But treatments applied to glass to help insulate homes as part of energy-efficiency initiatives impact the permeability of radio signals.<\/p>\n
Professor George explained such treatments reduce the strength of radio signals passing through glass, \u201can advantage if someone was trying to tap into your Wi-Fi from outside\u201d by weakening the signal and affecting its use.<\/p>\n
The flip side, though, is the signal penetrating from outside to inside is also weakened, impacting user experience.<\/p>\n
It is a problem which becomes more pronounced with higher frequencies, meaning 5G is particularly hard hit, but there are ways to punch through the pane.<\/p>\n
Here are three possibilities.<\/p>\n
Frickin lasers<\/strong> Siemens stated its windows \u201cconduct signal power that is 50-times stronger than standard glass\u201d, with a system currently in use by the Austrian rail company delivering a 33 per cent increase in the \u201cavailable time of good 4G reception\u201d.<\/p>\n The windows supplied \u201chave a special laser-beamed structure\u201d which is \u201cscarcely detectable by passengers\u201d.<\/p>\n A Siemens representative said the structure is \u201csimilar to classic\u201d antennas, but with the option to \u201cdefine both a relatively wide passband and a blocking band\u201d.<\/p>\n The patented technology does not require a different approach to manufacturing the glass itself, just the inclusion of a \u201cfine geometric pattern\u201d comprised of very narrow metal-free lines created in a conductive layer.<\/p>\n Siemens\u2019 approach works with a spectrum range of around 400MHz to 3.7GHz, with frequencies above 5GHz blocked.<\/p>\n It provides another customisation point for Siemens when pitching for contracts, being \u201coffered to customers whenever they have special requirements for mobile phone reception\u201d inside vehicles, the representative said.<\/p>\n Big in Japan<\/strong> The operator\u2019s goal is to boost signal penetration while \u201cmaintaining the insulation benefits of windows\u201d for homes and offices.<\/p>\n It stated aerogel offers high-performance thermal insulation, but with \u201ca dielectric constant close to that of air\u201d, which makes it easier for radio waves to penetrate.<\/p>\n The companies have been somewhat coy about the progress of their tests, though the process is likely highly complex given Docomo is targeting millimetre- and terahertz-wave frequencies for 5G and, ultimately 6G technologies.<\/p>\n Seeing the light<\/strong> Light Fidelity (Li-Fi) specialist pureLiFi unveiled LINXC Bridge at MWC Barcelona 2024, a system developed with Canada-based Solace Power which the pair stated has a particular eye on mmWave 5G.<\/p>\n LINXC Bridge uses pucks installed on the window frame to beam signals indoors using light rather than radio and is being pitched as a way to deliver fixed wireless access (FWA) services.<\/p>\n A pureLiFi representative told MWL<\/em> the set-up captures 5G signals outdoors \u201cwhere they are strongest\u201d and not \u201csubject to attenuation by walls and windows\u201d which are \u201cincreasingly impermeable to 5G signals, especially mmWave\u201d.<\/p>\n The representative noted \u201ceven single pane clear glass can block mmWave signals to a greater degree\u201d than materials including concrete or wood, explaining insulating materials are often \u201cmade from thin layers of silver\u201d which, like any metal, blocks radio waves.<\/p>\n LINXC Bridge taps pureLiFi\u2019s speciality by turning \u201ca broadband internet signal into light to pass through the window in both directions\u201d and then converting it \u201cto an Ethernet signal for connection to the local area network\u201d or customer premises equipment (CPE).<\/p>\n The representative highlighted power consumption, signal strength and installation cost benefits compared with \u201ctrying to force 5G through a window that wants to block it\u201d.<\/p>\n In its launch statement, pureLiFi noted the system can be installed by users \u201celiminating the need for costly professional installation\u201d and \u201cshortening time to market for network operators\u201d.<\/p>\n Its representative added the system \u201calso transfers power wirelessly through the window\u201d.<\/p>\n Although pureLiFi is pitching LINXC Bridge on its 5G capabilities, the representative said the system is technology agnostic: \u201cWhatever the signal is, we can convert back and forth to\/from light for transmission through the window\u201d.<\/p>\n The company is in \u201cadvanced discussions with global operators\u201d about using the set-up in their FWA services, with tests underway \u201cwith an eye to large-scale consumer field trials later this year\u201d.<\/p>\n LINXC Bridge is also gaining traction with \u201cmultiple\u201d CPE vendors with a slant towards 5G and mmWave. These companies are either looking at producing pucks or integrating the set-up into their own routers or modems.<\/p>\n The post Feature: How radio signals can penetrate the heart of glass<\/a> appeared first on Mobile World Live<\/a>.<\/p>\n\n \u7acb\u523b\u8a3b\u518a\u53ca\u5831\u540d\u96fb\u8166\u88dc\u7fd2\u8ab2\u7a0b\u5427!

The carriages in the 19 trains to be supplied to Austrian Federal Railways will use a Siemens-developed technology to limit the frequency loss for mobile signals passing through the windows, in turn significantly boosting it.<\/p>\n![\"Interior](\"https:\/\/assets.mobileworldlive.com\/wp-content\/uploads\/2024\/04\/22142126\/Siemens_Radio_Permeable_Glass.jpg\")

Early in 2023, NTT Docomo embarked on a process to combat the thermal coating issue, teaming with specialist company YKK AP to evaluate aerogel, which it described in a statement as a \u201clight, porous material\u201d.<\/p>\n
A third possibility involves using light.<\/p>\n![\"A](\"https:\/\/assets.mobileworldlive.com\/wp-content\/uploads\/2024\/04\/23163606\/pureLiFi_LINXC_Bridge_puck.jpg\")
