Considerations to make when implementing VoIP over Wi-Fi

Many businesses are already well aware of the advantages that come with the implementation of a voice over inter protocol (VoIP) system, with the number of applications running over wireless infrastructures beginning to increase.

However, when it come to implementing VoIP on a Wi-Fi network, there can be various challenges, which, if not properly addressed, can cause problems to a company's operations.

The first consideration is the fact that voice transmission is more sensitive than that of data. It means that while your Wi-Fi system may be more than capable of handling most basic demands in terms of internet use, it might not necessarily be suited to voice transmissions.

As VoIP is particularly sensitive to issues such as packet loss, there can be no room for weak signals, range limitations and interference from other devices on the same frequency.

Your wireless network needs to be reliable, as users will expect their phone systems to be more reliable than their computers, always expecting a dial time each time, as well as high sound quality.

It is therefore best to ensure that in order to avoid any disruption or delay with VoIP applications, to keep data transmissions on separate networks.

VoIP packets can be given priority by way of organisations rolling out quality of service (QoS) features.

Security is also a greater consideration for wireless VoIP systems, with the process of sending phone calls over a public IP network presenting a greater risk than those offered by telcos.

The process of transmissions going over airwaves as opposed to cables makes them easier to intercept, while common VoIP protocols such as SIP have their own security vulnerabilities.

It means that organisations need to be vigilant in ensuring that Wi-Fi networks carrying voice traffic are properly secured through authentication and encryption.

Such problems may seem to justify not introducing a wireless VoIP network. However, the added flexibility and reduction in operational costs should be more than adequate in terms of motivation to get things right.
