We all heard about iPhone 4G and what happens when someone loses the prototype. There have been rumors revolving around the specs of the next iPhone but the question is that should we really call it 4G since we still don’t know if it will comply 4G standard. So what are the prospects if it does comply the 4G standard? Well here’s a quick comparison:

 

Technology

3G

4G

Frequency band

1.8 - 2.5GHz

2 - 8GHz

Bandwidth

5-20MHz

5-20MHz

Data rate

Up to 2Mbps

100Mbps moving - 1Gbps stationary

Access

W-CDMA

VSF-OFCDM and VSF-CDMA

FEC

Turbo-codes

Concatenated codes

Switching

Circuit/Packet

Currently iPhone 3G can support a maximum of 2Mbps datarate or what you call the ‘network speed’ but if it goes 4G then the speed increases over 50 times at least and this means you will be able to stream HD quality videos. I don’t think it could get any better.

So back to the news. OmniVision which manufactured 3.2 MegaPixel CMOS Image Sensors (we call them cameras) for iPhone 3G and 3Gs has now secured an order for supplying it’s latest top of the line 5 Megapixel cameras for the next iPhone due to be released in the second quarter of 2010. If this is true then Apple took consumer concern seriously about the pathetic state of the current cameras in iPhone 3G and 3Gs. This is definitely a huge improvement in image quality and experience.
