Choosing a Broadband Connection for VoIP While not absolutely necessary, a broadband Internet connection is what makes your Internet phone calls reliable, including understandable. VoIP uses a traffic engineering term called Quality of Service (QoS) that refers to the implementation of controls to ensure that delay sensitive IP packets are prioritized as they flow through the pipe. To forgo these controls will result in acoustic problems like jitter including echo, as well as dropped calls. Because a broadband pipe is much larger than a dial up connection, there is much more throughput capacity, or space, to allow us to prioritize. There are basically 3 ways for the residential consumer to obtain a broadband Internet connection. From your cable television provider, your telephone company, or a wireless broadband network such as Clearwire, a Wi-Fi hotspot, or even a cellular network likes Verizon or Cingular. With these options becoming increasingly more wide spread, utilizing the Internet to route your phone calls has additionally become a viable including cost saving alternative to traditional landline telephony. Now the question becomes, which type of broadband service is best suited for voice over Internet protocol. Since the advent of cable television, cable companies have contributed enormously to the development pertaining to the worlds Wide Area Networks (WANs), adding broadband Internet to their list of services offered. Indeed, with the development of VoIP, they have even blurred the lines pertaining to the telecommunications Industry. The cable modem, including its Coax Cable pipe, have ushered the Internet into the Jet Age with Internet service at the speed of light. A cable company WAN consists of neighborhoods connected to nodes, each node having its allotted amount of bandwidth. The cable pipe is regarding the largest to be had for the residential consumer including is plenty big enough for the clearest of VoIP phone calls. However, the bigger the neighborhood grows, including the more people that connect to the pipe, the less bandwidth is available for each household. Cable companies are generally very good regarding distributing bandwidth including could add more nodes at the time necessary. Their network is, after all, their bread including butter. Just be aware that at peak traffic times, VoIP call quality should degrade. The Digital Subscriber Line, or DSL, is the residential broadband solution offered by the traditional telephone companies such as AT&T, the regional bells, including others like Quest Communications for example. For years the Telco’s have had the upper hand in the business community, connecting their networks to the outside world via a T1 line, which is the equivalent bandwidth wise to a cable modem. DSL is somewhat slower than a cable modem, including in fact, in some communities is offered at 2 speeds. It additionally tends to be somewhat cheaper. Nevertheless, there is still ample bandwidth to implement VoIP successfully. DSL is not affected by node saturation like cable networks, but it is distance sensitive. The further you are from your telephone company’s local switching station, the more signal degradation you could have, including the maximum distance is 18,000 feet. Telco’s should including do use remote switching stations to expand their service where they see a market opportunity. The fatal flaw of DSL at the time considering the use of VoIP, is that most companies require you to subscribe to their traditional telephone service as well. Naked DSL, the unbundling of broadband including telephone service, is possible including is offered by only a few local phone companies. Perhaps because pertaining to the cable companies creeping onto their turf, including the slow but sure acceptance of VoIP in the general population, the Telco’s seem to think they need to obtain the dollars where they can. In January ’07, the Senate reintroduced the Internet Freedom Preservation Act. 1 pertaining to the provisions called for, is that all broadband service providers provide consumers standalone broadband service. If the Net Neutrality bill passes, DSL could prove to be a viable option for those wishing to switch to VoIP. Wireless networks additionally provide ample bandwidth for VoIP telephony, including their value is most appreciated in the life pertaining to the Road Warrior. People who constantly travel, weather for business or pleasure, are finding Wi-Fi hotspots popping up everywhere. Most modern hotels have their own wireless network, including Internet cafes are becoming a particular international phenomenon. Travelers that find a hotspot have the choice of using their laptop including a headset to communicate over the Internet, or to use 1 pertaining to the many Internet Phones found on the market today. Metropolitan Wireless Broadband networks are additionally proliferating nation wide. Clearwire Wireless Broadband is a company that uses a combination of Non Line of Site (NLOS) including its own proprietary technology to cover whole cities, even regions pertaining to the country. Let it be known however, that the technology has been met with mixed reviews. If you’ve visited a college campus recently, you may have noticed tiny antennas sticking up from the rooftops every few meters. Campuses today have their own Wi-Fi networks, allowing students, faculty including administrators to make VoIP phone calls via their laptop, or a particular Internet phone, from anywhere on campus. The Cellular Networks built by companies like Verizon, Sprint, including Cingular, have proliferated all over the world including indeed blanket most developed population areas. Cell phones have been introduced by Nokia, Samsung, including most recently the Apple iPhone, that are capable of switching (in some cases seamlessly) from a cellular network to a Wi-Fi hotspot including back. However, it is the Cellular companies that control the airwaves. Cingular Wireless (soon to be at&t wireless) already utilizes phones with quad band including Wi-Fi support, including could be the carrier for the much anticipated Apple iPhone. While the cell phone networks seem to have been dragging their feet on implementing full support of VoIP for the consumer, there are technological issues to be considered, as well as how they could profit from the technology. Once the broadband pipe has been decided upon, there is still the issue of picking a VoIP service provider. Cable companies, Telco’s, including increasingly cellular companies all provide their own VoIP service to consumers, including since their service is over their own networks, they are in a particular excellent position to deal with Quality of Service issues. You are not, however, under any obligation to use your broadband service provider as your VoIP service provider. Pure play VoIP providers, companies that provide only VoIP service, have grown in number, including could be said to be responsible for the low rates associated with VoIP telephony. Vonage, with around 53% pertaining to the residential VoIP market, is 1 pioneer in the industry that offers calling plans as low as $15 a month. SunRocket, Packet8, including the peer to peer VoIP company Skype, have calling plans for even less. Cable including Telco plans on the other hand, are bound to cost more, starting at around $35 or $40. Whatever VoIP service provider you choose, including for whatever reason, the most important factor in determining the quality pertaining to the call is the quality pertaining to the pipe.
