Well before the end of the year, two more carriers will have 95% (Vodafone) and 96% (Optus) population 3G coverage. The coverage footprints of each of these two 3G networks is larger than their GSM networks. By the end of next year, Optus will have expanded their network to 98% population coverage.The iPhone won't work with much of this expanded coverage as large areas are 900MHz.
Atom at 32nm won't even touch an ARM Cortex-A8 let alone a Cortex-A9 Atom is in-order, A9 is out-of-order. Think of an A9 at 32nm... Hmmm
Awesome now hopefully they PA Semi will be the first to release a Cortex-A9 quad core system on a chip. Apple originally designed this architecture with Acorn and part owned ARM, but sold them progressively off to get them through their rough patch. The Cortex-A9 gives today's desktop levels of performance in the 250mW class... Amazing. "The ARM Cortex-A9 MPCore multicore processor and ARM Cortex-A9 single core processor deliver up to 8000 DMIPS performance within a...
You are quite wrong, and if you read the article you linked to you explicitly lists the paired bands for each spectrum. There are two different frequency bands for the uplink and the downlink. 1900/2100 is the predominant worldwide pairing for 3G 1700/2100 is used only by T-Mobile USA The other pairs aren't that far apart and are only ever referred to by a single frequency. 1900/2100 is usually known as 2100 1700/2100 is usually known as 1700 All this information is in the...
Please update the image to take out references to the hypothetical HSOPA name which was used before development. (it was never the name of the air interface for LTE, if you must then call it E-UTRA) There is no reference to the work HSOPA in the entire 3GPP site! Please change UMTS-LTE to just LTE as LTE is now the primary upgrade path for both UMTS networks as well as CDMA2000. Please correct the speeds to the final speeds, not the goals which had to be exceeded for the...
A-GPS is real GPS plus extra Internet based features that enable a quick fix. There are so many errors in this article that it is laughable, as others have pointed out! In my old Nokia N95, it takes 3-5 minutes to get a fix without the Internet (GPS alone). It takes 5-7 seconds with data active. A-GPS downloads [Ephemeris and Almanac] information form the internet that is also broadcast via the satellites. The GPS satellites transmit at 50 bits per second which is SLOW....
The article is incorrect. Assisted GPS still requires a GPS receiver in the handset. It still requires the satellites to be in the sky. However it improves GPS performance such that it can be used in urban canyons. Assisted GPS downloads the ephemeris and almanac data over the internet instead of over the satellites, making positioning much quicker. The handsets internet connection (up to 7200000bps) is much faster downloading this information than the 50bps GPS...
They are the same size as the touch screen panels from the already released Samsung F480 and F490. Check them out as to what you can fit into a phone smaller than the iphone!
i really doubt that 5 + 4 refers to anything like that.... but i could hope that these are the five: high quality camera - if samsung has on sale 5 megapixel autofocus 7.2Mbit HSDPA phones with flash and full touch screen that are thinner than the iphone, apple should be able to. (F480 and F490) gps - gps now has minimal cost and battery life impact and ties into core location in the SDK perfectly video conferencing - every 3G phone has had a second camera with video...
