Delivering on the promises of 4G LTE

With commercial LTE deployments well underway around the world, many network operators are finding themselves running three generations of technology at the same time. Not only is this situation resulting in many operational headaches due to the management of separate 2G, 3G and 4G LTE networks but also because the traffic running across those networks is becoming increasingly unbalanced.

Inter cell interference issues greater than expected

Technical considerations dominated much of the discussion at LTE World Summit this week, with Chinese equipment vendor ZTE claiming that inter cell interference is much higher than first thought and proposed solutions built into the LTE specification might not be sufficient remedy.

With the growing number of access technologies and air interfaces, mobile operators are faced with the daunting task of carefully deploying current networks but also maintaining compatibility with future standards that have not yet entered the market. In developed markets in particular, mobile operators may be faced with radio infrastructure lifecycles of a few years, making it extremely hard to secure Return on Investment (ROI) for newly deployed equipment since marketing and user adoption always lags technology upgrades.
