System-level design for 3G cellular development
RadioScape says its Radiolab 3G UMTS system-level design tool is the most complete set of design modelling elements available for this emerging cellular standard.
Receiver tests digital audio broadcasts
The quality of data transmissions broadcast via digital radio can now be monitored using RadioScape's latest professional test and analysis receiver.
This enables manufacturers to create DAB receivers that can receive Eureka 147 Band III and L Band, RDS and FM, making it the world's first global DAB receiver module.
"Canada and Germany are two of the countries leading the use of L-Band for DAB", explained Dave Hawkins, DAB Business Manager.
"Both are huge potential markets but manufacturers are reluctant to create L-Band only receivers because the market is still young and small.

Toolset accelerates 3G development
RadioScape has announced the worldwide availability of the RadioLab 3G 2.0 system-level design toolset.
By adding L-Band receiving capability to our module, manufacturers can have products that can be sold anywhere in the world.
This cuts design costs and simplifies inventory".
Another new feature is the inclusion of "rewind radio" that enables about 10min of audio to be stored in the on-chip RAM.
This can be used to listen to something again or time shift by pausing and resuming the radio.
As one of the world's experts in DAB transmission and reception technologies, RadioScape is uniquely positioned to be able to create optimised module designs that maximise the reception and minimise interference to achieve the crystal clear audio quality for which DAB is renowned.
This module enables manufacturers to easily make a high quality finished product with the addition of only a few items - power supply, case, speakers or headset, antenna, buttons and a display.
This module approach can reduce the time to create a new stereo DAB receiver from months to weeks.
The RS200L has been designed using the readily available DRE200 chip from Texas Instruments, which is one of the world's best selling receiver chips for the Eureka 147 standard, and other easy-to-obtain components so that it can be produced in high volumes with minimal risk to meet the escalating demand for DAB receivers, enabling DAB to become a mass-market technology.
Naresh Coppisetti, Digital Radio Business Manager at Texas Instruments, added: "Adding L-Band is an important enhancement to an already impressive module design that will open up new market opportunities, especially in Canada, Germany and France, where L-band DAB is just starting to take off.
The proven speed with which products can be brought to market using the RadioScape module and software approach will be significant in helping these markets to grow in a big way".
The single supply voltage of 5V and compact size of only 44 x 110 x 15mm, makes it compact enough to be used in battery powered radios as well as mains powered ones.
Prices for the RS200L module are around $40 depending on the volume ordered and optional features included, examples of which are Radio Data System (RDS), integral MP3 player software, infra-red remote control and I2C for external control of a CD transport.
The design of the module can be licensed if manufacturers wish to build it themselves.
Modules are available now.
