A “hotspot” only has a length of about 90 Meters so before VoWI FI can become a bonifide cellular competitor, it will have to address these issues first.

However, Wi Fi is gaining popularity, and VoIP phones are holding their own weight against cellular phones due to the fact that VoIP phones still use less bandwidth are considerably less expensive over all. Some cellular companies recognize that VoWi Fi phones will be the next big thing and are already designing dual, VoWiFi/Cellular phones. These phones are designed to access a hotspot, and then switch to a Cellular network when the caller has left the hotspot vicinity. For example, a caller could be in their office, and be on their hybrid phone using WiFi, if they step outside and leave the range of an access point, they will switch to cellular networks, when they reenter the building and are back in the wireless access point area, they will switch back to WiFi- all without losing connectivity during the call. You may be wondering why someone would want a hybrid phone; well it is simple- the WiFi calls are much cheaper (if not free) then the cellular.

We can expect to see more changes in the future as VoWiFi as it continues to gather a reputation. There are already many companies embracing VoWiFi, and other companies are addressing the needs for more stringent wireless security. For example, there are higher security networks in place now, that will decrease the chance of others tapping into your access points. For many wireless users, this has been the preferred method of wireless access.
