Global Bridge

What Global Bridge does

Global Bridge Co., Ltd. is a privately held wireless communication technology company headquartered in Incheon, South Korea, founded in January 2016 (originally as KMW Co., Ltd., rebranded in August 2017). The firm develops and commercializes Binary CDMA, a proprietary wireless protocol that combines CDMA and TDMA on unlicensed 2.4 GHz and 5.8 GHz ISM bands, originally developed by the Korea Electronics Technology Institute (KETI) in 2006 and transferred to Global Bridge. The technology was designated a Korean national core technology and is offered as the Guardian RF SoC for IoT integration, the Sky Bridge SB-100 and SB-200 wireless transceivers for video/audio/data transmission, and the Sky Link SL-100 repeater. Transmission speeds range from 300 Kbps to 60 Mbps, with ranges up to 7 km using repeaters and mobility support up to 130 km/h.

The product portfolio targets use cases including security and defense (CCTV surveillance, military communications), industrial and construction monitoring (tower cranes, harbor cranes, tunnels), IoT and smart devices (wearables, health monitoring), and environmental/infrastructure monitoring (wildfire, solar plants). Global Bridge sells primarily through direct enterprise sales in South Korea, with international reach initiated via an Amazon.com vendor membership, and holds ISO 9001, ISO 14001, and KC certifications plus Public Procurement Service registration that enables Korean government sales.

The firm's revenue model is not publicly disclosed. Only initial establishment capital of 250 million KRW is reported, supplemented by participation in the TIPS program and SparkLabs accelerator in 2018. No institutional investors, no parent company, and no named enterprise customers appear in the available sources. The company has 11-50 employees and has not disclosed revenue, making it a sub-scale, pre-commercial-scale hardware business whose commercial trajectory depends on converting its regulatory designations and patent portfolio into government and industrial procurement contracts.

Core offering

Global Bridge designs, develops, and manufactures wireless communication hardware and chipsets based on its proprietary Binary CDMA technology. Its product line includes the Guardian RF SoC for IoT applications and the Sky Bridge series of wireless transceivers (SB-100, SB-200) and repeaters (Sky Link SL-100) for secure, long-range transmission of video, audio, and data on free ISM band frequencies.

Product overview

Global Bridge offers a portfolio of wireless communication products centered on its proprietary Binary CDMA technology. The core offering includes the Guardian RF SoC (a hybrid integrated chip for IoT applications) and the Sky Bridge series (SB-100 and SB-200 wireless transceivers) for video, audio, and data transmission. The Sky Link SL-100 serves as a relay/repeater to extend range. The products share Binary CDMA as their underlying technology, combining CDMA and TDMA for secure, high-speed, long-range wireless communication with AES256 and ARIA256 encryption.

Partnerships

Two partnerships are on record, tiered core.

• BleckmanncoreStrategic or Co-development Partner · 20 April 2026Bleckmann, a fashion logistics provider, partnered with Global Bridge to offer smaller fashion brands streamlined access to international e-commerce marketplaces. This partnership removes traditional barriers such as legal complexities, IT integration, and logistical challenges for fashion brands looking to expand globally. Bright Swimwear is cited as a success case, successfully launching on five major US marketplaces including Nordstrom and Bloomingdale's within four months.
• KETI (Korea Electronics Technology Institute)coreTechnology or IntegrationKETI developed Binary CDMA technology as a national project in 2006 and transferred the technology to Global Bridge. The technology was designated as a national core technology. KETI conducted multiple technology transfers including wireless transmission technology, encryption basics, SoC optimization, and secure data transmission technology for wireless public services.

Broad incumbents

• Itron: Itron is a major AMI/smart-metering solutions provider with RF mesh and cellular connectivity for utilities. It directly overlaps with Global Bridge's stated AMI use case for the Guardian RF SoC but operates as a broad incumbent across metering hardware, software, and services.
• L3Harris Technologies: L3Harris is a major defense communications incumbent supplying tactical radios and secure wireless solutions. Comparable to Global Bridge's military/surveillance wireless focus but operating across a vastly broader defense portfolio.
• Landis+Gyr: Landis+Gyr is a global smart-metering and grid-management incumbent deploying AMI networks using RF mesh and cellular technologies. Comparable to Global Bridge's Guardian SoC AMI positioning but at vastly greater scale and breadth.
• Sensus (Xylem): Sensus, a Xylem brand, supplies AMI and smart-grid communications infrastructure including RF mesh networks to utilities — directly comparable to Global Bridge's Guardian AMI use case at utility scale.
• Ubiquiti Inc. Ubiquiti offers a broad portfolio of wireless networking equipment (airMAX, UniFi) for indoor/outdoor and enterprise deployments. It is a much larger incumbent competing for many of the same wireless backhaul and surveillance customers but lacks Global Bridge's proprietary CDMA security architecture.

Direct peers

• Silvus Technologies: Silvus Technologies develops secure, long-range mobile mesh radio systems for defense, public safety, and industrial markets — directly comparable to Global Bridge's Binary CDMA long-range, secure wireless mesh proposition. Both target mission-critical video and data transmission where standard Wi-Fi/Bluetooth are unsuitable.
• Cambium Networks: Cambium Networks manufactures fixed wireless broadband, point-to-point, and point-to-multipoint radios for industrial, utility, and surveillance customers. Comparable to Global Bridge's long-range (7km with repeaters) Sky Bridge transceiver line serving industrial and security use cases.
• Persistent Systems (MPU5): Persistent Systems builds the MPU5 mobile ad hoc networking (MANET) radio for military and high-mobility applications, matching Global Bridge's emphasis on secure, mobile (130 km/h) wireless video/data. Both are aimed at defense and high-speed-mobility communications.
• Rajant Corporation: Rajant provides mobile, peer-to-peer wireless mesh networks for mining, military, ports, and industrial IoT — the same vertical markets Global Bridge targets (harbors, construction, surveillance). Both deliver ad-hoc, infrastructure-free secure wireless connectivity for moving assets.

Emerging players

• Wirepas: Wirepas provides a mesh IoT connectivity stack for large-scale, low-power sensor networks targeting metering, lighting, and asset tracking. Comparable to Global Bridge's IoT/wide-area connectivity thesis but on a non-proprietary mesh architecture and with broader commercial deployment.
