What it is…
Anadigm's RangeMaster and RangeMaster2™ is a family of RFID reader solutions for Universal UHF RFID Tag Reader Systems.   The RangeMaster™ chipset family provides the industry's first solution that allows system vendors to design and maintain a single "universal" reader that can be customized to read different radio frequency identification (RFID) tag types, with different modulation schemes and frequencies. RangeMaster2™ fully supports EPC Global Gen 1 and Gen 2 (class 0, 1, 2) and ISO18000-6, 14443, 15693 standards.

RangeMaster2™ is a 3.3volt device while RangeMaster1™ supports a 5volt supply, they are both two-chip solutions that use a customized dpASP (dynamically programmable Analog Signal Processor) in conjunction with an RFID State Machine, enabling system designers to develop a universal RFID tag reader that can support multiple protocols and frequencies for Universal Fixed Readers, Portable/Handheld Readers, Combination Bar Code and RFID Reader/Scanners. By allowing standardization around a single printed circuit board to support multiple end products and markets, RangeMaster simplifies and improves product development. This allows customers building RFID tag readers to greatly reduce their time to market, and offer a lower total cost of ownership
