Continuing the use of mobile phones to its logical conclusion, mobile phone Operators and phone manufacturers are delivering solutions and pricing plans that allow the wireless phone to completely eliminate the wired phone. The End User can get the best of both worlds: lower cost and more functionality. I’ve run the numbers for individuals and enterprises, and it works. (I use it in my Home Office every day.) Benefits: One number, always reachable, one voice mailbox, etc. Users can choose to merge their wireline and wireless systems, but the end game is to completely eliminate the wireline (“cut the cord”).

Wireless + Wireline (Interim Step)

If the administration prefers to keep the desk phone (for regulatory or policy reasons, to track corporate communications), then the wireless device can work as a wireless extension of the desktop phone (see the example of BlackBerry Mobile Voice System). This is a lot more complicated to maintain: more gear added to allow the mobile phone to act as an extension of the office PBX, and more maintenance of that gear. This solution is only desirable for those that must keep the wireline phone.


Maximum savings of $1,000/year occur when the wireline or IP phone is eliminated. This solution is simple and easy to implement, as it does not add gear, it eliminates it. Eventually, the entire wireline solution will be eliminated, leaving the office with a wireless-only solution. This solution can be implemented using either (a) existing Wi-Fi or (b) a dedicated, in-building femtocell. Read on for a comparison of these two options and existing examples of these solutions, which concludes that UMA over Wi-Fi is best today, but Femtocells will eventually be the best solution.
