The material test of cell phone jammer cannot be cancelled

In terms of costs, WCDMA because it is the exchange of technology with the sub, so the cost is not to use the network access time calculation, but the amount of consumer data to set. EDGE: EDGE of the English full EnhancedDataratefor GSM Evolution, Chinese meaning is "to improve the data rate of GSM services," which is based on GSM / GPRS network data enhanced mobile communications market highlights, there have been U.S. CingularWireless and AT & TWireless, Chile The TelefonicaMoviles, CSL Hong Kong SAR of China and Thailand opened AIS EDGE-based services. The unit price of cell phone jammer will be lower than that of before.
At the same time, some European mobile operators have begun to show interest in EDGE, which have made it clear that TIM and TeliaSonera will be using EDGE technology. The technology is the ability to use broadband services, can make use of 800,900,1800, 1900MHz band to provide third generation mobile communication network part of the network function, and can greatly improve the current GSM and TDMA/136 to provide standardized services. The technology can provide 384kbps data communication services and wide area around 2Mbps local area data communications services, so as to fully meet future bandwidth requirements of wireless multimedia applications. The retail price has been cut by 20%.
Ericsson's EDGE concept is the first time in 1997 proposed to ETSI, the same year, ETSI approved a feasibility study for EDGE, which later paved the way for the development of EDGE. While still using EDGE GSM carrier bandwidth and time slot structure, but it can also be used for other cellular communication systems. EDGE can be considered to provide a high bit rate, and thus to promote the third generation cellular mobile systems function evolution, effective generic wireless interface technology. On this basis, a unified wireless communications forum (UWCC) evaluated for TDMA/136 of EDGE technology, and in January 1998 approved the technology. The wholesale price of cell phone jammer is much lower than retail price of cell phone jammer .
EDGE from GPRS to provide a third-generation mobile communications transitional program, so that the existing network operators can maximize the use of existing wireless network equipment, third-generation mobile network in advance of commercialization to provide users with personal multimedia communication services. As GDGE is a range of existing second-generation mobile networks and third-generation mobile networks the transition between the technology, some people call it the "second half" technique. EDGE also make full use of the existing GSM resources to protect the investments made on GSM, there are most of the equipment can continue to use EDGE. The customer and manufacturer have achieved the agreement on the wholesale price of mobile phone jammer .
EDGE provides three services: EGPRS service: maximum rate of ≥ 384kbps48kbps/BP; T-ECSD business: transparency enhanced circuit-switched services, the highest rate of ≥ 32kpbs/Bp; NT-ECSD: Enhanced non-transparent circuit-switched services, the highest rate ≥ 28.8kbps. TD-SCDMA: TD-SCDMA full name is Time Division-Synchronous Code Division Multiple Access (Time Division Synchronous Code Division Multiple Access technology) is the ITU released the third generation mobile communication interface specification of space, it has been CWTS and 3GPP the full support of the first hundred years of China Telecom a complete communication technology standards, is a fungible UTRA-FDD program, is a CDMA, TDMA, FDMA technology advantages in one, the system capacity, spectrum efficiency, anti-jamming capability strong mobile communications technology. The customer would like to increase the purchase quantity of cell phone jammer .
