The Hazards Of DECT Phones

Why have a conversation about DECT phones when this is a TETRA website? The primary reason is to ensure people don’t mistake the cause of issues and presume TETRA to be at fault. We’ve had to respond to several technical issues that turn out to be caused by DECT phones rather than TETRA.

When the Digital Electronic Cordless Telephones are turned off, the problems stop. If you have one, you may not realize the number of different problems that can crop up. In addition, if your neighbor has a DECT phone it’s possible that the signals from that phone will pulse through your own home. There are no health warnings or even basic guidance for most DECT phones.

Information About DECT Cordless Telephones

The modern digital cordless devices use pulsed microwave radiation. This is no different from the standard mobile phone. As long as the mobile device is plugged in, you can expect an emission level of about 6 V/m.

The base recharge stations emit the waves of radiation whether or not the phone is in use. As long as the base unit of a DECT phone is plugged in, it will emit microwave radiation non-stop. Because of this, many people regard cordless phones as problematic at best.

Recently, a paper was published in Lennart Hardell connecting brain tumors increased in groups who used regular cordless phones over the course of 5 years. Since a DECT phone is mobile, most people leave their base unit in a room where they often work.

Do you have one in your home or office? Try to keep the base unit as far away from where you either sleep or sit. You should also keep any extra handsets away from your sleeping area, as well. Don’t forget, these emissions do go through walls, so you might be sending them towards your neighbor.

DECT technologies aren’t exactly the same as mobile phones, however. These cordless telephones use a fixed power. The pulses of a DECT phone is much stronger and more aggressive than mobile phones, which turn their power levels as low as possible. DECT phones simply don’t do this.

DECT Pulse Frequency Concern

Remember that DECT phones should have warning labels. They could easily be up to 100 times worse than any ordinary mobile device. This is particularly true if it’s used in an area already heavy with emissions. This is due to the pulse frequency.

GSM mobile devices pulse at a rapid 217Hz. DECT pulses are much lower, at 100Hz. The lower the frequency, the more effect it has on humans and other living creatures. If there are any ELF pulses, then watch out. Extremely low-frequency pulses can really wreck your body up. This is why TETRA can be so dangerous.

TETRA pulses are at 17.6Hz. Such a low frequency actually hits the human brainwave rhythm range. When Dr. von Klitzing published his research on DECT phones, he found that samples of blood taken from children who lived near DECT phones showed corpuscles that didn’t grow properly. These children showed signs of aggression and/or listlessness, as well as sleeplessness.

With the removal of the DECT phone, however, these children began to normalize.

Taking Military Technology Into The Everyday World

It’s long been known that communication is vital to a successful military operation. However, there are many challenges to getting it right. You’ll have to consider the case of “a bridge too far” in Arnhem to follow this.

However, it’s not just the military that has had their fair share of struggles with communication. In The King’s Cross Underground there was a fire in 1985 wherein 31 persons died. It may have been far less serious and catastrophic had they had the proper communications in place.

For decades, each new generation of radio systems had tried to overcome the typical issues of having enough bandwidth, enough range and plenty of frequency. The latest improvements were in 1995 and brought TETRA or Terrestrial Trunked Radio with them.

TETRA is digital and as a trunked mobile radio, it was developed by a European Telecommunications Standard Institute or ETSI that set a goal to meet the multiple levels of interoperability that was required in the development of the infrastructure of the radio terminal products.

TETRA was initially designed for the military and first utilized in 1997. Today, there are hundreds of TETRA systems throughout the nation and it’s a major innovation that readily represents over 150 organizations within 35 countries that were involved in the creation, development and the deployment of the TETRA system.

Many armies of many nationalities have utilized the development of such technology. This includes NASA as well as ARPA in the United States of American. The importance of the communication is consistent in all aspects of military operations. It’s also vital to police communication and emergency services as well.

The goal of TETRA was to meet all of the needs and requirements of traditional mobile radio such as public safety, transportation needs, government, military, utilities, public access mobile radio or PAMR, oil industries, gas utilities and commercial industry.

With the advent of digital communication and incompatible protocols, there have many many issues in the interoperability between various pieces of equipment. The standards of TETRA ensure that the air interfaces with the various network interfaces. They ensure that there are plenty of opportunities to interact within the system for all required communications regardless of the manufacturer.

Public safety is by and far the largest of the TETRA market that is working today. It involved both the nationwide networks as well as the operational autonomy and the interoperability with the services that are utilized during an emergency.

Asia is by and large the quickest growing TETRA market today and there’s huge growth in the European sectors as well.

The second largest growth spurt has been seen in the transportation industry. With mass rapid transport sytems and metropolis airports TETRA is on the cutting edge of technology and uses non-tactical operations as an application that is part of the functioning system. It stems from the requirement for constant communication and military as well as emergency services training.

How It All Functions

In order for it to all function and remain operable, there are specific points that TETRA must set as a standard for the industry. Supported by independent manufacturers it will allow the competition to show its sources and show the security and allow a greater selection of terminal products for user applications.

While still remaining competitive, TETRA must ensure that all of the manufacturers are also in collaboration for the benefits of the end user. They must also use the PMR and user organizations as TETRA sets the standard to develop the required needs of the PAMR operations.

Latest Small Business Telecoms Solutions

While cell phone technology has essentially become ubiquitous and an integral part of business communications, the good old fashioned phone line is still a very important technology for pretty much all businesses.

Over the last ten years or so, a lot of high end VoIP technology has become ever more accessible to small business and even for private home use. Large businesses have enjoyed far cheaper and much more reliable phone connections for decades now, so it is about time that smaller and start up business can do the same.

best cordless phoneVoIP essentially uses your Internet connection as the means to transmit voice calls, rather than the plain and simple phone line. This has a lot of benefits, not just the fact that call costs are drastically cheaper. The standard phone line is not a particularly secure form of communication, whereas VoIP can be made very secure with additional technology added in.

With a very basic VoIP box set up and configured, you simple need to add the best cordless phone sets and your business will be ready to communicate with the outside world. These days cordless phones are advanced enough to have allow business user to have all the features of a regular desk phone. Speaker phone, phone books voice mail and call waiting and transfers are all possible.

And the advantage is that you can simply bring the phone with you within range of the office system. If you need to call over to someone’s desk or into a meeting, but at the same time need to be able to take an important call, you can just bring you phone with you.

If phone bills are a major part of your business, then getting set up with modern Internet phone technology can be a great investment. Basic set up for less than 10 phones will be fully up and running for less than $1,000 and many businesses report that the savings on bills pays for that investment in less than one year.
