Public Questions & Answers

APN name should match the carrier exactly, including capitals, dots and spaces; if required, also check any username and password. Make sure the APN you configure matches the service type (public, private or corporate) and that automatic APN detection isn’t pulling a consumer setting. Also verify the SIM is provisioned for data and that the carrier supports the required bands or service type. If possible, test the SIM in a known-good device to confirm serv…

Precise failover timing depends on several site-specific factors: the exact router model and firmware, how often health checks run, the failover thresholds you configure, and the characteristics of your primary and backup links (shore Wi‑Fi, fixed cellular, etc.). The variation in hardware and carrier means the numbers can differ from one installation to another. To forecast accurately, we need to review the exact equipment and network environment with Com…

Capabilities depend on the router model. Some Comset industrial routers offer built-in automated directional testing that can log RSRP, RSRQ, SINR, and throughput and run repeat tests from fixed mounting points. To know exactly which models support automation and how to enable it, check the model’s manual or ask Comset for the current model data and enablement steps. If your current model doesn’t support automated testing, you can still set up periodic man…

Yes. Some routers include built-in diagnostics that can log signal measurements such as RSRP, RSRQ and SINR, plus throughput, for different directions. If your device supports it, you can schedule repeat tests to run from the same mounting points and compare results later instead of doing each test manually. To run automated tests effectively, keep the antenna and coax length the same for every direction, test at similar times of day, and record multiple m…

Shore Wi‑Fi and cellular can be combined by using the router’s multi-WAN features to prefer shore Wi‑Fi when usable and switch to cellular automatically. This usually presents one stable onboard network to devices so they don’t need to reconnect as the vessel moves. There can be a brief failover delay as health checks detect a failure on the primary link and switch to cellular. In practice, most setups aim to minimize disruption, but some long-lived sessio…

Even if you can't share every detail, you can still get a useful baseline plan by supplying what you can and clearly noting gaps. Give us: the job the router must do, the site address or rough location for testing, every device that must connect, required interfaces (Ethernet, Wi-Fi, serial, GPIO/relay), expected data use, available power and enclosure, operating temperature, uptime needs, who will manage the unit, how many similar units you expect, and wh…

Key features include automatic WAN-to-VPN tunnels, dual-SIM for failover, and reliable health checks so the tunnel recovers quickly. Be mindful of NAT: with cellular NAT, inbound connections may not reach the remote site. You might use an outbound VPN to a central server or overlay networks, and plan firewall rules to limit exposure. We can help you pick models that support these patterns and validate SIM/carrier constraints; we can provide a recommended t…

As you noted, test each candidate spot for several minutes with the same antenna and cable length, under similar conditions. Run repeatable tests per location to observe how performance holds up, not just a quick snapshot. If possible, repeat tests at different times of day or during busier periods to capture potential carrier variation. Compare locations using sustained metrics like throughput, latency and jitter over the test duration, and pick the spot …

Describe the test scenario and outcomes: what you disconnected (the primary WAN) and which services you watched (critical applications, VPN, and remote management). State whether each service remained reachable during the switch and whether VPN paths stayed secure. Record the backup SIM status and any hardware checks: confirm the SIM is active with data and uses the correct APN, and note whether any antennas were tested or adjusted during the test. Documen…

During a controlled failover, capture: failover latency (time from primary WAN loss to traffic on cellular), downtime duration, and whether critical services remained reachable (VPN, remote access, monitoring, essential cloud apps). Verify the backup SIM was active, had data, and used the correct APN, and confirm external antennas or MIMO paths were functioning during the switch. Ensure remote management stays accessible over cellular, that alerts and logs…

Share a concise incident snapshot: router model and firmware version, SIM carrier, site location, and the LED states you observed during the fault, plus the fault time window and any status messages. If you can, export or screenshot the diagnostic data (or export the router log file with timestamps) and send that along with steps to reproduce. Include whether the issue follows the SIM or stays with the hardware so Comset can distinguish provisioning or cov…

Collect time-aligned readings: RSRP, RSRQ, SINR, current serving band and cell ID, registration state, and the assigned IP; note data counters and the exact timestamp. Also capture WAN health-check results, last reboot time, power events and SIM switch events, plus any error messages. Export to CSV or use the router’s export function and share the file with Comset so we can tell whether the issue is radio quality, antenna path, or configuration.

For each shortlisted model, check them against your five non-negotiables: carrier and bands, required interfaces (LAN, Wi‑Fi, serial, GPIO, GPS, PoE), power and environmental limits, uptime/redundancy, and remote access method. Ensure every model meets these essentials before weighing other factors. Then compare deployment practicality: antenna mounting options, cable length and losses, remote management capabilities, firmware and support lifecycle, and to…

Once we have your practical site picture, Comset will propose a complete router/antenna kit tailored to that site, not just a single device. The kit will be selected to match your environment, interfaces and remote-management needs, and will take mounting, power, and protection requirements into account. You’ll typically see a package that specifies a suitable industrial router, the antenna system (including any MIMO considerations), mounting hardware or e…

On-site data to collect includes which carriers work there, which 4G/5G bands are available, and real signal quality metrics (updatesI, SINR, observed throughput) at the router location. Note any obstacles like walls or metal structures that affect reception. Usage profile matters: list every device and interface (LAN, Wi‑Fi, serial, GPIO), expected data volumes (peak vs average), and what needs remote access or VPNs. Also capture uptime requirements and f…

After you share the practical site picture, Comset reviews your inputs and returns a focused recommendation that identifies the best-fit model and the exact deployment requirements. Expect explicit guidance on the chosen router, the necessary interfaces and power/environment constraints, and any uptime considerations or caveats for your site. If some details are still uncertain, we may ask a quick clarification to tighten the fit, and we’ll outline the nex…

On-site testing should focus on isolating variables and capturing comparable metrics. Use the router’s status page to record signal strength and connection stability, plus observed data throughput for each configuration. When swapping a known-good antenna, test at the same location with the same cable length and mounting setup, and document the before/after results. Repeat tests with the same router and a different antenna, then swap back to confirm repeat…

To compare 4G and 5G sensibly, start with what your site needs today and what it may need tomorrow. Gather data on typical and peak data use, how many devices and interfaces will connect, and whether you require VPN or remote management. Also capture uptime targets and how quickly you must recover after a link outage. Then verify carrier coverage and the bands available at the site, because 5G benefits depend on the network and hardware supporting the righ…
