As an avid MikroTik enthusiast and a telco RNO, I'd like to put my 2c here.
Good DL throughput is always welcome, so that's a no brainer. Here is what I think is severely lacking in the entire segment:
- Good DL throughput (mainly) comes from good RS SNR. Lower bands here are always welcome, e.g. 700MHz, 800MHz, etc.
- Good DL throughput can also come from higher order modulation schemes, i.e. 265QAM and hihger MIMO streams.
- LTE Carrier Aggregation in DL.
- Dual/Tripple-SIM with option for SIM "teaming". Often 1 or 2 operators can't reach a decent speed alone. When you have 2 (or more) SIM cards (even on different bands), acting as a single backhaul, redundancy and throughput are SIGNIFICANTLY improved. This one I personally believe to be the single most important feature that no consumer product in the segment has.
Or maybe a single hAP-like device with multiple USB ports that can support multiple USB modems in tandem? This of course scerams for 2 or more separate RF front-ends.
- With the increase of remote camera monitoring in the country rural areas, a severe demand for strong UL performace arises. Here are a couple of elegant solutions for this:
- LTE UL 2CA, i.e. LTE carrier aggregation in the UL. While not very common among telcos, it helps tremendously when there is a demand for higher UL throughput.
- multi-SIM in tandem (check above). Even more valid when the demand is in the UL.
- Fast USB port(s) for NAS solutions. It's always nice to have a remote seedbox.
- Maybe some "cloud" solution for cases where no prior VPN tunnel has been set, but you still need a remote management access. As you know, telcos are filtering inbound traffic to their SIM cards, so there is no way of "brute-forcing" a connection to SIM-only device w/o any prior tunnels in place.
- Ability to read most of the radio-related telco parameters. Together with OpenSignal and similar services, one can easily plan and verify their solutions, when one can read eCGI, PCI, RS CINR, allocated BW, etc.
- External antenna connectors is a MUST! Maybe even the next-gen ones, being used in commercial telco antennae.
- UV, IP and other environmental resistance in place.
- Support for 5G?
- Highest possible receive sensitivity.
- Highest possible transmit power, with low-loss coupling design.
- VoLTE support? It's always nice when you can place some calls while in the wilderness.
We have a 15GB/mo for 10,- EUR. We even have capped "all-you-can-eat" services for cheap, so building solutions around these dirt-cheap tariffs is only limited by current hardwire.
Of course stuff like PoE, security, reliability and robustness are in the must-have list. I can't imagine working with a brand where I have to travel huge distances just to power-cycle a hung device.
