The new pureLiFi Bridge XC Flex is revolutionizing home connectivity by delivering up to 1 Gbps of gigabit broadband internet directly through glass windows. Unveiled at Mobile World Congress 2026, this consumer-installable system uses invisible infrared light and wireless power transfer to eliminate the need for drilling holes or running complex cabling. By leveraging advanced LiFi data transmission, the hardware bridges the gap between outdoor network signals and indoor routers with unprecedented ease.
Designed specifically for homeowners, internet service providers (ISPs), and Fixed Wireless Access (FWA) operators, this technology solves a critical infrastructure bottleneck. High-frequency signals used for 5G, mmWave, and satellite communications notoriously struggle to penetrate building walls. The pureLiFi Bridge XC Flex allows users to bypass this physical barrier entirely, enabling high-speed connectivity that empowers remote workers, smart home enthusiasts, and enterprise users relying on robust outdoor-to-indoor network bridges.
The system architecture consists of an indoor unit and an outdoor unit that communicate seamlessly through the glass. The indoor unit connects directly to the mains power and standard networking gear, such as an Ethernet switch or a wireless router. It then wirelessly beams up to 25W of power alongside full-duplex, symmetrical data to the outdoor unit. This optical transmission is highly versatile, supporting single, double, and triple-glazed panes, as well as energy-efficient Low-E coatings that typically disrupt traditional wireless signals.
Installation and security are major focal points for the new hardware. Consumers can self-install the units in minutes using weather-proof Gecko tape, which features a high tolerance to misalignment. Because the system relies on directional infrared light rather than broad radio frequencies, it offers military-grade security. The interference-free connectivity is virtually immune to outside detection and jamming, making it an ideal solution for extending WiFi 7 and WiFi 8 signals outdoors for security cameras, backyard coverage, or enterprise hospitality events.
Transforming ISP Operations and FWA Deployment
For internet service providers, the pureLiFi Bridge XC Flex represents a massive reduction in operational overhead. Because the hardware is designed for simple self-installation, ISPs no longer need to dispatch engineers to customer homes to drill holes and route cables. This frictionless deployment model significantly lowers customer acquisition costs and accelerates network rollouts.
Furthermore, pureLiFi notes that optimal outdoor 5G Customer Premises Equipment (CPE) placement using this bridge allows FWA operators to serve up to six times more subscribers using their existing sub-6 GHz 5G network infrastructure. The efficiency gains are projected to be even greater for mmWave deployments, where line-of-sight and wall attenuation are the primary limiting factors. The system accepts any Ethernet input from CPE, including 4G, 5G, fibre ONTs, private 5G, and satellite connections.
At Mobile World Congress 2026, pureLiFi demonstrated the technology's versatility by showcasing it connected to 5G CPE hardware from industry partners Askey, Inseego, and Sonim. The company confirmed that the Bridge XC Flex will be available both as a standalone consumer system and as an embeddable module for CPE Original Equipment Manufacturers (OEMs) to integrate directly into future hardware.

Frequently Asked Questions
How does the pureLiFi Bridge XC Flex transmit data through solid glass?
The system uses LiFi technology, which relies on invisible infrared light to transmit high-speed data optically through the window panes, bypassing the need for radio frequencies that struggle with physical barriers.
Does the outdoor unit require a separate power cable or battery?
No. The indoor unit connects to your home's power supply and wirelessly transmits up to 25W of power through the glass to operate the outdoor unit.
Can I install the system myself, or do I need a technician?
The system is designed for consumer self-installation. It mounts to the window using weather-proof Gecko tape and features a high tolerance for misalignment, eliminating the need for professional ISP engineers.
My Take
The pureLiFi Bridge XC Flex is exactly the type of hardware innovation required to make mmWave 5G and high-frequency satellite internet truly viable for the mass market. The claim that FWA operators can serve up to six times more subscribers on existing sub-6 GHz infrastructure simply by optimizing outdoor CPE placement is staggering. By removing the 'truck roll'the costly process of sending a technician to drill through a customer's wallpureLiFi is solving the biggest logistical headache for ISPs today. As showcased with partners like Askey and Inseego at MWC 2026, the transition from standalone devices to embeddable OEM modules will likely make optical window bridging a standard feature for next-generation home internet setups.
