Innovative radio solution protects and preserves Chinese forests

We all know how important radio communications are, and Motorola Solutions have captured a massive coup by providing the radios for protecting the Chinese forests, a feather in the cap for Motorola because Hytera, their biggest competitor at the moment, originating from china, interesting! We found this article on this website.

Motorola Solutions (NYSE:MSI) with its channel partner Beijing Dyne Rcomm Technology are helping to keep China’s Hunan forestry region safe with a MOTOTRBO digital radio system that increases safety and security for employees while helping them to work more efficiently.

China’s Hunan province is rich in flora and fauna resources that are essential to the region’s economy. However, these vast areas which make up around 60 percent of the province’s total surface area can be risky places to work for forest rangers. Forest workers depend on reliable communications to be aware of potential bushfire risks and other emergencies.

The innovative radio system integrates MOTOTRBO digital two-way radios and repeaters, a dispatch console for centralised control and monitoring of the network at all times and Motorola Solutions’ IP Site Connect digital solution to extend radio network coverage over the internet throughout the counties and cities.

“Rangers depend on access to clear and reliable communications. They need to stay constantly connected to their colleagues working in control rooms who have visibility of the entire operation and can help to keep them safe at all times,” said Michael Jiang, China President and Country Manager, Motorola Solutions.

“It’s absolutely essential for forest rangers to know where their co-workers and resources are at all times, especially in times of emergency.

“Hunan’s new radio network provides extensive coverage throughout the region, enabling rangers working across a wide geographic area to report the very first signs of fire so that resources can be deployed quickly and effectively to protect lives and natural resources,” Mr Jiang said.

Hunan’s integrated system connects the surrounding cities and counties through clear voice communications enhanced with noise cancelling features that perform reliably in the nosiest environments. This system also supports data transfer across the radio network, using GPS to pinpoint the location of nearby team members and resources in emergency situations, while text messages and automatic alerts can be sent between the province’s central control room and radio users in the field.



Motorola Solutions has now deployed more than 5,000 radios to major forestry projects across greater China at locations including the Inner Mongolia, Hebei, Liaoning, Sichuan and Guangdong provinces.

Who Actually Conceived The Radio Headset

Have you ever stopped to think where headsets really came from? Well, they first headset was used in the 20th century; however, the technology has significantly improved over the decades. Shockingly it did not occur to anyone that headsets could be used to listening music on devices. Read more about the invention of radio headset in this article.

Everyone Uses Headsets

Headsets are an important accessory and it is very clear that they have indeed managed to save an argument over the years. Headsets enable you to listen to audio/music without having to get in the way of anyone else. In this time and age, we use all types of headsets from tiny earplugs with a wireless Bluetooth technology for listening to music in the streets, to big leather-padded cans to listen to music at home. Gaming headsets are increasingly becoming popular as many of them today come outfitted with a microphone, hence allowing the users to speak with other relatives, gamers and friends.

Headsets can give the user a great sound quality, there isn’t any sort of interruption between the ear and the sound, external sound is blocked out and there is absolutely nowhere for it to dissipate, more so if you invest in a pair of high quality headsets which are plentifully available nowadays. As a matter of fact, if you take a walk back to the early 20th century right before amplifiers had been invented; sensitive headsets were the only means that was could be used to listen to music/audio.

What Year Was The First Radio Headset Invented?

Accurately speaking, the very first headset dates back to the telephone early adoption and by 1920 radio headsets were being commercially manufactured. These were mainly used by professionals and not by the public. There exists an argument over who was first person behind the idea to dwindle down loudspeakers and move on to attach them on our heads but the earliest living example dates back to around 1911. This was far from the headsets we use presently with no padding for comfort and a very low sound quality. They were used by telephone exchanges and radio operators.

Who Invented The Radio Headset?

Headsets were the only way to listen to audio files before the development of amplifiers. Headsets were invented in 1910 by Nathaniel Baldwin, an American born to a Canadian father and an American mother. Baldwin developed the first, truly successful set in 1910 by hand in his kitchen and later sold them to US Navy.

Baldwin’s headsets made use of moving iron drivers that came with either balanced or single ended armatures. The requirement for high-sensitivity meant damping could not be used, and hence they had a crude sound quality. These early models did not have padding, and oftentimes ended up producing excessive clamping force on the heads of persons wearing them.

