| Equip your computer or handheld for wireless WAN access |
|
| These tips make accessing your company network from outside your office easier |
Step 1: Set up VPN tunnelling for corporate resources |
|
|
Typically your company's key network and e-mail resources are not available automatically to remote users. Make your intranet, file server, internal databases and other networked tools accessible by setting up a simple virtual private network (VPN). Log into your VPN each time you want to connect to your company LAN.
|
|
Step 2: Deliver wireless entry through your VPN |
|
|
An existing VPN for telecommuters can be leveraged for your wireless WAN access. The accessible resources are the same. You will just be using a wireless connection to get to them instead of a wired connection from a home office.
|
|
Step 3: Ensure secure wireless email transmission |
|
|
How you access your e-mail remotely depends on your current computer and the e-mail system in place. If you are using Microsoft Exchange or Lotus Notes on a notebook or Tablet PC, access to your e-mail is easy and does not require additional software.
Because messages will be travelling over a public network, security is extremely important. The HP wireless e-mail solutions use a robust collection of security schemes to keep your confidential information secure. In the unlikely event that someone intercepts a message, encryption will prevent them from reading the message or any of its attachments.

|
Step 5: Get a cost-effective data roaming plan |
|
|
Because the network is carrying data and not voice communications, you will need a separate data contract. HP's wireless solutions are compatible with the data networks for all major US carriers. As you consider carriers, be sure to consider which carrier provides the best data coverage in your area, the cost of data plans and the roaming agreements each carrier has with other carriers that will supplement your network coverage.
|
|
Step 6: Equip your computer or handheld for wireless WAN access |
|
|
For your notebook PC, iPAQ handheld, Tablet PC, or other mobile computer to communicate with a wireless carrier, you will need a wireless WAN PC card for connectivity. For notebook PCs and Tablet PCs, the wireless WAN card slips into your PC slot just like a Wi-Fi or other wireless card. Most iPAQs however require a PC card expansion pack in addition to the PC card.
The wireless card connects you to a wireless carrier's network that then relays data between your wireless device and the carrier’s gateways and servers. Different wireless carriers use different wireless WAN protocols, so be sure to purchase a wireless WAN card designed to work with your wireless carrier of choice.
