WI-FI
WIFI STANDS FOR WIRELESS FIDELITY AND ENCOMPASSES A WORLDWIDE (DEFACTO) STANDARD, WHICH ALLOWS HIGH-SPEED WIRELESS INTERNET TRANSMITTED VIA RADIO WAVES WITH SPEEDS OF MBPS, RATHER THAN KBPS.
THE SO-CALLED HOTSPOT OR HUB OR WLAN ACCESS POINT SENDS OUT A WIRELESS SIGNAL TO ALLOWS WIRELESS DEVICES ACCESS WITHIN A CIRCLE OF 100 METER.
ISSUES (I):
 SECURITY
 SERVICES AND APPLICATIONS/HOTSPOTS
 EXPLOITATION/ACCESS PRICES
 HOW LIBRARIES AND INFORMATION PROVIDERS ARE RESPONDING TO THIS NEW OPPORTUNITIES (CONTENT LICENSING, ACCESS AND ACCESS CONTROL, CHARGING, AUTHENTICATION)
 Issues (II)
 BARRIERS FOR EXPLOITATION (II)
- IP-ADDRESSES FOR GRPS ARE DOMAIN SPECIFIC, SO WHEN A USER GOES FROM GRPS TO WIFI ACCESS THE IP-ADDRESS HAS TO BE CONVERTED INTO AN IP-ADDRESS FOR WIFI ACCESS, WHICH MEANS AN EXTRA LOG-IN AND LOSS OF THE PRESENT SESSION
- LACK OF “UNIFIED ROAMING”: TRANSFERRING AN EXISTING CONNECTION TO ANOTHER NETWORK/OPERATOR
- LACK OF VISIBILITY AND RECOGNITION AT PUBLIC PLACES (NO ICON YET) AND
A KILLER APPLICATION FOR THE PROLIFERATION OF WIFI
COULD WELL BE THE COMBINATION OF MOBILE CALLING
AND WIFI ACCESS VIA VOICE-OVER-IP, WHICH ALLOWS
THE AUTOMATIC TRANSFER OF A MOBILE NETWORK TO A
WIFI NETWORK. WIFI CALLING IS CHEAPER THAN MOBILE
CALLING.
