Regarding WWAN Service Providers
It is important to understand that not all WWAN service providers operate in the
same way or support all the same feature sets. Because of this, there exists
some inherent "service provider-specific" variances in service area and more
importantly, in supported features. Along with feature limitations may also come
certain restrictions such as bandwidth constraints and networking limitations.
Before purchasing a WWAN PC card and service plan, check to make sure that
the WWAN service provider offers support for the features you need.
Before committing to a service contract with a WWAN service provider, it may
be helpful to ask these questions:
• What types of traffic are allowed over the WWAN network?
• Do they offer "static" or "dynamic" IP addressing?
• Are there any inbound connection limitations?
• Are single or multiple hosts allowed?
• Do they support VPN traffic?
• What are the data transfer limits (inbound and outbound)?
• What are common data transfer speeds and how much of the
coverage area supports 3G or faster technology?
