Cambridge-based Forefront RF has raised £1.5 million to propel its efforts to redefine the way smartphones, wearables, and IoT devices are designed. With the funding, the company is planning a recruitment spree, ultimately accelerating the firms’ time to market.
One of the key components in a modern wireless device is the radio frequency system, and more specifically, how it operates and communicates on a specific frequency band, i.e. 3G, 4G, 5G, etc.
The current solution is to provide RF filters and switches for each frequency band that overrides a devices’ signal of self-interference, but allows the desired signal through to the receiver. Forefront RF is saying adieu to the multiple filters and employing technology similar to that of noise-canceling headphones. Essentially, instead of manual filters, Forefront is embedding software in a chipset that maintains the accuracy but at a fraction of the cost and materials needed to produce.
“The growth in mobile networks driven by the ever-increasing demand for data means that available frequency bands vary from region to region and, using today’s technology, has driven the need for region-specific smartphone variants each including multiple RF components,” commented Laughlin. “The space consumed within each smartphone adds cost and leads to inefficiencies in the supply chain.”
