Atlanta 2000™ LTE Gateway Reference Design 50-0280-0001

LTE Gateway Reference Design (50-0280-0001)


The Atlanta 2000TM LTE Gateway reference design is an innovative HW/SW platform that enables Fixed Mobile (FMC) broadband service using LTE and Advanced LTE technology. In partnership with best in breed FDD and TDD LTE chipset and module vendors, TranSwitch delivers a solution optimized for Residential and SOHO deployments using EPC/e-UTRAN Wireless Service Provider networks. The range of applications supported includes: VoLTE, Video, WiFi, Data, Security and Home Automation.

The Atlanta 2000TM Dual Core + DSP communications processor offers wire-speed Gigabit routing performance for small packets, with scalability of up to eight low-bit-rate narrowband and/or wideband channels. It also utilizes a flexible memory controller fabric that enables native QOS on all interfaces, and a CPU architecture that enables it to achieve a higher performance, while consuming less power for environmentally conscious consumers. Coupled with the “TranSwitch LTE Gateway™ Software” package supporting all the drivers, protocols and stacks necessary, this manufacturing-ready integration of hardware and software increases time-to-market and lowers the bill of materials for OEMs and ODMs.”
