About Wi-Fi
Wi-Fi is wireless networking that provides access to local area
networks without using network cabling, and it is faster and has
a greater range than Bluetooth wireless technology. Wi-Fi can
achieve high connection speeds (depending on conditions at any
given location), which easily allows you to share large files or
quickly surf the internet with your phone.
Note: Wireless Fidelity (Wi-Fi) is a WLAN based on the 802.11 protocol,
which transmits and receives in the 2.4 GHz frequency ISM band. The
SGH-i637 supports the 802.11b/g protocol stack.
Note: The SGH-i637 may not be operable with all wireless access points.
Wi-Fi allows you to:
• Access the internet
• Access your corporate network
• Use hotspots provided by hotels or airports while traveling
• Send and receive email quickly
