The Marketplace for Wireless Voice-over-IP VoIP (Voice-over-Wireless-LAN VoWLAN)
The increasing growth of wireless voice-over-IP (VoIP) telephony results in more and more 802.11 Wi-Fi wireless networks being called on to support wireless voice phone calls. Mobile handsets, and notably products like the iPhone, have moved the enterprise into a wireless VoIP world.
Whereas once voice and data were managed as separate technologies, the convergence of telephony and datacom is a reality in the wireless enterprise today. Connect802 has been providing wireless VoIP design and consulting services for many years and we've watched the industry mature in the triple-play (voice-video-data) marketplace. We've also seen the dramatic problems that occur when an 802.11 Wi-Fi wireless LAN that is designed to support Web browsing, file transfer and email is used to support wireless Voice-over-IP without proper pre-deployment assessment.
Voice-over-Wireless-LAN (VoWLAN) requires a higher level of signal power than does data transfer and Web browsing. VoIP requires that the received signal be more greatly separated from environmental noise (Signal-to-Noise Ratio SNR) and from nearby interfering 802.11 transmitters (Carrier-to-Interference Ratio CIR). Connect802 can create an 802.11 Wi-Fi wireless network design that will properly support wireless VoIP / Voice-over-Wireless-LAN (VoWLAN).
Are You Planning For Wireless VoiP?
Talk to the RF engineering team at Connect802 before you start your implementation of a Voice-over-WLAN (wireless VoIP) phone system - We've Got You Covered. Connect802 designs wireless VoIP systems to support Cisco, Avaya, SpectraLink, and the latest generation of multi-mode Wi-Fi/Cellular handsets. A proper design is the only way to assure the highest quality voice communications in an enterprise-class VoIP system. Call us to discuss how we can help.
Unlike some casual web surfing or checking email, your network infrastructure is going to have to provide a high level of reliability and performance to give you crisp, clear, and NOT DROPPED wireless IP phone calls. We can help you with your VoWLAN (Voice over Wireless LAN) design and Wi-Fi network to support your wireless PBX system from any vendor. Plus, in today's converging wireless LAN environment, Triple Play (voice video data together) is another key reason to make sure the Wi-Fi VoIP system is ready to support more than just VoIP.
Wireless VoIP can be a complete telephone solution for:
- Retail Stores
- Hospitals (...really; and Connect802 does Wireless Medical Telemetry Systems (WMTS) too, so we know RF and hospitals!)
- Car dealerships
- Mobile calls using VoWLAN technology
What Makes a Wi-Fi Different with Wireless VoIP?
802.11 radio chipsets used in wireless data devices (notebook computers and PDAs), handheld inventory scanners, and wireless VoIP handsets are essentially the same. They can all create connections with very low signal strengths and relatively low signal-to-noise ratios (i.e. noisy environments can support connectivity). The problem comes when data connections (for file transfer, email, web browsing, and similar activities) are compared to the requirements for wireless VoIP.
A wireless VoIP
call requires significantly higher
signal strength, and an even more
significantly high signal-to-noise
ratios. A typical "walk around" on-site
survey for a Wi-Fi network does not
assess 100% of a building's floor
space because an engineer can't walk
around to every corner and every
part of every room.
Unlike wireless notebook computers, which are typically used in a fixed or nomadic location (on a desktop, for example), wireless VoIP handsets are typically used while a person is walking. This demands an assessment of consistent, contiguous coverage that is not possible with a design that's based solely on a walk-through of a site.
Connect802 utilizes RF CAD modeling and simulation to augment the design process, and in many cases to completely eliminate the need for an on-site engagement. You get the right design the first time, without worrying about going back to correct dead spots or weak areas in your coverage.
