Atoll™, the leading radio network planning tool from Forsk, includes HSDPA modelling and simulation capabilities. HSDPA (High Speed Downlink Packet Access) is a key feature for 3G WCDMA networks turbo-charging the speed with which users can download attachments and enjoy advanced multimedia services through the use of advanced techniques including Adaptive Modulation and Coding (AMC), Multiple-Input Multiple-Output (MIMO), Hybrid Automatic Repeat Request (HARQ), fast scheduling, fast cell search, and advanced receiver design.

The integration of HSDPA capabilities in Atoll™ version 2.4, released in the first half of 2005, was achieved via a joint development programme with key customers that ensured that the features included in the software addressed the real problems facing mobile network operators.

Atoll™ HSDPA features include HSDPA equipment modelling, AMC (Adaptive Modulation Coding) modelling, Ec/Nt HS-PDSCH prediction plots, CQI prediction plots and RLC throughput prediction plots. These features have been further enhanced in the new version 2.5 with a combined Release 99/HSDPA Monte-Carlo simulator that takes account of AMC modelling, HSDPA dynamic power allocation and HSDPA user scheduling.

Atoll™ was the first UMTS radio network design tool available on the market in 2001, and ever since then has stayed ahead of the competition. Atoll™ today has the largest share of the market for UMTS radio network design tools.

Forsk is an independent software company, headquartered in Toulouse France that has provided software solutions to the wireless communications industry since 1987. Forsk’s radio planning tool, Atoll™, is in use with leading cellular operators and equipment suppliers world-wide.
