Waveforms can be modulated using an orthogonal frequency division multiplexing technique and can be simultaneously transmitted according to predefined transmission resources over a multi-sector broadcast paging channel reserved for such identical waveforms. Cyclic prefix can be added to the identical waveforms to mitigate problems associated with delay spread and/or time-of-arrival differences at or near sector perimeters."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-sector broadcast paging channel","description":"Systems and methods are described that facilitate improving paging signal strength at or near sector perimeters in a wireless network region by transmitted identical paging waveforms simultaneously fr","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8543138","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
