Shared infrastructure for LTE services

'Distributed antenna system solutions allow an operator to add capacity in the network exactly where it is needed…'

When planning LTE upgrades, one major factor is cost. It is clear that 3G macro-style networks will not be sufficient for LTE services, and that smaller cells will be required. But mobile operators are rightly concerned about the cost of deploying the broadly distributed infrastructure that LTE services will require. The challenge with LTE is that it requires far stronger signal coverage and far more capacity per user than legacy mobile services. These needs cannot be met with macro tower base stations (BTS) alone. There are several issues to be resolved: • Insufficient coverage. LTE networks commonly operate at frequencies above 2 GHz, which attenuate much more quickly than the lower frequencies used in 2G networks. In traditional macro networks, there are 'shadow' areas where signals cannot reach…
