- Outdoor macrocells may not have the capacity to deliver high speed internet, and thus may attract lawsuits from customers unhappy with the service.
- Femtocell nomadicity, as customer move them to other locations (e.g. holiday/second homes), which may disrupt outdoor networks.
- 911 emergency calls should be available from any femtocell for any user. But what if the femtocell has been moved (see above point)
- Billing issues, including customers believing they were on their femtocell when they weren't (and being charged by the minute instead)
- Voice quality and data speed expectations from customers. Early CDMA femtocells (Sprint Airave) did not include high speed data technology and so it's important that advertising claims match product capabilities.
- Roaming. Can femtocells be used to avoid roaming charges?
- Interception. Can femtocells be used to intercept calls which are handled as normal, but recorded/offloaded to the femtocell owner?
Whilst not all of the above issues will seriously affect operator's bringing the femtocell products to market, it will impact on how they are advertised. Policing of femtocell nomadicity and concerns about snooping into cellphone calls may be the more important issues to address.
