The dual mode handset market ï¿½ handsets capable of seamlessly switching between cellular and WiFi (News - Alert) networks ï¿½ promise unparalleled mobility options for users. With these devices, customers will not only be able to save time by remaining connected, but they also will be able to save money by connecting through WiFi networks, which are being deploying in cities worldwide. Indeed, some reports indicate the market for these devices will eclipse 100 million by the end of this decade, making it a seemingly lucrative opportunity for handset producers.
Naturally, there are challenges involved, as is always the case with cutting edge technology. Battery life has been one hurdle, though most manufacturers now promise upwards of 100 hours of standby time. Cost, of course, is also a major obstacle. These devices will not be inexpensive, at least not for some time, so it may well be that businesses willing to outlay the cash to better enable their workers to communicate on the road will drive the market for these handsets, at least initially. Perhaps most importantly, to maximize the functionality of these devices, the proper switching infrastructures must be in place to take advantage of the seamless transitioning capability.
For business users and consumers alike ï¿½ and they ultimately become one and the same ï¿½ the following is a selection of devices that feature dual mode technology. For more information about the devices, please contact the manufacturers or carriers.
BroadVoiceï¿½s dual mode wireless VoIP/GSM phone, which it calls ï¿½Falcon,ï¿½ allows users to take advantage of BroadVoiceï¿½s unlimited VoIP calling plans using WiFi networks, but allows users to also make calls on cellular networks when outside WiFi coverage.
Once a BroadVoice customer buys the Falcon and activates a phone number, he can begin making and receiving SIP-based VoIP calls over WiFi immediately. As soon as the customer plugs in a standard SIM card GSM-based cellular carrier, he will be able to make cellular calls as well. Calls to either the BroadVoice number or the userï¿½s cellular number can be received on the Falcon.
With BroadVoiceï¿½s E911 capabilities, the integrated Falcon also becomes completely E911 compliant.
BroadVoice announced the Falcon in April, and said the device would be available sometime this summer.
