Emergency Communication Wireless Transmission Topology

3.1 Fiber Resource Constraints

Base station backhaul and large-enterprise access projects frequently face insufficient fiber resources and saturated fiber core utilization. New fiber deployment entails lengthy construction cycles (typically months), complex multi-agency permitting (municipal, road authority, etc.), and high investment costs - severely impacting service provisioning timelines. In challenging terrain such as highways, mountainous areas, and water crossings, fiber construction may be entirely infeasible.

3.2 Diverse Service Types and Stringent Carriage Requirements

Operator transmission networks must simultaneously carry multiple service types: base station backhaul (high Bandwidth, low Latency, clock synchronization support), enterprise data leased lines (high security, high reliability), video surveillance backhaul (large Bandwidth, continuous stability), and voice communications (low Latency, low jitter). These diverse services impose significantly different requirements for Bandwidth, Latency, reliability, and security, demanding exceptional comprehensive carriage capability from the transmission system.

3.3 Rapid Deployment and Emergency Response

In emergency communication scenarios, link activation speed is often the top priority. Major event support, natural disaster emergency restoration, and sudden network outage recovery demand that communication equipment be transported, installed, commissioned, and placed into service within hours - requiring true plug-and-play rapid deployment capability.

3.4 Transmission Security and Reliability

Government and enterprise customer services as well as base station backhaul links carried by operators impose stringent requirements for transmission security and reliability. Wireless links must deliver carrier-grade stability and encryption, and in certain scenarios wireless links must operate in active/standby redundancy with existing fiber links, enabling seamless switchover protection.

4.1 Overall Architecture

BodaCOM provides a two-tier wireless architecture for operator emergency communication and wireless transmission scenarios - "Point-to-Point Backbone Transmission + Point-to-MultiPoint Service Access" - flexibly adapting to diverse service carriage requirements:

Point-to-Point (PtP) Backbone Transmission: For base station backhaul, cross-region data interconnection, and similar scenarios, BodaCOM ultra-long-distance Point-to-Point equipment builds high-Bandwidth Backbone Links. Per-link net throughput reaches up to 800 Mbps, with PTN equipment access and transparent clock transmission support, plus minimal Latency - serving as an equivalent replacement or hot-standby route for fiber links.

Point-to-MultiPoint (PtMP) Service Access: For large-enterprise access, business hall interconnection, and other multi-branch access scenarios, a Star Topology with one central base station serving multiple remote stations enables cost-effective networking - one central node simultaneously connecting multiple branch nodes.

Fiber/Wireless Redundancy Protection: Mission-critical service links employ a "fiber + wireless" diverse-path backup architecture, with BodaCOM wireless links and existing fiber links serving as mutual backups. When the primary link fails, the backup link automatically takes over - with zero service interruption during switchover.
