IN Brief:
- Fidus Systems will implement and validate selected PrismIQ functions on an FPGA platform before production silicon is available.
- The demonstrator will integrate Edgewater's Spectrum Slicing software and drivers and support over-the-air testing for prospective customers.
- Edgewater continues to target an initial PrismIQ product release in the first half of 2027, making this an evaluation milestone rather than a production launch.
Edgewater Wireless is preparing an FPGA demonstration platform for its next-generation PrismIQ wireless architecture, allowing prospective customers to evaluate selected functions before production silicon becomes available. Fidus Systems will provide implementation and system-validation support, while an Ontario Vehicle Innovation Network programme is contributing funding towards eligible engineering services.
The work centres on Edgewater’s Spectrum Slicing architecture, which is designed to operate multiple concurrent channels within one Wi-Fi band. Edgewater is developing PrismIQ against emerging Wi-Fi 8 requirements and intends to use the FPGA platform for hardware and software integration, over-the-air validation, and demonstrations with prospective customers.
Fidus will implement and validate selected PrismIQ functions in programmable logic and integrate Edgewater’s software and driver environment. The resulting platform gives customer engineers access to a hardware implementation before the architecture is committed to a production ASIC, providing an opportunity to examine interfaces, system behaviour, and integration requirements while changes remain comparatively inexpensive.
An FPGA is useful at this stage precisely because it is not the final silicon. Logic, interfaces, memory paths, and control functions can be modified without a new mask set, allowing faults and architectural assumptions to be tested before semiconductor implementation. It can also provide more representative customer hardware than a software model when gateway or access-point manufacturers begin integrating their own control software and surrounding electronics.
The differences between an FPGA prototype and a production device remain substantial. Clock speed, power consumption, die area, memory architecture, packaging, RF integration, thermal performance, test strategy, and manufacturing yield can all change once the design moves into dedicated silicon. Customer evaluation of the demonstrator therefore establishes functional behaviour and integration requirements rather than the final electrical or commercial performance of PrismIQ.
Edgewater says Spectrum Slicing enables multiple concurrent channels within a Wi-Fi band and is intended to improve usable capacity, latency, and reliability in congested environments. Those are company claims around the architecture rather than established outcomes for the forthcoming PrismIQ product. Performance in a deployed network will depend on RF conditions, client behaviour, standards implementation, scheduling, software, antenna design, and the rest of the access-point or gateway system.
The programme also gives Edgewater a route to discuss possible design-ins and intellectual-property licensing before production silicon is complete. Early customer input can expose requirements that are expensive to discover after tapeout, particularly around host interfaces, firmware, driver behaviour, memory use, diagnostics, and system control. The value of the demonstrator is consequently as much about finding incompatible assumptions as showing working functions.
Funding support comes through the OVIN Semiconductor Voucher Program. Edgewater was approved in August for a voucher of up to C$20,000 for eligible technical services, subject to completion and acceptance of defined project milestones. The amount represents only a small part of the cost of developing production silicon but offsets some specialist engineering work during the prototype phase.
Fidus provides FPGA, ASIC RTL, verification, embedded software, high-speed hardware, signal and power integrity, mechanical, and thermal engineering services. That breadth reflects the number of disciplines involved when an architecture starts moving beyond RTL. Driver interfaces, power delivery, board constraints, software integration, validation, and eventual RF implementation all begin to affect the production device before physical silicon exists.
Edgewater continues to target an initial PrismIQ product release in the first half of 2027. The current milestones are hardware and software integration, over-the-air validation, and customer demonstrations rather than production qualification or volume availability. No finished PrismIQ chip is being offered as part of the September announcement.
The distinction is important for a wireless architecture still moving towards silicon. FPGA demonstrations can establish whether the functions work and whether prospective customers can integrate them, but they cannot establish the economics, power, RF behaviour, or manufacturing performance of the final component. PrismIQ has reached a useful customer-evaluation step; the production-device evidence is still due in 2027.
