New Wi-Fi chips increase performance by 10 times
A new type of radio chip, when used for cell phones and Wi-Fi / Bluetooth devices, will be able to cut power consumption by up to 10 times. Developed at the University of Rochester, New York, this type of chipset uses a technique called Locked Frequency Division (ILFD).
A new type of radio chip, when used for cell phones and Wi-Fi / Bluetooth devices, will be able to cut power consumption by up to 10 times.
Developed at the University of Rochester, New York, this type of chipset uses a technique called Locked Frequency Division (ILFD). This technique allows lowering the power required to transmit and receive data up to 90%.
In order for the two users to communicate with each other via radio waves, they must be in the same frequency. Therefore, the phone needs to maintain the "meter" accurately and stably thanks to a special circuit board with a single-phase circuit. However, this board consumes power "frantically" and significantly shortens the battery life of wireless devices.
Compared to traditional numerical methods that use 0.1 sequences, project director Hui Wu said that ILFD is much more energy-efficient, because it uses analogue methods to count fluctuations.
Actually, in the past, ILFD technology was considered but was temporarily suspended due to limitations in capturing the right frequency. However, Professor Wu affirmed that it has been overcome by increasing the number of transistors on the set chip, allowing for more sensitive and accurate frequencies.
With the sample chipsets currently in the lab, Professor Wu said the performance is very positive, and he hopes to continue developing ILFD to create more energy-efficient chipsets.
