What is GSM? Global system for mobile communications. I quickly learned that with all the trips I take to Asia and Europe having a phone with GSM was critical. GSM means Global System for Mobile Communications and is a digital two way radio format used widely in Europe and Asia. In the U.S. only T-Mobile and some AT& T and Cingular phones use GSM. It keeps calls separate by assigning a slice of time to each carrier.





Dial a number of taxi service. These are call-in services. Tell them the address from where you want to be picked and the place to be dropped. The dispatcher connects to the special digital communication of the taxi company and finds a taxi that is the closest to your address. The taxi reaches you in 5-10 minutes. It is far more convenient. You can book a taxi service without leaving the comfort of your home.


The DIGITAL 2 WAY RADIO is a crucial part to the flying experience. You don't want to skimp here. Get yourself the nicest DIGITAL 2 WAY RADIO you can afford. The digital 2 way radio should be listed on the box of the helicopter or listed in the recommended parts on websites when purchasing the copter. The more channels the radio has the better. But buy a good popular brand name DIGITAL 2 WAY RADIO, that way if you end up with questions about it the instructor or experienced pilot can help you.


Other features - They include infrared remote control, digital TV tuner, teletext, contrast auto tracking system, 3D digital comb filter and digital electronic programming guide. There may be a provision to connect the TV to a PC in order to access the pictures and videos stored on the PC. Interestingly as in a PC there is a provision for child lock or parent control wherein certain objectionable channels may be blocked. Some TVs have ambient light sensor and a noise reduction circuit. There are of course the headphones with a socket connection for blocking out the sound for the other viewers who do not wish to be disturbed by the audio. There is any number of channels to be viewed from BBC three, BBC four, BBC News 24, Sky News and even DIGITAL RADIO channels.


Whereas two-way radios usually fall in the frequency range of 150MHz to 900MHz; these frequencies travel in straight lines. Radio waves can be reflected, or bounce off surfaces so the straight line between radios, may not always be so straight. Anyway as a general rule these waves cannot travel over the horizon or behind solid obstacles. Because of this reason, you have to factor in antenna height as well for sending signals farther.


This phone makes up to the perfect choice available from amongst the different Mobile Phones in the market. There are some amazing deals also available on the online platform for you to choose the best one amongst them and get the phones at the best prices.

Doctors have discovered that an important knee ligament, first described in an 1879 paper, before being subsequently ignored for well over a century, is actually a very real and important body part.


Anterior cruciate ligament (ACL) tears are a common problem for many athletes. They are notoriously difficult to repair and the recovery is a tough and painful process that can take up to a year. Following treatment, however, many patients still complain of aches and pains and it is not at all uncommon for the joints to fail the necessary pivot-shift tests (performed so the doctors can check the success of their surgeries). Repeat injuries are also inexplicably common.


Last month, it was announced that a team of Flemish doctors appears to have finally solved this persistently vexing riddle and, in so doing, they validated a discovery made over a century ago.


Paul Segond, a 19th century French surgeon who is known for greatly aiding the development of Obstetrics and Gynaecology (as well as describing the Segond fracture), wrote of the ligament as a “pearly, fibrous band” in 1879. Segond posited that it was an additional ligament, but anatomists did not consider the initial discovery to be accurate.


After reading Segond’s paper and deciding that there may be something to it after all, the team of knee surgeons and an anatomist began investigating the possibility that Segond’s mystery ligament was, in fact, a very real part of the Human body.


The team examined the knees of 41 cadavers, finding that 40 of them actually contained Segond’s ligament, just as he’d described it a hundred years earlier.


With this (re)discovery now published and proven, the ligament has been named as the anterolateral ligament (ALL).


The anterolateral ligament joins the other jointhere most important by doctors and anatomists, such as the lateral femoral epicondyle (LFE), lateral collateral ligament (LCL), Gerdy’s tubercle (GT), popliteus tendon (PT), popliteofibular ligament (PFL), and, of course, the aforementioned anterior cruciate ligament (ACL).


