 variety of applications and market segments from high performance 4.75G (CAT12) solution to low power, low performance 4G IoT (CAT-M1/NB1). We offer baseband modem solutions to encode and decode data based on 4G protocols that serve as the core wireless processing platform for a 4G device; RF transceivers to transmit and receive wireless transmissions; and highly integrated SoC solutions that combine these and other functions into a single die or package. Our SoC solutions integrate the baseband modem and RF transceiver functions, and in some cases, with an applications processor and memory. This advanced level of integration reduces the size, cost, design complexity, and power consumption of the 4G solution. All of our baseband modem SoC products are provided with comprehensive software, including relevant source code, to enable manufacturers to efficiently integrate our solutions into their devices in a wide variety of environments. In addition, we provide customers with design support. This includes reference designs that specify recommended methods for interconnecting our chips to peripheral devices, such as host processors, memory and RF front-end components. Further, we provide customers with a warranty that our solutions are free from defects in materials and workmanship and will operate in material conformance with the provided specifications, entitling the customer to have the defective product repaired or replaced. 7 In addition to our various 4G LTE solutions that are currently available to our customers, we also have a number of 5G NR solutions in development that are expected to become available during 2025. Our products, including the expected availability of those products currently in the design stage of development, are summarized in the table and future roadmap below.
