cell phone jammer utilizes the very-high frequency

cell phone jammer utilizes the very-high frequency.
The current GSM mobile communications network 9.6K bytes per second transmission speed, GPRS cell phone launched earlier this year has reached 56Kbps transmission speed, up to now is to reach 115Kbps (this rate is twice as common 56Kmodem ideal rate) . GPRS is a packet switching for data transmission, because it is packet switching, and therefore on the utilization of network resources than circuit switching has been greatly improved, and GPRS simultaneously transfer voice and data, and billing can be completely according to statistics generated by traffic. The current carrying circuit-switched WAP (CSD) method, circuit-switched data and voice can not be carried out in accordance with the charging mode is also a long time to charge. cell phone jammer has no interception on the base station.Training of cell phone jammer specific to personnel is unnecessary
In fact WAP and GPRS nature itself can not be compared, the existing content on the WAP GPRS can browse and apply as above, except that the existing GPRS WAP CSD way faster, more convenient, more reasonable fees for of WAP services will be because of network technology to promote greater progress and improvement. In the long run, WAP is now using CSD (Circuit Switched Data) and GSM data services, since WAP GPRS can also be converted to use the GSM network as the new bearer. The weight for then antenna of cell phone jammer is only 100g.
Therefore, GPRS will not replace the WAP, give a vivid example: GPRS CSD, and now the way is the road GSM data services, WAP is the car on the road, WAP is now traveling in two lanes, GPRS improves data transfer speed , is 8 lanes, it can be said to enhance the WAP GPRS service, the same as the existing content on the WAP can be viewed via GPRS and applications. GSM GPRS is developed on the basis of a packet-switched data bearer and transmission, compared with the original GSM, GPRS data services in support of the bearing and has a very distinct advantage: GPRS can be more efficient use of wireless network channel resources, especially for sudden, frequent small flow of data transmission; GPRS support higher data transmission rates, the theoretical peak of 115kbps. The power of cell phone jammer is supplied by the battery.
