Compared with the traditional indoor distributed DAS (Distributed Antenna System), the QCell solution realizes the transformation of indoor coverage from feeder cables to Ethernet cables, solving the problem that a large number of feeders cannot be deployed indoors or the deployment of feeders is difficult. QCell can be applied to scenarios such as metro rail coverage, coal mine applications, airports, large hotels, commercial shopping malls, high-traffic office buildings, etc. The overall architecture of the QCell solution is divided into three levels, namely the Base Band Unit (BBU), the Pico Remote Radio Unit Bridge (P-Bridge), and the Pico Remote Radio Unit (PicoRRU). The BBU and P-Bridge are connected via optical fibers, the P-Bridge and PicoRRU are connected via Ethernet cables, and cascading between P-Bridges can also be realized using optical fibers. As the transmission and conversion device in the QCell solution, the remote aggregation unit P-Bridge completes the functions of signal conversion from optical ports to Ethernet electrical ports, downlink signal splitting, and uplink signal combining, and can supply power to the remote PicoRRUs through POE (Power over Ethernet). The corresponding device model is ZXSDR PB1120B.\u003c\/span\u003e\u003c\/p\u003e","brand":"Caltta","offers":[{"title":"Default Title","offer_id":49673115304192,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0840\/0034\/2272\/files\/LTE_daf580bf-1b02-4b58-9025-3a0f5c57e3b4.png?v=1788407453","url":"https:\/\/www.trbow.com\/products\/caltta-lte-remote-aggregation-unit","provider":"Trbow Solutions","version":"1.0","type":"link"}
