The Need for External and Unexpected Internal RF Interference Mitigation

To counter the capacity strain on their networks, mobile operators have invested billions of dollars (USD) into spectrum licenses, RAN equipment, network optimizations and advanced technologies to ensure maximum spectral efficiencies. Despite these massive investments, operators today have minimal insights about the amount and effect of external and unintended internal RF interference within their networks. Operators have little information about the external RF interference that originates from outside of their deployed networks, including interference from networks in bordering geographies, emissions from industrial equipment and unauthorized devices/nodes/repeaters. Just as impactful, operators have little information about unintended internal RF interference, which originates from within their deployed networks but is not expected and is unaccounted for during routine network optimization. Sources of unintended internal interference include faulty equipment at a tower site (e.g. causing PIM), rogue UEs, and distant cells within the operator network via tropospheric ducting.

Operator networks typically experience external RF interference in 10% of cells and unintended internal RF interference in 5% of cells. Of course, the levels of RF interference will vary across operator networks depending on the network design and density, proliferation of unregulated equipment, efficacy of government spectrum regulations, country borders with discordant spectrum allocations, environmental conditions and a host of other criteria.

Without the necessary tools in place, these RF interference sources degrade network capacity and increase OPEX as operators struggle to address even the most obvious service impacting instances. The net result is a material adverse impact on an operator’s business. In the future, the magnitude of this problem will intensify with the need for clean spectrum to achieve the spectral efficiency targets with 5G and Massive MIMO as well as with the challenges of shared spectrum deployments. No mobile operator would think twice about protecting their offices with qualified security personnel, yet their most valued asset, licensed spectrum, remains unguarded - until now, with Spectrum Effect’s groundbreaking solution, Spectrum-NET.
