Laila Ohlgren
Ragnhild Laila Lillemor Ohlgren ( Andersson; 19 November 1937 – 6 January 2014) was a Swedish telecommunications engineer who is seen as the developer of mobile telephony together with Östen Mäkitalo, both engineers at Telia. In particular, she successfully introduced storage of the telephone number to be dialed in the phone's microprocessor so that connection could be achieved by pressing the call button. This avoided transmission breakages caused by obstacles such as trees during more lengthy traditional dialing. The approach was subsequently adopted worldwide. For her efforts, in 2009 she became the first woman to be awarded the Polhem Prize for technical innovation. Early life Born in Tingshammer just outside Stockholm on 17 November 1937, Ragnhild Laila Lillemor Andersson was the daughter of Johan Arvid Andersson and his wife Sally Elisabeth born Carlsson. The family name was subsequently changed to Tingshammar. She was brought up by her single mother in difficult con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telecommunications Engineer
Telecommunications engineering is a subfield of electronics engineering which seeks to design and devise systems of communication at a distance. The work ranges from basic circuit design to strategic mass developments. A telecommunication engineer is responsible for designing and overseeing the installation of telecommunications equipment and facilities, such as complex electronic switching system, and other plain old telephone service facilities, optical fiber cabling, IP network, IP networks, and microwave transmission systems. Telecommunications engineering also overlaps with broadcast engineering. Telecommunication is a diverse field of engineering connected to Electronic engineering, electronic, civil engineering, civil and systems engineering. Ultimately, telecom engineers are responsible for providing high-speed data transmission services. They use a variety of equipment and transport media to design the telecom network infrastructure; the most common media used by wired ...

Skogskyrkogården
(; ) is a cemetery located in the Gamla Enskede district south of central Stockholm, Sweden. It was inaugurated in 1920 and was inscribed on the UNESCO World Heritage List in 1994. Its design, by Gunnar Asplund and Sigurd Lewerentz, reflects the development of architecture from Nordic Classicism to mature functionalism. History Skogskyrkogården came about following an international competition in 1915 for the design of a new cemetery in Enskede in the southern part of Stockholm, Sweden. The entry called "Tallum" by the young architects Gunnar Asplund and Sigurd Lewerentz was selected. After changes made to the design on the recommendations of the competition jury, work began in 1917 on land that had been old gravel quarries that were overgrown with pine trees, and the first phase was completed three years later. The architects' use of the natural landscape created an extraordinary environment of tranquil beauty that had a profound influence on cemetery design throughou ...

Telecommunications Engineers
Telecommunication, often used in its plural form or abbreviated as telecom, is the transmission of information over a distance using electronic means, typically through cables, radio waves, or other communication technologies. These means of transmission may be divided into communication channels for multiplexing, allowing for a single medium to transmit several concurrent Session (computer science), communication sessions. Long-distance technologies invented during the 20th and 21st centuries generally use electric power, and include the electrical telegraph, telegraph, telephone, television, and radio. Early telecommunication networks used metal wires as the medium for transmitting signals. These networks were used for telegraphy and telephony for many decades. In the first decade of the 20th century, a revolution in wireless communication began with breakthroughs including those made in radio communications by Guglielmo Marconi, who won the 1909 Nobel Prize in Physics.
