A Ghanaian fisherman has been sentenced to 12 months in prison for stealing a Mobile Phone. A pretty harsh penalty. What do bank robbers get?

 

Info on Satellite Communications

Thursday, October 30th, 2008

Early missions

The first satellite equipped with on-board radio-transmitter that worked on two frequences, 20.005 and 40.002 MHz was the Soviet Sputnik 1, launched in 1957. The first American satellite to relay communications was Project SCORE in 1958, which used a tape recorder to store and forward voice messages. It was used to send a Christmas greeting to the world from U.S. President Dwight D. Eisenhower. NASA launched an Echo satellite in 1960; the 100-foot aluminized PET film balloon served as a passive reflector for radio communications. Courier 1B, (built by Philco) also launched in 1960, was the world’s first active repeater satellite.

Telstar was the first active, direct relay communications satellite. Belonging to AT&T as part of a multi-national agreement between AT&T, Bell Telephone Laboratories, NASA, the British General Post Office, and the French National PTT (Post Office) to develop satellite communication, it was launched by NASA from Cape Canaveral on July 10, 1962, the first privately sponsored space launch. Telstar was placed in an elliptical orbit (completed once every 2 hours and 37 minutes), rotating at a 45° angle above the equator.

An immediate antecedent of the geostationary satellites was HughesSyncom 2, launched on July 26, 1963. Syncom 2 revolved around the earth once per day at constant speed, but because it still had north-south motion, special equipment was needed to track it.

Geostationary orbits

 

Geostationary orbit

A satellite in a geostationary orbit appears to be in a fixed position to an earth-based observer. A geostationary satellite revolves around the earth at a constant speed once per day over the equator.

The geostationary orbit is useful for communications applications because ground based antennas, which must be directed toward the satellite, can operate effectively without the need for expensive equipment to track the satellite’s motion. Especially for applications that require a large number of ground antennas (such as direct TV distribution), the savings in ground equipment can more than justify the extra cost and onboard complexity of lifting a satellite into the relatively high geostationary orbit.

The concept of the geostationary communications satellite was first proposed by Arthur C. Clarke, building on work by Konstantin Tsiolkovsky and on the 1929 work by Herman Potočnik (writing as Herman Noordung) Das Problem der Befahrung des Weltraums - der Raketen-motor. In October 1945 Clarke published an article titled “Extra-terrestrial Relays” in the British magazine Wireless World. The article described the fundamentals behind the deployment of artificial satellites in geostationary orbits for the purpose of relaying radio signals. Thus Arthur C. Clarke is often quoted as being the inventor of the communications satellite.

The first truly geostationary satellite launched in orbit was the Syncom 3, launched on August 19, 1964. It was placed in orbit at 180° east longitude, over the International Date Line. It was used that same year to relay experimental television coverage on the 1964 Summer Olympics in Tokyo, Japan to the United States, the first television transmission sent over the Pacific Ocean.

Shortly after Syncom 3, Intelsat I, aka Early Bird, was launched on April 6, 1965 and placed in orbit at 28° west longitude. It was the first geostationary satellite for telecommunications over the Atlantic Ocean.

On November 9, 1972, North America’s first geostationary satellite serving the continent, Anik A1, was launched by Telesat Canada, with the United States following suit with the launch of Westar 1 by Western Union on April 13, 1974.

On December 19, 1974, the first geostationary communications satellite in the world to be three-axis stabilized was launched: the Franco-German Symphonie.

After the launchings of Telstar, Syncom 3, Early Bird, Anik A1, and Westar 1, RCA Americom (later GE Americom, now SES Americom) launched Satcom 1 in 1975. It was Satcom 1 that was instrumental in helping early cable TV channels such as WTBS (now TBS Superstation), HBO, CBN (now ABC Family), and The Weather Channel become successful, because these channels distributed their programming to all of the local cable TV headends using the satellite. Additionally, it was the first satellite used by broadcast television networks in the United States, like ABC, NBC, and CBS, to distribute their programming their local affiliate stations. Satcom 1 was so widely used because it had twice the communications capacity of the competing Westar 1 in America (24 transponders as opposed to the 12 of Westar 1), resulting in lower transponder-usage costs. Satellites in later decades tended to have even higher transponder numbers.

By 2000 Hughes Space and Communications (now Boeing Satellite Development Center) had built nearly 40 percent of the satellites in service worldwide. Other major satellite manufacturers include Space Systems/Loral, Lockheed Martin (owns former RCA Astro Electronics/GE Astro Space business), Northrop Grumman, Alcatel Space, now Thales Alenia Space, with the Spacebus series, and EADS Astrium.

Termination fees

Tuesday, October 28th, 2008

Some of Europe’s smaller mobile companies have urged the European Commission not to dilute or delay moves to cut the fees operators charge each other. The Commission wants to cut termination fees by up to 70 per cent by 2011. Big operators, for which termination rates account for up to a fifth of revenue, say the reduction is too steep.

