Han gör det mobila bredbandet bredare

NYHET

Publicerad 2013-01-09
Rapporterna duggar tätt: Svenska mobiloperatörer har kapacitetsbrist i näten. Mobilsurfandet har bara i år ökat med drygt 150 procent hos exempelvis Telia och Telenor enligt företagen själva. Möt KTH-forskaren som jobbar på en lösning på problemet.

De hastigheter som utlovas reklamkampanjerna för mobila bredband är fiktion och fantasi. För att erhålla topphastigheten - låt anta 10 Mbit/s - skulle du behöva vara ensam användare på mobilmasten. Samma sak gäller för en åtkomstpunkt i det trådlösa nätverket hemma, på flygplatsen eller på jobbet. Det säger Alexandre Proutiere, universitetslektor och forskare vid KTH.
Han forskar bland annat om hur hastigheten i Wifi-nätverket ska kunna skruvas upp till utlovad dito. Men han jobbar också med att se till att de mobila bredbanden lever upp till bredbandsleverantörernas löften. Till sin hjälp har han fått dela en rejäl forskningspeng från EU, ett så kallat ERC Starting Grant.
Lösningen enligt Alexandre Proutiere kallas DSA, en förkortning för Dynamic Spectrum Access. En rykande het trend inom alla typer av trådlöskommunikation just nu.
– DSA-tekniken gör det möjligt för enheter som mobiltelefoner, surfplattor och framtidens trådlösa kameror att bli "frequency agile". Det vill säga lättrörliga när det gäller val av frekvensområde att sända och ta emot data inom. Det här öppnar upp möjligheter för till exempel mobiltelefoner att automatisk röra sig inom olika frekvensområden, och kan liknas vid en bil i rusningstrafik som kan välja den fil där trafiken flyter snabbast, säger Alexandre Proutiere.
Vad vill då Alexandre Proutiere uppnå? Jo, 10 gånger förbättrad trådlös kommunikation. Och det i system som vi kommer att använda så väl om tio år som längre fram i tiden.
– För att använda liknelsen med motorvägar och många filer så avser forskningen att se till att betydligt fler uppkopplingar kan äga rum samtidigt, det vill säga en motorväg mer fler filer. Om en motorväg hade 20 filer i en riktning så skulle alla trafikanter kunna köra lika snabbt som hastighetsbegränsningen, istället för att krypköra i bilköer, säger Alexandre Proutiere.
Han tillägger att anledningen till att hans forskning finanserats av Europeiska forskningsrådet (ERC) är för att resultatet har stor potential att påverka samhället på ett positivt sätt.
– Men forskningen har också potential att öka förståelsen för problem inom områden som artificiell intelligens och industrirobotar, säger Alexandre Proutiere.
Forskningsanslaget ger honom möjlighet att anställa fyra forskare som kan bistå honom i hans arbete att utforska möjligheterna med DSA-tekniken.
– Det här har stor potential att bli ett av de främsta forskningsprojekten inom DSA-tekniken i Europa. Faktum är att jag redan gjort en del framsteg, det förflyter ju en viss tid mellan att ansökan skickas in och att man eventuellt beviljas forskningspengar. I detta fall drygt ett år, säger Alexandre Proutiere.
Alexandre Proutiere har en bakgrund som industriforskare bland annat åt France Telecom R&D och Microsoft Research.

Ett misstag som kostat -50%?

Var att gå in i Poseidon i IPS-depån på ca 3.30 CAD. Just nu i ca 1.68 CAD enligt Nordnet.

Yahoo Finance säger 3.22 CAD. Det verkar dock stämma med -50% idag.

Dubbelt så bra köpläge nu som förut?

Bolaget vidtar i alla fall självbevarande åtgärd med att strypa den höga utdelningen.

Sprott fortsätter promota Silver

Why are (Smart) Investors Buying 50 Times More Physical Silver than Gold?

By: Eric Sprott

As long-time students of precious metals investing, there are certain things we understand. One is that, historically, the availability ratio of silver to gold has had a direct influence on the price of the metals. The current availability ratio of physical silver to gold for investment purposes is approximately 3:1. So, why is it that investors are allocating their dollars to silver at a much higher ratio? What is it that these “smart” investors understand? Let’s have a look at the numbers and see if it’s time for investors to do as a wise man once said and “follow the money.”
Average annual gold mine production is approximately 80 million ounces, which together with an estimated average 50 million ounces of annual recycled gold, totals around 130 million ounces available per year. In comparison, annual mined silver production has averaged around 750 million ounces, while recycled silver is estimated at 250 million ounces per year, which adds up to approximately 1 billion ounces. Using this data, there is roughly 8 times more silver available to buy than there is gold. However, not all gold and silver is available for investment purposes due to their use in industrial applications. It is estimated that for investment purposes (jewelry, bars and coins), the annual availability of gold is roughly 120 million ounces, and of silver it is 350 million ounces. Therefore, the ratio of physical silver availability to gold availability is 350/120, or ~3:1.1
Now, let’s examine how investors are allocating their investments between gold and silver. The data below is from the US Mint showing gold and silver sales in ounces:

China’s Major Role in Silver Explained - Silver Investing News

China’s Major Role in Silver Explained
Tuesday December 18, 2012, 4:15am PST
By Michelle Smith - Exclusive to Silver Investing News



The structure of the silver industry in China is almost unrecognizable from the situation 20 years ago, a new report from Thomson Reuters GFMS states. In 1990, China was a relatively small player in silver. Now, the nation is responsible for 17 percent of global demand and produces 14 percent of the world’s silver. GFMS’ latest research reveals that China’s expanding role in the silver market has been driven by the liberalization of its silver industry and over a decade of economic growth.

