Wireless labs can often have many Remote Radio Units or Remote Radio Heads (RRUs/RRHs) to manage. To conduct testing, these RF ports are connected to RF attenuation equipment before being routed to RF testing stations.
Acentury Inc. played a vital role in empowering mobile carriers to enhance their network coverage within the TTC. RF attenuators are essential components that control and manage signal strength, ensuring optimal connectivity within tunnels and stations.
Mobile carriers have invested considerably in deploying 5G New Radio (NR) and 5G standalone (SA) networks. One of the most promising features of 5G Standalone (SA) to help monetize new services for subscribers is Network Slicing.
A Canadian Tier 1 operator was deploying their active DAS system where they encountered challenges with rack space for attenuators. To solve this problem, they were looking for a compact-sized attenuator design that could fit as many units as possible per rack shelf.
The Canadian government introduced new spectrum licensing rules through Innovation, Science and Economic Development Canada (ISED), allowing private 5G networks, with licenses issued under a Non-Competitive Licensing (NCL) model.
To simulate a handover, testers must precisely control RF signal strengths from two or more sites simultaneously. Techniques such as MIMO and Carrier Aggregation (CA) combine multiple RF signals together to improve network performance, but testers must manipulate many different signals simultaneously to properly simulate a single handover.