Nokia news

Tuesday, October 28th, 2008

Nokia Siemens Networks have won a deal to provide core network technology for Japanese NTT DoCoMo’s next generation mobile network together with Fujitsu.

Nokia Siemens, together with Panasonic Mobile Communications, is also providing radio technology for NTT DoCoMo’s Long-Term Evolution (LTE) network.

G’day - I’m on the plane

Friday, October 24th, 2008

Qantas has become the first airline to trial using mobile phones during a flight. The trial will run for three months on a Boeing 767 (registration: VH-OGI). During the trial, passengers will be allowed to send and receive text messages and emails, but will not be able to make or receive calls. If the trial is successful, Qantas may become the first airline to allow passengers to use mobile phones in flight, possibly including voice calls.

Using a Mobile In Japan

Wednesday, October 22nd, 2008

Talking on a mobile phone while riding a bus or train is frowned upon, and messages asking passengers not to make calls and to switch their phones to silent mode (”public mode” or “manners mode” in Japanese) are played frequently. This, combined with the low per-message price, ample allowed length per message (10,000 characters per message) the ability to enhance messages with special characters, emoticons, pictures, and small animations, and to write in English or Japanese, has made e-mailing from cell phones extremely popular among people of all ages.

Many people send and receive a large number of e-mails daily; teenagers are especially fond of this simple, fast, and private method of communication, though many schools ban the use of cellular phones on campus.

E-mails are also a popular way to communicate with potential friends or lovers. Many internet sites maintain phone-accessible portals via which users can search for and contact others with similar interests.

Japanese mobile phones have the capability to use very large sets of characters and icons based on JIS standards that define characters for industrial appliances. More than one thousand characters including all of the Latin alphabet, hiragana, katakana, kanji and special characters like cm (centimeter), arrows, musical notes and more can be used to compose messages. Japanese mobile phones also use emoticons differently from Western mobile phones.

These character sets are used extensively, and often in a way that do not use their original meaning by relying more on the information based on the shape each character has. For example, ‘\’ may be attached at the end of a sentence to show that they are not happy about the event described. A sentence like “I have a test today\” (translated) might mean that he or she didn’t study enough, or that the test itself is depressing. Some of these usages disappeared as suitable icons were made but these newly made icons also acquired a usage not originally intended. Another example deals with the astrological symbol for Libra. It resembles a cooked and puffed mochi, and is sometimes used in a happy new year’s message as mochi are often eaten then. The symbol for Aquarius resembles waves, so this would be used to mean ’sea’. The number of icons gradually increased and they are now colored on most cell phones, to make them more distinct. ASCII art is also used widely and many of them are faces with expression.

Interesting stuff on Media Markt the German electronics retailer

Monday, October 20th, 2008

Media Markt is a German chain of stores selling consumer electronics with numerous branches throughout Europe. It is Europe’s largest retailer of consumer electronics.

Media Markt was founded by entrepreneurs Leopold Stiefel, Walter Gunz, Erich Kellerhals, and Helga Kellerhals. The first store opened on 29 November 1979 in Munich.

Today, it is owned by MediaSaturn Holding, which also owns the rival Saturn chain of electronics and media stores. MediaSaturnHolding in turn is owned by the German retail company METRO AG.

MediaMarkt is active in Greece.

Media Markt is known in Germany for its humorous, but sometimes crude, advertising campaigns; for example, the slogan “Lasst euch nicht verarschen” (”Don’t let them make an ass of you”).

Media Markt’s main slogan “Ich bin doch nicht blöd” (I am not stupid) has been translated into the languages of the other countries where the company operates.

2006 World Cup advertising campaign

Prior to the 2006 World Cup, Media Markt launched a campaign, claiming to be the “best fan supplier” (”Bester Fanausrüster“), with commercials showing international football fans shopping at Media Markt, showing exaggerated stereotypes of the participating countries, and making fun of the Austrian team, which did not qualify. This included a French seductress, Dutch fans smoking marijuana in caravans, or a Saudi haggling - to pay more. Germans fans were portrayed with big bellies, asking for refrigerators to keep their beer cool, rather than looking for a new TV set.

An additional series of ads, promoting a rebate of €10 for each goals Germany scores (except penalty shoot-outs), showed international soccer fans begging the Germans to score as many goals as possible - against their own team.

When the Netherlands lost to Portugal, Media Markt used a quote from a 1970s show featuring the late Rudi Carrell, a Dutchman who was a long-time TV celebrity in Germany, to express Schadenfreude. A World Cup trophy is shown to grieving Dutch fans in their caravan with the comment “This would have been your prize!”.

Polish advertising controversy

In March 2006, the “Poland version” showed moustache-wearing Polish customers praising the shop for “prices deep like Polish soul” before hugging the German sales managers, who looked quite uncomfortable in the bear hugs. Afterwards, one of the Germans pointed out that his watch was still there, and that “The Pole is an honest person, after all”. Then, the three men are shown to be missing their trousers.

