The working instruction of Cell Phone Jammers needs to be revised

The working instruction of this kind of Cell Phone Jammers has the second version.
Mobile QQ "is a mobile terminal designed specifically for interactive chat, now more used in mobile phones and PDA. Mobile QQ change in the use of mobile phones in a single cell phone text messages on mobile communication, the messaging capabilities to the Internet, opening the service allows mobile phone users via SMS or WAP function of QQ users with the Internet for chat text messages to PC to phone, phone to the PC's instant messaging. "QQ Chinese body" service body of the Shanghai Information Technology Co., Ltd. China, Shenzhen Tencent Computer System Co., Ltd. through the mobile communication operator's GSM SMS system to send a Sports Short Message Service. "QQ Chinese body" service implementation, you can make the mobile phone users receive a short message body from the China network's sports news, reviews and other news. The working instruction of Cell Phone Jammers needs to be revised.
HE means "high efficiency" (high efficiency). AAC HE-AAC with SBR technology mix. SBR stands for Spectral Band Replication (band replication). SBR is the key to the shed to provide full-bandwidth low bit encoding and does not produce unwanted signals arising. Traditional audio coding at low code that shed means less bandwidth and reduce the sampling rate (see MP3 FAQ # 7) or produce unpleasant noise signal. SBR solution to the problem is to allow the core code to encode low-frequency signal, and SBR decoder low frequency signal generated by analyzing high-frequency signals, and some remain in the bit stream of the guiding signal (usually stream low, ~ 2 kbps).
Currently marketed liquid lithium-ion (LiB) over-charging the battery in the case, and therefore likely to cause safety valve ruptured fire situation, it is very dangerous, so necessary to ensure that the installation of the battery protection IC circuit does not occur over charge of the situation. The polymer lithium-ion batteries, this type of battery is relatively liquid lithium-ion battery has good resistance to charge and discharge characteristics, so outside unprotected IC circuit requirements can be relaxed. In addition, in charge, the polymer lithium-ion battery can be charged using constant current IC with Li-ion secondary battery used in CCCV (Constant Currert-Constant Voltage) charging time required for comparison, can shorten the waiting time for many. 
If the Bluetooth-enabled mobile phone with a Bluetooth headset with a Bluetooth headset must support two protocols: Headset profile (Headset) and HandsFree Profile (Hands-free). Slightly before the establishment of the network, all devices in the ready state. In this state, the device is not connected once every 1.28s monitor news, equipment, once awakened, in the pre-set frequency hopping on 32 monitoring information. The number of frequency hopping vary by region, but the 32 hopping frequencies used by most countries. Initialized by the master device connection process. If a device's address is known, on the use of pages of information (Page message) to establish a connection; If the address is unknown, followed by pages of information on the use of query information (Inquiry message) to establish a connection. In a piconet, no data transmission equipment to the energy conservation condition. From the master device can be set to maintain the way, this time, only the internal timer work; can also request from the device into hold mode.
