In the wave of industrial IoT and intelligent automation, the challenge of simultaneously delivering long-distance HD video transmission and highly reliable data communication has long been a pain point for the industry. The E611-868NW33S and E611-915NW33S wireless modules from Chengdu Ebyte Electronic Technology Co., Ltd. are purpose-built to solve this exact challenge.

Product Overview : One Module, Two Core Needs

The E611-868/915NW33S is Ebyte's 2W high-power, long-distance video + data integrated wireless module. It seamlessly fuses video transmission and data communication, designed for complex scenarios that demand both HD video streaming and real-time control data.

• Core Positioning: Long range, high bandwidth, multi-node, integrated video + data

• Perfect Replacement: For traditional long-distance wired connections, complex cabling, and multi-device stacking solutions

• In a Nutshell: The ultimate wireless tool for those who need it all — distance, speed, and scale

Core Advantages: Three Breakthroughs Reshaping Connectivity

1. Burst Throughput: 16Mbps + 4 Channels of 1080p

Traditional data-only modules lack the bandwidth for real-time HD video. The E611 series delivers a peak data rate of 16Mbps, supporting simultaneous transmission of up to 4 channels of 1080p HD video — whether for drone aerial photography, industrial inspection, or remote surveillance.

• Receiving Sensitivity: -107dBm @1M MCS10, ensuring stable reception of weak signals

• Rich Interfaces: UART + PHY (Ethernet) interfaces, compatible with a wide range of host devices

2. Long-Distance Coverage: 2km Ideal Range

With a powerful 33dBm (2W) RF output (antenna gain 5dBi, at 16Mbps data rate), the module achieves an ideal transmission distance of up to 2km in open, clear environments. This performance easily covers large campuses, farms, construction sites, or complex terrains.

• Wide Voltage Input: Supports 4.25V~28V; ≥12V recommended for full 2W output

• Industrial-Grade Protection: Built-in ESD protection and power surge suppression for harsh environments

3. Flexible Networking: 31 Slave Nodes + One-Key Pairing

The E611 series supports an efficient star network topology, with one master connecting up to 31 slave nodes. The one-key pairing feature — triggered via the PA9 pin in approximately 2 seconds — simplifies master-slave mode switching and dramatically reduces deployment complexity.

• Simultaneous Ethernet + Serial Transparent Transmission: Both network and serial devices connect wirelessly

• Relay Networking: Supports APSTA relay mode for multi-hop range extension

• Universal AT Commands: Flexible configuration of operating mode, SSID, frequency, bandwidth, encryption, etc.

 Who Needs It? Four Typical Use Cases

Technical Specifications

Quick Start in 3 Steps

1. Hardware Connection: Connect antenna, power at 12V, connect Ethernet to PC or UART to host MCU

2. One-Key Pairing: Hold the PA9 pin for ~2 seconds — the Link and RSSI LEDs will stay solid, indicating successful pairing

3. Data Transparent Transmission: Open a serial terminal or network debugging tool to start sending and receiving data

FAQ

Q1: What's the difference between E611-868NW33S and E611-915NW33S?
A: Their hardware specifications are identical. The only difference is the operating frequency band: 868NW33S operates at 863~873 MHz (EU/ETSI standard), while 915NW33S operates at 902~928 MHz (NA/FCC standard). Choose based on your target market's radio regulations.

Q2: Can it really reach 2km in practice?
A: 2km is the ideal range tested in open, clear environments (5dBi antenna, 16Mbps data rate). Actual range depends on antenna type/gain, installation height, obstacles, and electromagnetic interference. For non-line-of-sight (NLOS) or obstructed scenarios, range will decrease — relay networking is recommended to extend coverage.

Q3: What are the power supply requirements?
A: The module supports 4.25V~28V wide input. However, a supply of ≥12V is required for full 33dBm (2W) output. If powered below 12V, TX power will be reduced, and transmission distance will shorten accordingly.

Q4: How many slave nodes can one master connect?
A: In star topology, one master supports up to 31 slave nodes. For wider coverage, enable relay networking (APSTA mode) for multi-hop range extension.

Q5: Can video and data be transmitted simultaneously?
A: Yes. The module supports simultaneous Ethernet + Serial transparent transmission — video streams via Ethernet (PHY) and control/sensor data via UART, without mutual interference.

Q6: Is configuration difficult? Do I need programming skills?
A: Not at all. The one-key pairing feature allows master-slave pairing in ~2 seconds by holding the PA9 pin. Advanced parameters can be configured via universal AT commands or Ethernet interface for flexible settings like frequency, bandwidth, encryption, etc.

Q7: Can the module operate in harsh outdoor environments?
A: Yes. The module features built-in ESD protection, power surge suppression, and industrial-grade component selection, making it suitable for industrial environments with electromagnetic interference and temperature variations.

Q8: What advantages do 868/915MHz bands have over 2.4GHz?
A: Sub-1GHz bands (868/915MHz) offer better penetration and longer range than 2.4GHz, which is heavily congested by WiFi, Bluetooth, and ZigBee. This results in more stable and reliable communication.

In the field of long-distance wireless communication, the E611-868/915NW33S is not a collection of buzzwords — it is a precise answer to real industrial needs. With high power, high bandwidth, and multi-node capability, it truly solves the industry bottleneck of "you can't have both range and speed."

If you are struggling with long-distance video surveillance, complex industrial networking, or UAV video transmission, this module is the solution you've been searching for. It makes long-distance wireless connectivity simpler, more stable, and more powerful than ever before.
