Traditional Solutions (4G/5G)

· Blind spots will exist because theycan't be easily adjusted in accordance with the environment and progress of thebuilding site. As the projects in developing forward, new blind spots, such asdeep pits and underground drains, will also easily appear. The deployment ofsafety detection sensors of all types is complicated, and their maintenancecosts are expensive.

· Public cellular network; trafficcharge required

Landlink

· Full wireless deployment enables instantaneous use of the power on, flexible deployment in accordance with thesite environment and building progress, full-area network coverage that isavailable 7 days a week, around-the-clock, highly accurate positioning, and other fundamental services.

· No traffic charges, free dedicatednetwork

Traditional Solutions (4G/5G)

· After construction starts, someareas -- such as those below the ground -- are left without signal coverage due tothe base station's signal propagation model.
‍
· The 4G/5G network, which penetratesthe Internet, transmits sensor data to the server with a significant network latency of about 30–50 ms.

Landlink

· Dedicated network with flexible deployment to suit site building requirements, such as steep terrain or deeppits.
· Data from the dedicated network isdirectly returned to the server, with low network latency <1ms

Traditional Solutions (4G/5G)

· When sharing signal bandwidth with nearby residents and construction site workers, the issue of ordinary users consuming excessive bandwidth and causing service instability arises. This setup fails to meet the stringent requirements for building safety scenarios, which include the use of multi-channel HD cameras, AI-powered monitoring and analysis, and underground drainage detection.

· Additionally, the system lacks self-healing capabilities on construction sites. Consequently, if a base station experiences a failure, it results in a complete interruption of service, highlighting the need for a more robust and reliable communication infrastructure.

Landlink

· The equipment establishes a dedicated network, independent of nearby networks, guaranteeing the availability of over 200M of bandwidth to reliably support all operational scenarios at construction sites.

· Furthermore, the base station hardware is equipped with wireless backhaul self-healing features. In the event that one base station ceases to function, the two adjacent base stations will automatically establish a connection to restore service continuity. This ensures that any service disruption is brief, typically not exceeding 60 seconds.