This commercial caused a scandal in Poland, for the widely known German stereotype of Poles being thieves. Media Markt argued that the advertisements also made fun of other national clichés, including Germans, and none of the other clichés were perceived as negative towards the people they presented. Its aim was to exaggerate the cliché of the Polish thief to dismiss it as unjustified prejudice, Media Markt claimed.

The store apologised and withdrew the advert after their Polish branch asked to do so, following protests in Poland, a call from the Polish embassy in Berlin and protests from German Polonia.

Portuguese advertising controversy

In January 2008 Media Markt launched a campaign presenting a fictitious country called “Dumb Land”, where several characters were presented as being from this country, which even has an anthem. A central theme of this campaign presented a Boy Scout as an idiot. This really upset people as many consider Scouts to be responsible and valued members of society. An online petition was created to persuade Media Markt to withdraw the campaign and to offer a public apology. Due to this petition and a lot of pressure from the Scouting movement, Media Markt had to remove the Boy Scout from their campaign, including TV and radio ads.

Did you know about Digicel?

Wednesday, October 15th, 2008

Digicel is a mobile phone network provider in the Caribbean region. Based in Jamaica, the company provides mobile services in 23 countries and territories in the Caribbean and Central America with more than six million wireless users. Digicel is preparing to launch in the British Virgin Islands, Honduras and Panama which will bring it to a total of 26 markets. Meanwhile its sister operation Digicel Pacific to date (Jan 2008) operates in four markets in the South Pacific (Samoa, Papua New Guinea, Tonga and Vanuatu) with launch imminent in Fiji. The company’s largest competitor in the Caribbean region is Cable & Wireless’s bmobile brand

 

History

Digicel, first established April, 2001 in Jamaica grew to 100,000 customers in approximately 100 days. In the 7 years since the initial launch, Digicel’s Jamaican customer base has grown to 1.9 million users (March 2008). In Haiti, where they launched operations in May 2006, the company reached 1.4 million subscribers by May 2007 and now has more than two million customers making Haiti Digicel’s largest customer base to date. Digicel is 100% owned by Irish entrepreneur Denis O’Brien. The company has a marketshare of roughly 70% in Jamaica.(Digicel makes cellphone connection in Jamaica)

Competitive Issues with Incumbents

The majority of Digicel networks start up in countries where the telecommunications market has been newly liberalised. As a result there have been numerous rows between Digicel executives and former state incumbent operators over interconnect agreements. This has led to Digicel taking some incumbent operators to court.

Digicel Expansion

In 2006 Digicel expanded into the South American mainland as well as the Pacific. On September 2006 Digicel acquired an unrelated mobile phone provider Digicel Holdings in El Salvador, rebranding it as El Nuevo Digicel, and a mobile telecommunications license in Guatemala. Then in December 2007 Digicel won a highly competitive bid for a mobile license in Honduras and expects to launch in its second Central American country in 2008. Digicel in Guatemala must be launched before June 18th (2008), when its authorization expires.

 

In 2007 Digicel also expanded their presence in South America and in the country of Guyana, acquiring U*Mobile, now rebranded as Digicel Guyana Ltd as well as launching in Suriname (December 2007) and French Guiana (June 2006). Digicel now operates in 23 markets. Digicel won a licence to operate in Panama in May 2008.

Digicel Pacific

Digicel’s sister operation in the Pacific Islands region currently operates in Samoa and in Papua New Guinea, Vanuatu , Tonga, Fiji, as well as an experimental licence in the Solomon Islands.

Partnership with ezetop

On 20th March 2007, Digicel signed an agreement with ezetop to provide mobile credit to the diaspora across the world. ezetop currently markets Digicel top-up for Anguilla, Antigua and Barbuda, Dominica, Grenada, St. Kitts and Nevis, St. Lucia, St. Vincent and the Grenadines, Barbados, Jamaica, Trinidad and Tobago, Haiti, Guyana and Samoa in retail stores in the US, the UK and online around the world at their website.

 

Partnership with Vodafone

On 6 February 2007, Digicel signed a three-year partnership agreement with Vodafone. Though both will remain separate and independent companies, the agreement, which includes Digicel’s sister operation in Samoa, will result in the offering of new roaming capabilities. The two groups will also become preferred roaming partners of each other.

Digicel Foundation

Digicel and its shareholders set up a foundation that has been actively involved in charitable work throughout the Caribbean involving a wide range of school and sports projects as well as providing assistance after Hurricane Ivan devastated many of the islands, especially Grenada and the Cayman Islands. To date the Digicel Foundation in Jamaica has allocated US$7 million to sustainable development community projects in the country. In Haiti the Digicel Foundation built 20 primary schools in its first year.

Digicel are the official sponsors of the West Indian cricket team.
