Anite offers 5G radio channel models

One of the main points of contention in the 5G race is which spectrum is best suited to deploy the next generation network – millimeter wave bands (mmW) above 6 GHz or in frequencies below 6 Ghz. Anite doesn’t take sides, but gives operators the tools they need if they decide to aim high.

The test and measurement provider has started leading the development of the first channel models for 5G – lab tests to predict how the wireless device will perform under real-world conditions – through the METIS (Mobile and wireless) program. communications Enablers for the 2020 Information) funded by the European Union. Society) in June 2014 and now announces that its initial work has been completed.

The Métis Group presented what James Goodwin, Director of Product Management at Anite plc, describes as a series of mathematical models for operators to assess spectrum and for handset and chip makers to assess the performance of their devices. prototypes of 5G devices. (See Anite Launches Basic LTE Packet Testing Tool and Anite Upgrades With 4G / 5G Virtual Drive Testing.)

The models were designed for things like system performance evaluation, system optimization, radio interface simulation and prototyping, R&D testing, and final product approval. METIS presents them via a map-based model, a stochastic model and a hybrid model combining the other two based on end-user scenarios, test cases and requirements mapped to various propagation scenarios.

Anite leads the channel modeling group at METIS, but it also includes vendors like Ericsson AB (Nasdaq: ERIC) and Nokia Networks, operators like NTT DoCoMo Inc. (NYSE: DCM) and Deutsche Telekom AG (NYSE: DT) , and a number of universities. (See SK Telecom, Ericsson Collaborate on 5G Research, and Ericsson Explores New Path to 5G.)

Goodwin says they didn’t set out to figure out which spectrum – above or below 6 GHz – was best for 5G, but to show the industry how to use the millimeter wave spectrum if they wanted to. This spectrum was not as sought after as the bands below 6 GHz where LTE-Advanced works, Goodwin says, so more work was needed. (See Spectrum Muddle at 5G Huddle and 60 GHz: a frequency to watch.)

“One thing around which there is a growing consensus is that it will be necessary to use some degree of new spectrum to release significant amounts of spectrum on a global scale,” Goodwin said. “It is unlikely that this is the mobile spectrum currently in use, but the behavior of the [high-band] spectrum is currently very poorly understood.

Goodwin concedes that it’s uncertain whether operators need new spectrum above 6GHz for 5G, but he sees a place for that with very high-speed small cell deployments. Small cells will be a crucial part of 5G, and while macrocells work well in the low bands, small cells are ideal for the high bands where increased capacity is needed.

“It’s always a fine line that we have to cross when you’re a facilitator in the industry to provide tools to other people rather than promoting one frequency over another,” he says. “The point was not to say ‘we recommend this frequency’, but to provide a basis for people to assess frequencies. There will be a lot of considerations that people take into account in determining commercial viability.”
