Understanding WCDMA

3G technology also comes in various forms and platforms. Understanding the major ones will help you decide which one is the right tool. You should also tell the technical details, to know if you are getting the right kind of efficiency and accessibility. Getting information from the internet other various sources will never be as convenient as fast, since 3G is the newest available. There are new developments and changes as well to get you ahead.

Knowing WCDMA or UMTS

W-CDMA wideband code-division multiple-access is among the major technologies that implement the 3G or third generation cellular systems. This is founded on the radio access technique suggested by the ETSI Alpha Group. The details and specifications were finalized in 1999. The implementation of W-CDMA is going to be a technical challenge due to the complexity and versatility. The sophistication of the of the systems of W-CDMA can be seen from various aspects.

These are namely the complexity of the overall system, computation complexity of the receiver and the complexity of ever single algorithm. W-CDMA link-level simulations or more than 10 times the compute intensive compared to 2G simulations. In the interface of W-CDMA, the different interface users can immediately transmit at varying information rates, with the data rates even varying in time. Networks of the UMTS are required to support every 2G service, plus new services and applications.

The Technical Details

As for the FDD technical summary, the frequency band will range from 1920 MHz up to 1980 MHz and 2110 MHz and 2170 MHz or frequency division duplex. The minimum frequency band needed is 2 x 5 MHz. The frequency re-use is 1. Carrier spacing is between 4.4 MHz and 5.2 MHz. The most number of voice channels on 2 x 5 MHz is 96 with a spreading factor of 256 UL and AMR or 7.95 Kbps and 98 with a spreading factor of 128 UL and AMR of 12.2 Kbps.

Other Specs

The voice coding includes AMR codecs ranging from 4.75 kHz up to 12.2 kHz, GSM EFR is at 12.2 kHz. SID is also included at 1.8 kHz. The channel coding includes convolutional coding with turbo code for high rate data. The duplexer required is 190 MHz separation with asymmetric connection supported. Tx and Rx isolation is MS:55db and BS:80dB. The Receiver is Rake, while receiver sensitivity is Node B.

More Information

Data type for the device is packet and circuit switch. Modulation is QPSK and pulse shaping is root raised cosine, rolling off at 0.22. The chip rate is 3.84 Mcps while the channel raster is 200 kHz. Maximum user data rate on the physical channel is 2.3 Mbps with a spreading factor of 4, and parallel codes of 3 DL / 6 UL, with limited interference. HSPDA will provide data speeds going as fast as 8 to 10 Mps and 20 Mbps for MIMO systems. The channel it rate is 5.67 Mbps with a frame length of 10 ms or 38400 chips.

There are 15 slots or frames, and 2560 chips. Handovers are soft and softer, plus a hard interfrequency. The power control period has a time slot with a rate of 1500 Hz. Power control step size is 0.5, 1, 1.5 and 2 dB while power control range is UL 80 dB and DL at 30 dB.

Website Building Tools

If you interested in website building for your home business, here are some great tools you might find useful to learn how to earn online, step by step. These are the tools that I use after checking out a lot of tools in the market. Hope it helps you in some ways:

1. Site Sell University

If you aren’t familiar…CHECK IT OUT! If you are… Congratulations!

Site Sell University will offer you a goldmine of information about “pre-selling” your customers and, in my opinion ( and I don’t endorse too many businesses this strongly), they have the best web hosting service on the planet for new startups, complete with mailing list features, newsletter integration, promotional tools… and much more.

I have to be honest with you. When I first came across Site Sell University, I was very excited to try it. A lot of ordinary people were raving about it. I thought if they can do it, I can do it, too.

My excitement fizzled out after a while. The reason being, I wasn’t very focused with my goal. However, after thinking about it and resolving to Take Action, I saw great results. That’s why I’m very very thankful I found Site Sell University and I’m not ashamed to tell the whole world about it. Check out this video to learn about Site Sell University in just 3 minutes.

2. Maverick Money Makers

If you are a novice at making money online, Maverick Money Makers is one site that you might want to check out to learn step by step methods. I’m a member of this private money making society online and I have learned many things from it.
