Despite the striking claims for Lucent Technologies' Common Operations, or COPS, the software will probably yield at best an incremental improvement in global wireless service.
The reason lies in one important limitation of COPS: It would not eliminate the need for users who want to roam between networks with different standards to have cell phones with different radios--for example, one for CDMA and another for GSM. COPS will not allow a CDMA-only cell phone to roam into a GSM network.
The major wireless carriers have already started to address the demand for global roaming by striking agreements with each other. For example, Nextel Communications uses the iDEN standard but has roaming agreements with GSM carriers in Europe. Customers of those carriers who travel abroad can get dual-radio handsets that work on both networks. Thus, Nextel can offer service to its customers who travel to Europe without having to pay a fee to a carrier there for carrying a call on its GSM network. VoiceStream, a GSM carrier, has similar arrangements with Europe's GSM carriers.

Lucent calling the COPS
To put the whole issue into perspective, international calling accounts for only a fairly small fraction of the global wireless market. However, global roaming is important to multinational corporations, so carriers find it a good selling point. COPS may make global roaming easier and cheaper to implement, but it's probably not going to change the market fundamentally.
