1 I Regulatory Notice z To comply with the relevant FCC regulations, changes or modifications are not expressly allowed as it will arbitrarily uses or alters the radio frequency signals in violation, which may void the user’s authority to operate this equipment. z Low power radio frequency device must be professionally installed. z For safety reasons, the working condition must not alters the RF signal. When installing this equipment, observe the following precautions to minimize the danger of personnel injury: 1. Antenna used for this device must be fix-mounted on permanent outdoor structures to provide 5 meters or more separation from all persons during device operation to comply with FCC RF exposure requirements. 2. Always disconnect all power connections before installing antenna. I Warning z If low power RF devices interference endangers the functioning of a radio navigation service or of other safety maintenance services or seriously degrades, obstructs, or repeatedly interrupts a legitimate radio communication service, it is required to terminate the operation and take steps to improve so as to eliminate future interference. z Low power RF devices MUST tolerate all legitimate ISM band interferences. z The above legal telecommunications are based on the Telecommunications Act of Radio Telecommunication Equipment.

E1 Spread Spectrum Radios 5-17 Random noise was first regarded as an element that damages the quality and quantity of communicative signals in communication technology. The random noise in signal channels often distorts the simulated signal produced or bit error to appear upon the demodulation of digital signals. At the same time, it is also one of the elements that limit the channel capacity. Consequently, human’s early attempt was to remove or lessen all the pseudo noise in the communication system. Nonetheless, some of them decided to obtain all these pseudo noise. For example, communicative equipments or systems testing in laboratory require an addition of certain noise. So it is necessary to produce/obtain noise here. In the late 1940s, along with the communication theory, Claude Shannon pointed out that under certain conditions, for the most effective communications, must adopt signals containing the statistical property of white noise. Besides, in order to achieve communications of high reliability and privacy, we must use random noise. However, the biggest difficulty faced in using random noise is that it is not easy to repeatedly produced and processed. Until the 60’s, the pseudo random noise came about and solve all these problems. Pseudo random noise poses statistical property similar to random noise. At the same time, it can be repeatedly produced and processed easily. It has increasingly been extensively use practically because it poses the advantages of random noise and none of its disadvantages. In today’s world, it has been extensively used in digital circuit produced periodic series (after filtering). In the future, this shall be called the periodic series or the random series. Pseudo random sequences are generated using a binary shift register with taps that are modulo-2 added together and fed back to the register's input. The name commonly used for this simple circuit is linear feedback shift register, or LFSR. Another type is known as the Non-Linear Feedback Shift Registers. Only certain combinations of feedback taps will result in maximal-length sequences, called m-sequences. These are the longest sequences possible given a specific shift register size, and they have many desirable properties. If the register size is m stages, the length of the m-sequence will be 2m-1. Nowadays, the equipments used are mostly PRBS of m-sequence: x15 + x + 1, 100003. C4.Ber-Clear Clear all accumulated bit error on starting the BER transmission test. Press the OK button.
