The AirCard 555 Wireless AirCard is Sierra's first dual band PC card (PCMCIA style) that complies with the 3G wireless network standard. This 1xRTT (radio transmission technology) interface uses Lucent's Flexent cdma2000 3G wireless technology and enables high-speed Internet/Intranet wireless access from laptops, as well as handheld computers.
Verizon Wireless has recently created their Express Network that uses the low power AC555 to offer reliable 40 to 60 kbps (144 kbps peak) Internet connectivity to mobile business customers. This service is currently available in:
Norfolk, VirginiaWashington, D.C.Baltimore, MarylandPhiladelphia, PennsylvaniaNew York up to Boston, MassachusettsPortland, MaineSilicon Valley in CaliforniaSan Francisco Bay Area, CaliforniaSalt Lake City, Utah (for Olympics)
Because the Sierra AC555 is both 1xRTT and IS95A compatible, it is compatible with the Verizon Wireless CDMA (IS95A) network, which can provide ubiquitous coverage across the entire Verizon Wireless digital network. The cdma2000 1xRTT specification is an international 3G standard that has evolved from today's commercially successful CDMA (Code Division Multiple Access) networks.
Users are able to add voice and SMS (short messaging service) capabilities to their computing devices using the Sierra Wireless AC55.
