There are numerous platforms or types of 3G technology. Each manufacturer has made and developed some of the most cutting edge products and mobile handsets. The CDMA2000 is among the three major types. It has different features and tools also that will surely give you a whole new experience, unlike other technologies before it. Here are the details regarding how to make the best from the blueprint.

The CDMA2000 blueprint was made and developed by the 3rd Generation Partnership Project two or 3GPP2, which is a partnership that is composed of five telecommunication standard bodies : TTC and ARIB in Japan, TTA in Korea, TIA in Northern America and CWTS in China. CDMA2000 has been implemented to a lot of networks as an evolutionary step from CDMAOne. CDMA2000 gives a full backward compatibility with IS-95B.

CDMA2000 isn’t contained only into a single IMT-2000 and, though bosses have the capability to overlay ACDMA2000 1x system. The system backs 144 Kbps right now with info rates running up to 307 Kbps in the future, over the other present CDMAOne network.

CDMA2000 1xEV is the other name of the evolved CDMA2000. This technology will be implemented via a number of steps, namely the 1xEV-DV and 1xEV-DO. 1xEV-DO which represents 1x Evolution Data only. 1xEV-DV represents 1x Evolution Data and Voice. The 2 1xEV CDMA2000 evolution steps will employ a carrier standard 1. 25 Mhz. 1xEV-DO will most likely be available for the operators CDMA2000 during 2002. The solutions for 1xEV-DV were supplied in 2004.

CDMA2000 3x and CDMA2000 1x EV-DO are accepted by ITU and IMT-2000 3G basics. CDMA2000 3x is some of what the ITU has called IMT-2000 CDMA MC or Multi Carrier. This uses a lower than five MHz range thru 3x 1. 25 MHz channels to provide speeds of more than two Mbps.

As for the summary of the CDMA2000, the frequency band can be any type or existing and. The minimum frequency band needed for 1x is 2 x 1. 25 MHz. For 3x, the necessary is two x 3. 75 Mhz. Chip rate for 1x is 1. 2288. For 3x, chip rate is 3. 6864 Mcps. The maximum user data rate for 1x is 144 Kbps at present and 307 Kbps in the near future. As for 1xEV-DO, the maximum rate is 384 Kbps to 2. 4 Mbps. The frame length is 5 ms, 10 ms or 20 ms. As for power control rate, it is at 800 Hz. The spreading factors are four 256 UL.

W-CDMA in 3G is known as wideband code division multiple access. It’s one of the primary technologies utilised for the realization of 3G cellular systems. It is founded on the radio access method give by ETSI Alpha group with the features and specifications finalized in 1999. The execution of W-CDMA will cover very technical details. The complexity of the systems can be seen from various angles. These include the complicatedness of the receiver, the complicatedness of the system and the complexness of the single process.

In W-CDMA, the interface allows users of 3G to immediately send and get diverse information rates. UMTS networks will need the support of all current 2G services and several new services and applications. You should consider if this will be the right technique for you.

Mac OS X 10.1 [OLD VERSION]

Mac OS X, Apple’s next-generation operating system, debuted to great enthusiasm, but ultimately left users wanting more: more speed, more applications, more usefulness. Sure, it looked pretty, but you had to boot up into OS 9 when it came time to do some real work. That has all changed with the recent release of Mac OS X 10.1. Improvements across the board within the operating system and support from numerous vendors have made OS X a viable upgrade. Internal improvements have brought the performance and reliability up to professional levels, while software from such vendors as Canon, Epson, and Hewlett-Packard make compatible a wide variety of printers and scanners. As soon as 10.1 was released, we upgraded our Dual G4/450 with nothing but positive results. With multiple hard drives on our system, we’re able to dedicate drives for booting into either OS 9 or OS X, thus ensuring backward compatibility. However, since upgrading over a month ago, the only times we’ve needed to boot into

By now you’ve probably already heard that last night Nintendo spilled the beans on the successor to their immensely popular DS portable gaming system. Well, spilled the beans maybe isn’t best way to describe their announcement about it, more like just cracking open the can and letting us have a whiff of what’s inside. In fact, here’s the extent of what they ‘announced’ regarding the new Nintendo 3DS.

