an of the radio frequency transmission of several factors
because the radio frequency RF is generated and transmitted by the antenna into the wind, the signal will be numerous factors in the propagation of reflection,
PULSERA BLANCA CON ITALIA, digestion, scattering deflection signal to signal generator, so affect the signal quality and strength.
the following elements will influence the signal perversion
walls, ceilings alternatively floors will preoccupy RF waves so namely the signal strength weakens
coarse plaster walls, carpeting, drooping domes RF waves ambition scatter out apt form strewing
metal,
PULSERA NEGRA CON BANDERA, glass will reflect RF waves
Second, the wireless router and wireless network cards supported by the protocol standards
wireless by immediately have the following standard protocol, the network makeup in the buy of these types of concert that we should pay attention to the mate so as to avoid unnecessary difficulty
802.11a standard data rate of 54Mbit / s access to the actual amount of 23Mbit / s range of 35-120 meters in the role of transmission OFDM
802.11b standard data rate of 11Mbit / s access to the substantial amount of 4.3Mbit / s range of 38-140 meters in the character of transmission DSSS
802.11g standard data rate of 54Mbit / s access to the actual amount of 19Mbit / s range of 38-140 meters in the role of transmission DSSS / OFDM
802.11n standard data rate of 248Mbit / s access to the actual amount of 74Mbit / s range of 70-250 meters in the role of transmission MIMO
* Note 802.11n using a 2 * 2 Antenna
the interpretation of several transmission
OFDM Orthogonal Frequency Division Multiplexing Orthogonal Frequency Division Multiplexing
DSSS Direct Sequence Spread Spectrum Direct Sequence Spread Spectrum
MIMO Multiple Input Multiple Output Multiple Input Multiple Output
These are now used several wireless communication protocol standards, but standard apartments and there are several compatibility issues,
PULSERA BLANCA CON BANDERA USA, so pay attention to one agreement to purchase components between matches. If 802.11g is backward compatible with 802.11b, but the rendition drip to 802.11b standards; 802.11a and 802.11b, 802.11g is not compatible with; 802.11n standard could be down to the premier three matches,
Balance Xtreme, but the performance degradation. So let us purchase the same standard components to make use of wireless network components.
3, WLAN security issues to use
WLAN because of the specifics of wireless transmission can accessible be used approach the same or compatible with the criterion use or theft of additional consumers, so we should be sufficient in the use of consideration to safety issues. Such as 802.11b / g NIC and a trial into roaming,
PULSERA BLANCA CON MEXICO, most WLAN solutions patronize some form of security features, yet most folk do not use this feature.
WLAN security solution should note the retinue
conservation equipment and the access point WLAN to transfer data among the reliability of the data transmission to do with encryption
control who tin way the LAN backward the WLAN access point authentication system
and adding intrusion hindrance system, generally defined as the WLAN at the road in the IPS Intrusion Prevention system
WLAN with WEP, EAP, WPA and WPA2 course these types of protection, WEP static opener, EAP as a dynamic key,
PULSERA AZUL CON LOGO XB, WPA dynamic because every pouch has a hidden key, WPA2 is extra safe dynamic key for every packet. One uncomplicated WEP encryption is easily cracked, it is intended later use in several ways.
WEP Wired Equivalent Privacy Wired Equivalent Privacy
EAP Extensible Authentication Protocol Extensible Authentication Protocol
WPA Wi-Fi Protected Access Wi-Fi Protected Access
encrypted using the encryption means
likewise pay attention to when the equivalence.
friends using the wireless Internet access Please note that these make your wireless network faster and more secure.
