Global geodata provider to the wireless ecosystem, LuxCarta, announced it is providing specialised geodata designed for use with RF planning simulations at high frequencies to Telefónica Deutschland and Samsung for their first 26GHz tests in Hamburg. LuxCarta is providing two meter resolution City Planner building models, along with specialised vegetation layers, terrain and clutter for the Hamburg city centre and another suburban test area.

“5G networks that utilise mmWave frequencies require more precise geodata for RF simulation planning than any previous generation of network technology,” said Thomas Riedel, Head of Samsung Networks Europe. “By using LuxCarta’s specialised geodata – including individual trees – we are able to model the performance of our equipment prior to its deployment and on-air testing with Telefónica.”

Millimetre wave (mmWave) frequencies are being considered in trials and preliminary network implementations of 5G networks around the world. Unlike traditional wireless networks utilising frequencies less than 2.6GHz, mmWave frequencies are substantially impacted when they encounter obstructions. For this reason, it is necessary to account for each individual tree when creating the RF plan with these high frequencies.

Mads Leth-Espensen, head of Access Network Technology at Telefónica Deutschland, added: “We are happy that LuxCarta has created a geodata solution delivering a close proximity to the environment for real wave propagation at 26 GHz which is actually needed for an accurate modelling of 5G networks used by Telefónica Germany for example for Fixed Wireless Access trials.”

LuxCarta has been the preeminent producer of high-resolution 3D building data in support of RF engineering for many years. The company has also innovated in the creation of new types of geodata, including 2.5D clutter heights, population maps and 3D tree models for 5G.

Albéric Maumy, Managing Director of LuxCarta, stated: “We’re happy to support our long-time customer Telefónica, and partner Samsung, as they prepare for 5G. We continue to invest in R&D and improving our production processes to support the wireless ecosystem as it evolves toward this important new technology.”
