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.
• Long Term Performance: Once the device is installed, there is typically no
reason to move, or update the eFemto. This unit is also maintenance free and
requires no regular maintenance.

4.2 eFemto Network Diagram
The eFemto may be deployed as a single cell or multiple eFemtos may be deployed as a
cluster configuration. The device is IP-based and plugs in directly into an existing IP network
within the customer’s premises. The following diagram is a typical network diagram for a
standalone eFemto device within a customer’s premise.
Figure 2 - Single eFemto deployment network diagram
The following is a typical network diagram for multiple eFemto devices within a cluster
configuration in a customer’s site. In a cluster configuration, it should be ensured that all
the eFemtos within the cluster are reachable across the LAN. One way to do this is to
connect all the devices with the same IP subnet. If different IP subnets are used for a
cluster, then the routers must be updated accordingly for all subnets to be reachable.

•For optimal performance of the device, a back haul bandwidth of 5 Mbits should be
reserved for each device.
•For cluster configuration, each device within the cluster needs its own linear back
haul bandwidth. All the devices within a cluster require the same back haul network
for optimal performance.
Static IP Addressing Scheme
The eFemto supports static IP addressing for the device. The device is shipped from the
factory using DHCP IP addressing scheme. The USB cable provided should be used to set
static IP address for the device (see EdgePoint PRO - USB Console User Guide for more
information).
When using static IP address for the device, along with the IP address, the Subnet Mask,
default Gateway and DNS server information should also be provided to the device using the
USB connection.
4.3 Hardware Configuration
The eFemto offers a unique combination of 1xRTT and EV-DO radio and controller in one
physical platform that is differentiated from other systems. The eFemto comes equipped
with a Network Listener module which aids the device in sniffing its RF environment to

non-volatile memory location. The eFemto will automatically communicate with the
operator’s network to download a service image as well as perform various self
authentication and self configuration steps before turning its RF on to service the mobiles.
When the eFemto is powered on for the first time, it will follow the following steps:
•get an IP address assignment from LAN
•Initiate an IPSec tunnel establishment with the SeGW for communication with an
operator’s network
•Start the communication with the FSM to receive the service image from it
•Once a new service image has been downloaded from FSM, the eFemto will save this
image to its non-volatile memory area and will perform a self reboot
•After the reboot, the eFemto will setup the IPSec tunnel again with the SeGW, start
communication with the FSM and start acquiring a GPS lock
•It may take any time between 30 to 45 minutes for the eFemto to become
operational the first time that it is installed
