Why not just use the Airave alone? The Airave is not a booster or repeater, it's an actual mini cell site that puts out it's own signal.
Reason is I don't get good reception at home with my mobile broadband card and don't have access to DSL, Cable, etc. I really need the zboost to get enough signal to use my sprint broadband card. I don't even know if the airave will work with mobile broadband card. I read where it required a DSL, T1 or cable connection to function properly. Hopes this better clarifies where I'm coming from. Thanks.
