MaxStream radio modems can "hear" signals that most modems cannot. Receiver sensitivity is a measure of the weakest signal a radio is able to detect and demodulate. Superior RX sensitivity helps overcome many of the challenges inherent to RF communication systems - such as signal attenuation (degradation). MaxStream's research has shown the average receiver sensitivity for modems in the wireless device market is a mere -93 dBm. Because of superior RX sensitivity, MaxStream radio modems (RX sensitivity ranges from -100 dBm to -114 dBm) achieve up to 8 times the range of competing radios. This enables OEMs and integrators to cover more ground with fewer radios.

XStream Interference Immunity™ (XII™) technology is a proprietary hardware and software feature set that allows system designers to create wireless systems that are immune to most RF interferers (cell phones, pagers, other wireless systems, etc.). 

When operating within the 900 MHz and 2.4 GHz frequency bands, cell phones, pagers and other wireless systems can dramatically interfere with wireless links. MaxStream's XII technology provides MaxStream Modems with up to 60 dB of interference blocking. This means that when two MaxStream modems are communicating at long distances and are near sensitivity level signals, interfering signals just 1 MHz away can be 60 dB (1 million times) stronger than the MaxStream signal and only degrade the receiver sensitivity by 3 dB. 

MaxStream products also utilize frequency hopping spread spectrum (FHSS) communication that, by design, delivers additional protection against interference. 

The XII interference-blocking feature ships in all MaxStream data radio modems.

MaxStream Radio Modems handle the complexities of RF communication (including modulation, demodulation, frequency synthesizers, amplifiers, filters, FCC approvals, etc.), so OEMs and integrators can focus on their own data system development. MaxStream has inspired a revolutionary method of synchronizing networked radio modems that does not require the use of master/slave relationships. This technology allows for very robust communications even in the presence of interference and enables flexible network topologies that are not possible with modules coming from other vendors. MaxStream radios require no configuration and provide long range wireless links out-of-box. If advanced configurations are required, the modems are equipped to support advanced functions.

MaxStream Radio Modems uphold the rigorous standards of the FCC (United States), IC (Canada), ETSI (Europe) and many other government agencies worldwide. Devices containing MaxStream Modems automatically inherit the agency approvals secured by MaxStream.

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.

The XTend product family supports the highest encryption standard available: 256-bit AES (Advanced Encryption Standard). The AES algorithm meets Federal Information Processing Standard-197 (FIPS-197).

MaxStream OEM RF modules and stand-alone RF modems price in well below comparable wired and wireless solutions and includes unmatched advanced features and ease-of-use. Aggressive high-volume pricing allows OEMs and integrators to cut network costs without sacrificing data integrity. 

An in-house survey revealed the average list price for 900 MHz frequency hopping spread spectrum OEM modules was a whopping $700. MaxStream lists its high-performance 9XStream™ 900 MHz wireless OEM module at $150 ($74 @ 5k qty.) The survey also revealed the average list price for wireless OEM modules operating at 2.4 GHz was $500. MaxStream lists its 24XStream™ 2.4 GHz OEM RF Module at only $99.

More of today's wireless applications require battery power, so the lower the output power the better. However, low output power compromises the communication range available in most RF solutions. The key to a great RF solution is to find a product that provides long range at low output power. 

MaxStream RF modules are optimized for low power applications and provide excellent communication at short and long range. These modules operate at a variety of power output levels between 1 Watt and 1 milliWatt, allowing custom-designed networks that meet each application's needs. The XBee product family provides power-down modes that reach below 10 µA.
