Daily dose of IT ,Hardware , Cell phones and other technology
ATT has confirmed that after March 11 (iOS update 4.3) iPhones running in ATT network should be able to support wifi tethering and allowing other devices to use ATT network through iPhone as wifi modem.
The addition was expected as Apple announced the same for ipad 2 during its launch. The iOS 4.3 update unlock it for the all the iPhone 4 devices.
T-Mobile and Nokia Siemens have joined for working on this 650 Mbps 3g standard which is likely to be completed by 2013, this project is based on LT-HSPA evolution basically for offering more high speed downloads at the rate of 650 Mbps and above which is now 42 Mbps. HSPA is the High Speed Packet Access which is the standard for wireless broadband defined in 3GPP and is a consolidation of two telephony protocols used for the improvements in WCDMA.
This increase in the downloading speed is got / achieved by combining eight channels into a single data link this increases the cell edge data rate along with dual antenna basically HSPA+ (which gives a HSPA data rates 56Mbps down link and 22 Mbps up link through MIMO -Multiple Input and Multiple Output) ie., dual channel sending data to and fro at the same time. The technology also enhances the 4g broadband from what it has been planned now. The specifications workings are to take place using radio access network, which is already working on Nokia Siemens single RAN platform which is compatible with its present WCDMA (Wide band Code Division Multiple Access – is a interface standard found in 3g mobiles) and HSPA mobiles.
Nortel is a Canadian telecom company once a giant in its field with more than 90000 employees has now come to auction due to its bankruptcy. The company is auctioning its patents, there are more than 4000 patents coming into auction which are grouped into six categories so that many companies can buy their patents instead of a single company getting all their patents.
Apple and Google are participating in the bid. The auction also contains the 3g and 4g patents which draws these companies into the bid yet they have not disclosed their bidders. There is also an estimation that the patents are of a billion dollars worth. Since Apple is facing lots of litigations this auction might be a useful thing in this time. The 4g is a cellular wireless standard which is fully secure Internet protocol based mobile broadband for laptops, smart phones and etc, it has a downloading speed of 100 Mbps for fast mobility communication and 1Gbps for slow mobility communication, previous versions were the pre-4g mobile WiMAX and first release 3g long term evolution. Norton was also one of the first firms to have this WiMAX technology.
