Broadcom's new system-on-a-chip: Gigabit bandwidth for 4G/LTE

Summary:Semiconductor specialist Broadcom's new BCM85620 system-on-a-chip (SoC) can manage 1.25Gbps throughput for 4G/LTE applications.

Semiconductor specialist Broadcom on Wednesday announced that its BCM85620 system-on-a-chip (SoC) is the first to manage Gigabit bandwidth as well as combine a baseband modem and network processor in one chip.

The chip is designed for 4G/LTE microwave backhaul -- that is, when wireless carriers backhaul data from cell sites to their core networks. It's an expensive process that's only going to get worse as faster wireless devices reach the market and consumers boost their data consumption from activities such as streaming video. (Yes, Mr. NFL all-season pass, that means you.)

How expensive is expensive? A global mobile backhaul spend of about $8 billion by 2014, according to Infonetics data.

Broadcom says the SoC can manage 1.25Gbps throughput and 25 percent higher capacity than what's on the market today. It is among the first products to demonstrate tech from the company's acquisition of Provigent six months ago.

The new SoC is available now.
