LTE in 2014 napisao:
1. LTE-A
Wide commercial LTE Advanced deployment
The number one prediction for LTE in 2014 is something of a ‘no brainer’, as Kevin Bacon would say. – LTE Advanced will become a commercial reality in several networks. LTE Advanced consists of several improvements over standard LTE, but the key one is carrier aggregation, enabling different frequencies to be combined and treated as one channel of bandwidth, delivering great performance. Demos have shown speeds of up to 300Mbps – doubling existing speeds.Not surprisingly, the South Korean’s are ahead of the game and deployed LTE Advanced back in June, with a special variant of the Galaxy S4 as the supported handset.In the UK, EE is trialling LTE-A in ‘Tech City’ in central London, with an aim to wider deployment in mid-2014. In Australia Telstra is also trialling, as is its sister company CSL in Hong Kong. US networks have been more coy about revealing an LTE Advanced timetable, but progress is to be certainly to be expected this year. In the world where there’s an ever increasing insatiable demand for data, LTE Advanced will provide a timely performance boost for networks (each E-UTRA cell will support up to four times the data and voice capacity supported by HSPA).
2. LTE-B
LTE Broadcast (Mobile TV, e.g.)
One interesting use of LTE that is looking like coming to the fore in 2014 is Multimedia Broadcast Multicast Service (eMBMS), more commonly known as LTE Broadcast. This is a method of serving multiple users with one video stream and should provide a much better video experience to LTE enabled handsets than conventional video streams. Rather than sending out a different stream to everyone on the cell tower of the same thing, the technology makes it possible for all users on the cell to tap into the same stream of data. It could be used for live concerts, sports events and when the world and its dog are downloading the latest iOS update.Verizon Wireless has already made noises that it is looking to use the 2014 Super Bowl as a test run, and Telsta is also talking about trialling it. Big players such as Ericsson and Qualcomm have also been playing up LTE Broadcast. The technology makes a lot of sense to us and we’re keen to see it implemented will in 2014.
Za samo godinu, dve, mnoge su se stvari iskristalisale.LTE in 2014 napisao: LTE – Big in Europe
LTE has been big in Japan, in the US, and of course in South Korea, but having the first commercially LTE network launch in December 2009, Europe has generally been slow on the LTE uptake. However, that’s set to change in 2014, with consultancy Northstream predicting a 50 per cent subscriber uptake in of LTE. A lot of this will have to do with the fact that much of the digital dividend 800MHz spectrum will finally have been released, and major auctions have also brought a lot of 2600MHz into play too. Big pushes such as Vodafone “Project Spring”, which will see $9 billion spent over three years, will push competition in 4G. With handset support now much more widespread operators are ready to launch LTE and make appealing service offerings, enabling LTE to move from becoming a niche to a mainstream offering in many leading European markets.
Izvor.Mreža za sve: Google planira da lansira hiljade internet balona
Projekat Loon želi brzu internet vezu da omogući balonima, a u videu navode da sada mogu ostati i 100 dana u vazduhu i da ih mogu proizvoditi mnogo brže.
Googleov projekat Loon već je nekoliko godina u razvoju, a za razliku od Facebookovih dronova, oni internet do nedostupnih područja žele da dovedu balonima. Projekat su testirali iznad Novog Zelanda, a sada ga žele proširiti na mnogo više zemalja.
Baloni lete na visini od 20 kilometara i koriste softver uz pomoć kojeg znaju gde moraju da pošalju određeni balon, u zavisnosti od strujanja vazduha. Za razliku od 2013. godine baloni danas mogu ostati u stratosferi i do 10 puta duže, a mnogi su u vazduhu bili i više od 100 dana. Rekord je, kažu u Googleu, bio 130 dana. Razvili su i automatski sistem, koji im omogućava da lansiraju balone mnogo brže.
"Cilj projekta je dovesti internet do dvoje od troje ljudi u svetu koji ga još nemaju," kaže Majk Kasidi iz Googlea. Dodaje da se približavaju trenutku u kom će moći da lansiraju hiljade balona. Uslugu testiraju i u Australiji i Južnoj Americi, a s operaterima sarađuju kako bi balonima omogućili LTE vezu.
