The 802.11ac IP solution is ideal for power sensitive applications such as smart phones, tablets, portable game console or digital cameras, but also digital TV, Set Top Box or Over The Top.
The licensable and silicon independent 802.11ac MAC and Modem core includes the lower MAC protocol software compliant with linux mac80211/cfg80211 UMAC. Combined with a 802.11ac radio IP, it allows customers to quickly develop high performance and cost effective 802.11ac solutions.
- 802.11ac MAC:
- The RW-WLAN-11nac MAC core implements the 802.11a/b/g/n/ac standard with throughput of up to 433Mbit/s for 1x1, up to 1.7Gbps for MIMO with 4 spatial streams. It also supports the 802.11e standard (QoS) and the 802.11i standard (Security) extensions.
- RivieraWaves' profound expertise in wireless communications resulted in the highly optimized MAC core with special focus on low memory and MIPS requirements while maintaining a small gate count. The MAC core interfaces to the ARM standard AMBA bus.
- 802.11ac Modem:
- The licensable and silicon independent RW-WLAN-11nac 802.11ac Modem core can be combined with the RivieraWaves RW-WLAN-11nac MAC IP to form high performance and cost effective 802.11a/b/g/n/ac solution. The supported features are:
