GuardEdge GE28 is a 6G edge-awareness chiplet that turns the base station from a data pipe into a real-time sensor. Future factories, smart streets, autonomous robots, private networks, and safety systems need the same thing. They must communicate, sense, and react inside an ultra-reliable low-latency loop. Today, that loop is split across radios, radar modules, cameras, CPUs, memory copies, and cloud software. GE28 compresses it into one Integrated-Sensing-And-Communications digital baseband platform.

The core innovation is a node-partitioned chiplet architecture. The RF and analog functions stay on a mature die where PA, LNA, PLL, mixer, ADC, DAC, and beamforming blocks are cost-effective. The compute-heavy digital baseband moves to an advanced-node die. A UCIe 1.1 or 2.0 style bridge on a common organic substrate carries more than 230 Gb/s of converter data through thousands of microbumps, with a target below 0.5 pJ/bit and no costly silicon interposer. This makes the package both high-performance and manufacturable.

Inside the digital die, GE28 is not a generic DSP block. A high-speed link adapter and Digital-Front-End absorb the raw RF stream, perform down-conversion, CIC and polyphase FIR decimation, crest-factor reduction, digital pre-distortion hooks, and fixed-point signal-quality control before the ISAC core ever sees data. The sensing engine then builds range-Doppler maps, runs CFAR and event extraction, and adds spatial angle-of-arrival acceleration for array sensing. The communication branch frames traffic through O-RAN Split 7.2x and eCPRI, so the same silicon can sit naturally beside 5G-Advanced and 6G O-RU infrastructure. A compact SFFT-oriented sensing core targets 0.6× area and energy versus a baseline FFT while keeping at least 15-bit precision.

The most important architectural benefit is latency determinism. Instead of sending samples through the host CPU, GE28 writes the range-Doppler map once into shared SRAM. A zero-copy buffer lets the AI or fusion block read it in place through a coherent TileLink path, targeting sense-to-action latency under 15 ms. A power-management controller scales voltage and clock domains with the decimation rate, gates idle DFE, sensing, communication, and always-on control blocks, and wakes islands without breaking the deadline.

GE28 is also designed as a business platform. Tier 1 is hardened RTL and accelerator IP with AXI4, IP-XACT, SystemVerilog, verification harnesses, and PPA reports. Tier 2 is firmware, SDK, HAL, register maps, signed profiles, and license gating. Tier 3 is application software for telecom, smart infrastructure, non-contact health sensing, and short-range automotive-support profiles. One silicon core can become multiple recurring products.

Feasibility follows an industry silicon path. The flow starts with MATLAB reference models, moves to fixed-point RTL, initial RFSoC testbed, functional verification, synthesis, floorplan, GDSII signoff preparation with STA, DFT, EM/IR, DRC/LVS/ANT/PERC, post-silicon validation, industrial standard compliance, and O-RAN interoperability. For operators, OEMs, and infrastructure vendors, the benefit is direct. Fewer boxes, fewer copies, lower latency, software-defined sensing features, and new revenue from the same deployed silicon. GE28 is not just an ISAC concept. It is a manufacturable route to the multibillion-dollar 6G edge market, as ISAC revenue could approach 28 billion dollars by 2032 across deployed networks.
