The portable piece of cell phone jammer can be concealed in the pocket or purse

Depicted in the various agreements with the phone (UE) also is RF-MAC-RLC-RRC-GMM/SM/SMS the various modules involved in the various agreements in order to complete the task to establish a data channel, which control the level of work . But also the lower half of the left side of the block diagram in Figure 12.2, all the agreements depicted with the phone (UE), which is RF-MAC-RLC-PDCP-IP/PPP involved in the various agreements. and related applications (the Applications), in order to transmit data entities, which is the user level. Next, we analyze the BP part of the smart phone. This kind of portable cell phone jammer is very popular and well received in the market, especially in the European and American market.
In the establishment of a data transmission channel, the control plane need to be addressed, as well as the transmission of data entities, the user level need to be addressed. That is, Figure 12.2 figure, the upper part of the left-most block diagram, with the mobile phone (UE), RF-MAC-RLC-RRC-GMM/SM/SMS five modules covered by the agreement and interact with each other. It also includes the lower half of the block diagram of the left-most involved in the agreement with the phone (UE) the related RF-MAC-RLC-PDCP-IP/PPP-Application, six modules interact. Figure 12.3 depicts the part of the agreement contained in these modules, as well as the relationship between [2,3]. Each module can be vertically divided into a number of layers (Layer), each module only contact with the upper and lower layers of the corresponding module, but not with the other modules in the same layer. A new type of cell phone blocker scrambler will be introduced as follows.
Bottom-up, namely the physical layer RF / PHY (Layer 1), the link layer (Layer 2), including the MAC / RLC / the PDCP / BMC of each module, and network layer (Layer 3), including the RRC and the Network Control / AMR Voice / CS Data / PS Data of each module. At the same time, the bottom-up the entire system has been divided into the access layer (Access a Stratum, AS), and non-access layer (Non-Access a Stratum, NAS). Module is responsible for non-access layer and the core network, such as the Network Control Module (Network Control), which is responsible for phone calls and calls connected (Call Control, CC), in the mobile phone to switch base stations, to maintain the call continuous (Mobility Management, the MM ), and to ensure the normal transmission of data packet (GPRS Mobility Management GMM) and so on. The output power of this kind of portable cell phone jammer is the main concern and focus of the customer.
The access layer of the module is responsible for the wireless network system (RNS) within the local contact, including phone (UE) and base station (Node B) between base stations and base stations, base stations and base station controller (RNC), the local contact. In addition, contact the Iu-CS/Iu-PS/Iu-BC involved in the protocol stack between the base station controller (RNC) and core network. Access layer for non-access layer to provide basic services [4]. Protocol stack is divided into a control plane (Control Plane) and user level (User Plane). Figure 12.2 from top to bottom is divided into two parts, the upper part describes the control plane, the bottom half describes the user level. Figure 12.3 the control level is placed in the left side of the user level on the diagram the right side. Non-access layer, for example, the control plane, including network control (Network Control). This kind of cell phone jammer has the aesthetic appearance and strict and accurate parameter.
Responsible for call control (CC), Mobile Call Management (MM), and packet management (the GMM). User level is responsible for voice and packet entities transmission, corresponding to three functional modules, respectively, is responsible for circuit-switched data transmission module (Circuit Switched Data, and CS Data), packet-switched data transmission module (the Packet Switched Data, PS Data) and responsible for voice transmission, adaptive multi-speed voice coding (AMR Voice). 3 radio interface and channel (Channel) for mobile phone (UE), the physical layer (Layer 1) and link layer (Layer 2) is responsible for how to use the wireless spectrum to transmit data, these two layers of protocol data encoding is called channel [5]. The portable piece of cell phone jammer  can be concealed in the pocket or purse.