In 1944, John C. Koss a jazz musician and an audiophile from Milwaukee, US, designed the first stereo headset. Previously, headsets were used only by radio and telephone operators, as well as persons in related industries. The 3.5-mm phone connector and radio headset, which is commonly used in portable applications today, has been in use since the Sony EFM117J radio that was released in 1965.

Two way radios that can be submersed to 1m, that will be the IC-F2000

Icom two way radios are well known in the marine and coastal industries. Why are these so well known in these industries? That is because the F1000 and F2000, along with the F1000D and the F2000D are all waterproof, being able to be submersed to a depth of 1 meter for a maximum of 30 minutes, that means that these radios can be used confidently on a boat, ship or other water fairing vessel and be splashed around before it starts smoking and sparking everywhere! The IP67 waterproof casing means that it is made for total protection against dust and dirt and can withstand immersion between 15cm and 1m.

When we talk about sound, we expect the highest quality of two way radios to have the best speakers producing the best output possible, but the icom website explains it like this “The large 36mm speaker of the transceiver provides clear commanded 800 mW audio. The built-in BTL amplifier doubles the audio output power and delivers loud and intelligible voice to a radio operator working in noisy environments” which basically means it produces some of the best sound out one of the smallest speakers on the market.

So let’s go over the radios themselves, something that isn’t so obvious is that they have split the frequency bands of the radios, the F1000’s is VHF only and the F2000’s is UHF. This is a brilliant idea from the guys at Icom, users often find it difficult to wade through a lot of the jargon of two way radios, so separating out the radio types into their respective bands goes a long way to remove the confusion.

You may have noticed that there are 2 choices for each F radio, the F1000 and the F1000 D the D relates to the radios being digital compatible, meaning it can be programmed to be used on current digital systems as well used as a normal two-way radio. Analogue and Digital capable so that it can do both jobs or be ready for when you expand and move to a digital system.

Over the years Icom have been consistent with their accessory connectors, a large range of their radios use the 2 pin connector , the only exception was the small multi connector that they introduced a few years ago. But these new F1000 & F2000 radios have been given their very own connector, very similar to the first generation but will not work with those radios, the new connector includes 2 holding screws. The range of F1000 radio earpieces is huge, with plenty to choose from, you will find any type of radio earpiece for these F1000 and F2000 radios.

If you are looking for a waterproof radio used by many in the marine industry then the F1000 or F2000, depending on your frequency allocation, would be a great choice. It can be dropped to a depth of 1 meter for 30 minutes, so if you worry about splashes on your radio or it sitting in a pool of water on your boat, then you can be assured that it won’t damage this radio. With the latest technology and digital capabilities these are as modern as many counter-parts in the digital two way radio market.

Sepura Releases New SC20 Portable Radios

Sepura are masters of the tetra market, they have produced radios for many years for the emergency services. police and airport security, a forward runner for the digital systems we now see all around the UK. The SC20 is the new generation of Sepura radios ready for the modern day work force. We found this article on this website and thought that our readers would find it useful.

First orders of Sepura's new flagship hand-portable radios, the SC20 series, will be shipped in February.

Shaped by user feedback, SC20 series hand-portable radios are resilient, intelligent and durable, providing intuitive operation and outstanding performance, even in the toughest conditions.

Broadband-ready, the SC2020 (380MHz-430MHz) and the SC2040 (403MHz-470MHz) combine the mission-critical security and advanced performance of TETRA with an optional second high-speed data bearer capability.

A new, powerful Class 3 TETRA engine is paired with a new receiver that surpasses the ETSI specification, a unique combination, extending operational range and stretching coverage into areas where it was not possible before.

The radios' powerful 2W audio capability, enhanced by unique water-porting technology, allows for uncompromised audio clarity, even in continuous heavy rain. Uniquely, the SC20 series boasts IP66, 67 and 68 environmental protection rating, meaning that it is completely dustproof, submersible to a depth of two metres for one hour and impervious to jets of water. Its design also enables it to be easily cleaned by simply rinsing dust and dirt off under the tap.



Additionally, the radios' high-resolution screen, the largest on the market today, is specifically designed to provide a richer user experience. The larger screen enables the display of more comprehensive data, suitable for future applications via high-speed data; it is also viewable in all light conditions, including direct sunlight.

