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.

World's first truly wireless headphones unveiled

The world’s first “true wireless” in-ear headphones have been unveiled at the IFA technology show in Berlin, by Japanese consumer electronics manufacturer Onkyo.

Most in-ear headphones that are advertised as “wireless” actually have a cable connecting the two earpieces. They are known as wireless because they do not require a cable to connect to a media player or a smartphone.

The W800BT headphones, developed in partnership with audio group Gibson Innovations, consist of two earbuds that work independently from each other and deliver a balanced sound across a frequency range of 20Hz-20kHz. They connect to each other and to a smartphone wirelessly, using Bluetooth.

Onkyo claims that the headphones offer a clear and accurate audio experience with passive noise isolation. The right earpiece also includes a microphone to enable hands-free calls and can be used with any Bluetooth-enabled device.

They come with a charging case for storing the headphones with its own internal battery, providing up to 15 hours of talk time and 12 hours of music reproduction.

“The W800BT allows you to immerse yourself in audio in a free and natural way,” said Sebastiaan Gruijters, Onkyo Business Leaders at Gibson Innovations. “We’re proud to showcase this genuine breakthrough innovation here at the IFA in Berlin.”

The W800BT in-ear headphones are priced at €299.99 (about £220) and will be available in Europe from November 2015.

Onkyo also unveiled a pair of high-resolution on-ear headphones at IFA, in partnership with Gibson, as well as a new range of portable high-resolution audio speakers.

Gibson has been an investor in Onkyo since January 2012, when it acquired a majority share of Onkyo USA.

“We strive to achieve an optimum balance between the ideal acoustic design and a deep understanding of how we, as humans, interact with technology,” said Matthew Dore, sound and acoustics engineering lead for Onkyo products at Gibson Innovations.

P.S - This Message Will Self Destruct: New Email App Allows Automatic Encryption

Remember how Inspector Gadget always got given those top-secret messages that would self-destruct upon reading? Well, a new app has been devised that can do just that for your emails.

Confidential CC is a free app, designed for both Android and iOS devices, that allows the user to send self-deleting, automatically encrypting files that can be viewed only once...And never again.



The app also prevents recipients from forwarding or printing the messages in question. In a very real sense, you can read it once and then its gone.

“You receive all your email like usual, we just add a new address line that lets you send a CCC self-destruct email,” said the app’s Co-Founder Warren Barthes, formerly an executive with French Telecom, at the Collision Technology Conference in Las Vegas, Nevada earlier in the year.

Of course, other secure email apps have been attempted before, but none has proven to be 100% safe. Could Confidential CC be the one that finally achieves it?

The app was created by co-founders Warren Barthes, Rachel Triggs and Jeremy Landau and their story (according to the group’s official website, anyway) goes something like this:

“Confidential CC was born when the co-founders realized they had a common need - to send an email without a trace. A short time later they set out for this goal. After working hard to confirm the technology, legal and execution were possible, the CCC team took their idea to the next level by striving to provide not only confidential email, but an updated, smart, and attractive user interface across all systems, catered to our users’ daily lives”.

Compatible with Yahoo!, AOL, Gmail, Hotmail and Outlook, amongst others, the app allows users to access all their email accounts from one place and has been designed to be as user friendly as possible. Confidential CC can also cancel accidentally sent messages and can be instructed to send email messages out at a specific time of day.

It looks good, but the customer reviews have been a mixed bag so far.

iTunes user Alukakum praised the usability and the continuing updates, but a customer named IT User Review panned it, calling the app “clunky at best” and pointing out that users can only synch one email account per provider to the app itself.

Of course, this app is new to the marketplace, so customer reviews are few and far between.

Nevertheless, it goes without saying that, if Confidential CC can deliver on its many promises, then it could become a very profitable enterprise indeed. Co-Founder Rachel Triggs certainly thinks so.

“It’s unacceptable that email, which is free and open for all, is presenting such huge risk to users. Maybe, in five years, people will use CCC lines in Gmail, Outlook, everywhere.” She said at the Collision Conference.



If all goes according to their plans, this could be the first chapter in the story of how a small start-up firm from the US revolutionized email security for all online customers. As with all things, time will tell.

