Sierra Wireless vs Cisco in 2025: A Buyer's Story (EM7345, Software, and a USB Power Delivery Lesson)

How a One-Line Email Started a 45-Gateway Upgrade

It started with a one-line email from our ops director: “The routers in the vans are dying.”

That was January 2025. I'm the office administrator for a 180-person field services company, and for the past six years I've handled everything from office supplies to network gear. Our fleet of 38 work vans depends on LTE connectivity for dispatch, navigation, and job photos. When the router failure rate jumped, the internal complaints jumped with it. One technician put it simply: “If I have to reboot the modem in the middle of a highway again, I'm going to lose it.”

My job wasn't to pick the fastest 5G module or to win a spec-sheet contest. My job was to make the problem go away without breaking the budget or getting a phone call from finance.

The Question Everyone Asked: “Sierra Wireless vs Cisco?”

As soon as I started asking around, the first question from our IT guy was: “Sierra Wireless vs Cisco — which is better?” I understand why. Cisco has a strong reputation. I've specified Cisco switching for offices before, and it worked. But for vehicle-mounted gear, the question felt incomplete.

The search history in our own support portal told the real story: technicians were looking up terms like “sierra wireless em7345” to find replacement parts, and they didn't care about marketing. They needed something that would survive dust, heat, vibration, and the occasional driver who treats electrical panels like coat hooks.

So I did what a buyer does: I created a shortlist and asked for quotes.

The First Quote: Cisco

The Cisco quote arrived from a regional reseller. The hardware price was competitive. Then there were line items that made me squint:

• Security software subscription — annual (not optional)
• Advanced support tier — labeled “recommended”
• Deployment services — a flat fee with no description
• RMA shipping — invoiced separately

None of these were hidden, exactly. But they weren't prominent either. I had to call the reseller to decipher the total cost of ownership. That took three days of email and one phone call that got mysteriously dropped. To be fair, the reseller was not trying to rip me off. The line items were real. But the process was not what I'd call transparent.

The Sierra Wireless Quote: Different in a Welcome Way

Meanwhile, a Sierra Wireless distributor sent a much shorter quote. It listed the hardware, a separate line for Sierra Wireless software for remote management, and one line for freight. No surprise “advisory” fees. No “you'll need this later” service package. I remember thinking, “This looks too simple. What am I missing?”

And I was missing something. The Sierra Wireless software subscription was optional, but I didn't know if we needed it. I called the distributor's presales line. They explained that for fleet visibility, the software would save us from sending technicians to the field for every settings change. I asked for a demo. They scheduled one within two days. That alone felt like a different world.

The EM7345 Question and a Lesson in Product Lifecycles

Our existing fleet devices were built around the Sierra Wireless EM7345 module. According to Sierra Wireless's product documentation (sierrawireless.com) as of early 2025, the EM7345 is an LTE-Advanced Category 4 module with peak downlink speeds of 150 Mbps and uplink of 50 Mbps. The distributor told me it's a mature design. I don't have hard data on its long-term supply. My sense is that vendors prefer to steer you toward newer lines. I liked that the distributor said so instead of letting me discover it later.

From a buyer's perspective, the “best” module is the one you can actually get. We decided to stick with the EM7345-based gateway for replacement consistency. The interns could swap a broken unit without re-training. There were a few “but what about 5G?” questions from our field IT manager, but he agreed that our current applications didn't need more bandwidth.

The USB Power Delivery Surprise: While Recording the List of What's Connected

Here's where the story takes a turn.

Our technicians plug a lot of stuff into these routers: a tablet, a mobile printer, a dashcam, sometimes a diagnostic laptop. Many of those devices charge over USB-C. In the past, the old routers' USB ports simply couldn't keep up. When a tablet was running the job list and recording in the background, the charger would either drop the connection or the tablet would fall behind on battery.

So I asked the distributor for a loaner unit to test before signing off. Our IT coordinator, Mark, spent an afternoon in the parking lot with the gateway and a handful of devices. Halfway through the test, he opened a support ticket that, I will never forget, read:

“USB power delivery while recording list of connected devices causes the USB port to reset. Consistent. Reproducible.”

At first, I felt that familiar dropping feeling in my stomach: another vendor problem. But Mark added a second note:

“Support replies within 20 minutes. They have a firmware update. They want to walk through it live.”

That was the turning point. Sierra Wireless software allowed Mark to update the gateway remotely and capture a new power-delivery log while running the same test. The fix worked. The USB-C port stayed on while the app recorded list updates over LTE.

I later learned that power delivery over USB-C follows the USB Power Delivery specification, and that older peripheral behavior can be finicky when you mix devices. Per the USB Implementers Forum (usb.org), USB PD 3.1 supports up to 240 watts, but the negotiation is not always smooth in mixed-vendor setups. I don't have hard data on how many fleets hit this, but I can tell you this test saved us from a very bad rollout.

How the Deployment Went

We ordered 45 gateways with EM7345 modules, a three-year Sierra Wireless software subscription, and a spare-pool contract for replacement units. Total spend: around $78,000, including spare units and support.

That number is worth a pause. The Cisco quote, without the add-ons, looked about 9% cheaper. But when I factored in the optional subscriptions and the deployment assistance that the reseller said would “definitely be useful,” the gap nearly disappeared. In my experience, the quote that lists everything upfront is the one that costs less in the end. This is the transparency principle I've learned the hard way. (Not that I'm perfect — I once ordered a $12,000 software license because a salesperson said “additional onboarding is included,” and the invoice later told me otherwise.)

Deployment itself was surprisingly smooth. Here's what actually happened:

1. Week 1: Mark staged one gateway in his lab, updated firmware using Sierra Wireless management software, and re-ran the USB power delivery test.
2. Week 2: We installed gateways in 10 vans. One unit had a bad power harness. The distributor overnighted a replacement, no restocking fee.
3. Week 3: The remaining 28 vans were done by our own technicians, using a checklist Mark wrote. The old routers were returned for credit.

Now, two months in, the “I'm stuck on the highway with no signal” calls have basically disappeared. The ops director thinks I'm a hero. Finance is happy because the invoice matched the quote to the cent. That is rare enough to mention.

What I'd Do Differently (and What I'd Tell Another Buyer)

Looking back, I should have requested a hardware sample before getting quotes. At the time, I thought a module is a module, and the spec sheet would be enough. It wasn't the EM7345's LTE performance that concerned us; it was the USB-C quirks around it. If I could redo that decision, I would ask for a test unit in the very first meeting. But given what I knew then, our process was reasonable.

If you're trying to decide between sierra-wireless and Cisco for a 2025 fleet upgrade, here's what I'd tell you:

• Don't start with brands. Start with the devices your team actually uses. The best router on paper is useless if it drops power to the tablet running your job list.
• Ask for the “what's NOT included” list. Every vendor has one. The good ones send it without being asked.
• Test with your real equipment. USB power delivery issues don't show up in a three-minute sparkle demo. They show up when a Bluetooth barcode scanner is connected and the recording app is running.
• Check the software before you buy. Sierra Wireless software isn't a nice-to-have for fleets; it's how you'll update 38 devices without a road trip.

I don't have a crystal-clear answer on whether Sierra Wireless is better for your organization than Cisco. The accurate answer is: it depends on your workflow, your support tolerance, and your patience for line-item surprises. But I can say this: the vendor who showed me the full price on day one earned my trust. The vendor who made me chase the total cost did not.

That lesson is worth more than the modem's maximum download speed.
