Wireless means different things to different people. For this book, it refers to the radio systems that provide point-to-point, point-to-multipoint, and Earth-space communications over transmission links that propagate outside buildings through the lower atmosphere. Wireless systems are being built that provide data transmission between computers and other devices on one’s own desk. These are part of the wireless world but not the part where, except for interference perhaps, the atmosphere has any influence. The intent of this book is to provide a description of the physical phenomena that can affect propagation through the atmosphere, present sample measurements and statistics, and provide models that system designers can use to calculate their link budgets and estimate the limitations the atmosphere may place on their design.

Telecommunications is today widely understood to mean the electrical means of communicating over a distance. The first form of telecommunications was that of the Telegraph, which was invented quite independently in 1837 by two scientists, Wheatstone and Morse. Telegraphy was on a point-to-point unidirectional basis and relied on trained operators to interpret between the spoken or written word and the special signals sent over the telegraph wire. However, the use of telegraphy did greatly enhance the operations of railways and, of course, the dissemination of news and personal messages between towns.

This a naive implementation of BOOTP/TFTPBOOT, the protocols to use to bootstrap a computer through a TCP/IP network. The goal was to design a small footprint implementation to allow the code to be integrated into a monitor program stored in a ROM/FLASH, the footprint is about 7 KBytes for the test program. This code has not been yet tested in many environment. It should be seen at your starting point to integrate the network boot function to your board.

（1） 實現一個Point類，該類包含表示坐標的兩個int型變量x、y，構造方法Point()和Point(int xx, int yy),返回x值和y值的int getX()和int getY()方法，計算兩點間距離的double distance(Point)方法。其中計算平方根用Math.sqrt()方法。 （2） 實現一個Circle類，該類包含表示圓心的Point型變量center，表示半徑的int radius變量，以及構造方法Circle()、Circle(int xx,int yy,int r)、Circle(Point c,int r)，返回周長和面積的int perimeter()、double area()方法，返回兩個圓是否為同一個圓（返回0）、同心圓（返回1）、相交的圓（返回2）、分離的圓（返回3）、包含的圓（返回4）等關系的int relation(Circle c)等方法。PI值可以用Math.PI常量。 （3） 實現測試上述兩個類的ClassTest類。該類在main方法中分別創建若干個Point對象和Circle對象，并調用相關方法，輸出方法的返回值，驗證其正確性。 （4） 將Point類、Circle類和主類的包名分別調整為p1、p2、p3，并重新運行，驗證是否運行正確。

Abstract: Designers who must interface 1-Wire temperature sensors with Xilinx field-programmable gate arrays(FPGAs) can use this reference design to drive a DS28EA00 1-Wire slave device. The downloadable softwarementioned in this document can also be used as a starting point to connect other 1-Wire slave devices. The systemimplements a 1-Wire master connected to a UART and outputs temperature to a PC from the DS28EA00 temperaturesensor. In addition, high/low alarm outputs are displayed from the DS28EA00 PIO pins using LEDs.
