The OCT2224W is part of the OCT2200 series of devices, targeted at wireless baseband processing for Base Transceiver Stations (BTS).

The OCT2224W is a System-on-Chip (SoC) device optimized for GSM, HSPA and LTE baseband processing. It offers impressive power-efficiency consuming less than 5 watts while serving 64 users within a range of 20 km in HSPA.

OEMs can quickly develop multi-standard basestations thanks to the modular flexiPHY  software that comes pre-integrated with the device. This software supports major 3GPP releases. Click here for details on flexiPHY .

For non-commercial cellular applications including custom waveforms, customers can use Octasic’s Opus Development Kit (ODK). This low-level SDK provides all the necessary drivers and libraries to quickly build a custom wireless product.

The OCT2224W is highly integrated. It includes high-speed network interfaces as well as on-chip RF ports making it ideal for cost efficient small cell designs.
