BREW (Binary Runtime Environment for Wireless) is an application development platform for wireless phones. Qualcomm was the company to set up this standard and it should be noted that although it was used for CDMA cellular phones, today it can be used for GSM, GPRS and UMTS. Essentially BREW allows consumers to download and use applications on their mobile phones. These applications can include chat programs, email, location positioning, games, etc… Developing Applications with BREW Many developers like to create applications using BREW. BREW makes it much simpler to create Read More

Owning a Blackberry enables its owners to do much more than they could ever accomplish with a basic cell phone. However, one of the most popular features that have carried over from basic cell phone to the BlackBerry is the ability to add ring tones. In earlier models adding ring tones to your Blackberry was quite difficult or not available, however today, if you operate a BlackBerry or later model that uses 4.1 operating system, adding MP3 ring tones is quite simple, here are some tips. 1. Start Up Your Read More

UMTS is an abbreviation for Universal Mobile Telecommunications System. It is one of the third-generation (3g) cell phone technologies quickly developing today. UTMS is also referred to as the 3GSM so as to emphasize the coalition between 3G technology and GSM standard. In theory, the UTMS, using W-CDMA, is supposed to be able to transfer up to 14.0 Mbit/s data transfer rates although real uses have shown a transfer rate of 384 Kbit/s to 3.6 Mbit/s with various handsets. However, this speed is still a lot greater than other competing Read More

Video conferencing has become popular over the last decade. Video conferencing is when two or more parties communicate in real time in separate locations with both video and audio signals. Technology Used in Video Conferencing Video conferencing works by using a few different technologies. Some of these technologies are hardware, others technologies involved in the video conferencing process are software related. Here is a list of technologies that are common to a video conference set up. Video Input Video input usually consists of either a video camera or a web Read More

DSN stands for the Defense Switched Network which is a global phone service used by the United States government capable of both non-secure and secure communications. Traditionally, the DSN network has only been used for voice communications, but in the past decade data and video service have been incorporated into the network through Integrated Services Digital Network (ISDN) connections. Secure DSN phone calls are made through the combined use of a Secture Terminal Equipment (STE) or Secure Telephone Units (STUs). Although the U.S. Department of Defense (DoD) is the largest Read More

The 958 and 959 prefixes (NPA-958-XXXX and NPA-959-XXXX) are used as test numbers. 958 numbers are used for most testing, 959 numbers are reserved for inter-exchange carrier testing. 959 numbers can only be reached by being pre-subscribed to that inter-exchange carrier or using an access code (101xxxx-1-NPA-NXX-XXXX). In other words, to dial an AT&T 959-XXXX number, you would dial 1010288-1-NPA-959-XXXX. To dial an MCI 959-XXXX number, you would dial 101022-1-NPA-959-XXXX. Test numbers tend to start at NXX-1000 or NXX-6900.

SS7 (Signaling System 7) is a standard for control signaling in the PSTN (Public Switched Telephone Network. SS7 signaling is done out-of-band, meaning that SS7 signaling messages are transported over a separate data connection. This represents a significant security improvement over earlier systems which used in-band signaling. The first CCS protocol was the Signaling System 6, defined by the ITU-T in 1977. SS 7 replaced the SS6 in 1980. SS6 had certain limitations, since its signal wasn’t amendable to digital systems. Both SS6 and SS7 are called CCS (Common Channel Read More

Millions of people use monitoring systems and devices for several purposes. Monitoring systems and devices have been around for quite some time and are designed to increase the level of security and protection in facilities. Among the technologies that the cell phone industry created, the cell phone interceptor is what experts consider one of the most innovative and valuable. Cell Phone Interceptors Used for Monitoring The cell phone interceptor is one of the latest inventions that the cell phone industry introduced. The primary aim of developing this unit is to Read More

Before activating a new Verizon Wireless cell phone, it is important that you backup your phone numbers. By making the switch from an older phone to a newer one, you'll lose access to the older one.
