MaxStream Advantage

Addressing
MaxStream's full-featured configuration options allow for greater flexibility in integration than any other competing RF product line. MaxStream's RF modules can be configured to communicate in peer-to-peer, point-to-point, point-to-multipoint, multipoint-to-multipoint, and multi-drop networking topologies.

Module addresses and masks are also provided to set up global and local addressing schemes for establishing module groups, subnets, etc.

MaxStream radios utilize three layers of addressing filtration to communicate between radios. Only modules with the matching addresses are able to communicate. The three main networking layers are: Identification Number, Channel & Source/Destination Addresses.

Each networking layer provides a separate layer of filtration. The factory-set Vendor Identification Number (VID) provides the first layer of filtration. If the incoming RF data carries a matching VID number, the data continues through to the subsequent Channel and Module Address layers. The Module Address is the last networking layer and provides the most granular form of filtration. If at any point during the incoming RF data flow the numbers in question do not match, the data is discarded.

MaxStream radios are inherently peer-to-peer instead of client / server (master / slave). This means that modules communicate with NO configuration and support very flexible networking topologies. In the default mode of operation, the modules initialize the communication channel (synchronize transmitter and receiver) before each communication. MaxStream modules have no problem streaming data at 9600 or 19200 baud as rated. Re-synchronizing with each transmission allows the system to recover quickly from interference. A module can communicate immediately after power up without waiting for any synchronization. Also, there is no need to stay synchronized during sleep or low power modes allowing MaxStream to have power down modes as low as 20 micro-amps. Configurable low latency operating modes reduce the synchronization time to as little as 8ms.

Networking Modes
MaxStream Radio Modems are configurable to support several advanced networking modes.
