Cell Modem Recommendations

The n71 is the 5G band of the T-Mobile's 600Mhz spectrum. That means I'd have to get a 5G cell modem. The lowest I've seen them is about 400USD. That's a too steep of a price for me for a backup modem

But I didn't think about USB over Ethernet. That is be an option I didn't think of... IF the device has pfsense USB support. That's a big IF.

I thought you were looking for 5G. As I mentioned, if you only need this occasionally, then perhaps you can just use your cell phone.

BTW, GSM is dead, at least in much of the world and 3G isn't far behind.
You may want 4G, if not 5G. Also, compared to even 3G, the bandwidth with GSM is pathetic.

As for the Ethernet adapter, those run from about $15, so it won't be too expensive of an experiment.

I have seen over 500 Mb/s on 5G with my phone. In my area, 600 MHz is used, along with, IIRC, 2600. However, C band n77/78 is in the works and I expect 1900 will be used soon too, as 2G and 3G have been shut down there. My carrier uses something called Dynamic Spectrum Sharing, which allows 4G & 5G to share a band, so I may be seeing something there too.

I'm looking for 4G/LTE, Not 3G. Also, Google Fi's data-only sims only use the T-Mobile network. The 600MHz range isn't even available less than 4G in the US.

I'm not looking for big bandwidth. I'm only looking to keep VOIP and Instant Messaging programs working so my family can contact me while I'm away from the house. Also, keeping it so I can call my ISP and yell at them to fix things. 4G is fine for that.

I thought you said 5G:
"Must support LTE 71 Band (GSM) and or 5G n71 Band"

I only mentioned 3G in comparison with GSM (2G) which is not what you're looking for, even though you said you were.

Yeah, 5G modems may be scarce, but plenty of phones support it. Also, I doubt there ever was GSM on n71, as that's a new 5G band. In North America, GSM & 3G were on 850 and 1900 MHz. On Rogers, my carrier, GSM is long gone, as is 3G on 1900. 3G will be on 850 for another couple of years, as a lot of things still depend on it. So, around here, almost all the bands will be 4G, 5G or both.

Here's some T-Mobile info.

Not in the US.

Band 71 is 4G/LTE.
Band n71 is 5G.

My phone connects via it all the time, well the last 2 weeks when it finally rolled out here, in both modes.

Look at Wireless Haven they have LTE modems and whole community on what it takes to get them dialed in just right.

hydrian

Looking at this as 5G price point.

Just gotta figure out how to get tasker to start tethering on boot.

From LTE frequency bands:
71 FDD 600 Digital Dividend (US) 663 – 698 617 – 652 −46 5, 10, 15, 20

From 5G NR frequency bands:
n71 FDD 600 Digital Dividend (US) 663 – 698 617 – 652 −46 5, 10, 15, 20, 25[B 1], 30[B 1], 35[B 1] [B 8]

Looks to me like LTE (4G) 71 and 5G n71 are the same thing. Carriers can put whatever they want on their channels. These days, it's 4G & 5G and 2G & 3G are going away, if not already gone. This means your choices are 4G or 5G. According to that T-Mobile link I provided, they have both on 600 MHz. You said you don't want to pay the cost of a 5G modem, so that leaves 4G. Also, I suggested that if you only need it occasionally, a cell phone may be adequate and even provided a method that could be used to get Ethernet from a phone.

Hi together,

get a refurbed 5 G smartphone that is supporting this
SIM card and band, inserting your SIM card and connect
it to the USB port of the pfSense. And now you make
this usb port being a second wan port and create
failover rules. This is the cheapest and
fastest way as I would try it out.

More expensive the you found it but better running
cause of the eth port of the device;

RaspBerry PI with 5G modem that supports your band
~200 € without modem and ~550 € with modem
RaPi Kit

Two other options around $350 can be that boxes here
but also not far away from your ~$400 ish seen solution.

@dobby_

I'm looking at an unlocked 5G android phone that I can root. I'm going to have root to automate the USB tethering. I don't want to have to touch the phone because the tethering disconnected everytime the cell signal cuts out , the phone reboots, or I reboot my pfsense box. So my price point is $225USD for 5G and $140USD for LTE.

