Voice over IP in Wireless Heterogeneous Networks
Voice over IP in Wireless Heterogeneous Networks: Signaling, Mobility and Security (Signals and Communication Technology)
The requirements for good quality VoIP communications are difficult to achieve in a time-varying environment due to channel errors and traffic congestion and across different systems. The provision of VoIP in wireless heterogeneous networks requires a set of time-efficient control mechanisms to support a VoIP session with acceptable quality. The focus of Voice over IP in Wireless Heterogeneous Networks is on mechanisms that affect the VoIP user satisfaction while not explicitly involved in the media session. This relates to the extra delays introduced by the security and the signaling protocols used to set up an authorized VoIP session and to the disruption caused by the user mobility during the session. Voice over IP in Wireless Heterogeneous Networks thus investigates and proposes cross-layer techniques for realizing time-efficient control mechanisms for VoIP: signaling, mobility and security.

Answer by Larry W
much easier to get the $ 6 usb wireless dongle for your laptop. Micro Center has them online, I picked up one at Walmart for a few $ $ more.
I stayed at lots of motels that provided free internet, it worked great.
good luck!

Answer by Voip Guy
I use VOIPO with cable and a wireless router. It works like this… The internet cable comes into the cable modem. The network cable comes out of the modem into the VOIPO device. The network cable comes out of the VOIPO device into my wireless router. I can use internet anywhere in the house like normal. Then a phone cable plugs into the VOIPO device and plugs into a wireless phone base. Now I can use my wireless phone anywhere in the house too, but all calls are VOIP. Very cool.
Here’s some information and a discount on VOIPO.
