Semtech Wireless for IoT: A Procurement Manager’s FAQ on N93, Infinity Pro, and Why You Can’t Compare Them to a Klein Multimeter

What This FAQ Covers

If you’ve been tasked with sourcing Semtech products—especially wireless modules, LoRa chips, or the newer gateway solutions—you probably have a dozen questions. I manage purchasing for a mid-sized industrial IoT integrator (about 200 employees, three locations). Over the past 4 years, I’ve placed over 60 orders with Semtech distributors. Here are the questions that come up most often in my role, answered straight.

1. What is Semtech and why should I care as a procurement manager?

Semtech (officially Semtech Corporation, with a Canadian subsidiary—Semtech Canada Inc.) is the company behind the LoRa wireless technology that powers millions of IoT devices. They sell chips and modules (like the SX1276 transceiver), 5G/LTE routers (the XR60 series), and circuit protection components. For someone in procurement, the key takeaway: if your engineering team specifies LoRa, Semtech is often the only source for the core chip. That means sole-source negotiations, which changes your buying strategy.

I still kick myself for treating the first LoRa order like a commodity buy. If I’d researched lead times earlier, I could’ve avoided a 12-week delay.

2. Where does Semtech Canada Inc. fit into the supply chain?

Semtech Canada Inc. is the Canadian entity—often handles sales, support, and some R&D for the wireless division. If you’re ordering from a Canadian distributor (like Future Electronics or Avnet), your purchase order may route through Semtech Canada. The important thing: pricing and availability are the same as the US headquarters, but export compliance may vary. For example, N93 modules destined for certain regions might need a different license. I learned this the hard way when an order got stuck at customs.

3. What is the “N93” module and its typical applications?

The N93 is a specific LoRa module variant—I believe it’s the one with an integrated PA and lower noise figure for extended range. (Don’t quote me on the exact specs; I’m not an engineer.) We’ve used it in agricultural sensors and smart parking meters. In my experience, the N93 costs about 15% more than the standard SX1276 module, but the range improvement saves on gateway density. The numbers said go with the cheaper module. My gut said pay up for the N93. Turned out the longer range reduced our gateway count by 30%—net cost lower.

4. What is the Infinity Pro? How does it differ from the N93?

The Infinity Pro is not a module—it’s a LoRaWAN gateway from Semtech (part of their end-to-end solution line). It supports 8 channels, PoE, and has a built-in network server. I ordered 12 of them for a warehouse project last year. The N93 is an end-device module; the Infinity Pro is the infrastructure that receives N93’s signals. Different products, same ecosystem. If you’re comparing them directly, you’re mixing apples and base stations—which brings me to the next question.

5. Why do people search “Semtech vs Klein multimeter”?

Frankly, this comparison makes no sense technically. Klein makes multimeters and hand tools; Semtech makes wireless chips. But I get why it appears in searches: someone looking for “Infinity Pro” might confuse it with Fluke’s “Infinity” line, or a procurement person might be tasked with sourcing both a multimeter and a LoRa module on the same project. (I’ve seen it happen.) The real question is: should you compare them? No, because they’re not substitutes. But if you’re evaluating measurement equipment for IoT field testing, Klein multimeters are fine—just don’t expect them to transmit data over LoRa.

(Oh, and I should mention: the N93 has nothing to do with multimeters. That’s another common mix-up.)

6. How do I evaluate Semtech wireless solutions for my company?

Three things matter to me as a buyer:

• Lead time – Semtech modules can go 10–16 weeks. Always check with your distributor before quoting internal customers.
• Compliance – LoRa modules require FCC/CE certification. The N93 is pre-certified; the Infinity Pro gateway may need separate approval in some regions.
• Vendor support – Semtech Canada Inc. provides decent documentation, but their FAE response time varies. I keep a contact at the Canadian office—saved me twice when datasheets didn’t match production units.

There’s something satisfying about a smooth ramp-up. After the initial headaches, we now cut ordering time by 40% just by using a standard PO template with Semtech.

7. What’s changing in 2025 that I should know?

The industry is evolving: LoRaWAN now supports sub-GHz and 2.4 GHz bands, and Semtech is pushing higher integration. What was best practice in 2020 (buying separate chips and designing your own PCB) may not apply now—pre-certified modules like the N93 are faster to market. Also, Semtech’s acquisition of Sierra Wireless means they’re bundling cellular + LoRa. If you’re still comparing standalone modules to a Klein multimeter, you’re looking at the wrong toolbox. Embrace the change, but don’t ditch the fundamentals: always verify invoicing capabilities and lead time accuracy before signing a PO. That’s a lesson I learned the hard way in 2022, and it’s still true.
