VoIP has revolutionized the way telecommunication is done. Voice over Internet protocol allows voice packets to be sent over Internet bandwidth enabling cheap communication. There are many companies which offer voice over Internet services and some of the leading ones are Vonage, Skype, Yahoo and Net2Phone. Consumers can access VoIP over Internet connections like broadband and DSL. Satellite Internet is a new technology that has become very popular in recent times and VoIP providers are able to offer services to customers in remote regions using it. It will still take some time until VOIP by satellite is ultimately stabilized and customers can enjoy the full benefits.
Some of the challenges faced by service providers include packet loss, jitters and limited bandwidth. Service providers like Hughes and Skyframes which have their own satellites are teaming up with the VoIP providers to offer voice services to customers. Designing a VoIP network would require details on the bandwidth requirement for VoIP data. Satellite Internet providers are facing challenges on the bandwidth capacity that would be required to offer VoIP services via satellite channels. G.729 (b) encoding with a 40 b payload and header compression would require 10 Kbps of bandwidth. Packet loss is another challenge faced by service providers offering satellite VoIP services. Packet loss causes degradation in voice quality. The protocol used for voice traffic transmission is UDP/IP and if the data packets are corrupted they cannot be retransmitted. TCP/IP protocol allows retransmission of data packets. It is important to maintain very low bit error rates to offer high quality voice services to customers. Jitters are another technology hurdle that is faced by satellite VoIP service providers. It is used to calculate the delays in packet arrivals that happen because of network delay. If this factor is not within acceptable limits the quality of voice becomes poor and the receiver may not be able to enjoy a good conversation. Jitter buffers are used to overcome this hurdle and ensure that there is less delay in the network. Researchers and scientists are working relentlessly to overcome all hurdles that come in way of experiencing a smooth voice call through satellite Internet.
VoIP by satellite is not ideal because of some more factors. Latency factor refers to the time delay in locating the Geo-stationary satellite and the speed of light. There is a delay of 280 msec because of latency factor. Traffic congestion in the network also affects the quality of VoIP service. This can result in voice packets being dropped, delayed or reaching the receiver out of sequence. Compression technology is another parameter for delivering high quality VoIP service. There are two compression technologies that are followed as industry standards. The G.729 codec uses bandwidth of 18Kbps and RTP uses around 10 Kbps per second. If service providers are able to cope with the technological challenges of VoIP over satellite, it will not be long before remote areas of the United States can connect with the rest of the world.

What is communication?
Communication is a reciprocal sharing of information and ideas of written, oral, non-verbal information according to a common set of rules.
“ If you want to drink and drive, take cocacola” is a better way of communicating with drunken drivers and a better way of communicating the message “drunken driving is risky”
In any profession be it engineering, or medical or legal business executive, it is imperative that the professional should be competent in both oral as well as written communication
Effective Communication is the success of any Organization
Effective communication is the secret of any organizational success. The root of problems in any organization is poor communication.
People in any organization spend 75% of their time in an interpersonal situation.
For teachers, especially English Teachers, effective communication is the key to excellence. First of all the class-room environment should have better view of the teacher. It should encourage individual participation.
Ways to improve Communication : To begin with, let us have simple presentations with grammatically correct sentences, in the chosen language.
1.Listening Listening is vital part of communication. Be a good, active listener. Most importantly communication in its highest form extends beyond talking and listening. It includes behavior. Effective communication is dynamic, continuous, irreversible, interactive and a culture of service excellence and mutual understanding.
2. Be an effective listener: Listening is compared to storing vast quantity of potential water in a reservoir of dam. There are ways in which we can improve the art of listening. Listening is an intellectual activity whereas hearing is not so . In listening our brain processes the data received. But hearing is just perceiving the sound.

by How Customer Communications Creates New Factors in a Marketing Communications Plan
In delivering a customer communications management system, there are extra considerations in respect of the development of a marketing communications plan.
The marketing communications plan can provide a clear guideline as to how to execute, the expected costs and the expected return. Customer communications management will increase the ease with which a multi-channel marketing communications strategy can be executed. It will also increase the sophistication with which a company can communicate in a relevant manner with its customers.
In the context of discussing the plan I will use Philip Kotler ‘P’s framework as this is the standard study for virtually all marketers.
First off, lets establish the Four P’s of product marketing in context with customer communications management:
Product – Which products are you looking to promote? Today’s customer communications management platforms mean that you can market more than one product in an individual campaign based upon an individual users profile. Therefore Product Range Selection is an additional component in the customer communications management driven marketing communications plan.
Place – Customer communications management processes give the marketing communications plan complete freedom to choose from a wide range of communications methods. These include voice, Direct Mail, Transactional Mail, Email, Social Media oriented email, social media direct, SMS, mobile and web. Therefore channel flexibility is a key advantage for the marketing communications plan.
Promotion – Specifically what is your promotion and what are the promotion objectives? To garner new customers? To market more to your existing customers? To raise awareness of a product launch? To build brand appeal through a news advisory about your company’s efforts in the community? To raise funds for a charity that your company sponsors? The options are wide and… Continue reading
