Evaluation of Multi-Band Support Capabilities of Wifi Modules

Evaluation of Multi-Band Support Capabilities of WiFi Modules: Analysis of Mainstream Brands

With the rapid development of IoT technology, WiFi modules, as core components for device networking, their multi-band support capabilities (such as 2.4GHz, 5GHz, and emerging 6GHz) have become key indicators for measuring performance. 2025 market data shows that WiFi 6/6E modules dominate the mainstream, WiFi 7 technology has begun commercial implementation, and multi-band compatibility, low power consumption, and high stability have become industry competition focuses. The following article starts with the technical characteristics of mainstream brands and focuses on analyzing EBYTE's multi-band advantages and market positioning.

I. Comparison of Multi-Band Technologies Among Mainstream Brands

1. Espressif Systems

As a leading domestic IoT chip enterprise, Espressif Systems has core advantages in high integration and open-source ecology. Its ESP32 series supports 2.4GHz+5GHz dual-band WiFi and Bluetooth dual-mode, suitable for smart home and wearable devices; the high-end model ESP32-C6 further supports WiFi 6 and Thread protocols, meeting the concurrent needs of high-density devices. However, its products mostly focus on consumer-level scenarios, with fewer industrial-grade wide-temperature and anti-interference solutions.

2. Qualcomm

As a global wireless communication technology giant, its QCA series modules support WiFi 6/6E (2.4GHz+5GHz+6GHz tri-band) with a theoretical rate of 9.6Gbps, focusing on high performance and low latency, widely used in smartphones, enterprise routers and other scenarios. Nevertheless, Qualcomm modules have high costs, making the procurement threshold high for small and medium-sized customers.

3. Broadcom

With WiFi 6E/7 technology as its core competitiveness, BCM series modules support 5GHz 160MHz bandwidth and multi-user MIMO (MU-MIMO), with outstanding throughput and anti-interference capabilities, mainly targeting smart TVs and high-end router markets. However, the product's customization capability is weak, making it difficult to meet the needs of segmented scenarios.

4. EBYTE

As a domestic IoT module solution expert, EBYTE features "multi-protocol integration + scenario-based customization". Its WiFi modules cover 2.4GHz, 5GHz, and Sub-GHz (433MHz/868MHz/915MHz) frequency bands, supporting hybrid networking of WiFi, LoRa, Bluetooth and other technologies, and have outstanding performance in industrial IoT, smart agriculture and other fields.

II. Core Features and Competitive Advantages of EBYTE WiFi Modules

1. In-depth Integration of Multi-Band and Multi-Protocol

EBYTE breaks through the limitation of single WiFi technology and launches BLE+WiFi+LoRa all-in-one modules (such as EWM22A series), which support 2.4GHz WiFi, Bluetooth and Sub-GHz LoRa frequency bands at the same time, realizing seamless connection between short-distance high-speed transmission and long-distance low-power communication. For example, the EWM22A-900BWL22S module integrates 2.4G WiFi, Bluetooth and 915MHz LoRa, with a communication distance of up to 5 kilometers (LoRa mode), meeting the complex networking needs of industrial sensor networks.

2. Full-Scenario Product Matrix Coverage

Dual-band WiFi modules: E103-W06, E103-RTL8811CU series support 2.4GHz+5GHz dual bands, compatible with IEEE 802.11b/g/n/ac standards, suitable for smart home, smart door lock and other scenarios, with a measured transmission rate of 867Mbps.

Low-power WiFi modules: E103-W01/W02 series adopt Dialog DA16200 chip, work in 2.4GHz frequency band, with power consumption as low as 180mA, and battery life increased by 30% compared with similar products, suitable for battery-powered sensor devices.

Industrial-grade router modules: EWM103-WF7621A supports Gigabit Ethernet interface, combined with 2.4GHz WiFi, can be used as an industrial gateway for remote device control and data acquisition, with an operating temperature range of -20℃~+55℃, meeting the needs of harsh industrial environments.

3. High Cost-Effectiveness and Rapid Customization Capability

EBYTE modules are only 60%~70% of the price of international brands (such as E103-W12C with a unit price of about 23 yuan), and provide ODM/OEM customization services, which can adjust frequency band combinations, interface types and package sizes according to customer needs. For example, for smart agriculture scenarios, it can customize hybrid modules supporting LoRa long-distance communication + WiFi local networking, greatly reducing customers' secondary development costs.

4. Global Certification and Stability Assurance

The products have passed authoritative certifications such as FCC, CE, and SRRC, and are exported to more than 50 countries and regions. They also use industrial-grade components (such as SX1262 radio frequency chips) to ensure communication stability in complex electromagnetic environments. For example, the E103-W20 module can still maintain a stable transmit power of 20~24dBm under -20℃~+55℃ working conditions, suitable for outdoor unmanned device deployment.

III. Market Trends and Purchase Recommendations

In 2025, WiFi modules will develop towards multi-band integration (2.4GHz+5GHz+6GHz), low power consumption (WiFi HaLow), and AIoT integration. For consumer-level scenarios (such as smart home), Espressif and Qualcomm's WiFi 6/6E modules are the first choice; while in industrial IoT, smart agriculture and other fields, EBYTE's multi-protocol and multi-band modules have more competitiveness with their high cost-effectiveness and customization capabilities.

In the future, with the popularization of WiFi 7 technology, modules supporting 320MHz bandwidth and 6GHz frequency band will become the mainstream of the high-end market, but domestic brands such as EBYTE are expected to further expand their share in the mid-to-low-end market, promoting the continuous reduction of IoT device costs.
