the radio assumes a horizontal position, degree of tilt between 30 – 90 degrees (i.e. the person carrying it falls to the floor). As to avoid false alarms for those inevitable non-emergency activities the man down – lone worker alarm transmitter will beep for a short period of time to warn the worker that an alarm is about to be activated.
 

Man Down protects every worker
A construction worker falls from a scaffolding and is knocked unconscious. A school cleaner is mopping the corridor when she slips. A security guard attacked by ruffian when on patrol. Man Down activates and an emergency alert transmits to the preset radios. He locates his worker quickly to make sure he is safe.

BelFone DMR IP67 portable radio TD511 Safely saving costs
BelFone DMR IP67 portable radio TD511 enhance efficiency and worker safety by  Mandown, Lone Worker, Blast Emergency Alarms function. The personal emergency response device comes with all of the necessary alarms and locating functions, thereby helping you to protect your employees. TD511 increase the probability that incidents get reported in a timely and efficient way.

China is becoming the pioneer of dedicated broadband for critical communications



Asia is a key market for critical communications systems. Many developing countries are investing massively in transit systems. Critical communications in the wider Asia market have developed quickly during the past decade as many countries and areas moved to digital solutions. Multiple digital technologies including TETRA, Project 25 (P25), Digital Mobile Radio (DMR) and Professional Digital Trunking (PDT) have been adopted in the Asian market.


The transport sector, one of the most active markets for critical communications, is preparing for future evolutions. Some metro companies and airports are implementing hybrid networks by using TETRA for voice and broadband for data. In many regions including Asia, rail operators are still realizing advances in cellular technology. China is becoming the pioneer of dedicated broadband for critical communications with advances in broadband trunking standardizations and dedicated network allocations.  BelFone Prochat PoC system is Push-to-Talk system that use VoIP technology over the existing cellular network to offer PTT one-to-one private calls or one-to-many group calls like two way radio. It provide half-duplex or duplex communication through a single, multifunction device.

Broadband brings significant advantages for both public-safety and cellular communications, including higher data speeds, lower latency and high spectrum efficiency. Deploying this technology on public transport enable emergency services to share interactive, allowing faster situation analysis and response times.
