Broadcom announced a 28nm 4G LTE modem with integrated radio and cellular baseband reduces board area by approximately 35 percent while supporting LTE-Advanced with carrier aggregation, HSPA+, TD-SCDMA and EDGE/GSM.
Broadcom's multi-mode, multi-band solution – the BCM21892 – is aimed at next generation 4G LTE smartphones and tablets. The device combines a full-featured cellular baseband with a world-band radio that can support virtually any designated 3GPP LTE frequency band and combination, which aids in 4G LTE roaming. The LTE-Advanced capability will support LTE Category 4 speeds of 150 Mbps with seamless hand-offs between the various 4G LTE, 3G and 2G interface technologies.
A Voice over LTE (VoLTE) solution that enables high-definition voice calls. Broadcom estimates its VoLTE service consumes approximately 40 percent less power than a comparable WCDMA voice call.
Significantly, Broadcom said its design employs advanced power management techniques that can save up to 25 percent of the power typically consumed during data transmissions to the network.
"Broadcom's new 4G LTE modem combined with our Wi-Fi, Bluetooth, GPS and NFC technologies gives OEMs all the communications technologies needed to build advanced devices that will offer consumers the features, speed and functionality they demand in their next smartphone purchase," said Robert A. Rango, Broadcom Executive Vice President and General Manager, Mobile and Wireless Group. "Broadcom's 4G LTE modem will also help carriers drive new 4G LTE features, such as carrier aggregation, into commercial networks."
BCM21892 is now sampling to early access customers, with anticipated production in 2014.
