Broadcom Announces New Feature-Rich 802.11n VoIP Router Solutions with 3G USB Modem Support

System OEMs can now leverage unparalleled Broadcom® wireless silicon integration and a proven VoIP software suite to develop advanced routers. 3G functionality can be added to these new platform solutions using a USB interface, bringing Internet and network services to homes where broadband is otherwise unavailable.



Highlights/Key Facts:

• 3G USB modems enable consumers to utilize their cellular network to create an instant Wi-Fi hotspot for whole home Internet and VoIP services. According to InStat, revenues from external 3G modems alone will reach $2.34 billion globally by the end of 2010.



• Running a VoIP stack on the wireless router enables consumers to make high quality phone calls over the Internet. VoIP routers bring cost benefits to consumers since calls are charged as part of the Internet service instead of a separate regular telephone charge. Added services like multiple lines, conference call and caller ID are also provided at no additional charge as part of typical VoIP offerings.



• Broadcom's 802.11n design platform with external 3G support includes router options for low-end to high-end solutions as follows:

o The Broadcom BCM5356U (a single-stream 2.4GHz IEEE 802.11n router SoC solution)

o The BCM5358U (a dual-stream 2.4GHz IEEE 802.11n router SoC solution)

o The BCM5358 (a dual-stream 2.4GHz IEEE 802.11n router SoC solution with VoIP support)

o The BCM47186 (a dual-stream 2.4GHz IEEE 802.11n high-performance Gigabit Ethernet router SoC solution with VoIP support)



• To provide a strong wireless backbone for the networked home, Broadcom optimized this new 802.11n router platform with Accelerange™ technology – a unique set of hardware and software enhancements that ensures more robust wireless coverage.



• The powerful 533 MHz MIPS32 74K core CPU memory subsystem architecture allows for consistently enhanced voice quality even under high Internet data traffic conditions.



• Broadcom uses a 65 nanometer CMOS design process and a high level of integration to reduce the number of system components on-chip, which in turn, lowers the rest-of-bill-of-materials (RBOM) cost by up to 35 percent. These new router SoC solutions further reduce cost by using two-layer printed circuit boards (PCBs), making high-end routers more affordable to consumers.



• The new Intensi-fi XLR platform builds upon the architecture of Broadcom’s current 802.11n platform, and maintains data rates of up to 300 Megabits per second (Mbps).



• Broadcom’s proven VoIP solution includes:

o Pulse Coded Modulation (PCM) interface

o Variety of voice codecs including:

• G.711

• G.729A+B

• G.722

o Caller ID and progress tone generation

o Echo cancellation

o 2 FXS voice ports

o T.38 fax relay

o 3-way conference call support



• Other key features of these new SoC solutions include:

o Interface to support 3G and 4G technologies including WiMAX and LTE (long term evolution) WAN connectivity

o Integrated IEEE 802.11n CPUMAC/BB/Radio

o Memory controller and five-port Fast Ethernet switch

o Integrated 2.4 GHz power amplification circuit

o USB 2.0 host port that can be used for storage and print server applications

o Low-power modes for a green router footprint
