The principals at Softwave Wireless believed there was a market for a ray-tracing model that was accurate and easy to use – as long as its calculations were fast. Early customer selection by a Tier 1 operator suggests they were correct. The relationship between Softwave and LuxCarta allows both to focus on their strengths: R&D for Softwave Wireless and account management and customer support for LuxCarta. WPM enters a crowded market of RF prediction models, but separates itself on a number of fronts.
Speed
The first ray-tracing model was developed about 20 years ago for use on the first planning software. A number of third party models have been developed since then with differing levels of success. As RF planning and optimization becomes a 3D problem in dense urban environments requiring indoor coverage, and with small cells requiring higher-resolution data, the need for accurate and fast modeling is enjoying a renaissance. WPM can generate a 2km prediction, on 5m resolution data with vertical diffraction and horizontal ray tracing, in a few seconds. Engineers that used earlier versions of ray-tracing models should consider this model independent of their historical perspective; we think they will be pleasantly surprised by the calculation speeds.
A Perfect Complement to LuxCarta Geodata
Geodata is a critical input to any RF propagation model. WPM benefits from the x, y and z accuracy of City Planner data sets while also delivering tremendous accuracy using cost-effective Urban Planner 2.5D data. The model will work with any range of geodata layers as inputs. Ideally, in dense urban environments it benefits from building polygons, vegetation, clutter and of course a DTM. However, outside of dense urban areas, the propagation model can achieve impressive results with 2.5D and 2D geodata.
Support for Leading Planning Software
WPM supports Mentum Planet® and Teoco's ASSET. By having a product that is tightly integrated into the planning software, end-user training and support requirements are minimized.
A Premium on Usability
Ease-of-use is a typical requirement with most software, but the complexity of RF planning in dense urban environments amplifies the issue. WPM was created for use by engineers for dense urban planning, as well as for use in suburban and even rural morphologies. The product provides good "out-of-the box" accuracy, which can be improved through intuitive calibration.
Accuracy
Accuracy is the reason engineers invest in advanced propagation models and high-resolution geodata in the first place. It's the effort to reproduce the real-world environment, to get as close as possible to the RF reality, that delivers the return on investment in these products. Our tests have provided results that are stunning: calibrated RMS values are below 6 dB for small cells in urban and suburban environments. For regular cells, calibrated RMS values from 5.7 to 7 dB have been achieved. Most engineers will acknowledge that any model can deliver accurate results in a controlled setting, but we've encountered similar results in multiple areas and in different morphologies (i.e. dense urban, urban and suburban).
Many of our customers around the world have been seeking a cost-effective method of planning their broadband and LTE overlays. LuxCarta's partnership with Softwave Wireless, in conjunction with our strong relationships with planning software vendors, allows us to deliver the technically-advanced WPM propagation model and geodata uniquely optimized to work with it.
