Public Questions & Answers

Do a live-site throughput test. Measure sustained upload, latency and packet loss at the installed antenna position during typical busy periods. Run a short pilot with expected camera data patterns, log data usage, and model how many devices share the uplink and what headroom you need. Ask Comset to verify the bands and SIM service for the chosen model and confirm the plan supports remote-management features.

Interpretation should start from your baseline measurements and testing goals. Compare RSRP, RSRQ and SINR values, latency, jitter and throughput over time, looking for stability, not single-good readings. Define acceptable ranges based on your application needs (for example, a minimum usable throughput and a target latency). If current readings diverge from baseline, investigate changes in antenna position, band selection, or traffic load, and re-test to …

Start by listing current wired devices and likely additions over 12–24 months, and map them to ports. Add a small growth margin (e.g., 20–30%) and consider whether a separate switch is preferable for local devices, PoE, or VLAN separation. If you’re near the router’s port limit, a switch typically keeps growth simple and allows future expansion without replacing the router. Finally, check whether the router and future switch support the same management met…

Two different carriers usually provide the best redundancy because the whole point of dual SIM is to avoid a single carrier outage affecting your site. SIMs from the same network still have some value—for example, if one service has a different APN, billing arrangement, or priority, or simply for operational simplicity—but they do not offer the same geographic and network diversity as two different carriers. If you can't get two different carriers, you can…

Start with repeatable tests that reflect how you’ll actually use the router. Collect numerical readings such as RSRP, RSRQ and SINR, plus latency, jitter and real throughput for both download and upload. Note the serving band and cell, and test at different times of day to see how things vary. Use the same antenna and cable length you’ll deploy, and keep the test conditions consistent (same weather, time of day, and traffic load). Run several minutes of te…

That happens a lot. You can still get a useful recommendation by sharing what you can and clearly noting any gaps. We’ll propose a baseline solution and a plan to firm it up once more information is available. Focus on must-haves: the required interfaces, power and uptime needs, and the site address or rough location for carrier testing. We can sketch a starter model and deployment plan, then tighten it up as details come in.

Plan to compare two or three candidate mounting spots. Use the same antenna and cable length you plan to deploy, and test each location under similar conditions (same time of day and weather). Record the coax length and note any obstructions or shielding that might affect the signal path. Collect objective metrics: RSRP, RSRQ, SINR, the serving cell and band, plus latency, download and upload speeds, and jitter. Run repeatable tests for several minutes to …

Start by calculating per-camera data use and the number of cameras you’ll have. If you record continuously in high quality or stream video, uplink can be hundreds of gigabytes per month; event clips and occasional remote viewing use far less. Include audio, multiple streams, firmware updates and user access. Also decide if you’ll store video locally and push only substreams remotely to reduce uplink. Size the SIM plan for sustained upload capacity and head…

To tailor a self-install recommendation, share what the site needs to do: location, the intended carrier and SIM type, whether you’ll use 4G or 5G service, and the application plus expected data use and number of connected devices. Also list required interfaces (Ethernet, Wi‑Fi, serial, GPIO/relay/PoE), any GPS or VPN needs, whether you want dual‑SIM or remote-management, and the power, operating environment, antenna position and cable length. Explain upti…

Choose two carriers that provide real coverage diversity at your site. Look for networks with strong signal at the installation location and, ideally, different core networks. Consider practical differences that affect uptime: carrier plans, APN options, roaming rules, data caps, and how each SIM is billed. Also decide whether you want automatic failover or a manual switch, and ensure the router and management platform can enforce that policy. Plan a hands…

To help us pick quickly between a CM685V-6 (4G) and a CM950W (5G with redundancy), describe the actual site job and conditions. For example, tell us whether the installation is fixed or mobile, and what 4G/5G coverage you tested, plus the number and type of devices that will connect. Also list the required interfaces and features (LAN ports, Wi‑Fi, serial, GPIO, GPS, PoE), the expected data load, whether inbound remote access is needed, power and environme…

In practice, the choice comes down to actual traffic and growth expectations. Cat 4 can meet many sites’ needs, while Cat 6 adds headroom through carrier aggregation where available. Real results depend on the carrier, tower load, signal quality and antenna setup, so headline speeds aren’t everything. On-site checks to guide a decision include quantifying current data use and peak load, listing every device that will connect and the required interfaces (LA…

Start by confirming whether the installation is fixed or mobile and which network is available. Then decide on required interfaces and features such as LAN ports, Wi‑Fi, dual SIM or failover, serial, GPIO, GPS and remote management. With those basics clarified, the shortlist becomes practical rather than a spreadsheet headache, and Comset can help convert it into a usable recommendation.

Interface availability is model- and firmware-specific, so always check the exact router’s hardware interface list in the product manual. The documentation should specify which ports and pins are exposed and whether GPIO/relay features are supported in the current firmware. If you want, we can review your target models to confirm they provide the required interfaces before you decide.

Start by collecting time-series modem readings: RSRP, RSRQ, SINR, current serving band and cell ID, registration state, the assigned IP, and data counters (bytes in/out). Note the exact time and which carrier/SIM you’re using, plus any disconnect reasons shown by the router. Also grab router-side diagnostics: WAN health-check results, last reboot time, power events, SIM switch events, VPN or remote-access status, and any error messages in the system logs. …

Failover behavior depends on the exact model and configuration. A router with automatic WAN-to-cellular failover will switch traffic to the cellular path when the fixed NBN link is lost, and switch back when it returns. The timing and smoothness depend on the hardware, firmware and health-check settings you enable, so it can be effectively seamless or involve a brief interruption. Active sessions may be briefly interrupted during the switch unless you conf…

Heat is a key factor in cabinet installations. To verify the cabinet won't overheat during operation, check the router's operating temperature range, its power draw, and the cabinet's ventilation. If possible, estimate the expected inside temperature given the ambient conditions and any nearby heat sources, and confirm there is adequate airflow. Cabinet installations also need proper grounding, transient protection and separation from noisy electrical comp…

Deciding between 4G and 5G should be based on real-world needs, not just speed. Consider the actual data use, number of devices and interfaces required, uptime requirements, and whether VPN or remote management are needed. If the application is dependable but low to moderate bandwidth, a well-chosen 4G/4GX setup may meet the need more cost-effectively and with proven reliability. If higher capacity, more simultaneous connections, or future growth are likel…
