VoIP Over WiFi for Businesses: Sending Voice Over the Wireless LAN

VoIP Over WiFi For Businesses: Sending Voice Over The Wireless LAN

The convergence of data in addition to voice networks inside the business environment takes on a brand new twist with the emergence of wireless networking. The freedom of mobility offered to users in a wireless LAN has proven to provide a noticeable boost in productivity, efficiency, in addition to. Employee morale. No longer is usually the work force tied to their desk when on the job. Workers can access company files in addition to receive important communications via anywhere on the company campus which is usually in range of a wireless access point.

With voice communications thrown into the mix, mobile users can stay in touch while roaming the property inside or out, in addition to even on the road. The acceptance of the fixed to mobile convergence concept by the telecommunications industry only promises to fuel the fire for the adoption of VoIP over WiFi.

The Challenges of Implementing VoIP over WiFi Networks

As with any emerging technology, there are challenges to overcome. The development of the converged network, ie data in addition to voice on the same IP based LAN, while yet to be established norm, is usually proving to be beneficial for businesses via both a cost in addition to productivity perspective. Adding the prospect of VoIP over a wireless network brings up a whole brand new set of issues.

VoIP is usually a time sensitive technology. Calls must be set up in addition to authenticated, in addition to voice packets must arrive at their destination without interference in addition to on time. This specific requires a near continuous network stream, uninterrupted by less sensitive data transmissions. The implementation of Quality of Service techniques on wired LANs assure which these voice packets receive priority, in addition to call quality issues such as latency, jitter, in addition to packet loss have been adequately addressed.

Enter the standards based wireless network, a technology in an earlier stage of development, in addition to more challenges incidence. While today's wired network provides plenty of bandwidth for both voice in addition to data to coexist, WLANs provide less bandwidth, in addition to Quality of Service issues must be revisited. Security measures such as authentication in addition to encryption must be implemented in addition to can add to the problem by increasing the size of the voice packet. Additionally, users on the move will traverse wireless access points where handoffs must be quick in addition to smooth.

The IEEE 802 standards governing wireless technology are evolving rapidly in addition to promise to deal having a broad spectrum of WiFi issues. Increasing the bandwidth available, prioritizing voice packs for QoS , authentication in addition to encryption protocols for security, in addition to enhanced roaming techniques are all being addressed.

Also in development is usually the wireless technology commonly known as WiMax , providing for the implementation of high bandwidth wireless communications covering distances of up to 30 miles. The evolution of WiMax could prove of great recognition to developing countries, as well as Metropolitan LANs.

Security in a VoIP / WiFi Network

Companies wishing to implement wVoIP must take security issues into consideration via the start. As in any IP network, the dangers of hackers, denial of service, highjacking in addition to spam, all lurk inside the shadows.

Because a wireless network uses radio frequencies as its transmission media, the security typically provided by a firewall in a wired network is usually not sufficient, simply because of the physics. Whereas to break into a wired LAN requires hackers to either be physically inside the network or to hack in through the Internet, in a WLAN they can grab network transmissions via the air while parked across the street. The security issues which network managers must consider in a VoWLAN are the privacy of conversations, in addition to the protection of the network infrastructure.

For WiFi networks, security has had a shaky start with the implementation of WEP as its security mechanism. WEP provides for authentication in addition to encryption between the user in addition to the access point, in addition to was found to be easily hacked. The 802.11i standard, adopted as WPA2 (Wireless Protected Access), provides for more robust security by requiring two way authentication between the user in addition to the network, in addition to uses AES (Advanced Encryption Standard) as its encryption engine.

As network managers plan the rollout of a wireless VoIP network, the greatest security threat which face is usually improper implementation. Building security into the design of the initial deployment can, in addition to should affect the network topology, as well as material costs. Failure to do so could lead to further expenses in loss of services in addition to network redesigns inside the event of compromise.

WiFi, VoIP, in addition to the Cellular Networks

Manufacturers of cellular devices are incorporating WiFi radios into their handsets at an ever increasing rate. brand new versions of mobile operating systems are coming out complete having a built in VoIP stack, inviting carriers in addition to manufacturers to add VoIP functionality to their devices. Dual in addition to Quad band cell phones can choose between the strongest network available, cellular or WiFi, in addition to place a call accordingly.

As cell phones become more like mobile offices, the benefits of a mobile work force become noticeable. inside the case of the road warrior , the ability to communicate via email, text messaging, video or voice, allows them to stay on the road longer without losing touch. inside the age of instant information, mobile office applications allow files to be downloaded, edited, in addition to uploaded, increasing the productivity of the traveler to the point where just about anything which can be done inside the office can be done on the road.

A cell phone which can switch between cellular in addition to WiFi networks can significantly reduce telecommunications costs at the corporate office. With WiFi hotspots popping up at hotels, caf├ęs, in addition to corporate LANs across the globe, mobile workers can stay in touch with office in addition to family both on in addition to off the job. With the addition of a VoIP service provider, cheaper VoIP calls can be made via any WiFi network at the push of a button.

Imagine, if you will, a future where one phone, with one phone number, can seamlessly traverse cellular networks, WiFi networks, cable in addition to PSTN landlines. Where roaming in addition to switching between disparate networks occurs without interruption or loss of call quality. Fixed Mobile Convergence is usually the buzzword of the decade, in addition to the IP Multimedia Subsystem (IMS) architecture is usually the standard which promises to get us there.

The goal of IMS is usually to provide all the services in addition to applications which the Internet provides, both current, in addition to as of yet unimagined. IP based services such as VoIP, Push to talk cellular (POC), videoconferencing, text messaging, community services, presence information in addition to file sharing, are just some of the possibilities. Designed to work with any fixed, mobile or wireless packet switched network, backwards compatibility for the legacy circuit switched phone system is usually provided through the use of gateways.

Although still in its infancy, IMS is usually already being implemented by AT & T as the platform inside the idea's newly acquired Cingular cellular network. Interest in investing in a brand new infrastructure by mobile in addition to fixed operators has been up in addition to down, as they weigh the costs in addition to benefits of the brand new technology.

As the technology of VoIP over WiFi networks continues to develop, businesses of all sizes can reap the benefits of increased mobility, productivity, in addition to significant cost savings. Standards committees are constantly working on ways to enhance security in addition to quality of service, in addition to as fixed mobile convergence gains acceptance inside the telecommunications industry, more choices inside the services offered in addition to the IP applications available to businesses are sure to follow. What will also be interesting to watch, is usually how these very bandwidth intensive applications will be priced by the carrier networks, in addition to how the idea will affect the neutrality of the Internet.
