25. therefore the RFD21733 is the primary choice by many engineers The RFD21735 is typically used if you must have an external antenna however we always recommend first looking at the RFD21743 which already has an FCC Approval and is in the form of an external antenna The RFD21743 is FCC Modular Approved and Certified therefore for use of the RFD21743 module in your product does not require further FCC testing Detail instructions and FCC notices shown later in this data sheet Any modifications made to the RFD21743 will void the FCC Approval and Certification The RFD21743 has an integrated antenna You simply include the RFD21743 in your product and follow the FCC notices and information below and place the appropriate label on your product to indicate that it includes an FCC approved module and no further testing would be required for the module The RFDANT RFD21743 is a great alternative to needing to get your own FCC approval with the RFD21735 combined with your own antenna The RFD21743 has an excellent antenna pattern which provides about 4 times more range than a RFD21733 and does not require mounting to your PCB since it has its own antenna enclosure More details about it below in this data sheet It should be considered before starting your design with an RFD21735 and your own external antenna since it accomplishes the same task without the need for further compliance approvals CE ETSI Compliance Information The RFD21733 RFD21735 RFD21
26. ww RFdigital com Email support rfdigital com RFD21820 RFDP8 INTERFERENCE IMMUNITY PROTOCOL RF Digital s RFDP8 proprietary patent pending frequency agility protocol operates in the internationally accepted 2 4 GHz band The RFDP8 s leading edge advanced algorithm is not burdened by a heavy weight stack as is BlueTooth ZigBee WLAN and other protocols which are well suited for cross manufacturer interoperability The RFDP8 protocol is highly robust and effective where there is a need to penetrate through a high saturation of RF noise which is common in nearly all environments today It is especially effective and can easily coexist in heavy WiFi environments which very few technologies can do successfully without the need of excessive processing power The protocol strategically changes channels frequently to deliver its payload to the destination device reliably yet not too excessively as to demand too much internal processing power which allows it to run with a very low current consumption profile and fast start up times allowing substantial flexibility with implementation The RFDP8 protocol reduces the amount of on air traffic and unnecessary chatter due to its unique and highly efficient design which does not require bilateral registration and association as do many other technologies today The RFDP8 does not require ack nacks to complete a packet delivery its unique technique of packet delivery recovery and correction allows it t
