Which type of cellular service can suffer interference caused by leakage from broadband cable networks?

• A. LTE
• B. WiMAX
• C. NFC
• D. Bluetooth

Answer: (A)

RF leakage from broadband cable networks can introduce unwanted energy into nearby radio bands, and cellular services that rely on clean, licensed spectrum are most affected when that energy leaks into or near their operating frequencies. LTE uses wide, licensed channels across multiple bands and is designed for reliable wide-area coverage, so external RF noise from cable leakage can degrade signal quality, cause errors, and slow data speeds. Short-range, low-power technologies like NFC and Bluetooth operate in near-field or widely separated, specific bands and are far less likely to be impacted by distant leakage. WiMAX could be affected in principle, but LTE is the typical cellular service most subject to this kind of interference in ordinary scenarios.
