BreadCrumb® ME4

Rajant BreadCrumb ME4 — Portable Dual-Band Mesh Node for High-Performance Networks in UAE Build resilient, high-capacity wireless mesh networks with the Rajant BreadCrumb ME4 — a rugged, portable node equipped with two radios and antenna ports, supporting multiple frequency bands and industry-grade security. Ideal for Dubai and the UAE’s demanding deployments — from infrastructure corridors and surveillance backhaul to mobile, temporary, or hybrid networks. Key Features & Benefits BreadCrumb ME4 Dual Transceivers & Flexible Configurations ME4 supports multiple configurations combining 900 MHz, 2.4 GHz, 4.9 GHz, and 5 GHz radios. This gives you options to balance coverage, interference, and throughput based on your deployment needs. High-Performance MIMO & Antenna Diversity With 2×2 MIMO for most radio bands, ME4 maximizes capacity, mitigates multipath effects, and delivers more stable links. Rugged & Weather-Sealed Design Built to withstand harsh environments, ME4 features a rugged, sealed chassis that protects against dust, moisture, and extreme temperatures. Alliance Corporation Integrated Wi-Fi & Ethernet Bridging BreadCrumb ME4 includes built-in Wi-Fi access point functionality plus multiple Ethernet ports. Ideal for bridging wired and wireless segments, connecting client devices, sensors, or video systems. Adaptive Networking with InstaMesh® The ME4 leverages Rajant’s patented InstaMesh protocol that dynamically routes traffic in a self-healing mesh. As nodes move or fail, network connectivity is preserved. Advanced Security & Encryption Options Offers a wide suite of cryptographic options including AES-256 (GCM/CTR), MAC address encryption, per-hop and per-packet authentication, and support for suite B algorithms. Power & Efficiency Operates from 8–48 VDC, with ~5.5 W typical (idle) consumption and up to ~19 W peak at 24 V depending on radio mix. Scalability & Clustering Supports mesh clustering so that groups of ME4 nodes can mesh internally and avoid interfering with other parts of the network. This enables efficient segmentation in complex deployments. Specification Value / Range Frequency Bands 900 MHz, 2.4 GHz, 4.9 GHz, 5 GHz (various combinations) ( Alliance Corporation ) Data Rates Up to 300 Mbps (device dependent) ( Alliance Corporation ) Transmit Power Up to ~30 dBm for some bands (region dependent) Receive Sensitivity –96 dBm to –73 dBm typical (varies by band) Interfaces Gigabit Ethernet + 10/100 Ethernet, USB for firmware/GPS Physical Size 189 × 95 × 51 mm Weight ~1,162 g (varies by configuration) Operating Temperature –20 °C to +80 °C (some variants) Power Input & Consumption 8–48 VDC, ~5.5 W idle, ~19 W peak Certifications & Compliance FCC, IC, CE, AS/NZS, UAE TRA (some models) Why BreadCrumb ME4 Suits Dubai & UAE Deployments Flexible band options Portable Dual-Band Mesh allows you to align with TDRA spectrum rules and avoid spectrum congestion in dense city areas. Mesh clustering helps segment networks in large complexes, campuses, or infrastructure corridors. Robust build makes it trustworthy in hot, dusty, humid, or coastal zones across the UAE. Integrated bridging & Wi-Fi support devices without needing extra hardware — ideal where wiring is difficult. Scalable architecture : ME4 pairs well with higher-tier Rajant nodes (LX5, Hawk) to build full coverage systems. FAQ Suggestions (for Rich Snippets / AI) Q: Can ME4 operate on 900 MHz as well as 2.4 or 5 GHz? A: Yes. Some ME4 models include a 900 MHz transceiver paired with 2.4 GHz, 4.9 GHz or 5 GHz radio to extend range or penetrate difficult links. Q: What is mesh clustering in ME4? A: Mesh clustering restricts certain ME4 nodes to only communicate among themselves on specified channels. This reduces interference and enables mixed PTP/mesh configurations. Q: How secure is communication through ME4? A: Very secure. ME4 supports a broad set of encryption methods including AES-256, per-hop/per-packet authentication, and MAC address encryption to protect your data. Q: What power inputs are supported? A: ME4 accepts 8–48 VDC input, with passive PoE support. Idle consumption is ~5.5 W, with peak usage up to ~19 W depending on radio configuration.