I love the idea of the RaspBerry PI with 5G modem, but that's a bit too $$$ for me.

hydrian

Does anybody know of a T-Mobile 5G(Band 71) cell phone that will auto-tether at boot for less than 210USD?

I know I have to set Developers Tool -> Default USB Mode to Tethering. Is that all that is needed?

A Former User

@hydrian

The fastest and/or easiest way to realize it would be the
5G smartphone on USB. But pfSense will be reassigning
the WAN even new if you reboot, for sure I consider to
that.

I would prefer to look for something like the RaspBerry PI because it will be the only one that comes with a real
rj45 port to connect to the pfSense as second wan port.

hydrian

As much as I want to go to 5G, I think I need to stick with LTE with my budget. The big thing, is I need no interaction once set up. Probably, going to get a Netgear LB-1200 in bridge mode and inject passive PoE to it, and be done with it.

Thanks for all the recommendations though.

LANTRONIX G520 https://www.lantronix.com/products/g520/)

And remember: there are not “cheap&quality” combination in wireless technologies. You get is what a You pay for.
Another one suggestion: better to buy products from companies that made for finance, energy, medical, and other “mission critical” grade systems. The quality of device (stability of work, software quality, manufacturing,...) in this case MUCH MORE BETTER than ZTE, Zyxel, Netgear, Microtik, etc., etc...

But there are small “hint” here: You may find on eBay.com some Enterprise quality for reasonable cost, for example PremierWave (previous model)... :) I able to see PremierWave right on Your budget (https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2047675.m570.l1313&_nkw=PremierWave&_sacat=0).

None of the iRZ and Microtik products support band 71/n71, a requirement to get signal in my area. The Band 71 rollout are sort of new to the US so the older/used products will not have support for them. The LANTRONICS are way out of my price range.

I've basically decided I'm only going to get a 4G/LTE modem because the cost for 5G Cell modem card is just out of my budget.

@hydrian I'm using the Netgear Nighthawk M5. It does support n71 and it supports T-Mobile. It is NOT cheap though.

hydrian

@robh-0 Yea, I've looked at it. Way out of price range.

At this point, for 4G, I'm looking at the Netgear LM-1200. It is about 140 USD new.

The upper end of my budget is about 300 USD. Most usable 5G deployments are about 400. The only way I can get 5G into that budget is with a tether 5G cell phone. The big issue with tethering is reliability. I can't have any interaction from myself with common functions. I need it stable over reboots.

@hydrian I tried a 1200. The 1200 only has a CAT6 modem, so you will only get about 35mbps, tops. I swapped the SIM into the M5, which has a CAT16 radio, and now I get up to 90mbps on 4g.

I work from home, so having fast speeds and 100% uptime is important to me. I'm paying $119 a month for the unlimited AT&T SIM, and on top of that I have a WISP connection that's only 15/5 that I pay another $85 a month for. I live out in the boonies, so these are my only options. I also travel a lot, so it's convenient to grab the M5 and go, letting pfSense fail over to the WISP while I'm gone.

@robh-0
I'm not that bad out in the sticks. I have a decently stable cable 450Mb/20Mb internet connection for most of my work. The problem I have is that if that connection goes down, we lose ALL electronic communication in and out of our house, other than AM/FM radio. The "hard-wired" phones are really still VOIP and don't use the old POTS lines. Neighbors complain about them quite often going down. So I can't trust them.

Luckily, most cable internet outages are only a few hours at most. We've had an 8 hour outage before, but that was only once in 3 years. The big issue are storms breaking the 'last mile' of our cable connection. Also, with inclement weather, there are more reason to need communications.

I need a cell modem that I can attach a good antenna on to get a stable, but not great, Band 71 connection. That way I can still have communication with the house in the case of a cable outage. Typical outage are about once every 3 months for few hours. Paying a large sum per a month, doesn't make a lot of sense for mostly passive connection.

This is why I'm setting up Google Fi data-sim only for this device. Yea, it is 10USD/GB of bandwidth, but not having the per month charge is a big savings for something I will be rarely using.
