not use the at prefix or carriage return. Enter this command to make the modem repeat the last command, which is most useful for the phone number that repeatedly calls the busy line.
FN: default factory value. If the modem has a default factory value, this command (where n = 0 or 1) returns all parameters to the selected set with the default factory value, but not all modems.

The front-end directly involved opentripplaner, an open-source project with powerful functions. Here is a brief introduction:
Opentripplanner (OTP) provides an open-source platform for multi-mode route planning. You can use the built-in Web interface of OTP to walk together,
Bicycles and public transport are used to query routes. OTP also provides APIs called by third-party programs.

transmission rate is equal to twice times of the bandwidth to ensure the non-interference between the front and rear code elements.
Rmax (maximum information transfer rate) = B*2
B: Bandwidth
B. Noise (bandwidth and signal-to-noise ratio)
Calculate with Shannon formula
C: (channel capacity) channel error-free maximum information transfer rate, that is, rmax (information transfer rate maximum)

When using object pointers, C ++ often needs to consider the following issues: pointer initialization, object creation, and release. This will undoubtedly increase the burden on programmers. programmers should not only consider the business logic, but also always learn when to create and release pointers. Is there any way to solve this problem? The answer is yes. Here is an example to illustrate this mode.
Suppose we want to simulate an aircraft carrier
, namely 1.4mhz,3mhz,5mhz,10mhz,15mhz,20mhz. The lower bandwidth of 1.4MHz and 3MHz allows for easy CDMA2000 use of the spectrum to be migrated to LTE while helping to facilitate the migration of GSM and TD-SCDMA to LTE. The purpose of a variety of bandwidth is to adapt to different frequency of the use of the scene, such as the frequency of the available bandwidth of less than 10MHz, then the LTE system can be configured to 5MHz use.not all channel bandwidth can be used as a resource for transm
IntroductionEthernet is the most successful LAN (local area Networking) technology in the last 30 years. 1. First widely used LAN technology (a widely used LAN technology) 2. Kept up and speed race:10 mbps–100 Gbps 3. connectionless: No handshaking between sending and receiving NICs (network Interface card, network card) No connection is established. 4. unreliable: receiving NIC doesn ' t send ACKs or nacks to sending NIC Not reliable.

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