"The SC20 has been designed to deliver the highest levels of robustness, endurance, audio clarity and power. It is designed to place and receive calls where it simply was not possible before," commented Mark Barnby, Sepura's head of product management - devices.

What are the diverse types of a Hytera earpiece

Split by a middle screw, the Hytera PD700 series is capable of connecting all Hytera radios from the same series. This includes the PD715, the PD755, the PD705, the PD785 and the PD795 radios. All of these radios bring something different to the table, in addition to Hyteras trademark solutions. These include an ergonomic design and generally good battery life. The PD715 is probably the most reliable of the bunch. It works really well even in a hazardous environment. It also meets all the ATEX and IEC standards.

The PD755 comes with an increased battery life and a partial keypad, as well as voice call capabilities. Compared to the PD755, the PD705 is a slightly less sophisticated design but it comes with a GPS and supports both analog and digital radios. The PD785 meets all DMR standards and has probably the most ergonomic design out of these models. The PD795 comes with all ETSI and DMR standards.

The Hytera PD500 series connects its radios with a 2 pin connector. The dimensions of the two pins are 3.5mm and 2.5mm. There is a securing screw at the back. This connector can link any combination of the Hytera PD500 series radios together. When I say any, I mean the two radios in that series, since the PD500 series only has two designs, the PD505 and the PD565. The PD505 is very light and somewhat surprisingly, it still has excellent range. Its compact housing results in an improved sound quality. Compared to the PD505, the PD565 has more functions and supports both analogue and digital radios.

PD400 and PD600 series

PD400 and PD600 series radios are connected with a 13 pin connector (which connects to another plastic adapter). This particular connector connects to devices both from the PD400 and PD600 series. The list includes the PD605, PD665, PD685, X1P, X1E, PD405 and the PD415 radios. The PD605 comes with a lightweight design and probably one of the best radios of Hytera when it comes to the prize to value ratio. It has a compact housing and like most of the company’s designs, supports both analogue and digital radios.



The PD665 is another high quality handheld device. It has a lightweight metal casing and a full keypad. The programmable keys and the LCD display are surely welcomed additions as well. The PD685 brings very similar traits to the table, the lightweight design and the full keypad can all be found in the PD665. The X1P is different, it’s a lot thinner and its main advantage that it will work even in very hazardous conditions.

The X1E meets all ETSI and DMR standards and probably the smallest design Hytera has. Those who want an entry level radio for a more than affordable price, will probably have to look at the PD405. This radio can go for about 16 hours in digital mode. The PD415 has an integrated RFID reader and is generally recommended for patrolling personnel. Just like the PD405, it can last up to 16 hours.

The Best Styles of Bluetooth Earpieces

Bluetooth technology has been designed for many different purposes and situations. Consequently, when people want to buy a bluetooth ear piece for a specific situation, there are some things that they will need to consider. Specifically, based on their specific situation and circumstances, they will need to review the best style of bluetooth earpiece that is available on the market today. Since there are different styles that have been made for for one or more reasons, it's important for each individual to do their research to see which style can accommodate their needs. It is also important to note that the kind the person purchases must be comfortable so that they can wear them for an extended period of time and they fit the devices that they will be used for. Listed below are three of the bluetooth styles that’s currently offered by manufactures all over the United States and abroad.

Bluetooth ear pieces for Mobile Phones



Most people take their mobile phones wherever they go. To work, school, church, parties and all kinds of other events that they may attend. Because these phones have become commonplace in many environments, people have a need to handle them and talk to others when their hands are free. This is also a great reason for individuals who work in certain settings to make sure that they are buying the right style that will best fit their needs.

One specific style that some people may choose is the ear cradle style of headphone. In fact, this kind of bluetooth earpiece is idea for people who want to spend their time working out and performing all kinds of other extracurricular activities. People are also encouraged to buy this kind of style because they may be driving when they receive a telephone call from a family member. Or, they may be working at the job typing a memo or walking around taking care of wide hosts of other kinds of activities that are not conducive to holding a mobile phone by hand to the ear. Whatever the situation, this style of bluetooth earpiece technology is great for many different situations and purposes.