Nintendo Co., Ltd.(Minami-ward of Kyoto-city, President Satoru Iwata) will launch “N intendo 3D S”(temp) during the fiscal year ending March 2011, on which games can be enjoyed with 3D effects without the need for any special glasses.

“Nintendo 3DS”(temp) is going to be the new portable game machine to succeed “Nintendo DS series”, whose cumulative consolidated sales from Nintendo amounted to 125million units as of the end of December 2009, and will include backward compatibility so that the software for Nintendo DS series, including the ones for Nintendo DSi, can also be enjoyed.

We are planning to announce additional details at E3 show, which is scheduled to be held from June 15, 2010 at Los Angeles in the U.S.

At this point all we can do is speculate on what the system will look like and how it will work, but no one had really predicted any kind of 3D being part of the new system’s functionality, even though it’s all the rage now. Of course given Nintendo’s history with 3D gaming systems, I’m going to try and remain cautiously optimistic about the 3DS, but so far I’ve yet to come across a glasses-free 3D display that didn’t leave me feeling woozy after just a few minutes. So here’s to hoping Nintendo has something really revolutionary up their sleeves while we count down the days until E3.

Since I got my iPhone 3GS a couple of months ago, I’ve been wondering when I would really benefit from its highly anticipated faster 3G capability. I finally got the answer, and as it turns out, the wait is far from over.

AT&T announced Wednesday details of its rollout plans for High Speed Packet Access (HSPA) 7.2 3G technology. This is the next generation of 3G, and it offers up to 7.2Mbps data connection speeds (as opposed to the 2Mbps and 3.6Mbps of the current 3G).

(This is, of course, just the theoretical number. Typical real-world downlink and uplink speeds will likely be less than that depending on location, device, and overall traffic on the local wireless network at a given time. Nonetheless, this promises a significant boost. HSPA 7.2 is part of the 3rd Generation Partnership Project (3GPP) family of technologies, which include GSM, UMTS, and the Emerging LTE technology. HSPA 7.2 offers backward-compatibility, meaning it also works with existing 3G and 2G devices at the lower device-specific speed.)

According to the announcement, the new speed will be available by the end of the year. Unfortunately, it’s available only in six cities in the U.S., including Charlotte, N.C.; Chicago; Dallas; Houston; Los Angeles; and Miami. This means the rest of the country, including the San Francisco Bay Area where I am, must continue to wait.

It’s unclear how long the wait will be for the rest of the cities, but the company says it plans to deploy HSPA 7.2 in 25 of the nation’s 30 largest markets by the end of 2010, and to reach about 90 percent of its existing 3G network footprint with HSPA 7.2 by the end of 2011.

While this is rather sad news for me, for most people it won’t mean much, as chances are your phone is not compatible with the higher 3G speed. Currently, the iPhone 3GS is the only HSPA 7.2-ready smartphone I know that AT&T offers.

However, AT&T assures that it will offer more compatible devices with the rollout of HSPA 7.2. The company expects to have six HSPA 7.2-compatible smartphones in its device portfolio by the end of the year, as well as two new LaptopConnect cards.

The rollout of HSPA 7.2 is part of AT&T’s plan to invest some $18 billion this year, of which more than two-thirds is going toward broadband and wireless. Key projects of this investment include, in AT&T’s words:

The single largest roadblock that prevents most people from picking up a PlayStation 3 is the price. Sony’s just taken that roadblock and shrunk it. You’re now $100 more likely to buy a PlayStation 3.

The Difference

The PlayStation 3 Slim is actually more similar to the current PlayStation 3 fat than you’d think. Sony has been slowly phasing out features in the PS3 for a while, dumping USB ports, dumping card readers and dumping the PlayStation 2 backward compatibility. So the step to a Slim, now, isn’t actually that steep, compared to what you’d get if you switched from a launch PS3.

What you do get with the Slim is a smaller size, a reduced power consumption rate and a lower price. The lower power usage partially comes from the 45nm manufacturing process, and provides a 34% decrease in power consumption. (It’s also 32% smaller and 36% lighter). And, the Slim adds the ability to bitstream Dolby TrueHD and DTS-HD audio, which only matters if you’re an audiophile with a modern sound system. You also get a new matte finish, which makes the console look less “premium”, but eliminates the crazy fingerprint and dust problem the original had. Overall, it’s a net gain in goodness.

