Broadcom Unveils LTE-Advanced Modem for Smartphone and Tablets
Broadcom has introduced the 28nm 4G LTE-Advanced modem with integrated radio and cellular baseband which reduces board area by approximately 35 percent. Designed for the 4G LTE market, Broadcom's BCM21892 multi-mode, multi-band solution supports all 3GPP standards technologies including 4G LTE-Advanced with carrier aggregation, HSPA+, TD-SCDMA and EDGE/GSM.
According to Broadcom, its advanced power management techniques save up to 25 percent of the power typically consumed during data transmissions to the network. The new modem also supports LTE Category 4 speeds of 150Mbps and performs seamless hand-offs between the various 4G LTE, 3G and 2G interface technologies.
Company further adds that the BCM21892 features an integrated world-band radio that can support virtually any designated 3GPP LTE frequency band and combination, a critical capability as operators prepare their networks for 4G LTE roaming. It also supports a Voice over LTE (VoLTE) solution that consumes approximately 40 percent less power than a comparable WCDMA voice call.