Surgeons are already considering ways in which to repair ALL tears and damage, with the hopes of improving the quality of life for anyone who suffers any ligament damage to the knees. This rediscovery is likely to become a very significant one in the field of sports and athletics, across both amateur and professional playing fields.

So, you want to know whether you should get the aPad or Apple's iPad. When it comes to features and functions, the aPad and the iPad are essentially the same. The iPad is a well-loved product with a lot of hype surrounding it. The only drawback is its hefty price range, which might be out of many people's budgets. Meanwhile, cheap android tablets are flooding the market and many people are choosing them instead of the iPad. And why not, especial when both have so many similar features and apps?


In contrast, Android 4.0 has more improvement than the previous version. We not only see the redesigned interface and many upgrades in details, but also we notice the integration of Android mobile phone and nexus 9 in the brand new Android 4.0. Of course, you can understand this as the integration of Android and this is a good news for developers and hardware producers. However, in today's mobile phone area, all the customers care about the apps more than hardware, a well-developed platform can attract more app developers. This will brings more business to them.


Over the years, food providers (restaurants and grocery stores) have developed a trend of competing with each other, in part, by increasing the serving sizes of food products. As a result, the consuming public has come to expect larger sizes and to see them as "normal". We are attracted to signs in front of the restaurants which advertise "the world's largest pancakes" and "free triple dips of ice cream with the purchase of the 14 ounce steak". While these offers may be appealing, they are killing us.


Toshibas teasing us with a video for its new, unnamed android tablet for restaurants: we can see twin cameras, HDMI, mini USB and normal USB, an SD card slot and a swappable battery. So itll probably weigh a ton. Heres hoping it doesnt suffer from the problems that plagued its predecessor, the Folio 100.


Additionally Barnes and Noble cut the prices of its restaurants first edition NOOK Wi-Fi and G Wi-Fi devices to and respectively. The price of the NOOK Color, a 7-inch, Wi-Fi-only Android tablet, will remain the same.

Ham radio (so called because its operators were originally derided as being ‘hammy’ in the 19th century, when the technology first emerged) is a term that applies to any form of amateur radio broadcasting.




There are designated radio frequency spectra available solely for public use. Uses range from recreation to communication and the non-commercial exchange of ideas. ‘Hams’ take advantage of these frequencies in order to transmit any number of things


Strictly speaking, there should not be any money involved in amateur radio (hence the term ‘amateur’). Although the majority of Ham radio practitioners are actually extremely knowledgeable about radio technology (don’t let the ‘ham’ part fool you), they are not considered professionals because they do not profit from their endeavours. Conversely, commercial broadcasting involves (a lot of) money: royalties are paid, producers and performers are paid and the whole thing is ultimately a commercial exercise.


Hams use a large amount of frequency bands from all across the radio spectrum, but the majority of frequencies are to be found just above the AM band.


A lot of hams, however, use VHF FM, operating hand-held transceivers that send on one frequency and receive on another. Local radio clubs set up FM Repeaters (which borrow space from other broadcast devices such as towers and, in doing so, amplify the radio signal’s strength hundreds of times over), so that hams can communicate with each other wirelessly over a distance of hundreds of miles.


As an example of what hams get up to, here’s an excerpt from Gary Brown, of How Stuff Works.com


“Although a ham radio does broadcast in all directions, hams generally do not use their radios in a broadcast kind of way as a disk jockey would at a radio station. In normal AM or FM radio, one disk jockey transmits and thousands of people listen. Hams, on the other hand, conduct two-way conversations, often with another ham or with a group of hams in an informal roundtable. The roundtable of hams may be in the same town, county, state, country or continent or may consist of a mix of countries, depending on the frequency and the time of the day. Hams also participate in networks, often called nets, at predetermined times and frequencies to exchange third-party messages. In the case of disasters, hams exchange health and welfare information with other hams”.


To become a ham, I recommend that you join a club. You’ll need an amateur radio license, of course, but this won’t break the bank, I’m sure.


I hope that helps, Melissa.
