EdgePoint / EdgePoint PRO Product Description 2.2 EdgePoint Network Configuration The AirWalk EdgePoint PRO family of femto cells is CDMA devices that are capable of simultaneously supporting 1XRTT and 1XEVDO networks along with a 10 frequency hopping pilot beacon on the same device. The EdgePoint and EdgePoint Pro femto cells are configured and maintained using standard based TR069 with a proprietary device model. Each device is also equipped with a network listener (NL) that is used to sense the current radio environment for purposes of auto-configuration. The EdgePoint femto can be configured to provide additional functionality such as RF mitigation, an onboard Ethernet switch and an analogue telephone adapter for supporting independent wireline phone support. The 1XRTT call support uses SIP and RTP for signaling and bearer respectively, optionally the 1XRTT call can also be supported using standards based 3GPP2 IOS 5.x for signaling. The EdgePoint residential device comes in an attractive desk top packaging that adds luster to any home furnishing. The EdgePoint Pro is an enterprise unit that comes in a standard rack mount form factor or an attractive yet non-obtrusive wall mount unit. The EdgePoint Femto cell is a key element in the AirWalk CDMA End-To-End Network Solution. The EdgePoint Femto cell provides a radio communication link to the mobile subscriber devices using the CDMA air interface protocol. The EdgePoint Femto cell fills in gaps in coverage and also can provide primary coverage in areas that suffer from poor or non-existent CDMA coverage. The combo EdgePoint Femto cell gives the service provider an option of using a next generation IMS core or a MSCe at the core to provide voice and data service. The EVDO capability of the femto cell, provides service using the existing PDSN and AN-AAA devices. A Femto BSM (U-BSM) automatically provisions an EdgePoint Femto cell for service by using data on the radio environment, provided by the Femto Cell network listen function, along with service provider policies. The U-BSM also provides configuration management, performance management and fault management either on demand or autonomously. The following figure shows the AirWalk EdgePoint Femto Cells and its relationship to the CDMA Core Network elements. Together with an IMS, a Convergence server, PDSN and AN-AAA components, the AirWalk EdgePoint Femto cell provides an end to end personal or business CDMA wireless solution. As shown below, the EdgePoint Femtocell devices utilizes common interfaces to the core network equipment, consisting of IPSEC and SIP to the IMS core or IOS-4.2+/5.0 to a MSCe, and RTP to the Media Gateway, A10/A11 to the PDSN and TR069 to the U-BSM..

EdgePoint / EdgePoint PRO Product Description Figure 2 - AirWalk Network diagram The AirWalk EdgePoint Pro utilizes the customer premise existing IP connection to the IP core and Internet. The base interface of the device is IP over Ethernet and is capable of using IP provided by DSL, Cable, Fiber or bonded T1 besides other not as common technologies. In addition to using standard IP the EdgePoint provides secure communication over IP by the use of IPSEC to interconnect to security gateways and Femto gateways. As mentioned on section 2.2, AirWalk EdgePoint/EdgePoint PRO 1xRTT contains two different paths to set up a voice paths. Figure 3 shows the SIP-IMS implementation consists of several key components within the network. It requires IMS core that will support CDMA interface. Also for this network diagram, it is assumed that Security Gateway, SG, is provided by the operator to allow the service to be manageable in IP-Security across the network.

