Voice over Wireless Local Area Network
In this week’s report I will be discussing how voice traffic is went over a typical wireless local network. I will also provide information on what the advantages to using a wireless network, the problems associated with using a wireless network and what are the best solutions in overcoming these issues.
A Wireless Voice network or VoWLAN (Voice over WLAN) is how we send digital voice traffic over a wireless broadband network. The type of wireless set up is basically VoIP sent over a WiFi Access Point. Within the industry this type of VoIP set up is call VoWLAN or WiFi VoIP because it uses the standards set for transporting data by the IEEE 802.11 for wireless technology. In order to use this technology we have to use a VoWLAN enabled device; the most common device on the main stream market is the PDA. There are other devices available like the WiFi handset which looks like a cell phone, but it allows voice data packets sent over the network rather than the normal analog voice signal. One of the other major enterprise level devices is not a device at all. It is software based and is loaded on to a workstation or laptop. This type of software is call softphone. It is a virtual phone that routes call through the WLAN AP to the VoIP gateway or IP PBX. There are some advantages and disadvantages to using this type of technology. One of the major advantages is cost a majority of user have WiFi hotspot available in order to stay connected. “A big advantage of wireless VoIP is that IP phones that work on Wi-Fi networks can be used in place of cell phones in many cases. Public 802.11 hotspots are often free or available at a low daily cost. If you're connecting to the Wi-Fi network anyway for Web and e-mail access, there's no additional cost to make VoIP calls other than the cost of your VoIP service, which is usually far less than the cost of cell phone service and may offer free unlimited international calling, something you don't get with most cellular plans.” (Shinder, 2014) With WiFi technology we can now take our VoWLAN enable device anywhere we have service while saving on costs. In relation to advantages there are also disadvantages. This technology is only on the ground floor. It does not have the ability to have a constant connection to the network without a WiFi connection like a regular cellular device. The other major disadvantage is network security. The security of any network is always of the greatest importance. This technology is still vulnerable to outside attacks or intruders. “Security is a vital concern in any wireless deployment, but VoWLAN creates new vulnerabilities. Many currently available handsets support only the WEP security standard, which has proven to be insufficient protection against intruders. Intruders may crack a WEP password simply to make free phone calls at your expense, but the goal may also be to access your corporate data.” (Understanding VoWLAN, 2014)
In closing the important information to know about this technology is that it is just getting started within the industry. It may not work for everyone, but it is already doing wonders in the medical field. Hospitals have already deployed VoWLAN in most major cities. This allows Dr. and nurses to communicate quickly which is a major required in this type of field. This technology is here to stay. Will it remain in its current form, I do not think so. With time just like with WiFi itself it will only get better.

...choice of networks against all electronic threats. Networking hardware is hardware that is used to help work stations connect to a server. Although there are many different kinds of hardware like bridges, network cards the networking hardware that I have chosen to use in within my company’s network are routers, firewalls and switches. Using both routers and firewalls will help protect not only wireless networks but also those networks that use Ethernet cabling. I chose this hardware because I felt that it’s the best hardware to use when keeping my company’s network safe. The software that I have chosen to use is McAfee Anti-virus security software. This software along with the firewall will keep my company’s network safe and secure. Routers along with firewalls are the top network security hardware needed when it comes to keeping a network almost if not all totally secure. The firewall blocks out any unwanted activity as well block hackers from possibly hacking into our networks and stealing important information that pertains to our company and its customers. Along with the router and firewall networking software also plays a major part. The software is what the firewall uses to create its security barrier over the network. McAfee is one of the top manufacturers when it comes to network security. This software enables the use of not only the internet’s firewall but also the ability to detect viruses, anti-spyware upon the network, indicates safety of website upon network by color...

