These two new classes of channel models emulate the temporal variations in the propagation channel by changing delay spread characteristics versus time. FLEX5 allows pre-defined 3G channel models to be recalled with the touch of a button. 3GPDP also provides the ability to go beyond the two-path dynamic models defined in these minimum performance standards by allowing all of its paths to be independently varied over time. The TAS 4600A Noise and Interference Emulator works in conjunction with the TAS 4500 to deliver accurate co- and adjacent channel interference conditions to ensure precise receiver performance characterization. The ability of a wireless receiver to mitigate sources of interference is critical to achieve the higher data rates third-generation technologies promise to deliver.
Lead time is six to eight weeks.
The latest development is cdma2000. The existing TAS 4500 and TAS 4600 together emulate the real world of RF propagation paths, replete with signal echoes, multipath fading, and phase shifting. By adding 3G features to that emulation capability, TAS's overall product suite becomes that much more attractive. This product should go a long way to help you design a more reliable 3G cellphone system, get it to market more quickly, and perhaps ensure it will pack the features necessary for reliable performance after deployment. Whether you're in a product development, design verification, test, conformance test, or product evaluation mode, you can use the 3GPDP's newest CDMA enhancements.
