“By year-end 2011, 70% of all new worldwide voice and data client-to-LAN  connections will be wireless”
Gartner Research

Wireless networks used to be a matter of convenience – allowing network access in boardrooms, some classrooms, common areas for staff, customers, and guests. With advances in wireless technology over the past few years and particularly with the IEEE 802.11n standard ratified, wireless technology is now capable of even replacing the edge of LAN networks and becoming the primary means of accessing mission critical data, voice and video content and applications.

Where WiFi is used instead of a wired LAN significant savings can accrue. CAPEX per user:

An 802.11n “optimized” network can deliver up to twice the range and five times the bandwidth of a 54-Mbps 802.11g wireless network. For organizations downloading large files or pre recorded rich media training content 802.11n makes wireless a practical solution. Depending on the type of files being transferred and the degree of network optimization results can be dramatic:

Transferring a 30-minute video file over an 802.11g network took approximately
10 minutes. Over an 802.11b network it took approximately 42 minutes. Over an
802.11n network it now takes approximately 44 seconds!

Fixed Mobile Convergence

Fixed Mobile Convergence supports the objective of full mobility and accessibility anywhere, while presenting the opportunity to manage cellular costs and leverage the corporate IT infrastructure. Supported dual-mode smart phones enable calls to be placed over a cellular network and over premise based IP PBX systems where there is a properly provisioned WLAN network integration with an IP PBX.



Organizations are increasingly adopting LEAN management principles and reviewing their operations in search of increased efficiency, improved services to customers and opportunities to eliminate waste. The primary objective of Lean is to eliminate non-value adding activities to shorten production time and efficiently use limited resources.


IP Surveillance

A lower total cost of ownership: especially where new installations are being considered (not having to install a CCTV network cabling infrastructure in addition to the data network avoids an added CAPEX investment). Selecting IP over CCTV will present new opportunities for surveillance applications and advancements in system features and functionality.



Deployment of IP phone lines has surpassed analog lines worldwide and large enterprises with many distributed sites have increasingly adopted VOIP over POTS digital solutions. At COMU Networks we take a comprehensive view of VoIP within the context of current and future business needs and the overall network infrastructure.
