Set-top box platform integrates 4×4 Wi-Fi
The BCM7250 and BCM72502 chips bring full-featured set-top box functionality to compact HDMI stick and popular streaming media player box formats, allowing carriers to deliver services wirelessly anywhere in the home, while taking up less space and with fewer wires with MHL powering.
Compact reference designs based on these devices also include integrated 802.11ac Wi-Fi capabilities. This includes the BCM4366, which claims to be the fastest 4×4 MU-MIMO device. The platforms securely deliver premium content in dramatically smaller and easy-to-install subscriber equipment with MHL 2.0 and up to 4×4 5G WiFi
"This new family brings a major boost in capabilities to what has been primarily an over-the-top (OTT) segment of the market," said Rich Nelson, Broadcom Senior Vice President of Marketing, Broadband & Connectivity Group.
The BCM7250 is targeted at the popular OTT streaming media player form factor and the BCM72502 is specifically designed for HDMI stick or dongle applications. The BCM7250 family and reference platforms provide 2×2 and 4×4 5G WiFi connectivity options via a high-speed PCIe interface.
The 4×4 5G WiFi option is powered by the BCM4366 device, which has been designed from the ground up to enable broadcast-quality video delivery over Wi-Fi. The BCM4366 incorporates a host of features targeted specifically to improve the robustness of wireless video transmission and provide wireline-quality performance over Wi-Fi. This enables equipment manufacturers to develop high-performance, secure, compact designs with reliable wireless content delivery and gives operators powerful solutions for no-new–wires easy customer installation.
These devices integrate advanced security engines that support a wide range of the latest conditional access and digital rights management technologies. This provides service providers and equipment manufacturers with new capabilities to securely support full IPTV multicast services, unlike existing devices that are typically limited to OTT streaming services. As a result, operators now have the capability to offer a range of services, from full-service IPTV with multi-room gateway/client architecture to a standalone dongle for an entry level OTT offering using the same platform.
