The Radio Interface Layer is the name for an interface that was developed especially for the Pocket PC Phone Edition. It is meant to abstract the interface with a phone/modem device. To achieve this it is closely modelled after the GSM AT command interface. Unfortunately the API was not published officially by Microsoft. Instead more high level API s were published that should be sufficient for developers. Again, unfortunately they are not sufficient. For example the API for receiving notification of incoming SMS messages is arranged for exclusively for one application per type of SMS. Apparently this will be improved upon in Pocket PC 2003. Another area is the availablity of a true AT command modem interface to interact with the GSM modem directly, which is also absent.

300 km 传输线和功率补偿仿真 The circuit below represents an equivalent power system feeding a 300 km transmission line. The line is compensated by a shunt inductor at its receiving end. A circuit breaker allows energizing and de-energizing of the line. To simplify matters, only one of the three phases is represented. The parameters shown in the figure are typical of a 735 kV power system.

The iputils package contains ping, a basic networking tool. The ping command sends a series of ICMP protocol ECHO_REQUEST packets to as pecified network host and can tell you if that machine is alive and receiving network traffic.ipv6calc is a small utility which formats and calculates IPv6 addresses in different ways. It extends the existing address detection on IPv6 initscript setup or make life easier in adding reverse IPv6 zones to DNSor using in DNS queries like nslookup -q=ANY ipv6calc -r 3ffe:400:100:f101::1/48`

Program for implementing AES on 8051 based microcontrollers. SDCC is used as the C compiler. Microcontroller used is P89V51RD2. There are 2 programs included. One program will accept string via UART and accept key via a 4x4 keypad and display decrypted text on 16x2 LCD. The other program will accept plaintext from UART and show encrypted text on 16x2 LCD after receiving key from 4x4 membrane keypad. Schematics and screenshots are included.

With the Wireless module, OPNET can model both terrestrial and satellite radio systems. In this tutorial, you will use Modeler and Wireless modeling to create a radio network you will also observe variations in the quality of received signal that results from radio noise at the receiving node in a dynamic network topology.
