Credeati ca iOS 4.2.1 aduce putine lucruri noi si importante pentru utilizatorii de iPhone? Ei bine think again! Si think hard pentru ca Apple a implementat in iOS 4.2.1 o tehnologie care noua care imbunatateste foarte mult performanta terminalului in ceea ce priveste interactiunea cu reteaua de telefonie. Tehnologia Network Controlled Fast Dormancy implementata de Apple in iOS 4.2.1 permite terminalelor sa functioneze mai eficient si sa reduca congestiile retelei de telefonie mobila. Iata si o scurta explicatie: cand un terminal conectat la o retea de telefonie intra in standby mode, conexiunea sa cu reteaua trece in idle state iar atunci cand telefonul verifica(prin push notifications sau servicii similare) daca exista un mail nou, ori un update pe Twitter, se conecteaza al retea si trece din idle in active state iar aceste deconectari si reconectari repetate duc la congestionarea retelei si la cresterea timpilor de raspuns.
Noua tehnologie implementata de Apple si testata de Nokia Siemens reduce aceasta congestie prin introducerea terminalului intr-o stare intermediara in locul celei idle si practic terminalul se conecteaza mult mai rapid si cere mult mai putine informatii de la retea pentru a obtine datele de care are nevoie. Aceasta noua tehnologie duce nu doar la decongestionarea retelelor de telefonie ci chiar si la cresterea autonomiei bateriei, unele smartphone-uri avand o autonomie cu pana la 11 ore mai buna dupa implementarea acestei tehnologii.
Nokia a implementat aceasta tehnologie in smartphone-urile sale inca de la inceputul acestui an insa ea functioneaza doar pe retelele compatibile si din pacate in Romania nu cred ca avem asa ceva inca. Oricum acesta este un foarte foarte mare pas facut de Apple si e posibil sa il vedem prezentat ca un feature al urmatoarelor tablete iPad/iPhone-uri.
Smartphones connect constantly to the network, often driven by applications. But this creates a huge amount of signalling as smartphones switch from an idle mode to an active state so that they can interact with the network, for example to get emails or pull in the latest tweets.
When it has gathered the information it needs, usually working in the background so you don’t even notice it’s happening, some smartphones then switch immediately into the idle state in order to conserve battery power. So when you next want some data from the network, the smartphone has to reconnect. This involves the network and phone exchanging many small signals.
All this disconnecting and reconnecting takes time and can cause a frustratingly slow network response. On the other hand, leaving the smartphone in an active mode all the time drains the battery very quickly.
To overcome the problem Nokia Siemens Networks introduced a method that, instead of putting the handset into idle or keeping it always active, keeps the handset in an intermediate state. From here, a smartphone can wake up much more quickly and needs to send far fewer signals to and from the network to start a data connection. You get a fast network response and a longer battery life.
