More on 2.4 GHz technology
Initially, 27MHz and FastRF raised the standards of wireless performance, but did not systematically meet the specific requirements of the business environment where multiple users working in close proximity need devices which assure an interference-free operation. To eliminate this issue, Logitech integrated 2.4GHz as the RF performance standard for business solutions. Originally allocated for public communications, the 2.4GHz wavelength is relatively short and permits signals to easily navigate obstructions. Leveraging the wave characteristics of the 2.4GHz band, a cordless device can transmit large amounts of data in rapid bursts, making it faster and less susceptible to interference.

Brief History of Logitech RF Technology
The first generation of cordless mice, pioneered by Logitech in 1981, used infrared technology (IR) to communicate with receivers connected to PCs. While an infrared mouse provided a relative measure of freedom, it required a direct line of sight to an IR receiver. It also failed to approach the transmission rates of a corded mouse. Looking for ways to improve cordless performance, Logitech led the move from corded to cordless technology in 1984 with the revolutionary Infrared cordless desktop. In 1991, Logitech introduced the first RF cordless mouse quickly followed in 1994 with a 27MHz cordless mouse. 27 MHz products did not require a direct line-of-sight between the transmitter and receiver, and devices could send or receive waves that bounced off different surfaces. In 20XX (use MX 700 date) Logitech further improved the wireless performance of its products with its proprietary FastRF 27 MHz technology. The enhancements offered by FastRF included an increased reporting rate that is similar to the rate of corded USB devices. The technical advantages of FastRF gave users their first glimpse of a cordless experience that approached the performance of corded mice and keyboards. Once again taking the lead, Logitech has introduced 2.4 GHz wireless technology into some of its premium cordless products.
Delivering Commercial Peripheral Technology
The business world is becoming untethered. Increasingly, wireless technology is cutting the cords that bind us to fixed locations. Todays workers rely on an array of cordless devices: mobile phones, two-way pagers, Wi-Fi enabled laptops and PDAs. Cordless peripherals such as mice and keyboards, offer conveniences at the desk while reducing cable clutter. Compared to traditional corded devices, cordless devices offer clear advantages and can increase business productivity. The absence of tangled cords contributes to a cleaner work desk environment, which could in turn influence employees mood and creativity. However, until now, cordless solutions for keyboards and mice did not always adhere to the demanding requirements by businesses. Through everyday usage models, professional users have realized they want to eliminate problems related with interference, greater reliability and better power management. To answer these and other specific business needs, Logitech has brought to market the Pro 2400 Cordless Desktop.

2.4 GHz
27 MHz and FastRF raised the standards of wireless performance, but still did not systematically meet the specific requirements of the business environment, where too many people working in close proximity to each other generated some interference between their devices. To eliminate the frustration of possible interference of devices, Logitech selected 2.4 GHz as the RF performance standard for commercial usage models (see Table 1 below). Allocated for public communications, the 2.4 GHz wavelength is ideal for cordless operations. Its relatively short wavelengths permit signals that can more easily navigate obstructions. Taking advantage of the wave characteristics of the 2.4 GHz band, a cordless device can transmit large amounts of data in rapid bursts, making it faster and less susceptible to interference. As the 2.4 GHz band is also used by Bluetooth and WiFi (802.11) devices, the FCC (regulatory body) limited power output of the 2.4 GHz band to a maximum of one watt in order to restrain 2.4 GHz systems from overpowering each other. This limit established a safeguard for multiple 2.4 GHz solutions to function seamlessly in the same environment.

Frequency agility
Logitech 2.4 GHz Digital Cordless for Business features frequency agility. With this technology, the Logitech mouse or keyboard that encounters any interference from another cordless device will automatically identify and switch to a more quiet location in the band to transmit data. Furthermore, this process is so fast that most users will not notice it. This frequency agility ensures that virtually no device operating in the 2.4 GHz band will interfere with the optimal performance of the Logitech mouse and keyboard. Wi-Fi (802.11) network clients and servers, Bluetoothenabled devices, and cordless phones are all competing for bandwidth in this popular region of the radio spectrum. However, Logitech Pro 2400 Cordless Desktop confines its communications to channels unused by the majority of 802.11 solutions, further reducing possible interference from Wi-Fi devices. With a total of 78 discreet channels and over 65,000 possible ID codes, Logitech 2.4 GHz Digital Cordless for Business can easily support multiple 2.4GHz devices at a single location. TDMA spells error-free communications To further guard against signal interference, Logitech Pro 2400 Cordless Desktop uses a TDMA (Time Division Multiple Access) protocol to transmit packets. Widely used for cellular communications, TDMA sends data in small bursts rather than continuous streams, making its transmissions less prone to disturbances. The burst technique also permits multiple devices to use the same channel without interfering with each other. Logitech boosts the TDMA protocol with a sendacknowledgment technique that ensures that a base station receives all the packets sent to it. Pre-Pairing Logitech pairs each mouse and keyboard with the companion receiver during final manufacturing assembly. By matching ID numbers, the receiver knows which connections to accept and will simply not listen to other mice and keyboards that do not possess this ID. Thus, Logitech 2.4GHz Cordless Technology virtually eliminates dropped connections resulting from interference, giving users the increased confidence that comes with fault-free operation. This ID matching also allows a seamless installation. Simply plug the USB receiver into the PC and start working. Logitech Pro 2400 does not require the installation of any software or the establishment of the cordless connection through pressing buttons. Encryption Another benefit of Logitech 2.4 GHz Digital Cordless for Business is that it gives one of the fastest and most efficient cryptographic algorithms for keyboards and mice on todays market. Thanks to a 64-bit equivalent, proprietary TEA encryption algorithm, Logitech 2.4 GHz Digital Cordless for Business shows itself to be highly resistant to differential cryptanalysis, making it very difficult to break, even for an experienced hacker. Future directions Like other technologies, cordless is continually evolving. Logitech is committed to technologies that offer its customers the best performance benefits. With the Logitech Pro 2400 Cordless Desktop, Logitech demonstrates one of its core competencies the ability to enhance and extend the value of a platform technology with expertise tightly focused on improving the user experience. This same competency has allowed Logitech to stay at the forefront of the personal peripheral industry for over 20 years. As cordless technology continues to liberate users and transform social interactions, Logitech will remain at the leading edge.
