The deployment of 700 MHz Long Term Evolution (LTE) will increase the importance of which of the following?

The deployment of 700 MHz Long Term Evolution (LTE) significantly emphasizes the importance of controlling and reducing leakage and ingress issues due to several technical considerations associated with this frequency range.

700 MHz LTE operates on a lower frequency band, which allows signals to travel longer distances and penetrate obstacles better (such as buildings). However, this also makes the system more susceptible to issues related to leakage and ingress. Leakage refers to signals escaping the intended area, while ingress pertains to external signals contaminating the system. These two issues can lead to degraded performance and reduced quality of service, particularly in densely populated areas where multiple signals may overlap.

To ensure that LTE systems operate efficiently and offer the expected levels of service, it is vital to maintain the integrity of the transmission environment. This involves rigorous measures to minimize leakage from the network and ingress from outside interference. Addressing these issues directly contributes to optimizing network performance, enhancing coverage, and maintaining service quality for users.

Other aspects, such as upload speed, customer service strategies, and data cap limits, are essential components in the overall service offering but do not have the same direct and immediate implications on the technical performance of the network as managing leakage and ingress issues does when deploying a new frequency band like 700 MHz LTE.
