Dual-card:Two long phone cards are available for mobile phones. Dual waiting:Dual-network dual-number online at the same time. From a global perspective, the coexistence of the Internet and the Internet is a reality, and the coexistence of 2G and 3G is inevitable. Therefore, the existence of dual-mode or multi-mode mobile phones is inevitable, the key to the success of dual-mode or multi-mode is that you do not need to switch over or be online at the same time. Dual-mode Dual-Wait implementati

Android operator and Network Type Analysis For some requirements, you need to obtain the carrier and network type, and analyze the carrier and network type. First, we will throw some nonsense definitions: GSM: The Global System of Mobile communication is a well-known GSM, the most widely used Mobile phone standard. CDMA: Code Division Multiple Access (CDMA) is a new and mature wireless communication techno

The current attack on smartphones is focused on software running on the application processor, which is the way to break the phone's baseband processor and cause remote code execution attacks on the baseband stack. This is a new field, but domestic research in this area is almost no, sent to Freebuf unexpectedly did not audit pass. (need basic communication technology GSM,openbts and so on basis)from the German security company. Comsecuris Company Gen

the most promising cellular location technology in GSM system, but it needs to change the soft and hard structure of terminal, so it is not widely used at present. (Computer science) (3) According to the different parameters of positioning, can be divided into field strength measurement (SSOA), enhanced field strength measurement method/Multipath Fingerprint method (essoa/fingerprint), Arrival angle Measurement (AOA), Arrival/Time difference measure

WAP is the standard of wireless internet, developed by several large vendors, it defines a layered, scalable architecture that provides a comprehensive solution for the wireless internet. One of the principles of WAP Protocol development is to be independent of the air interface, the so-called independent of the air interface refers to the WAP application can run on a variety of wireless hosting network, such as TDMA, CDMA, GSM, GPRS, SMS and so on.

With the continuous maturation of communication technology and the increasing demand of users for communication quality, the existing GSM network will inevitably evolve to W-CDMA (wideband Code Division Multiple Access), which is estimated to take about 2-3 years, and the main wireless network equipment suppliers will be the earliest It will be 2002 years before a commercially available W-CDMA system can be provided. But this does not mean that mobile

[Popularity] the difference between WAP, GPRS, and WLAN The General Packet Radio Service (GPRS) is a common group wireless service and a new group data bearer service developed on the existing GSM system. The most fundamental difference between GPRS and GSM systems is that GSM is an electrical switching system, while GPRS is a group switching system. GPRS is pa

The next task is to encapsulate the SMS sending/receiving module. I thought it was very simple, that is, serial communication and AT commands. There are still many gaps with expectation in a few days, in addition to portability considerations, it seems that the timetable will be extended... Below is the GSM at command related to SMS, which is posted here for your convenience.1. Related GSM at commandsThe
