Digiweb require that the receiver they install must have a clear line of sight to their transmitter. This transmitter is located on top of the highest building they can find e.g. in Drogheda it is on top of the Lourdes hospital. Frustratingly, an obstruction like a tree or a shed can decide whether or not you receive their signal. In my estate, for example, the guy across the road can receive their signal, but I can not! Digiwebs` engineers must also fix the receiver to an exterior or interior wall, and relay a cable to the modem.
Clearwire is slightly different. They don`t operate on a line of sight principle, but quality of signal does vary in their coverage areas. The installation is much faster, as it does not require a receiver to be fixed. It only requires a modem pointed in the general direction of their transmitter. This modem can be taken with you wherever you go, as long as they have coverage in those areas.
Pricewise Digiweb is cheaper with a 2Mbps download package for €240 per annum. Clearwire have a 1Mbps package for €29.95 per month (€359.40). So that equates to half the speed for €119 extra per annum. They are also sneaky in that they charge €39 extra if you do not sign up for 2 years (minimum 1 year contact).
Finally if you like downloading music from peer to peer sites like MP3Rocket or Limewire, don`t get Clearwire. They have a fair usage policy based on their findings that the top 5% of individuals downloading files were drastically slowing down internet surfing for others. Digiweb have no such policy, so you should find that Clearwire has a more reliable service.
