Point to Point In Point to Multi Point or Multi Point to Point network all communications are controlled by the master Each slave end serial device must have an address programmed into it Each com mand from the master contains an address and all slaves hear each command Only the slave with the matching address will respond Typically slaves are polled in sequential fashion Note that the response time will increase as the number of slaves increases This type of network can be optimized by polling slaves that require a faster response time more frequently than other slaves Point to Muttipoint 8 3 Adding Repeaters Store and Forward When radio is configured as repeater it utilizes Store and Forward to transmit the data beyond the range single radio An important note is that all radios in the network must know that there are repeaters so that if they hear weak signal direct from the master radio repeated by the repeater they do not respond twice This is Group setting see Section 4 for more information 8 1 RAD ISM 900 Radio Series Section 8 System Architecture repeater will slow the response time There is no limit of the number of repeaters that can be used in system However more repeaters will further slow the response time With one repeater network slaves that pass data through that repeater will have double the re

Probability of Intercept LPI Two SS techniques commonly used today are Frequency Hopping and Direct Sequence Frequency hopping systems employ narrow band channel switching scheme whereby the transmitter moves rapidly among pre determined set of frequencies The time spent one frequency is only fraction of second The receiving station s are programmed to follow the transmitter step with the hopping pattern Direct sequence radios spread their RF energy across a wide chunk of spectrum rather than hopping among discrete channels The amount of energy on any frequency is extremely low but when the signal is de spread at the receiving end through a compression a usable signal results Direct sequence systems are commonly used in short range LAN applica tions 1 5 1 License free advantage A major advantage of Spread Spectrum is that many users can occupy a given band at the same time without causing serious interference to one another This has promised many countries to permit license free operation of SS systems with certain restrictions In the United States for example no license is required for 902 928 MHz SS operation with a maximum transmitter power of 1 watt 30 dBm and an antenna system gain that limits effective radiated power ERP to 36 dBm or less This means that for a one 1 watt transmit ter an antenna system with 6 dB of gain may be used When antenna systems of greater gai
