Increasing 5G Coverage and Capacity with OPRA (Orthogonal Polarization Reuse Antenna)

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.

Orthogonal Polarization Reuse, a technique that reuses different polarizations by separating time, space, and frequency, is a new paradigm that satisfies capacity increase and coverage extension by reducing correlation through existing polarization.

OPRA is an Orthogonal Polarization Reuse technology that uses different dual orthogonal polarizations. The representative polarizations used are Slant 45°(±45°) polarization and Vertical / Horizontal(V/H) polarization. OPRA reuses different dual orthogonal polarizations by separating time, space, and frequency to reduce correlation by polarization and increasing capacity, and extending coverage.

OPRA reuses different orthogonal polarizations on multi-beam, significantly reducing the correlation between beams, and increasing capacity by 36% and coverage by 39%. This OPRA technology can be implemented in both the RF domain and digital domain.

OPRA technology gives operators the ability to achieve increased capacity and extended coverage at a low investment cost, and paramountly reducing CapEx and OpEx. 

The whitepaper is available from here.

5G Connectivity will Enable New Use Cases

While we have been discussing advanced 5G use cases for years, it is only now, with the Standalone 5G (5G SA) that it is going to become possible to have many of these in practice. Of course they will take time to mature and be popular with the end users. As a part of our Free 5G Training initiative , we made a short video that will provide you with ideas and motivation for why 5G could do a lot more than just faster speeds. The video is embedded below. In addition, Parallel Wireless, one of the companies I consult for, did a webinar on 5G Use Cases which is available here .

Fixed Wireless Access (FWA) and the Path to 5G Wireless Wireline Convergence (WWC)

I have covered Fixed Wireless Access (FWA) on The 3G4G Blog here and looked at automated HetNet design which included FWA links here . I have also covered Wireline Wireless Convergence (WWC) as part of 5G and Fixed-Mobile Convergence (FMC) posts. The links to the posts are available at the end. Back in December, Juniper took part in a Light Reading webinar which is being shared as part of this post. With revenues flat and traffic continuing to explode, the unsustainable state of network economics needs another disruption. The 5G deployment cycle offers an insertion opportunity for new converged architectures. Wireless offload solutions can re-route the traffic of data-hogging mobile subscribers over wireline cores built for bandwidth and performance rather than mobile cores (EPC) primarily designed for mobility and portability. The 5G Network Architecture in 3GPP Release-16 allows the convergence of fixed and wireless networks. This also allows many new opportunities as can be se