Have Scientists Located The Actual Holy Grail Of The Cancer Cure

Cancer affects millions of lives, possibly even more. Everybody knows somebody that has been forever hurt, either physically or emotionally, by this vicious, unforgiving ailment. Most of us know somebody who has lost their life to the disease.

Despite this, cancer survival rates are higher than ever before. In recent years, cancer treatment has improved rapidly, but a complete cure has always appeared to be just beyond reach, a tantalising Holy Grail of medical science. This month, however, an announcement was made that could have the potential to end all that.

The good news is that human trials could begin in as little as four years’ time. If those trials prove to be successful, then science will have made a major stride towards eradicating the disease completely.

A joint Dutch/Canadian team stumbled across this miraculous discovery whilst searching for ways to treat malaria in pregnant women.

According to the team, the carbohydrate that malaria attacks in the placenta is exactly the same as a carbohydrate present in cancer cells.



As Metro.co.uk reports, Ali Salanti from the University of Copenhagen said, “for decades, scientists have been searching for similarities between the growth of a placenta and a tumor (...) The placenta is an organ, which within a few months grows from only few cells into an organ weighing approx. two pounds, and it provides the embryo with oxygen and nourishment in a relatively foreign environment. (...) In a manner of speaking, tumors do much the same, they grow aggressively in a relatively foreign environment.”

Intrigued by this idea, the team tailored a special malaria protein to include a toxin designed to target cancerous cells. The cancer cells absorb the protein and are then in turn killed by the malaria virus. Theoretically, this idea is sound and experiments on mice with cancer have already begun.

It’s definitely early days yet, but the team are hopeful that this innovative new treatment could provide scientists with a valuable weapon in the fight against cancer. If the trials are successful, the potential benefits are simply staggering to consider. It just goes to show that no dream is too big to accomplish, provided we never stop believing that it’s possible. Imagine a world without cancer and perhaps, in time, we won’t have to.

Motorola Solutions provides secure and efficient communications for Milan airports

Motorola really are the leader in complex communication systems, time and time again we see (and report) stories of Motorola completing projects for prestigious businesses and organisations. This article highlights their latest finished project.

Airport operator SEA Group (Società Esercizi Aeroportuali S.p.A.) has selected Motorola Solutions to improve operations and ensure the highest levels of security, efficiency and effectiveness at Milan’s Linate and Malpensa airports. Deploying a TETRA Dimetra IP Compact radio communications system to connect both of Milan’s airports, SEA is able to provide enhanced customer services with rapid flight turnaround and more efficient terminal operations.

"With 1,200 operating radios and an increase in operations, SEA needed a more dynamic solution for communications," says Fabio Degli Esposti, information & communication technology director, SEA. "Faced with the need to replace an outdated system and the need to cope with an increasing demand of services, the only choice for us was to switch to digital technology, which is able to guarantee a safe and effective service."



In Malpensa - where the old and the new systems had to coexist in the migration phase - everything was fully operational within just two weeks, including the configuration of 1,000 new radios. At Linate airport, the system, supporting 400 new radios, was set up in just a week.

“SEA could not afford any inefficiency," says Giuliano Posenato, customer service manager, Motorola Solutions Italy. "The implementation had to be very fast, because the requirement was to change the engine on the machine while it was still running.”

Motorola Solutions’ high-performance TETRA base stations now deliver TETRA network coverage in both airports. Old radios used by personnel throughout the airports where also replaced with new TETRA digital handsets.

Motorola Solutions has signed a four-year managed services agreement with SEA, guaranteeing technology evolution including the replacement of its complete telecommunication system (controller, base stations and radios). Motorola Solutions will provide global integrated services infrastructure with highly qualified technical support and certified repair centres that will provide fast repair times and expert technical support for the system for many years to come.

In September 2015, Motorola Solutions will upgrade the connections at both airports with the latest generation of Motorola Solutions TETRA system Dimetra 8.2 enhancing data transmission and offering the SEA the opportunity to develop rich data services to further improve both operations and the customer experience at Milan’s airports.