EdgePoint / EdgePoint PRO Product Description 3 EdgePoint PRO Hardware The EdgePoint PRO architecture combines the traditional concepts of the BSC, BTS, AN, ANC, and PCF into a homogeneous architecture. The EdgePoint PRO provides signaling, voice and data is connected to the core using the existing connection to the internet (Cable, DSL, fiber, bonded T1). In order to provide these services, the EdgePoint PRO needs several major components. In section 3, major hardware components are introduced and described. 3.1 EdgePoint PRO Digital Hardware Overview The EdgePoint PRO architecture is based on a Freescale MPC CPU operating on VxWorks RTOS, Real Time Operating System. The device is capable of supporting 1XRTT and 1XEVDO simultaneously. The EdgePoint PRO support 28 voice calls in its 1XRTT configuration, and 32 data calls in 1XEVDO simultaneously. The EdgePoint PRO is comprised of digital and radio portion. The Figure 8 depicts all the components that are part of the digital portion of the board. 1xRTT ( BTS & BSC) IPSec EVDO ‐ RNC EVDO ‐ RN PowerPC PowerPC QSC6085 6825 GPS 5025 Transceiver Ethernet Serial USB DO 1x 1x 1x T/R PB/2ndRx T/R NL Rx Figure 8 - EdgePoint Pro Digital Board The major hardware components on the digital board include Freescale PPCs as its main processing units. It also holds a Qualcomm CSM 5025 for 1XRTT and a Qualcomm CSM 6825 for 1XEVDO for the CDMA baseband signals. For the three Lime XCVRs, LM0006 is used for the RF signal modulation.

EdgePoint / EdgePoint PRO Product Description Ethernet, serial, and USB ports to provide debug and communication interface to external devices. 3.2 Power PC The EdgePoint PRO comprises of two PPCs processors (MPC8347) and controls other components within the EdgePoint-Pro device like Qualcomm chipsets, GPS module, Network Listener, and transceiver (XCVR). The PPC provide critical role within EdgePoint PRO and below are some of the highlights of PPC’s function: 1. The PPC handles the IPSec communication that interface with security gateway, SG. 2. The first PPC handles 1xEVDO RN portion of the packet flow by interfacing with CSM6850 chipset. PPC packetize the received air message and packetize them. The packetized data is sent to PDSN. 3. The second PPC handles 1xRTT portion of the call processing as well as the RNC side of the signaling messages. This is accomplished by interfacing with CSM5000 chipset. Below figure 9 shows the PPC’s functionality and some of the controlling block.

EdgePoint / EdgePoint PRO Product Description 3.3 Qualcomm chipsets The EdgePoint Femto consists of two Qualcomm chipset. The CSM6825 handles the baseband signaling for the 1xEVDO portion. The CSM5025 handles the baseband signaling for the 1xRTT portion of the CDMA signal. In addition to providing 1xRTT baseband signal, 5025 also sends Pilot Beacon transmission to 1x mobiles. These chipset can support up to 28 simultaneous 1xRTT voice call, and 32 simultaneous 1xEVDO active data calls. In addition to providing the call signal, Qualcomm chipsets also provide Pilot Beacon, PB, functionality that allows surround mobiles to redirect their RF signal to the EdgePoint PRO. 3.4 GPS Module The GPS module is a essential part of the CDMA system due to the time sensitive nature of the technology. The GPS module provides synchronization of the local time and also location information. Below figure 10 shows the block diagram of GPS module to EdgePoint PRO components timing scheme.

EdgePoint / EdgePoint PRO Product Description Figure 11 - Network Listener 3.5 Network Listen Function The NL (Network Listener) function controls the mobile receiver in the EdgePoint PRO to obtain information on the current CDMA environment that the EdgePoint PRO is operating in. It sends this data to the U-BSM which uses predefined rules to determine the configuration of the radio environment. Figure 11 depicts interfaces and the components that are required for the NL to be operational. The NL is control through USB interface and need special firmware to be operational. 3.6 EFTR (Enterprise Femto TransceiveR) Board The EFTR is a module that gets signal from CSM chipsets and converts the signal to the RF components. The EFTR for EdgePoint PRO has 3 transmit paths: 1. CDMA1x 2. CDMA DO 3. Pilot Beacon In addition, the FTRB provide 3 received path and 1 received path for the mobile receiver used for the NL. The 3 received paths have following roles: 1. CDMA 1x 2. CDMA DO 3. Noise Measurement Path-Second Receiver The EFTR provide maximum output power of 0 dBm on each path. The received sensitivity is - 115dBm. The signal from the EFTR is inputted to the built in amplifier, FEU. The EFTR uses Lime chip model LMS6002D. The EFTR is a module that will be selected based on different band classes. Proprietary and Confidential Page 16 of 17
