Sierra Wireless AirCard 555
With the AirCard 555, users will also be able to make voice calls and
send SMS (two-way messaging) messages.
With the dual-band 1X Sierra Wireless AirCard 555, users will experi-
ence the following:

• Faster speeds: up to 86 kb/s, making it more efficient to access
your time-sensitive information.

• Always being connected: allows users to maximize productivity
by becoming dormant when data are not actively being trans-
ferred through their wireless connection, yet still maintains a vir-
tual connection to the network. This will free up resources,
allowing users to multitask by sending or receiving voice calls or
text messages on their device. When users are ready to resume
their data session, they can re-engage the network immediately—
there’s no need to dial in again, and no waiting. Instant-on Bell
Mobility acts as the Internet service provider (ISP). Users can
connect in seconds to the information they need.
The Sierra Wireless AirCard 555 lets users access their information sim-
ply by sliding it into the PC Card slot in their laptop computer or hand-
held device (see Figure 11.4). Coupled with the easy-to-install software
included in the kit, and a Bell Mobility 1X Data plan, the AirCard 555
transforms the device into a complete wireless business solution.
