pureLiFi Bridge XC Flex is a consumer-installable solution designed to be installed on windows (the ones made of glass, not Windows operating system!) in order to provide up to 1 Gbps broadband internet to the home.
The solution leverages LiFi data transmission using invisible infrared light combined with up to 25W wireless power transfer for fast, cost-effective broadband deployment that does not require any cabling. It is comprised of indoor and outdoor units compatible with a wide range of window types, including single, double, and triple-glazed panes, as well as energy-efficient Low-E coatings.
pureLiFi Bridge XC Flex highlights:
- Data Rates – Up to 1 Gbps, full-duplex, symmetrical
- Power – Up to 25W delivered from indoors to outdoors
- Installation – Self-install in minutes using weather-proof Gecko tape; high tolerance to misalignment
- CPE Compatibility – Accepts any Ethernet input from CPE: 4G/5G/mmWave FWA, fibre ONTs, private 5G, satellite, and more
- Security – Military-grade, interference-free connectivity, virtually immune to detection and jamming
High-frequency signals used for 5G and satellite communication do not penetrate walls very well, but the Bridge XC Flex outdoor unit does not have this issue. It is powered wirelessly from the indoor unit and supports bidirectional transfer through LiFi connectivity. The indoor unit is connected to the mains to power both units and to other networking gear, such as an Ethernet switch or a wireless router.
I can remember I had to wait a few years before switching from ADSL to FTTx broadband at home, because my house was too far from the Fiber distribution box, or I would have had to pay for cabling. This type of solution could have been convenient at the time. Beyond broadband Internet, the Bridge XC Flex can also be used to extend WiFi 7/8 signals from indoors to outdoors, for example, for security cameras or backyard connectivity, and hospitality, events, and transport hubs can also benefit.
It’s also beneficial to ISPs since they don’t need to send engineers to the home for installation, as the users can handle installation themselves. LiFi further adds that outdoor 5G CPE placement using Bridge XC allows FWA operators to serve up to 6x more subscribers with existing network infrastructure on sub-6 GHz 5G and has an even greater impact for mmWave deployments. While Bridge XC Flex will be provided as a standalone system, it is also available as an embeddable module for integration by CPE OEMs.
More details can be found in the press release. pureLiFi is also showcasing the Bridge XC Flex connected to 5G Consumer Premises Equipment (CPE) from Askey, Inseego, and Sonim, at Mobile World Congress 2026.

So if I understand things correctly, this is not “last mile” tech, or even “last few meters” tech, but really “last few cm, let’s get through a window” to get from an outdoors CPE which will receive 5G or whatever and get it into the building without drilling a hole in the wall or having to run cabling through existing entry points? On the photo and diagram there’s really nothing more than a bit of glass between the two units, it’s not like the indoor unit is talking to an outdoor unit meters away…
The use case seems quite limited to me. Of course avoiding drilling a hole in a wall is always a good thing, but:
The external CPE will probably need to get a decent mount anyway, and possibly some cabling from the outdoors pureLiFi unit to a good location for the CPE, so one is unlikely to avoid having to perform any works at allYou end up with this oh so nice pair of devices stuck on your window with cables dangling from each…Also many of the CPEs they talk about really aren’t designed for outdoor use.
Interesting tech, but weird application IMHO. Unless the range is much higher than just the thickness of the window (but the 25W power delivery makes me doubt it).
Yes, all this to avoid drilling a single hole.
If you’re in a rental and your landlord is going to give you trouble for drilling a hole then this might be your only option.
It’s niche but there’s business in niche even if it’s not for you. I just hope it’s not unreasonably priced. Given it’s basically a BiFi SFP and inductive charger, it’s hard to see that being too expensive.
Also virtually all new buildings have very good thermal insulation. Drilling a hole through it would compromise it. I am lucky to have a power outlet on the balcony, otherwise I could not have deployed my air monitor there.
The hole isn’t large, and is plugged up. Unless you live in Siberia, the impact is quite negligible.
You might not be aware, but it’s against regulation to penetrate the outer walls of many buildings and you will end up in trouble if you do so. But maybe you don’t mind getting fined?
Exactly this. In my renting contract I am explicitly forbidden to drill into the outer wall.
YOU might be.
A contractor who is insured and registered likely isn’t.
This is especially true when the install improves the value of the property.
If your landlord declines to let new service be installed by a professional, on your dollar, they are either incompetent or being malicious.
Literally untrue.
Stop confidently spreading falsehoods on the internet.
I would not be surprised if it were true in some European countries. My parents were not allowed to redo the “textured paint/roughcast” in their (older) house unless they also did the insulation to meet energy regulations for building, which would have cost much more.
So if somebody drills a hole in their wall, it might impact the energy rating of the house, although it’s probably unlikely for a small hole for a cable.
[ not that elegant, but there are also rj45 cables (flexible 0.2mm, ~0.25-0.5m length) for being adjusted to a window frame profile (maybe adding an adhesive stripe on top, showing ‘if there’s’ or ‘the amount of’ wear with opening/closing), not recommended, but PoE could be possible with up to ~300mA (@48V, ~12-15W)? (thx) ]
Waste of energy 🙁
The company claims it’s good for the environment 🙂
They don’t mention the energy wasted through RF power over time.
All windows are made of glass, no other recognition given to that word, even with a capital W.
Plastic?
Quartz?
Ice?
There are plenty of other materials.
