Arsitektur Open RAN yang memanfaatkan small cell adalah salah satu skenario penerapan yang sangat cocok untuk jaringan 5G private. Hal ini karena open sistem menyediakan berbagai pilihan bagi vendor dan operator untuk menyesuaikan solusi yang paling sesuai dengan kebutuhan masing-masing pelanggan. Selain itu, memelihara jaringan pribadi dengan platform terbuka jauh lebih sederhana dibandingkan dengan model tradisional.

Solusi Comba Open Platform Small Cell mencakup open-platform small cell dari sistem base station terdistribusi kecil, berdaya rendah, yang mengadopsi teknologi digital dan infrastruktur fiber, menyediakan sinyal jangkauan dalam ruangan 5G. Ini berkontribusi pada infrastruktur TI yang hemat biaya dengan perencanaan kapasitas sesuai permintaan menggunakan pemisahan sel tanpa modifikasi infrastruktur untuk rapid deployment.

DP (Distributed Unit) tersambung ke SW (Extension Unit) dan berfungsi sebagai penyedia sinyal seluler aktif. Transceiver berdaya rendah ini menghadirkan kinerja tinggi untuk jangkauan distribusi radio 5G dalam ruangan.

DP

NR N41 and N78

50/ 60/ 80/ 100MHz

SW (Extension Unit) is the data aggregation and forwarding part of Open Platform Small Cell. It can greatly increase the small cell coverage by daisy chain connection. The switch handles data transport, as well as downlink distribution and uplink aggregation.

  SW

AU (Access Unit) is the baseband of Open Platform Small Cell solution which connects to core network through IP interface and provides cellular signal for users. The unit directly connects to core network and performs 5G radio physical layer and upper layer protocol processing.

Why small cell is important to Open RAN fragmentation?

Since 5G NR NSA (non Standalone) still uses the existing 4G core, it is very difficult to add 5G equipment from a different supplier from the 4G system, because crucial interfaces like X2 are implemented differently by each vendor. These migration challenges are redoubling operators’ determination to support fully unified interfaces for their next deployments, and the best place to start is often in the relatively greenfield roll-outs of small cells.

Comba Open Platform Small Cell solution is able to accomplish what the enterprise and the carrier needs. It will support multi-vendor interoperability between different components at different layers of the network, reflecting different 3GPP functional splits. As it evolves, it will have the flexibility to support different splits, and so improve the future-proofing of small cell deployments.
