4 eFemto Device Installation
4.1
Overview
The eFemto is a compact cellular access point, supporting both cdma2000 1xRTT and
1xEVDO Rev0/Rev A subsystems. The combined functionalities of BTS, BSC, and PCF are
supported within the cdma2000 1xRTT sub system. Further, the eFemto contains the
capability for interworking standard IOS protocols to SIP messages on the back haul
network for cdma2000 1xRTT handsets. For the 1xEVDO sub system, the eFemto supports
the combined AN and PCF functionalities. The entire communication with the Operator's
network goes through a secure IPSec tunnel. This tunnel originates from the eFemto and
terminates at the SeGW. The eFemto expands 3G cellular services inside buildings so mobile
users can experience full voice and data service in areas that have inconsistent or no
cellular signal. Typical installations include office buildings, warehouses, high rises,
convention centers and other in-building hot spots.
eFemto Advantages:
Security: Secure and reliable connection into the operator's network. The
•
eFemto uses a secure VPN tunnel to access an operator's internal network. The
eFemto provides self as well as subscriber authentication to protect against fraud
and illegal usage of the device.
Scalability: Scalable to any number of Femto cells within an operator's network
•
with minimal impact to the existing infrastructure. Each eFemto is easily
configurable remotely from the operator's network using FSM.
Minimizing Interference: The eFemto comes equipped with internal hardware
•
and algorithms to minimize and mitigate RF interference towards existing
networks.
Seamless Services Support: The eFemto services are compatible with any
•
standard-issue CDMA cellular phone or AirCard. The eFemto supports E911
emergency calls. Further it supports feature transparency with the CDMA Macro
network.
Single Cell or Cluster Configuration Support with Mobility: The eFemto can
•
be deployed as a single RF cell or as a cluster of Femto cells. Peer-to-Peer soft
handoff is supported within the clusters. Support for user mobility with soft
handoff as well as hard handout from the Femto cell to the Macro.
