VOIP vs Voice for Handheld Phones
The phones we use at your home were possible for a long time prior to internet came into picture. With the use of internet, technology like VoIP may be introduced to change the way we talk on the phone or mobile and contains the ability to completely transform the existing phone system.
Voice over Internet Protocol converts the analog voice by which we meet with digital data, then transmits it over internet towards the desired destination, and does overturn part of converting the digital data returning to sound that this recipient hears. There are three ways where VoIP service can be used today.
The really need for establishing an VoIP service internet phone system is standard net connection. There are too many free VoIP softwares which works extremely well to make internet telephone calls. And here emerges the threat to cellular phone companies and companies.
The strongest argument for VoIP is that it is cheap, and therefore poses a threat to traditional circuit switching systems used by the (cellular) mobile companies as well as the age old Public Switching Telephone Network (PSTN). The rate for voice calls has traditionally been directly proportional to the distance to where the calls are manufactured, with international calls being not affordable even today.
Comparing Internet telephone underneath the same umbrella, it costs next to nothing to make a global call using internet telephony. VoIP service internet phone systems can integrate with added services available on the net,like video conference, message or computer file exchange, conversation conferencing. It can also work with a computer's address book, including any policy details concerning whether others like friends or co-workers is found online plus your customers.
Voice over internet protocol are capable of doing tasks that has to be harder to realize using traditional systems. Incoming calls could be instantly routed to your VoIP phone, irrespective of where you are. Take your voice over ip phone with you on holidays, and wherever a connection for the web is attained, you might be able to receive calls.
There are share of disadvantages for VoIP service too. The traditional switching system, like a closed system, is quite secure against internet telephone. The Quality of Service (QoS) facet of internet telephony is still under consideration. Another drawback would be the difficulty in delivering faxes due to software as well as networking constraints inside majority of home systems. Attempts 're going ahead to resolve this by determining another IP solution that delivering Fax via IP, called the T.38 protocol. Other possible means to fix the drawback is usually to treat fax systems like message switching systems which not one of them live data transmission - for instance delivering a fax as email attachments or remote printout eventually systems may substantially reduce incoming printable fax data or image.
It is witnessed till date that although VoIP service has became popular and more plus more people are curious about having VoIP communications, the revenues with the carriers have still not suffered financially. The defense by carriers for going against VoIP continues to be that people want, quality, reliability and convenience and VoIP does not provide some of that. But the main reason for them is the expensive switching system that this carriers currently have.
Internet Phone systems make more sense for businesses, in economic perspective too as infrastructure requirements. Existing cellular companies have decided you're their existing infrastructure in order to keep their distance online telephony, yet it's about time when each of the circuit switched networks will be converted into packet switching networks.
The interest in VoIP gives an opportunity to providers and handset providers globally to modify their business models. Functionality available from IP telephones in addition to the charges has forced many providers to embrace VoIP service internet phone systems in addition to the present infrastructure.
Companies like AT&T have already started taking care of their infrastructure to compliment IP networks. Companies like Verizon who have started providing internet telephony have jacked up their data usage charges to pay the initial investment. The functionality aspect of VoIP is really a driving force for the carriers to embrace VoIP even when they still cancel internet telephone systems as not viable.
The cellphone manufacturers can also be geared up and so are providing Wi-fi compatible handsets in order to connect seamlessly to the hotspot available and switching together while moving. Blackberry has handsets which uses Wi-fi as opposed to GSM or CDMA to make telephone calls and exchange data. While the infrastructure is really a switch from cellular networks to Wi-fi networks, a choice of both the networks is sustained by mobiles as well as the networks are switched seamlessly while switching derived from one of area to a new.
The seamless switching from conventional mobile networks and connecting towards the Wi-Fi on the move leads to Fixed-mobile convergence (FMC). This cuts down on the operating costs and provides huge bandwidth to the user. The network service provider companies can thus improve productivity by minimizing costs.
A femtocell could be thought of as a technology for that extension of a service provider's network via broadband. This is also an alternative way to provide FMC. Femtocells are often provided by mobile network operators to home and small company users who would like extended coverage at their location. As the femtocell is connected on the location's existing broadband connection, it could provide value-added services in addition towards the previously available services- and excellent network coverage. The indoor network coverage using any femtocell is with the order of 10 meters.
The switch between wider cell along with the femtocell is seamless and communications are directed automatically via femtocells when the user is the range of it. The most common underlying technologies for femtocells are WCDMA, CDMA2000, and WiMAX.
There are certain issues related to femtocells, the foremost being interference caused to the overall network due to the femtocells. Some other concerns feel at ease location from the equipment, making emergency calls, and looking after Quality of Service.
