An increasing number of routers are adopting a modular approach to management and upgrades. The benefit is that product lines can be recombined intelligently to meet different user requirements, maximizing product performance while minimizing customer investment and winning customer approval.
First, through the integrated PCIe interface and corresponding driver software, proven WLAN 802.11n and 802.11ac Wi-Fi solutions can be integrated into access products, enabling multi-mode access devices that simultaneously include carrier-grade Wi-Fi and cellular technology solutions. This achieves an overall increase in mobile network data capacity and supports smooth upgrades and evolution from 3G to 4G LTE, thereby improving the data transmission capacity and service coverage of mobile networks, ultimately enhancing users’ quality of experience and satisfaction.
Second, the chip’s software interface ensures excellent software compatibility across products, guaranteeing that 3G customers only need to add next-generation 4G LTE protocol software capabilities in multi-mode product software development. The chip’s ultra-low-power design allows small cell access devices to be powered via Power over Ethernet (PoE), simplifying power supply requirements and reducing device packaging size, which ultimately lowers product bill of materials costs. Meanwhile, the chip design highly integrates 3G and 4G LTE physical layer designs, further reducing memory footprint, associated costs, and power consumption requirements.
Third, through high integration, Broadcom’s dual-mode small cell system-on-chip single-chip solution reduces the overall bill of materials cost and power consumption of small cell access devices. As mobile operators continue to pursue faster data rates and better service quality, dual-mode chip solutions support seamless evolution and transition for service providers and operators from 3G to 4G LTE, along with mobile end users’ consistent pursuit of high-performance mobile service experiences.
Fourth, it supports dual-mode concurrency, delivering 150 Mbps downlink and 50 Mbps uplink physical layer data rates with 128 concurrent service users in 4G LTE 20 MHz channel bandwidth, and 32 concurrent 3G service users with 42 Mbps downlink and 11 Mbps uplink data rates in 3G WCDMA mode.
Fifth, the industry-leading solution supports 4G LTE 40 MHz channel bandwidth and 256 concurrent service users, or 64 concurrent 3G service users with 84 Mbps downlink and 22 Mbps uplink data rates in 3G WCDMA mode. The same chip supports LTE in either Frequency Division Duplex (FDD) or Time Division Duplex (TDD) modes, making it suitable for global markets.
Sixth, the lowest-power small cell baseband chip simplifies bill of materials costs and reduces the need for external peripheral circuits
