According to research firm Strategy Analytics, Qualcomm, MediaTek, Intel, Spreadtrum and Broadcom captured the top-five revenue share spots in the cellular processor market. Qualcomm maintained its dominance with 66 percent revenue share, followed by MediaTek with 12 percent revenue share and Intel with 7 percent share.

However, according to Strategy Analytics, Qualcomm has around 95 percent of revenue share in the LTE baseband segment, thanks in part to the $14 billion in research and development the company has spent over the last four years. Qualcomm’s new Snapdragon 410 chipset has an integrated 4G LTE World Mode.

Huawei’s 6.1-inch Ascend Mate2, a 4G phablet introduced at CES, uses Qualcomm’s MSM8928 modem which supports all the usual air interfaces – CDMA/EVDO in addition to WCDMA, GSM, TD-SCDMA, FDD-LTE and TDD-LTE.

Hermann Eul, vice president and general manager of Intel’s Mobile and Communications Group, said Intel is now the No. 2 chipset vendor in terms of shipping LTE chips.

MediaTek and VIA Telecom have collaborated to support Worldmode global roaming of voice and data services across CDMA2000, LTE (TDD and FDD), DC-HSPA+, UMTS, TD-SCDMA and GSM/EDGE networks. It will support interoperability between CDMA2000 and LTE modes for the US and China, with handover for seamless switching. The SOCs will also be software upgradeable to support VoLTE (Voice over LTE).

Broadcom acquired LTE-related assets from Renesas in September and Broadcom’s M320 dual-core LTE System-on-a-Chip will be shipping in at least one Samsung phone in the first quarter.

ZTE’s 6.9″ Grand Memo LTE smartphone has achieved China Mobile TD-LTE certification using Marvell’s multi-mode 4G LTE modem, according to the chipmaker, even though it’s powered by Qualcomm’s 800 series chips (in some models). The Marvell PXA1802 modem integrates TDD, FDD, LTE, TD-SCDMA, WCDMA and EDGE technology onto a single chip that is fully backward compatible with current China TD-SCDMA standards. The ZTE Grand Memo LTE features Marvell’s 88RF838 transceiver, 88PG8211 and 88PM809, according to Marvell.

The first products with Nvidia’s Tegra 4i chipset, which combines the company’s application processor with an LTE modem, will be available in the first half of 2014, but likely will not be aimed at the U.S. market, according to CEO Jen-Hsun Huang.
