Here is one way you can do that. Some of you might already be aware of this, but a good way to save up power is through your cellphone charger. People usually charge their cellphones while sleeping and you might think that once the cellphone has been fully charged no power is consumed (your charger starts cooling off too). Well, you’re wrong.
Charlie at Nokia conversations wrote in his lastest article that
” normal Nokia chargers draw about 150mA power when just plugged in and not charging a device (when the charger is on standby). ”
Compared to having billions of cellphones and chargers out there, thats alot of wasted power. Therefore, its best to unplug your charger once your cellphone has been fully charged. According to the article, Nokia is working on new chargers that will produce zero waste..
Keith Shaw from NetworkWorld demonstates the new portable GPS device called the GPS Snitch in this video. The device provides two-way communications between the GPS satellites and also has a GSM radio that allows two-way communications with servers so you can follow around anyone with this device in their vehicle as long as there is GSM coverage. Interesting..
I once read an article that refered to both a mobile carrier and operator in the same paragraph. And since then I was unable to get an answer to whether there is a difference between the two. As I understand, a mobile carrier is a mobile operator. I don’t remember where I read it so I can’t reference it now however, if there is a differenece between the two could you please let me know what it is?
Nokia announced in its recent press release the Nokia 6212 Classic which is an NFC-enabled cell phone. I haven’t heard much about NFC before so I looked it up on wikipedia.
Near Field Communication (NFC) is a wireless technology that allows communications between devices in the range of 10 centimeters. You might think of Bluetooth but with a shorter range and a faster set-up process. According to the press release NFC will simplify and speed up the way people interact and exchange information:
“With the Nokia 6212 classic, people can swap items like business cards or calendar notes by simply tapping their handsets together. With ever-increasing device functions and services available, ease-of-use is essential. One way to keep things simple is NFC.”
And according to wikipedia, NFC can be used in many applications such as mobile ticketing, mobile payment and blutooth pairing. I recommend reading both links for more information about NFC.
I have been wondering about something lately… With all the buzz about LTE and the fact that it might be deployed commercially by 2010, what about those countries that don’t have 3G deployed yet and some even don’t have the license to operate it either and its not because they are not developed countries, I am talking about major operators. I read recently that the migration to LTE could be done easily from any of the 3GPP technologies (GSM, UMTS, HSPA+) and that LTE would offer seamless handover to these technologies when user out of coverage. So maybe these operators are waiting to migrate directly to 4G. Although I haven’t heard of such a deal yet. I know there could be many reasons not to have 3G; price of services, price of license and installations, users’ requirements, ..etc. But my question is this: When operators did not invest in 3G then why would they want to invest in 4G? If they did decide to do that then it won’t be any time soon and until then the user can only buy the device that supports it but not operate it.
