Intrinsically Safe Mobile Phone For Hazardous Building Construction

Intrinsically Safe Mobile Phone For Hazardous Building Construction

A job in the construction industry means demanding physical demands on both you and your Intrinsically Safe Mobile Phone. Find someone who is up to the task.

We all know that working in the construction industry means huge physical and mental demands. But have you ever thought about the damage that the average job search site can do to your smartphone? Today’s construction companies rely on many different construction management software applications to get the job done, and construction sites are dangerous places for the phones and tablets that run this critical software. Construction workers – from apprentices to supervisors – need a smartphone that has all the features and has rugged construction capabilities.

While the ruggedness of Intrinsically Safe Mobile Phone is not widely known, phone manufacturers have made rapid strides in recent years. As the construction industry has grown, the cell phone industry has begun to focus on its needs.

What is POC Walkie Talkie Function? (also known as PTT)

POC stands for Pressing on the Cell. It is not strictly a two-way radio technology, but very similar to one.

POC is a technology that uses the mobile phone network to make calls like traditional two-way radios 3G, 4G etc.

Key features;

National and international coverage
If you have access to 3G or better cellular data, you can talk to other POC devices in the 3G coverage area.

Instant sales calls
Unlike a mobile phone, you press a button and speak. There is no dialling, an almost instant connection and no waiting for the call to be answered.

When you make a call, all POC handsets hear it unlike the usual one-to-one calls.

GPS mapping.
Many POC systems allow you to see the real-time location of each POC device.

How does the PTT works.

A POC is a software application (client) on a mobile device that talks to a cloud-based POC server. The server controls the routing of POC calls to all mobile devices in the network. The mobile device can be a dedicated POC phone, any phone, tablet or desktop computer capable of running a client application.

Dedicated POC phones
By far the most convenient device is the dedicated POC handset, as functionally it behaves like a two-way radio with a PTT button and is very loud in a tough weatherproof enclosure. It is easier to use with a smartphone or tablet that has neither a dedicated button” or a “very loud speaker”.

Optional location reporting
Many POC devices have GPS receivers built into them and report this location information to the POC server in real time. This information can be considered as an online mapping using the POC mapping software.

What is Digital mobile radio (DMR) Walkie Talkie Function?

DMR stands for Digital Mobile Radio and is the international standard for two-way radios.The DMR standard allows devices developed by different manufacturers to operate together on the same network, performing all the functions defined in the standard.

DMR walkie-talkie radios have automatic digital mixed mode operation. dmr radio users do not need to switch to analogue operation mode to respond. The handheld radio is specifically designed for mission critical users. It automatically recognises the call signal and sends it in the same mode in which it was received.

The aim of the DMR standard is to create a digital radio system that is less complex and less costly, still allowing equipment from different manufacturers to work together and allowing users to shop around rather than being locked into a private system that will be expensive to replace and maintain.

The European Telecommunications Standards Institute (ETSI) is responsible for the creation and maintenance of the DMR standard. The standard was first approved in 2005 and has been updated and revised several times since then, most recently in November 2018.

How does a DMR radio work?
DMR is a TDMA mode (Time Division Multiple Access), which means it allows multiple users to share the same frequency channel by dividing the signal into different time slots. Each frequency has either slot 1 or slot 2 and each slot can be used by different users.

Do all DMR devices work together?
Yes, no. Basic functions such as voice messages are always possible. You can even use functions that are not part of the defined DMR standard if the manufacturer of choice has performed interoperability testing.

Before deciding which new product to buy, it is a good idea to check the features you currently use to see if they are unique to the current device.

What frequencies do DMR devices operate on?
Digital Mobile Radios operate on frequencies between 30 MHz (megahertz) and 1000 MHz, or 1 MHz (gigahertz). This frequency range is divided into two categories.

Very High Frequency (VHF) – the range between 30 MHz and 300 MHz.
Ultra High Frequency (UHF) – 300MHz ~ 1ghz.

Most DMR equipment falls into the 136 – 174 MHz and 403 – 527 MHz parts of the spectrum. Each country has its own organisation that issues licences for different frequencies.

Some DMR frequencies are designated as unlicensed (for DMR Tier I), while other frequencies require a licence to use.

Benefits of Intrinsically Safe Mobile Phone in the Hazardous Building Construction?

1.Provide Safe and Secure Mobile Communications
Intrinsically safe cell phones provide safe and secure mobile communications in classified or hazardous areas. You can stay connected within Class 1, Zone 1 classified hazardous areas (Zone 1/21, Zone 1, Zone 2/22). Intrinsically safe cell phones must meet specific battery design standards to achieve UL, ATEX directives, or IECEx certification for use in explosive environments.

2. Equipment Life
In manufacturing, rugged industrial handpieces play a key role in the entire value chain, from material collection, inbound and outbound logistics, procurement, demand management, order fulfillment, and manufacturing process management, to product development, commercialization, and last-mile delivery. Therefore, the first benefit of a ruggedized facility is its extremely durable and tested construction, enabling the equipment to operate under extreme climatic and operating conditions, as well as their resistance to physical shock, moisture, water, heat, and even sandstorms.

3. Inventory Management
Factory and warehouse management is essential for manufacturers. These warehouses store a variety of valuable items, parts and raw materials that can be used for a variety of manufacturing processes, machine maintenance and distribution. These along with finished goods mean keeping in an organized order and having proper accountability at all times. Did you know? rfid-based rugged devices greatly help improve inventory management by extending real-time information about goods entering and leaving the warehouse without opening boxes.

4. Maintenance machinery
The success of a manufacturing unit depends on the smooth operation of all machines to maintain the required level of efficiency in the production process. The use of industrial rugged phones has proven to be very beneficial to engineers as they allow them to seamlessly update accurate information records, share and access data in real time with managers and teams, and interact easily with customers and stakeholders. Overall, ruggedized devices improve communication, consistency, synchronization, reduced downtime, faster decision making, and increased productivity.

5. Improved process visibility
All of their work now needs to be in sync with each other, which means they need to always be told which operations need attention, which items are available, which need to be replaced or filled, which orders are waiting to be delivered, and so on. This means they need to communicate with each other at different touch points with real-time data, updates and information. Here, they take advantage of the Industrial Rugged cell phone, which allows them to communicate with each other effortlessly and instantly, and most importantly, provides complete visibility of the entire manufacturing process from start to finish.

        It depends on your local carriers .

        There are a number of contributing factors which can affect the audio performance of your device:

        The most common cause of poor sound quality is water in the microphone or speaker.

        If the handset has been subject to immersion in water then the microphone and speaker may need to dry out to resume normal functionality.

        You, or the other person you are speaking with, maybe in an area of poor signal. Try moving to a different area.

        You may have dirt/debris covering the microphone or speaker. If so, clean your device.

        Check your order status or check it through
