).
Step Two: Add the carrier file. The carrier can be MP3, MP4, PDF, JPG, smoke to exe file can be used to store secret files. Click the Add button at the bottom left of the interface to select multiple carrier files to open. Openpuff will be based on the hidden file size, automatically choose the number of the rumor to the
line, and exclusive bandwidth. Circuit Switching Mode: the connection between user devices is established on demand. When the user needs to send data, the carrier switch connects a physical data transmission path between the caller and the called end. When the user does not send data, the carrier switch disconnects the transmission path. Group switch: This is an exchange method based on the carrier's group

quantity= goods in the warehouse class, and the handling methods in the Worker class Movein (int i) and moveout (int i).
The problem: Through the test found that each worker to carry the operation will be a new warehouse, that is, the goods are not placed in the same warehouse, this is how it? (Look at the code below)

[Root@xiaoluo ~]# chkconfig--list | grep networkmanager
NetworkManager 0:off 1:off 2:off 3:off 4:off 5:off 6:off
After stopping the NetworkManager service we can use IP alias technology to configure multiple IP addresses, here we use the IP command, the command syntax format is as follows:
IP addr Add 172.25.215.40/24 dev Etho label eth0:0
Behind the eth0:0 says, we add an IP alias to eth0 this network card, the latter 0 means a name, the second alias
Domestic 4G standard Td-lte seems to be vigorously improve the speed, by the Shenzhen Mobile launched a test, td-lte "enhanced version" technology in the 4G network transmission rate is increased by one times, field test conditions of mobile 4G download peak rate of up to 218m/seconds, is now available in mobile version Glory 6 and other mobile phone models Experience up to twice times faster than 4G. Field test for peak rate up to 218m/sHuaqiang North, Bantian, Luohu and other Shenzhen differe
1: What are the characteristics of TDD technology?
L Time Division Duplex (TDD): distinguishes uplink and downlink based on different time slots
P advantages
N when the upstream and downstream services are asymmetrical, different quantities of time slots can be flexibly allocated to the upstream and downstream operations, resulting in high spectrum efficiency.
N uplink and downlink use the same frequency carrier, which facilitates the introduction of

network consists of SDH/SONET devices, and the combination of GMPLS/ASON and SDH/SONET greatly improves the reliability of optical networks, and has been widely used.
Transmission technology is evolving rapidly. With the increasing variety of services, the bandwidth consumed by grouping services is increasing, and the Business granularity is also growing. In the age of group dominance, everyone's focus is on Carrier Ethernet and wavelength division,

Recently, due to project requirements, a simple solution is to use the WebService provided by Sina to receive and send short messages and query data on the Internet.
There are several good articles. Please refer to them for reference:
A good blog in http://blog.joycode.com/joy/posts/16939.aspx
In the previous article, I mentioned that in my Process Monitoring System, I applied the Web service that sent text messages from Sina to get everyone's response. Many people are very interested in this.
It is used as an infrared receiver through a common infrared emission tube. If you see the original signal with an infrared carrier through the oscilloscope, what the decoder needs to do is:
1. Calculate the carrier frequency;
2. Copy a complete infrared data packet;
3. Identify the re-transmission mode in infrared data packets (re-send data packets/send fixed repeate waveforms /......);
4. Special format r

MSComm controls are very convenient for serial programming. programmers do not have to spend time learning more complex API functions and can use them in VC, VB, Delphi, and other languages. Microsoft Communications Control (MSComm) is an ActiveX control provided by Microsoft to simplify serial communication programming in windows. It provides an easy way f
not the real distance between the user and the satellite, but a pseudo distance (PR): When the GPS satellite works normally, the system constantly uses a pseudo-random code (pseudo code) consisting of 1 and 0 binary code elements to send navigation messages. There are two types of pseudo-code used by the GPS system: Civil c/a code and military P (y) code. The C/A code frequency is 1.023 MHz, and the repetition period is one millisecond. The Code interval is 1 microsecond, equivalent to 300 m. T
What are the LTE downlink reference signals and upstream reference signals?In R9, the downlink defines four reference signals, respectively, for the cell-specific reference signal (C-RS), the user-specific reference signal (UE-RS, also known as Dm-rs), MBSFN reference signal, position reference signal (P-RS).In R10, the downlink defines five reference signals, namely, the cell-specific reference signal (C-RS), the user-specific reference signal (UE-RS, also known as Dm-rs), the MBSFN reference s
