Macsense Connectivity AeroPad Mini user manual Advanced Setting

5.5 Advanced Setting

This page contains configurations for advanced users. Most users will not need to change the settings. These changes affect the wireless performance and operating modes of the AeroPad Mini. Items on this page may help increase wireless performance if set correctly.

Beacon Interval: Sets the period of time in milliseconds that the AeroPad Mini sends out a beacon. The default is 100 milliseconds.

RTS Threshold: This is the size of RTS/CTS packet size. The default is 2432 bytes.

Fragmentation Threshold: Number of bytes used for the fragmentation boundary for directed messages. The default is 2436 bytes.

DTIM Interval: This indicates the interval of the Delivery Traffic Indication Message (DTIM). A DTIM field is a countdown field informing clients of the next window for listening to broadcast and multicast messages. When the access point has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM interval value. Access point clients hear the beacons and awaken to receive the broadcast and multicast messages.

Preamble: Select either a Long or Short Preamble type. The preamble is a sequence of bits transmitted at 1Mbps that allows the PHY circuitry to reach steady-state demodulation and synchronization of bit clock and frame start. Two different preambles and headers are defined: the mandatory supported Long Preamble and header, which interoperates with the 1 Mbit/s and 2 Mbit/s DSSS specification (as described in IEEE Standard 802.11), and an optional Short Preamble and header (as described in IEEE Standard 802.11b). At the receiver, the Preamble and header are processed to aid in demodulation and delivery of the PSDU. The Short Preamble and header may be used to minimize overhead and, thus, maximize the network data throughput. However, the Short Preamble is supported only from the IEEE 802.11b (High- Rate) standard and not from the original IEEE 802.11. That means that stations using Short-Preamble cannot communicate with stations implementing the original version of the protocol.
