This was a testament to the collaborative nature of the mobile industry, where giants came together to set a common standard that would benefit consumers worldwide.
112. GSMA’s Adoption and CTIA’s Endorsement
The GSM Association (GSMA), a significant player in the mobile industry, followed suit on February 17, 2009, endorsing the Micro-USB standard. It was a crucial step toward unifying the industry, ensuring that consumers wouldn’t need a different charger for every device. The endorsement was further reinforced on April 22, 2009, when the CTIA – The Wireless Association – also embraced the Universal Charging Solution (UCS). The International Telecommunication Union (ITU) joined the ranks on October 22, 2009, solidifying the power-efficient “one-charger-fits-all” concept for new mobile phones.
113. Efficiency and Sustainability
The UCS, based on the Micro-USB interface, promised not only convenience but also energy efficiency. UCS chargers were designed to carry a 4-star or higher efficiency rating, potentially consuming up to three times less power than unrated chargers. This focus on sustainability added another layer of significance to this technological evolution.
114. The Birth of GSM
In 1987, the mobile telecommunications landscape experienced a monumental shift with the emergence of GSM, which stands for the Global System for Mobile Communications. Initially, it was named after the Groupe Spécial Mobile, the organization responsible for crafting its foundation. However, the name later evolved into its now-recognized acronym. GSM was a pioneering standard that reshaped the industry.
115. Digital Transition and 2G Era
GSM systems marked a departure from analog signals and ushered in the era of digital communication. These systems were often referred to as “second generation” or 2G, representing a turning point in mobile phone technology. They utilized a single radio frequency band, typically at 900 MHz, ensuring that users could access network signals across Europe, regardless of their location.
116. Innovations and Widespread Adoption
GSM networks introduced several groundbreaking features, including the provision for SMS (short message service or texting) and enhanced security protocols. This made them a preferred choice not only in Europe but around the world. Soon, many other countries recognized the advantages of adopting the GSM standard, making it a global phenomenon. Today, an impressive nine out of ten people are within reach of a terrestrial GSM network, underlining its pivotal role in the history of mobile phones.
117. EC-Sponsored MoU
In June 2009, some of the world’s largest mobile phone manufacturers took a significant step towards harmonizing power supply standards. They signed a Memorandum of Understanding (MoU) sponsored by the European Commission, committing to making most data-enabled mobile phones in the European Union compatible with a common External Power Supply (EPS). This agreement aimed to streamline charging methods and enhance user convenience.
EPS Specifications and Global Compatibility
The EU’s common EPS specification (EN 62684:2010) drew inspiration from the USB Battery Charging Specification, aligning with other charging solutions like GSMA/OMTP and those implemented in China. It was a remarkable move towards global compatibility, ensuring that European consumers enjoyed the same ease of charging as users worldwide. In January 2011, the International Electrotechnical Commission (IEC) adopted its version of the common EPS standard as IEC 62684:2011, further solidifying this global shift.
118. Satellite Connectivity
Apart from the conventional mobile phone systems, there exists an entirely distinct approach to global connectivity through satellite-based mobile phones. These devices enable communication in remote areas where wired networks are absent or establishing a conventional mobile network is economically unviable. The concept of satellite mobile phones has revolutionized communication in remote and isolated regions.
119. Inmarsat and Geostationary Orbits
One of the pioneers in satellite mobile communication is the Inmarsat system, developed in 1979 to ensure safety at sea. This system relies on a network of satellites in geostationary orbits, providing coverage across the majority of the Earth. While Inmarsat is the most well-known, several smaller operators also employ geostationary satellites to offer regional satellite phone services.
120. Low Earth Orbit Satellites
An alternative approach utilizes a constellation of low Earth orbit (LEO) satellites positioned much closer to Earth. This concept forms the basis for services like Iridium and Globalstar. LEO satellites offer advantages such as lower latency and the ability to serve areas that geostationary satellites cannot. This diverse approach to satellite mobile phones extends the reach of mobile communication to the farthest corners of the globe.
