Cell phone jammer has little influence on the area beyond the examination room

Like this with a small 7 can connect to the wireless Internet routing after a (see the attached 2 Step 2) The fifth case is that the wireless LAN to share Internet access using the books of friends, in a small 7WIFI need to connect to the network after turn off the firewall on the computer, or access will be blocked by the firewall and the message "no gateway response". WIFI English stands for Wireless Fidelity (Wi-Fi technology), is an office and home use of short-range wireless technology that technology using 2.4GHz frequency band around, it's biggest advantage is that higher transmission speed, the effective distance is longer, but also with various existing 802.11 DSSS devices compatible. WLAN English Wireless Local Area Network (wireless local area network ) acronym refers to wireless communication technology computer equipment will be connected together to form can communicate with each other and sharing resources of a network system. the nature of the wireless LAN feature is no longer used computer and network communication cable connected, but through wireless connected, so that the network build and more flexible mobile terminal. The power line of energizing    cell phone jammer doesn’t need the centralized wiring.
From the speed comparison, GPRS is a packet switching system, each carrier frequency can provide up to 107kbit / s access rate, access areas are narrow due to the use of mobile phone network, so more slowly, the actual rate influenced by many factors , and 56Kbps Modem only; by the most basic 802.11b standard WLAN up to 11Mbps, is a broadband area, if it is 54M wireless network, the rate will be higher. speed wireless network equipment based on the use of different standards can be achieved speed from 11Mbps to 54Mbps from the more coverage, GPRS is built based on the GSM network, and its effective coverage than a single point of the WLAN AP (the wireless access point) to a large coverage area. WLAN coverage limited, the general civilian wireless network environment around the AP only 20 to 100 meters effective, but with broadband ** Wireless "hot spots" and the installation of more and more devices become increasingly popular support WIFI, WLAN will be more widely use. cell phone jammer has little influence on the area beyond the examination room.
In fact similar to the phone with WIFI Internet access with a laptop wireless card online with GPRS access methods are fundamentally different, WIFI and GPRS traffic flow to go is different, so no GPRS WIFI Internet traffic accounting. An obvious The contrast is, when the phone is in offline mode or the SIM card can not win can still use GPRS WIFI Internet access Wireless networks transmit power than the average cell phone is much to be weak: the wireless network transmit power of about 60 ~ 70mw, and mobile transmit power of about 200mw or so, and the use of mobile phones generally like the way nor direct contact with the body, generally do not reach the human body to 1mw, basically negligible. People can enjoy fastness and convenience brought by high technology including    cell phone jammer     .
