Typical Applications
The CPS-1848, in tandem with other RapidIO ecosystem switches and endpoints, enables next-generation compute density
and power efficiency. This significantly increases channel capacity for 3G to 4G wireless infrastructure, media gateways, video
conferencing, and military and medical imaging systems. Full peer-to-peer networking makes systems of arbitrary topology
possible.

Wireless Application Benefits
• Carrier-grade reliable packet transport
• Gen2 performance to power ratio allows unprecedented compute density to enable 3G and 4G systems
• Switched architecture allows highly scalable system for micro and macro BTS implementations
• Carrier-grade 6.25 Gbaud SerDes enables backplane-based modular systems and system scaling by inter-chassis cabling
• Ecosystem-standard support for four priorities plus Critical Request flow provides strong QoS support for multiple data
flows plus control plane