After the revolution in 1949, gold and silver mining did not feature in the People’s Republic’s economic planning, GFMS explains. Investment in the industry was limited and private trading and personal ownership of the metals was forbidden.
China’s low level of silver production in the early 1980s raised concerns among State Council members, who decided that local production needed to expand in order to support industrialization and move the country toward self-sufficiency.

In 1983, regulations that covered the various aspects of the silver and gold industries, from production to export, were rolled out. The People’s Bank of China (PBOC) was granted monopolistic authority to set prices and buy and sell silver.

That initiated the rise of China’s silver production, which resulted in China becoming a surplus producer by the end of the 1980s. Production surpluses continued in the 1990s, and by 1997, the PBOC realized state stocks were more than sufficient for China’s fabrication needs.

Authorities eventually came to see silver as a metal with which to test deregulation. Exploratory sales from state stocks began in 1998. In 2000, an official trading platform was designated and China’s monopoly on silver ended.

China’s silver supply

China is now the third-largest producer of silver after Peru and Mexico.

GFMS estimates that from 1998 to 2006, government stock sales totaled almost 350 million ounces (m/oz), more than 4 percent of global silver supply during that period. However, the firm confidently assumes that the PBOC has stopped selling silver as its stock levels are no longer “excessive.” Its remaining silver will play a role in diversifying China’s reserve portfolio away from US dollars, the firm notes.

Still, total supply has grown from 94.2 m/oz in 2002 to 281.5 m/oz in 2011, the firm reports.

This growth was largely the result of China’s decade-long GDP growth, which drove industrial development by averaging 10 percent annually. Rising commodity prices also accelerated exploration and development.

Mine production more than doubled during this time, increasing from 52.9 m/oz in 2002 to 104.6 m/oz in 2011. That growth is incidental as it was mostly due to China’s need to supply fabricators with base metals, GFMS explains. The volume of primary silver production in China is limited. 95 percent of its domestically mined silver originates as a by-product, mostly from lead-zinc deposits.

Despite this rapid supply growth, China experienced its first silver market deficit in 2002; that deficit grew to 23 m/oz in 2011. This gap has been filled in large part by hefty increases of imported base metal concentrates.

According to GFMS, since 2007, the largest source of silver supply in China has been base metals containing silver. Supply from that source increased from a mere 20.4 m/oz in 2002 to a peak of 150.3 m/oz in 2008.

China’s silver demand

GFMS states that China’s fabrication demand has grown about 12 percent per year from 2000 to 2011, representing a rise in offtake from 48.7 m/oz to 159.5 m/oz.

That is in stark contrast to the rest of the world, where fabrication demand has posted a double-digit fall over the same period, the report notes.

If China’s fabrication demand is viewed in segments, industrial demand is the largest slice. Within that segment, electrical and electronic applications represent the largest slice. Over the past decade, China has also become the world’s largest silver jewelry fabricator.

Growth in China’s investment demand is another notable development. With the liberalization of the market, Chinese investors’ participation has grown, elevating the nation from being “a marginal player just a few years ago … [to] the world’s leading market for both physical investment and paper trading” today.

An explosion in local precious metals purchases has been driven by macroeconomic conditions in China and abroad, states GFMS. For example, the firm explains that Chinese households have a great deal of cash savings that need to find a home. Yet the property market has been volatile and is now more heavily regulated, the stock market has seen heavy losses and interest rates on savings are close to zero in real terms.

Investment has traditionally been dominated by coins as silver bars were only made available in mid-2009. Last year, China accounted for 8 percent of global net purchases of these products.

Interest has also grown in silver contracts. The launch of silver contracts on the Shanghai Futures Exchange (SHFE) in May means that three exchanges now offer silver paper trading. GFMS notes that the SHFE has become an important commodity exchange for silver futures trading on a global basis, ranked only after the COMEX.

China silver outlook

As long as the outlook for economic growth in China remains positive, the nation is expected to continue playing a major role in the silver market.

Its use and production of base metals are slated for growth, which should result in an increase of by-product silver supply. GFMS also forecasts strong increases in production from primary sources as new projects are realized.

Growth in paper trading could be dramatic, the firm states. Further growth in coin and bar demand in upcoming years is expected as people place their trust in precious metals as a store of value and inflation hedge, notes the firm.

Urbanization and rising incomes also paint a bright picture for silver in China. As GFMS points out, the urban population only exceeded 50 percent in China for the first time last year. That compares to 80 percent in the countries that make up the Organisation for Economic Co-operation and Development and presents a bullish case for demand growth for silver-bearing products.

POSEIDON CONCEPTS CORP (PSN.TO)

Jag läste nyss Original Brailas blogginlägg om Poseidon "En fallande kniv för den spekulativt lagde"

Min idé att lägga årets 12000 på IPS-depå i Gold One ändrades därmed till att bli Poseidon då jag såg att kursen på kort tid backat från ca 15 cad och utdelningen till nuvarande kurs är häpnadsväckande 30%, på 0.09 cad/månad yield.






Så det blev ca 500 Poseidon ikväll på 3.23 cad
