Mobile Wireless Modem
enhances data encryption through the Temporal Key Integrity Protocol
(TKIP), which replaces WEP's 40-bit or 128-bit encryption key that must
be manually entered on wireless access points and devices and does not
change. TKIP is a 128-bit per-packet key, meaning that it dynamically
generates a new key for each packet and thus prevents collisions. WPA
also includes a message integrity check feature to ensure that data
packets have not been tampered with. The later WPA2 indicates
compliance with the full IEEE 802.11i standard and uses Advanced
Encryption Standards (AES) encryption protocol that guarantees better
security.
WIFI
: "Wi-Fi", short for Wireless Fidelity, is a trademark of the Wi-Fi
Alliance and the brand name for products using the IEEE 802.11 family
of standards. It connects computers and other network devices via
wireless radio instead of cables.
AP: A wireless access point (AP) is a device that converts wired signal
into wireless signal, meaning that it allows wireless devices to connect
to a wired network using Wi-Fi. It usually connects to a router via a
cable to relay data between the wireless and wired devices on the
network.
