Product Overview
Elevate your operations with the Uphone L553, the premier industrial 4G walkie-talkie and rugged PoC radio built for relentless environments. This IP68 dustproof waterproof Android radio survives 1.5m drops, submersion, and extreme temperatures, powering MT6762 octa-core performance with 4GB RAM/64GB ROM for seamless multitasking.
Certified to IP68 standards, it combines a powerful MT6762 Octa-core platform with 4GB RAM and 64GB ROM to run critical applications seamlessly. The 5.5-inch HD touchscreen, dual-SIM 4G connectivity, and high-resolution cameras are all powered by a massive 6550mAh battery, ensuring uninterrupted data capture and workflow efficiency where it matters most.
The 5.5-inch HD glove-compatible touchscreen (720x1440) ensures precise control during warehouse inventory management or construction site coordination, even with thick gloves or wet hands.
4G Push-to-Talk over Cellular (PoC) — Unlimited Range Communication
The L553 4G PoC radio supports Push-to-Talk over Cellular via 4G LTE full-network coverage (FDD-LTE and TDD-LTE), enabling instant one-to-one and one-to-many group voice dispatch over any distance where cellular coverage exists.
Built-in Barcode Scanner — 1D/2D/QR Code Capture
The dedicated scan head built into the L553 reads all major 1D linear barcodes and 2D matrix codes — Code 128, EAN-13, EAN-8, Code 39, UPC-A/E, Codabar, QR Code, PDF417, Data Matrix, Aztec — delivering fast decode response suitable for production-line scanning, warehouse receiving, outbound verification, and ticket validation workflows.
IP68 Rugged Design — Built for Harsh Environments
IP68 certification confirms the L553 is fully dustproof and waterproof to submersion depth — the highest common ingress protection standard for handheld field devices.
Large Touchscreen with Wet and Glove Touch Support
The multi-point capacitive touchscreen supports input from gloved hands and wet fingers — a non-negotiable requirement for workers in cold chain logistics, outdoor field service, food handling environments, and industrial cleaning contexts.
NFC — Identity Verification and Access Control
The onboard NFC reader (ISO 14443A/B, ISO 15693) enables contactless identity verification, access card reading, asset tag authentication, and attendance clock-in workflows at 13.56MHz.
Multi-System GPS Positioning
Built-in GPS/GLONASS/BDS satellite positioning provides real-time location data for fleet dispatch, asset tracking, delivery route verification, and geo-stamped audit trails.
High-Capacity Battery with All-Day Operation
The L553's large-capacity battery sustains full-shift operation covering both active PTT communication and scanning use

Application
The Uphone L553 is the right tool when your team's workflow includes both active voice coordination and barcode or NFC data capture — two requirements that historically forced operators to carry multiple devices.
Warehouse & Logistics Operations
Warehouse supervisors and logistics coordinators use the L553 to manage inbound receiving, pick-and-pack operations, and outbound loading in real time. An operator can scan a pallet barcode to confirm a shipment, then immediately PTT-broadcast a status update to the loading dock supervisor — without switching devices.
Security & Facility Management
Security patrol teams use the L553 as a combined radio and access control terminal. NFC card reading verifies personnel identity at checkpoints; the PTT function enables instant incident reporting to control rooms across large estates or multi-site operations. Real-time GPS allows dispatch to monitor patrol locations and respond to lone-worker emergencies.
Construction & Field Service
Construction site supervisors and field engineers use the L553 for PTT coordination across large sites where cellular-only coverage eliminates the repeater infrastructure burden of conventional radios. The barcode scanner enables tool tracking, material delivery verification, and inspection checklist barcode confirmation on-site.
Retail & Supply Chain
Retail operations managers deploy the L553 for store-to-warehouse voice coordination alongside shelf barcode scanning, delivery scanning, and NFC-based supplier documentation workflows. One device replaces a barcode scanner, a walkie-talkie, and — in some workflows — an NFC reader, reducing the total equipment investment per store associate and simplifying the device management overhead for IT teams.
Public Safety & Emergency Response
Emergency response coordinators and public safety teams use the L553's MCPTT-compatible PoC communication for incident command coordination, while the barcode and NFC functions support personnel identification, equipment tracking, and scene documentation workflows.
The Uphone L553 is engineered to empower professionals across diverse industries with cutting-edge technology, ensuring safety, efficiency, and accountability in various operations. Its robust design and advanced features make it an indispensable tool for the following sectors:
Designed for versatility, this device integrates seamlessly into workflows, delivering precision, durability, and intelligence to meet the demands of modern industrial and regulatory challenges.
Frequently Asked Questions
Q: What is the difference between the L553 and the L408/L502?
A:The L408 and L502 are primarily PoC communication radios — voice-first devices with touchscreen interfaces. The L553 adds a dedicated barcode scanner and NFC reader, making it the right choice when your team's workflow includes both active PTT communication and data capture tasks (scanning, inventory, NFC verification). If your team only needs voice communication, the L408 or L502 may be more cost-effective. If they need scanning without PTT, the L403 is better suited.
Q: Does the L553 work with Zello or other PoC apps?
A:Yes. As an Android device with full Google Mobile Services certification, the L553 runs Zello, Real-PTT, and other publicly available PoC applications. Enterprise PoC platforms accessible via APK are also compatible. For platform-specific certification questions, contact our technical team.
Q: What barcode types can the L553 scanner read?
A:The dedicated scan head reads all major 1D codes (Code 128, EAN-13, Code 39, UPC-A/E, Codabar, ITF) and 2D codes (QR Code, PDF417, Data Matrix, Aztec). Output is delivered as decoded text data directly to any text input field in your application, including WMS apps, spreadsheets, and custom logistics platforms.
Q: Is the L553 suitable for outdoor use in rain and dusty environments?
A:Yes. IP68 certification covers full dust ingress protection and continuous submersion — not merely splash resistance. The device is rated for outdoor use in heavy rain, washdown environments, and dusty industrial settings within the operating temperature range of -20°C to +55°C.
Q: Can the L553 work in cold storage environments?
A:Yes. The operating temperature range extends to -20°C, covering standard cold store environments. The touchscreen supports gloved-hand operation for cold chain workers who cannot remove gloves during scanning or communication tasks.
Q: What is the minimum order quantity for B2B customers?
A:MOQ depends on configuration and customization requirements. Contact our sales team with your fleet size and specification requirements for a formal quotation and sample arrangement.
Q: Is technical SDK access available for custom application development?
A:Yes. We provide SDK access for developers who need to integrate the barcode scanner, NFC reader, PTT hardware button, and GPS with custom enterprise applications. Contact our technical team to discuss your development requirements.
