What is Wireless WAN (WWAN)? … It is an alternative to traditional wired transport, such as Dial-up, ISDN, DSL and Frame Relay, a truly diverse from of transport that rides across the AT&T Nationwide cellular/wireless network.
Capabilities now include new WWAN data plans which work with a PC Cellular Card to provide wireless connectivity for:
Back-up connectivity - when a landline outage occurs or natural disaster strikes, provides enhanced business continuity by providing truly diverse wireless transport
Primary connectivity for lower bandwidth applications – when it’s impractical or impossible to establish landline connectivity for your network at a given location, i.e vehicles, points of sale, kiosks and ATMs, branch offices or remote monitoring devices

* Video streaming is not permitted under the terms and conditions of standard Data Connect plans. **HSPA refers to markets with HSDPA and HSUPA deployed. Referenced speeds require an HSDPA 3.6Mbps / HSUPA capable device with Receive Diversity and/or Equalizer. AT&T is deploying HSUPA throughout the 3G footprint, HSUPA may not currently be available in all 3G areas. **3G speed claims based on our network tests without compression using 3MB data files. 3G devices not enabled with HSUPA support typical upload speeds of 220-320kbps based on our network tests without compression using 500KB data files for upload.
