As a network interface, only a wireless air interface that connects phones, antennas, and cell towers is presently commercially available. Backhauling mobile signals does not need the installation of any extra infrastructure.

Mobile networks are solely wireless when it comes to the air interface between phones and antennas and towers. What else is needed to backhaul cell signals?

In terms of air interface between cell phones, antennas, and cell towers, mobile networks are the only ones that are wireless. Mobile signal backhauling does not need more than that.

Because phones, antennae, and cell towers can only access mobile networks, these are the only ones accessible. Backhauling mobile signals requires no extra gear.

Mobile networks are totally wireless when it comes to the air interface between phones, antennas, and towers. What else is necessary for backhauling cell signals?

Mobile networks are the only ones that use a wireless air interface between phones, antennas, and cell towers. Mobile signal backhauling does not need much more than that.

Mobile networks are the only ones that are wireless when it comes to the air interface between phones, antennas, and cell towers. More than that isn't required for mobile signal backhauling.

In terms of air interface between phones, antennas, and cell towers, there are no wireless networks accessible, therefore only mobile networks are available. There is no extra equipment required for backhauling mobile signals.

Only a wireless air interface that links phones, antennas, and cell towers is now commercially available as a network interface. Signal backhauling for mobile phones does not need any additional infrastructure.

Due to the fact that there are no wireless networks accessible when it comes to the air interface between phones, antenna, and cell towers, mobile networks are the only ones that are now available. Backhauling mobile signals does not need the usage of any new hardware or infrastructure.
