White Paper: Mobile Access Indoor Wireless Solution and Cisco WLANs
Solution Overview
Solution Overview
Mobile Access's solution uses Ethernet CAT-5e/6 cabling to provide in-building cellular signal
distribution. The MobileAccessVE solution can reuse the same CAT-5e/6 used by Cisco Aironet Access
Points concurrently.
distribution. The MobileAccessVE solution can reuse the same CAT-5e/6 used by Cisco Aironet Access
Points concurrently.
The solution can be configured to operate in any the frequency used by the cellular provider. The Wi-Fi
signal is transferred in different frequency bands from the cellular frequencies. They do not interfere
with each other when in the air or on wire.

The following picture shows a Cisco switch, an Aironet AP and the MobileAccessVE solution
co-existent on the same CAT-5e/6 cable run while simultaneously maintaining full Ethernet capabilities.

Cabling notes:
•
Ethernet LAN packet signals passed over Ethernet cable frequencies between 0 MHz and 125 MHz.
•
Cellular signals are converted for transmission over the Ethernet cable to frequencies at 160 MHz
and above.

•
This configuration allows Ethernet cabling to be passive to cellular and Wi-Fi.
•
The separation of the analog cellular signals by the Ethernet cable pairs from the Ethernet LAN
traffic signals provides the LAN traffic full bandwidth capabilities.

•
PoE is transparent between the two technologies. Even if the MobileAccessVE devices are powered
off; the Cisco AP will remain fully functional. Similarly if the ethernet solution is switched off; the
MobileAccessVE solution continues to operate.

The MA Controller pictured above shows that two cellular services(Example Cell and PCS) can be
brought into the controller. There are 12 UTP ports than can transport those two cellular services to
12 MA VAPs and those 12 UTP ports are paired to/from 12 Cisco switch ports.
