Summary

Here are the key points to remember from this chapter:

• A limited number of national Wi-Fi networks provide hotspots.

• A few of these networks (Boingo, Wayport) are attempting to build Wi-Fi networks from scratch.

• Other networks use the infrastructure of wireless or wireless telecommunications providers. (T-Mobile Hotspot is the leader of these.)

• Boingo is the network with the best roaming policy.

• Pricing is erratic and varies from network to network.

• You can generally purchase one-time access, access by the day, or monthly access.

• Some Wi-Fi network providers allow marked-up pricing; beware of retailers who overcharge for Wi-Fi access.
