Three solutions to network CNC machines are introduced. Advantages and disadvantages are compared. Wireless network solution supports a wider range of CNC communications but easy be disturbed. Single port server solution ensure stable signal but hardware cost is high. TCP/IP solution is stable and reliability while most low-end CNCs do not have Ethernet ports. CNC quantity, port type, distance between CNCs and computers, required speed and cost should be considered to choose right solutions.

The radio spectrum is limited, but in urban and rural areas some bands of radio spectrum are idle in most of the time. Some bands of radio spectrum are occupied occasionally. On the other hand, some bands are excessively used. This paper propsed an adaptive time division Duplex (ATDD) technology to effectively improve the transmission delay in the large range ,such as the rural network in 802.22 network.

This report deals with an effort to begin the process of effectively identifying children in rural areas with speech and language problems using existing school personnel. A two-day competency-based workshop for the purpose of training aides to conduct a large-scale screening of speech and language problems in elementary-school-age children is described. Training strategies, implementation, and evaluation procedures are discussed.
