That depends on the exact model and the surrounding job. In broad terms, a CM820-series router is often part of a more industrial-style deployment conversation, especially where failover, stronger local interfaces or unattended service matter. A CM685-series model may suit lighter-duty or more straightforward jobs where the essential connectivity need is clear and the environment is less demanding. The useful comparison is therefore not series versus seri…

Start by removing the models that do not fit the site conditions. Ask what network is available, whether the installation is fixed or mobile, how many LAN ports are needed, whether Wi-Fi matters, whether dual SIM or failover is required, and whether serial, GPIO, GPS or remote management features are part of the job. Once those basics are clear, the list usually becomes much shorter. The mistake is to compare every specification line at once. Comset is us…

The real-world difference starts with the deployment outcome. The CM685V-6 sits in the 4G LTE Cat 6 part of the discussion, which can suit many stable business and monitoring applications. The CM950W brings the conversation into 5G and dual-SIM redundancy territory, which is more relevant when the site needs newer radio capability, higher performance potential or a stronger high-availability brief. In other words, this is not really a beauty contest betwe…

No, and that catches people out regularly. A router may appear impressive on paper yet miss important Australian carrier bands or regional coverage requirements. Even when it connects, it may not perform as expected if the radio design, certification or supported frequency set is a poor match for local networks. Comset’s advantage is that the Australian carrier environment is part of the recommendation process. That makes the discussion far more useful th…

Band 28 matters because it is widely used for broader area coverage in Australia and often plays a big role in regional 4G performance. In plain English, support for that band can be the difference between a router that works where you need it and one that only looks good in the city. It is not the only band that matters, but it is one of the most practical compatibility checks. Comset tends to bring Band 28 into the conversation because it is tied to rea…

The sensible way is to test before committing. Check signal quality, not just bars, from likely mounting points. Compare carriers where possible and pay attention to the practical path of the coaxial cable back to the router, because a brilliant signal location can be undermined by a long or lossy cable run. Comset’s cellular-tower and signal-testing guidance is useful here because good antenna placement is part radio planning and part common sense. The r…

Phone bars are a rough indicator, not a proper network assessment. Routers and phones may support different bands, antenna arrangements and carrier features, and good-looking signal strength does not guarantee good quality, low interference or adequate upload performance. That is why more meaningful figures such as RSRP, RSRQ and SINR are often used when testing router performance. Comset normally treats a phone as a clue, not as the final authority. A si…

Not always. Many mobile services use private addressing or carrier-grade NAT, which means the old habit of expecting inbound access on a public IP no longer tells the whole story. Some deployments use VPNs initiated from the remote router outwards, while others use managed remote-access methods that work around the lack of a public address. Comset generally looks at the end goal first: do you need a permanent site-to-site tunnel, occasional technician acc…

If the device count is only slightly above the router’s available ports, adding a switch is often the simplest answer. The main thing is to think about growth, power, physical layout and whether different types of devices should be kept logically separate. A router is there to manage connectivity and policy; it does not need to be forced into every local-network job. Comset can help decide whether a four-port router is enough on its own or whether the cle…

The safest answer is to use the router’s supported secure remote-access or VPN method rather than exposing open ports directly to the internet. The exact option depends on the router, the carrier constraints and the wider security policy, but the design should always be deliberate: authenticated access, clear user permissions and a manageable support process. Comset can usually steer the discussion towards secure remote access without turning the project …

Some applications handle failover quietly, while others may briefly reconnect or re-establish sessions. That is normal, because the public-facing IP path can change when traffic moves from the fixed service to the cellular network. The important thing is whether the interruption is acceptable for the business process and whether the design has been tested under live conditions. Comset’s role here is usually to match the failover design to the application.…

Yes, provided the router has the right local interfaces and the LAN has been designed sensibly. In a smaller installation a router may directly connect a few wired devices and a Wi-Fi access point. In a busier installation it may be better to let the router handle the WAN side while a switch and dedicated access point deal with the local network. Comset normally treats that as a local-network design question rather than a SIM question. The number of Ether…

That depends on the router’s failover rules and on how failure is detected. Some systems swap because the mobile connection drops outright. Others watch whether traffic can still reach a known destination, which is often more useful because a link can stay technically connected while being practically unusable. The transition may be quick, but the real question is whether the application can tolerate a short interruption while the router re-registers and r…

Yes, that is one of the most common use cases. The router watches the primary WAN connection and can switch traffic to the mobile service when the fixed link fails. The details matter, though: the failover trigger, the return-to-primary behaviour and the way services recover can all affect how seamless the experience feels to users. For a straightforward office backup, Comset will usually want to know what services must keep running, how many users are in…

Two different carriers usually provide the best redundancy, because the whole point of dual SIM is to reduce the chance that one carrier outage, congestion problem or coverage gap takes the site offline. Using two SIMs on the same network can still help with plan management or swap-over behaviour, but it does not give the same independence. Comset will normally ask which carriers work best on the site, whether the router is fixed or mobile, and how critic…

Absolutely. 4G is still the right answer for a large number of Australian deployments. It remains well suited to backup internet, remote monitoring, alarms, telemetry, light CCTV and everyday business connectivity where the application does not need cutting-edge speeds. In many places the most important factors are still Band 28 support, good antenna design, stable failover behaviour and sensible remote management. Comset’s 4G range is relevant precisely …

In practical terms, 4GX usually refers to support for carrier capabilities such as Band 28 and improved LTE performance, particularly on Australian networks where that band is widely used for broader coverage. For the customer, the takeaway is not the marketing label itself but whether the router supports the bands and LTE category that suit the local network and the expected use. Comset generally treats 4GX as part of the compatibility conversation. If a…

Usually the answer depends on the life of the project rather than on hype. If the application is just sending small sensor packets, meter readings or status alarms, 4G often does the job very well. Paying extra for 5G only makes sense if there is another requirement hiding in the background, such as future expansion, higher device density, a faster upstream need, lower latency, or a desire to standardise new deployments on a current-generation platform.