...A local loop is the wired connection from the telephone company’s central office in a local area to its customer’s telephones. It was originally constructed for voice transmission only using analog transmission on a single voice channel. Today, your computer's modem makes the conversion between analog signals and digital signals. With Integrated Services Digital Network or Digital Subscriber Line, the local loop can carry digital signals directly and at a much higher bandwidth than they do for voice only. The central office is an office in a local area which subscribers home and business lines are connected; it has equipment that can switch calls locally or to long distance carriers. Local exchanges, a telephone exchange, are a telecommunications system used in the public switch telephone network. An exchange consists of electrical units, in older systems human operators, which combine telephone subscriber lines or virtual circuits of digital systems to provide telephone calls between subscribers. A telephone exchange is located in a central office, a building used to house the inside plant equipment for possibly several telephone exchanges. POP or point of presence is an access point to the internet; internet service providers generally have multiple POPS. A point of presence is a physical location, either part of the facilities of a telecommunications provider that the ISP rents or a separate location from the telecommunications provider that stores servers, routers, ATM...

It is a type of technology that allows you to express yourself anywhere, anytime toward achieving a greater level of communication. The objective in this paper is to become familiar with the concept of wireless technology. Various topics are covered to include Wireless history, standards, basic principles, regulatory change, and global implications. There was a time when you could easily count all the men in the country who even pretended to know anything about wireless. No one of the few who were working with wireless then, knew whether a set carefully put together would work at all or how far the signals could be heard. Transmissions of a hundred miles or more were hailed as remarkable. Present-day radio listeners are quite prone to think of radio as nothing more than telephonic broadcasting. But before the wireless telephone, came tremendous amounts of hard, sometimes discouraging, but always fascinating and essentially romantic work. Wireless first startled the world’s fair in 1904. At that time there was, of course, no radio public, and the range of wireless was only a few miles. The sending and receiving instruments were unbelievably crude, resembling in no...

...small business network design will of course be a function of the number of users, and the programs that make it up. For most small businesses a peer to peer network with a file server, a router, and a few workstations will be adequate. Your file server can basically be a standard PC that you consider to be your file server. Small Office Network Internet – ISP Wire to office Modem Translates electronic data Router Disperses electronic data Network Adaptor Required for each Computer Wired NIC (network interface card) or Ethernet card Wireless Wireless Adaptor With this configuration you can use the file server as locker for all of your data and set up online backup software to back it up continually. The costs for these services are negligible when considering the frustration and lost time that comes from losing your data. I would like to suggest use static IP addresses to each work station not DHCP. What this means is that the IP address of each machine will remain the same at all times. Removing the variability that is associated with DHCP makes trouble shoots much easier if you have any problems or need to add equipment to the network.  What you will need to get started; cat 5 Ethernet Cable (purchase lengths accordingly) cable/dsl modem (the box the cable supplying the internet plugs into) Router (Wired or Wi-Fi.

Voip as a Bew Trend

...cheaper way to make local and international calls. This new revolution is called Voice over Internet Protocol (VoIP). If I had to put this in plain terms, this technology allows voice traffic to be transmitted over the Internet. VoIP is a new application of Internet Protocols (IP) that enables the conversion of voice communications into data packets and then these packets are transmitted via an IP network such as the Internet. “VoIP services convert your voice into a digital signal that travels over the Internet”. (fcc.gov) Similar to using your analog phone system and going through a Public Switched Telephone Network (PSTN), now you will be using a digital phone and going through the Internet. All you need to get the ball rolling and to be part of this new trend is a decent Internet connection at home and you could say goodbye to that plain old analog telephone line forever. Most cable companies are offering service bundles that include cable television, Internet access and telephone services. These companies are transitioning from the telephone analog system to the VoIP systems. A lot of costumers are switching over to VoIP for the simple reason of saving money. VoIP services usually offer better rates for local and international calls compare to the traditional telephone company rates. VoIP is the technology that makes it possible to have a telephone conversation over the Internet or a dedicated Internet Protocol network instead of dedicated voice transmission lines. This...
