Question 1

What is the difference between LoRa and LoRaWAN?

Accepted Answer

LoRa (Long Range) is the proprietary physical layer modulation technology developed by Semtech — it defines how RF signals are modulated over sub-GHz frequencies for long-range, low-power communication. LoRa modulation is implemented in Semtech's SX127x and SX126x ICs which are at the core of all LoRa modules. LoRaWAN is the open standard network protocol built on top of LoRa modulation, defined by the LoRa Alliance — it specifies the MAC layer, network architecture (star-of-stars), security (AES-128 encryption), device classes (A, B, C), and frequency plans for different regions (EU868, US915, AS923, etc.). A LoRa module (e.g. Semtech SX1276-based module) can be used in both LoRaWAN networks and in proprietary point-to-point LoRa links. LoRaWAN requires a LoRaWAN gateway and network server (either private or public — TTN, Chirpstack, AWS IoT Core for LoRaWAN). For custom point-to-point applications without infrastructure, LoRa P2P is simpler and does not require a gateway.

Question 2

What is a typical MOQ for wholesale wireless modules from China?

Accepted Answer

Standard WiFi/BT modules (e.g. Espressif ESP32-WROOM based): 100–500 pieces minimum for commodity catalogue modules; in bulk (10,000+), pricing drops significantly. LoRa modules (SX1276-based, e.g. HopeRF RFM95W, RAK4200): 50–200 pieces minimum. 4G LTE modules (Quectel EC21, EC25 series): 50–200 pieces minimum from distributors. NB-IoT modules (Quectel BC660K): 100–300 pieces. Zigbee modules (TI CC2530/CC2652-based): 100–500 pieces. For ODM/OEM customers integrating wireless modules into custom products, direct procurement from Quectel, Fibocom, or RAK Wireless at volume pricing starts from 1,000–5,000 pieces per model with dedicated FAE (Field Application Engineer) support.

Question 3

What is an FCC ID and why is it important for wireless module purchasing?

Accepted Answer

An FCC ID is a unique identifier assigned by the FCC to wireless radio devices that have been tested and authorised under FCC Part 15 (or Part 22/24/27 for cellular). For module buyers, the FCC ID matters because it enables a "modular approval" path for end products: if you integrate a pre-certified module (one with an FCC ID) into your product following the module's integration instructions, your end product may be exempt from full FCC testing for the radio functionality — you only need to declare the module's FCC ID in your product documentation. This significantly reduces certification cost and time-to-market. The FCC ID can be looked up at fcc.gov/oet/ea/fccid to verify the grant covers the intended operating frequencies and that the certification is current. When purchasing wireless modules for products destined for the US market, always confirm the module has a valid FCC ID covering your intended frequency bands and operating modes.
