Iphone 5 facing problems staying connected with ATT LTE

I was one of the early adopters of iPhone 5, got it through pre-order on day 1. I badly wanted to get back to ios after some difficult time with Galaxy S2 on ATT (Part of it was battery drain in the Samsung ATT custom build of Android).

It has been a smooth ride with iPhone 5,  some new after features and a better camera etc.  But once in a while my mails would stop arriving, I have 2 exchange and Gmail configured. When I’m out with my family, I will suddenly realize that  I’m not receiving mails anymore. On closer look iPhone would have lost the data connection, and it wouldn’t pick up LTE, till I restart the phone.(Restart  & Apple no way right 🙂 ).

 

Iphone 5 LTE

On the other hand none with Galaxy S3 had the same issues,  and once few other of my colleagues got the new iPhone 5 did we find that it common to all iPhones,  Local ATT suggested switching off LTE. The phone is now doing fine on 4G, but  with LTE the device couldnt stay  connected.

So anyone else from other cities facing the same problem??

T-Mobile and Nokia Siemens working on 650 Mbps 3G Standard

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.
