The adoption of Wireless HID accessories for PCs is increasingWireless HID provides a superior user experience with high reliability
The price difference between wireless and wired HID has narrowed, eliminating barriers to adoption
The battery life of Wireless HID has increased to more than three years, improving user convenience
Add wireless capability to your next HID designs with Cypress’s WUSB-NL solution
Wireless HID is Proliferating
Market Vision: To define the market opportunity. Presents compelling data and end product photos relevant to the local market. Should use compelling photographs of actual Wireless HID products.

Terms You Will Hear Today
Terms of Art (ToAs): To clearly define tor engineers all ToAs used in the presentation. To carefully and fully define Cypress-proprietary ToAs needed to explain our system solution.
HID (Human Interface Device)Keyboard, mouse or any other device that connects people with PCs and other systems
RF (Radio Frequency) CommunicationWireless Communication that uses radio waves to carry data
RF TransceiverAn IC capable of both transmitting and receiving RF communication
2.4-GHz BandA frequency range of 2.4 GHz to 2.5 GHz used for RF communication
This band is available worldwide without the need for licensing
AES (Advanced Encryption Standard)An algorithm used to encrypt wireless transmission
Helps to secure transmitted HID data, such as typed keystrokes
COB (Chip-on-Board)Unpackaged chip directly connected to a printed circuit board
Very-low-cost electronic assembly technology
Report Rate Number of times per second a wireless HID device sends information to a PC, typically 125 Hz
A report rate below 80 Hz causes missed clicks or keystrokes

WUSB-NL TermsAgileHIDTM
Cypress's proprietary wireless firmware protocol for RF data transmission
Provides immunity to interference generated by other nearby 2.4-GHz wireless devices, such as WiFi
WUSB-NL (WirelessUSB-NL)Cypress’s third-generation, low-power RF transceiver that features AgileHID protocol
Enables wireless devices to communicate with one another at a range of up to 30 meters
Enables mice to operate for three years on two AA batteries
enCoReTM (enhanced Component Reduction)Reprogrammable, low-power, low-cost microcontroller used to implement the USB protocol
Integrates RAM, USB circuitry, and a clock generator to reduce overall system costs

Design Problems Engineers Face
1. Customers require minimum three-year battery life in Wireless HID solutions
2. These solutions must be cost-comparable with wired HID devices to drive mass adoption
3. They must also provide superior interference immunity for optimal user experienceThe proliferation of wireless consumer devices has crowded the 2.4-GHz Band
This proliferation has degraded HID performance (e.g., missed mouse clicks)
Cypress's WUSB-NL solutions solve these problemsEnable battery life of more than three years with best-in-class system power consumption
Support COB to reduce wireless HID system cost
Use the AgileHID protocol to provide interference immunity from other 2.4-GHz wireless devices
WUSB-NL solutions ensure reliable transmission with long battery life and low solution cost
Traditional Approach and Challenges: To present the traditional approach and the challenges engineers will face when using it to realize the Market Vision. Ends with a one-sentence segue clearly stating the benefit of the Cypress solution.
“The Cypress WUSB-NL and enCoRe solutions were important components in the BORND E220 mouse, and the super-long battery life and long-range connectivity have attracted interest from the market.” – Kevin Zhang, General Manager of BORND
