Marvell has launched a new chip for better wireless data networking on smartphones.

The new chip has LTE TDD/FDD capability and works with Marvell’s new quad-core “world phone” processor that was announced yesterday.

At the Mobile World Congress event in Barcelona next week, Chinese gadget maker ZTE will debut a phone using the Marvell LTE solution. The product is expected to come out some time this year.

Santa Clara, Calif.-based Marvell said its LTE (Long-Term Evolution) data networking modem has support for all global 3G and 4G broadband wireless standards, enabling seamless global roaming. It features support for 5-mode cellular modems, including LTE TDD and FDD, High Speed Packet Access Plus (HSPA+), Time division High Speed Packet Access Plus (TD-HSPA+) and Enhanced Data for GSM Environment (EDGE). That means it works in a bunch of territories where those standards are in use in wireless data networks.

“Marvell has accelerated the pace of innovation and commercialization by bringing our industry leading TDD-LTE and FDD-LTE solutions into our quad-core mobile platform. We believe that with our design win success we can support our partners to accelerate the mass adoption of LTE solutions around the world,” said Weili Dai, co-founder of Marvell, in a statement.

ZTE will show a dual-radio, dual-standby LTE smartphone demo.