Bluetooth ear pieces and Headsets for Music Lovers

In addition to the cradle style for mobile phones, people should also review other styles as well. One specific style that is also functional in many different settings is the DJ over the head headphones. This style has been designed for the serious music lovers, especially those who can appreciate making distinctions in sounds and beats that come from specific musical instruments like the bass, violin, trumpet and other popular instruments. For those who like and prefer this kind, they will also find that this is one of the best styles for keeping out outside noises that normally interfere with a person’s overall entertainment experience. Also, because they are wireless, they are great for people who like to stay mobile during the day instead of remaining in a sedentary position.

Bluetooth Ear Pieces for IPODs

In some situations, people may want to use bluetooth technology with their IPODs. Therefore, they should consider buying an additional popular style bluetooth earpiece technology. This style is known to be very popular, specifically because it is similar to an actual earbud. An ear bud is also another excellent choice for people who want to remain both active and hassle free. Though this is a great choice for people who like to remain mobile in a wide variety of different situations, one of its main draw backs is that they tend to fall out of the individuals ear. Which means, they can also be lost since it lacks additional support to keep them stabilized inside the ear.

ETRI presents a blueprint of the 5G Future

We will see a huge change in the way we access the the internet in the future when 5G is here, at speeds that only big businesses and high level internet companies see at the moment, we will have this to hand on our smart phones and tablets. When 5G is hundreds of times faster than any of the UK's broadbands, households will be looking to the mobile phone companies to supply their home broadband.

A 5G future is no longer a distant one, but an upcoming reality. High quality videos of more than 10Mbps can be served simultaneously to 100 users even in a train running at up to 500km/h. People can experience data rates that are 100 times faster than currently available technologies.

The Electronics and Telecommunications Research Institute (ETRI) of Korea will hold a "5G technology demonstration" on the 18th December, 2015. It will demonstrate future SNS (social network service) and several 5G core technologies such as "millimeter wave", "Mobile Hot-spot Network", "in-band full duplex" and so on.

5G is the next generation wireless technology that would provide even faster data rates, even lower delays, and even more devices connected than 4G. Accordingly, distinct and differentiated applications are expected in 5G.

ETRI's "future SNS" is a kind of trial service model to apply 5G technologies that provides dynamic user-centric connection to neighboring people, things and spaces. It is characterized by instant content-sharing between users, communication with neighboring things, and Giga-bps(Gbps)-grade video applications in vehicles.

5G core technologies demonstrated by ETRI include the following:

-- MHN (Mobile Hot-spot Network) is a mobile backhaul technology that provides high-speed Internet access of Gbps in vehicles at speeds of up to 500 km/h (e.g. KTX in Korea). Almost 100 passengers can watch videos of high quality simultaneously.

-- ZING is a near-field communication technology that enables mass data to be transmitted with 3.5 Gbps data rate between neighboring devices within the radius of 10cm.

-- Single-RF-Chain compact MIMO technology enables a single antenna to simulate the effect of multiple antenna. It can reduce antenna volume and cancel inter-antenna interference in a multi-antenna system.

-- Millimeter wave (mmWave) beam switching technology provides fast switching of radio beams to mobile users, and therefore allows seamless Gbps-grade service in mobile environments.

-- Mobile Edge Platform (MEP) is a mobile edge cloud server on vehicles that enables passengers to enjoy customized Gbps-grade content and connects them with neighbors, things and spaces. It provides user-centric services.

-- In-band Full Duplex technology can transmit and receive signals simultaneously over the same frequency band. It can increase spectral efficiency by up to two times.

-- Small cell SW technology is designed for AP(Access Point)-sized small cell base stations that can reduce communication dead zones and improve data rates per user in a hot-spot area.

"With this demonstration event, we are officially introducing our R&D results on 5G. We will continue to lead the development of 5G technologies. Also, we are trying to develop commercialization technologies needed by businesses, and to construct a 5G ecosystem." said Dr. Hyun Kyu Chung, vice president of ETRI Communication & Internet Lab.

In January, 2016, ETRI will demonstrate Giga internet service and future SNS in a Seoul subway train installed with MHN and ZING kiosks. ETRI will also introduce hand-over technology on a millimeter wave mobile communication system and 5G radio access technology that satisfies 1 millisecond radio latency.
