Public Questions & Answers

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. C…

Yes, and that is often a sensible way to stage a project. Many businesses start by proving the application on 4G, then move selected sites to 5G if more speed, lower latency or higher capacity becomes worthwhile. The key is to avoid designing the installation in a way that makes the upgrade painful. Antenna type, cable choice, mounting positions, power supply and enclosure space should all be considered with the future in mind. Comset can help plan that p…

No. A 5G label does not magically create a stronger network. In metro or well-served areas a good 5G service can deliver higher throughput and lower latency, but in some regional locations the practical outcome is that the router spends most of its life on 4G fallback. The site survey, the local carrier and the antenna design still matter more than the sticker on the box. That is why Comset generally treats 5G as a deployment choice, not as a fashion acce…

Not every job needs the heaviest industrial platform, but many remote sheds and workshops do need something more robust than a domestic hotspot. The real questions are how reliable the connection must be, whether the unit will sit unattended, what temperature and dust levels are like, and whether the installation may need an external antenna or backup SIM. Once a router is expected to stay on all year, run cameras or monitoring devices, or survive a harshe…

The router is the brains of the connection. It holds the SIM, manages the network and provides the local interfaces such as Ethernet, Wi-Fi, VPN, serial or GPIO. The antenna is there to help the router hear and transmit the mobile signal more effectively. A weak connection can be caused by either side: the router may not suit the job, or the router may be fine but the antenna position, cable length or carrier choice may be wrong. That is why Comset normal…

Confirm that the exact model and accessories are available, current and suitable for the intended carrier. Recheck price, lead time, included power supply and antennas, firmware, warranty period, return conditions, restocking or inspection fees, shipping terms and who pays freight. Ask what technical support is included, whether configuration services are available and how discontinued products are handled. Policies and stock can change, and the scraped C…

A good starting point is to think about the problem rather than chase the biggest model. If the job is mainly failover for a home office, retail counter or small business, the right answer is usually a stable 4G or 5G router that can automatically step in when the fixed service drops, then hand traffic back when the NBN returns. The important questions are whether the site needs Wi-Fi, how many wired devices must be connected, whether voice services or EFT…
