{ "item_title" : "MeshCore", "item_author" : [" Ernesto S. Flory "], "item_description" : "MeshCore is a practical guide to off grid mesh communication for situations where internet and cellular networks are unavailable. It explains how independent devices communicate directly, store messages, forward data across changing paths, and maintain coordination during outages, disasters, and intentional shutdowns.This book focuses on how mesh communication works in real conditions. It avoids theory heavy explanations and concentrates on behavior, limits, and operational decisions. The content is written in clear language and does not require a networking background.What you will learn in this book: What off grid communication means and why conventional networks failHow mesh networks are structured and how nodes interactHow message routing, store and forward, and delay tolerant delivery workHow to plan, configure, and expand a mesh networkHow power, range, and physical placement affect reliabilityHow communication behaves during power outages, disasters, and shutdownsHow identity, encryption, and trust work in decentralized systemsHow to troubleshoot common problems and avoid silent failuresWhat limits and tradeoffs exist in mesh communicationWho this book is for: Emergency preparedness and resilience focused readersField operators and response teams working without infrastructureCommunity organizers building local communication systemsTechnical readers who want a clear, operational understanding of mesh networksBeginners who want concepts explained without jargonWhy this book exists: To explain how communication works without internet or cell towersTo set realistic expectations about delay, reliability, and scaleTo provide a practical reference for planning and deploymentTo help readers avoid common mistakes that cause mesh networks to failTo support independent communication under real world constraintsMeshCore is not a marketing overview or a theory text. It is a grounded guide to how off grid mesh communication actually behaves and how to use it effectively when centralized systems cannot be relied upon.", "item_img_path" : "https://covers4.booksamillion.com/covers/bam/9/79/824/747/9798247475415_b.jpg", "price_data" : { "retail_price" : "25.00", "online_price" : "25.00", "our_price" : "25.00", "club_price" : "25.00", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