The Experience

Because it’s basically the same console, the only differences you’re going to notice are audible ones. Like we said in our hands on, the disc drive in the PS3 Slim is louder than in the original PlayStation 3. Think of it like a laptop optical disc drive vs. a desktop optical disc drive. When you’re seeking around, it makes a louder grinding noise than its larger counterpart. This noise makes no difference in Blu-ray movie watching, since it’s all sequential, and is only occasionally encountered in games, especially since many game install bits and pieces to the hard drive.

Other than that, yeah, it plays the same PS3 games, and it watches the same Blu-ray movies.

The Takeaway

Think about the PlayStation 3 and the PlayStation 3 Slim like this. You have two wives (I don’t know, imagine you’re Bill Paxton). Ninety-five percent of the time, they both do pretty much the same things. One is slightly chubbier, the other is slightly svelter. The skinnier one is quieter most of the time, but can get yappy when she can’t find something. The thinner one also costs you a little less money, and…has a matted finish? This metaphor isn’t going anywhere good, but you get the point. They’re basically the same console, except now it’s thinner and cheaper.

So the only question now is whether or not you should buy a PlayStation 3 now, or wait until September for the PS3 Slim. Both options are $300, but if you want the ability to install Linux, you’ll have to get the PlayStation 3 fat. Then again, the three of you who want that probably already have a PS3.

By lowering the price and making a more economical console, Sony’s finally more or less evened the hardware landscape with Microsoft, and continued to ensure that the PS3 is still the best-value-for-your-money Blu-ray player. Now all that’s left is getting some more games on there. [Amazon]

Lighter, thinner, less power hungry


Way less fingerprinty


Matted finish and new “squarer” styling might appeal to some, repulse others


Needs a $24 stand to be stable in the vertical position


Continues the tradition of removing features (USB ports, backward compatibility, Linux support) in the PS3 to lower the price

It seems like each year there is some new advancement made and the technology keeps improving day by day. Currently the biggest evolution is the Blue ray technology. But before talking about that, it is better to learn more about the Blue ray disk and Blue ray drives. The Blue ray disk is an optical disk that consists of a ferromagnetic material that is sealed with a plastic coating. There are various types of optical disk drives and some of the famously known one’s are the Blue ray drives.

The Blue ray drives enable the reading and writing of data on to a Blue ray disk with storage capacities of 25GB to 50GB. Unlike other disks, the Blue ray disks are readable and writable on both sides.

The way the Blue ray drives work is quite fascinating. The Blue ray drives have a laser inside it. The computer can actually read and write data on to a Blue ray disk because of this laser. During the whole disk reading process, a laser beam is projected on the disk. This reflects a light. The light changes according to the different effects of the magneto-optical Kerr.

The BDA, also known as the Blue ray Disk Association consist of some of the well known consumer electronic giants. According to them almost all Blue ray drives should be capable of reading the traditional type of DVD’s and CD’s. This is known as backward compatibility.

Although many consumers still use the standard DVD’s and CD’s to watch movies and listen to songs, the Blue ray disk format has gained more popularity over time. This is mainly because of its high storage capacity and outstanding performance. Who would want to purchase a traditional DVD that can store only up to 10GB instead of buying a Blue ray disk which can store between 25GB to 50GB?

During the early days there were a few manufacturers who released products that had Blue ray DVD players and Blue ray drives which could play only DVD’s and not CD’s. But today, many companies have rectified this problem by improving the quality of their products. These days you will be able to purchase Blue ray drives and players that can read DVD’s as well as CD’s.

Large data amounts can be archived with the help of Blue ray technology. If you check with the latest models, you will notice that Blue ray drives are being incorporated in almost every laptop and desktop computer. Many computer systems are now being shipped with the Blue ray drives installed in them. The Sony Playstation-3 was one of the first to use the Blue ray technology.

For manufacturers of traditional DVD’s and CD’s, the Blue ray disk has come up as a major competitor, enveloping most of its customers. After all who would want a DVD with low storage space when a Blue ray disk can be purchased with higher storage space and more features?
