Voice over Wireless IP
Combining VoIP with 802.11 wireless LANs to create a wireless telephone system for offices is an emerging market segment. VoWIP enables businesses to leverage their wireless LANs to add voice communications, enabling companies to deploy and manage voice and data over a single wireless backbone.
From a network perspective, VoWIP applications require some reservation of bandwidth to support the real-time nature of voice. Proprietary standards like Spectralink Voice Priority (SVP) are today's solution; however, the IEEE is developing the 802.11e standard for quality of service as a long-term solution.
Voice over Wireless LANS When most people think of wireless LANs (WLANs), they generally only consider transferring data while using applications such as a Web browser, e-mail client, for file transfer, etc. It's possible, however, to use a WLAN as the transport system for carrying telephone traffic from mobile users as well.
A significant benefit of mixing telephone traffic with data on a WLAN is to provide mobility and make use of a common infrastructure. The support of a common system for both data and voice traffic is generally simpler and less expensive than two separate entities.
and Wireless Networking Voice over Internet Protocol, or commonly known as VOIP, is basically a type of software and hardware which allows people to use the Internet as the transmission medium for telephone calls by sending voice data in packets, or datagrams rather than by traditional circuit transmissions of the PSTN. It enables you to communicate with anyone who has a regular phone number.
VOIP has emerged as a viable way to drastically cut costs of telephone calls, since telephone calls over the Internet do not incur a surcharge on what the user is paying for internet access. One may wonder why there exists a demand for wireless VOIP. Again, money is the simple answer here. Businesses take great interest in decreased communication costs while making use of a reliable and good quality service. Wireless VOIP can be classified as VoWiFi, or Voice over Wireless Fidelity.
Over Wireless LAN with Ready WLANs (Wireless LANs) are still in the experimental phase at most companies. Why? Because wireless security standards remain in flux. But a more obvious obstacle to wholehearted adoption is the lack of a compelling need for wireless in the average office, which already has a perfectly functional, wired LAN in place.
Well, here's a thought: How about replacing or supplementing your current phone system with a VoWLAN (Voice over WLAN) system? Just take an ordinary wireless network and add a VoWLAN server along with laptops, PDAs, or newfangled Wi-Fi phones to run the client. Instead of workers wasting time playing phone tag, they can field calls wherever they roam on campus - or even on the road, if there's a Wi-Fi cloud nearby.
The pros and cons VoIP Over Wireless Voice over IP (VoIP) technology allows companies to cut the telco cord and make phone calls over the internet.
Now, with VoIP over wireless - also called VoW, VoWiFi, wVoIP, and a number of other acronyms
- organisations can cut all the cords. Numerous vendors are offering Wi-Fi IP phones that operate on the same 802.11 technologies used for wireless networks.
According to a study from Infonetics Research, sales of Wi-Fi IP phones will likely reach $3.7bn (£2bn) by 2009. The market already totalled more than $125m in 2005, and it's growing steadily, particularly in business fields that have many mobile workers. That includes people who work in hospitals and factories, on sales floors, etc.
Voice over wireless Today?s businesses are using wireless networking to give employees immediate access to the business applications and communication tools they need to do their jobs effectively. By adding voice-over-IP (VoIP) technology to their wireless networks, they can further improve collaboration and responsiveness and discover new ways to reduce costs.
By adding voice services on the Cisco Unified Wireless Network, businesses can enable their voice communications systems with the mobility and flexibility of wireless networking. Designed to complement a variety of voice clients, the network is optimized for voice services. The network builds upon a highly scalable, centrally managed architecture, designed to support pervasive deployments. Additionally,
there are some supports features such as included here:- * Quality of service
* Fast secure roaming * Diverse client support * Simplified management
The Voice over Wireless At-A-Glance Today, organizations must bemore agile and responsive than ever. They face new challenges of globalization,
a geographically dispersed workforce, and increasing reliance on real-time communications in every aspect
of their operations. And they need to give employees access to voice, messaging, and conferencing tools,
both inside and outside the workplace. Nearly every organization can benefit from wireless deployments that allow employees to move freely
around but still be connected to data and communications applications. By adding voice-over-IP (VoIP)
capability to their wireless networks, organizations can further improve collaboration and responsiveness,
and realize new cost savings. The Cisco voice-over-wireless LAN (VoWLAN) solution lets businesses
and other organizations bring the mobility and flexibility of wireless networking to their voice
