Bzeek Offload Solution Bzeek Offload Solution LegalityLegality

Many Internet Service Providers (ISP) contracts forbid sharing WiFi.

This is mainly to stop freeloaders from getting free Internet without paying

Bzeek does not allow and prevents freeloaders.User must have an existing broadband subscription to use

Bzeek with their iPhone.Therefore Bzeek has positive affect on ISPs encouraging

people to have Internet at home as they get faster Internet on the roam

Bzeek sharing is like a consuming a special content at home – a content that gives you fast WiFi when you roam. It’s like moving some of your unused bandwidth at home to be used where the user is roaming

Forbidding this content service would be interfering with net neutrality – it’s similar to Skype that uses idle bandwidth to relay calls of other users
