...Voice Traffic Joseph Stozek DeVry University When thinking about WLAN technology there are many benefits that seem to make it a great and upcoming aspect in the networking world. Providing support for voice communications, telephone traffic is a big benefit of that. The WLAN is also a great benefit because it supports both data and voice traffic, making it less money because the two are combined. They offer all types of new applications and different types as well. Wireless PDA’s are a type of advantage to the WLAN as well. They make accessing voice and data much easier to access and more viable to use (Geier, 2003). When looking into disadvantages there are a few of those as well. They were not designed for streaming media, and will cause congestion in the network. Another big problem would be voice mobility. Since most phone users are much better at being more mobile than data users, it causes a problem as well. Most people have an easier chance when they are moving around talking, then they are at texting. It is so much easier sometimes to talk, than it is to type. A person can easily tell each other what is on there mind in a few minutes, when it might take a few more minutes to try and type it out. Time can easily be saved in just talking on the phone. Security over the WLAN would be a big disadvantage as well. So many people try and hack people over their wireless networks all the time. If you do nothing about making...

These include using Frame-relay based WANs, MPLS, private lines, or simply just the internet. In this paper I will discuss the problems which can be encountered when using the internet to carry your VoIP service, and I will also outline the techniques you can use to overcome these problems. I will start off by explaining the problems that you can encounter when using the internet to carry your VoIP service. The first drawback of using the internet to carry your VoIP service is bandwidth or poor internet connection. This is a problem because the service essentially rides along on top of TCP/IP which doesn’t contain any way of specifying a bandwidth requirement; this is what leads to packet loss. Once enough packet loss has occurred, it makes it impossible to hold a conversation because the other end isn’t getting the message. This then leads the caller or receiver having to wait until the internet traffic reduces in order to re-establish the connection; this can obviously be very costly for businesses that rely on telecommunications to do business. A way to overcome this problem is by allowing an outside business, person, vendor, etc. to access your organization’s extranet. An extranet according to Techopedia “is a controlled private network allowing customers, partners, vendors, suppliers and other...
