Efforts to increase capacity and extend coverage have continued through antenna technology advancements. Increasing capacity by dual orthogonal polarization technology and extending coverage by narrow multi-beam are the best examples. However, dual orthogonal polarization technology results in deterioration of capacity due to correlation by the overlap of polarization in multiple MIMO environments, and narrow multi-beam technology has a limitation that extends coverage. However, capacity increases are low due to the correlation between antenna polarizations. The limitations of these technologies occur because the same polarization is used in the same space, at the same time, and at the same frequency. In a new whitepaper , KMW announced that they have implemented OPRA that has applied Orthogonal Polarization Reuse to increase capacity and extend coverage simultaneously. KMW is ready to offer a variety of RU products powered by OPRA technology to global partners and customers. Orthogona...

We have done multiple posts on our blogs looking at Fixed Wireless Access (FWA). It all started with this tutorial here . 5G FWA was one of the most popular services being offered by the operators.  Late last year, the Global mobile Suppliers Association (GSA) announced the establishment of the GSA 4G-5G fixed wireless access (FWA) forum to bring together leading chipset, module and terminal vendors—as well as other telecommunications industry representatives, who wish to promote 4G and 5G FWA technology, products and services—to report on progress of FWA deployments, identify use cases and encourage global adoption.  At the recent GSA 4G-5G FWA Forum, Simon Sherrington, VP Research, GSA, presented the status of Fixed Wireless Access. Some of the highlights from his talk: FWA investment is global At least 477 operators in 175 countries/territories catalogued as investing in FWA based on LTE or 5G Trials, pilots, deployments, commercial launches or investment in licences GSA h...
