NETWORKING BASICS 001-9193-001 Version 1 Page 12 of 48 Sentry 4G 900TM User Manual 3. Networking basics 3.1 General Networking Definitions The Sentry 4G router is based on Ethernet connectivity and follows general IP networking guidelines and terminology. Below are definitions of some basic network terminology as they pertain to the Sentry 4G environment. Term Definition BTS Base Transceiver Station, fixed equipment that incorporates all radio-intelligence functions controlling the 802.16-2005 link with one or more Sentry 4G routers. CINR Carrier to Interference-plus-Noise Ratio, expressed in decibels (dBs), is a measurement of signal effectiveness. It provides information on how strong the desired signal is compared to the unwanted energy (interference plus noise). DNS Domain Name System: operates like a phone book to translate domain names (i.e., google.com) to IP addresses (70.212.19.1). The Sentry 4G unit functions as the DNS Server in the network. DHCP Dynamic Host Configuration Protocol: the DHCP server assigns IP addresses, gateway and subnet masks to all clients on the network. The Sentry 4G unit functions as a DHCP Server. Dynamic/Static IP A device with Dynamic IP selected may have a different IP address every time it connects to the network. A device with a Static IP will always connect with the same IP address. EAP-TTLS (Extensible Authentication Protocol-Tunneled Transport Layer Security) Is a universal authentication framework frequently used in wireless networks and Point-to-Point connections. EAP-TTLS is an EAP method that encapsulates a TLS session, consisting of a handshake phase and a data phase. During the handshake phase, the server is authenticated to the client using standard TLS procedures, and keying material is generated in order to create a cryptographically secure tunnel for information exchange in the subsequent data phase. During the data phase, the client is authenticated to the server using an arbitrary authentication mechanism encapsulated within the secure tunnel. Gateway A (node) device enabling data transfer between different networks (i.e., from a private LAN to a public WAN). LAN Local Area Network. A private network. MIMO Multiple Input Multiple Output. MIMO algorithms send information out over two or more antennas; the information is received via multiple antennas as well. This use of multiple antennas at both the transmitter and receiver provides a significant capacity gain over conventional single antenna systems and/or a more reliable communication. NAT Network Address Translation: A technology that allows hosts on the LAN with private IP addresses to communicate with public IP addresses on the WAN. This is an essential function of a network router. OFDM Orthogonal Frequency Division Multiplexing. 802.16-2005 being a wide area network is very sensitive to interference and multi-path fading. OFDM addresses these problems by partitioning the data stream into multiple narrowband transmissions in the frequency domain using subcarriers that are orthogonal to one another (do not interfere). These subcarriers are then reassembled for over-the-air retransmission. OFDMA Orthogonal Frequency Division Multiple Access. Allows OFDM to serve many terminals. Each terminal will be assigned a subset of the subcarrier set for a given time interval. Port A special number present in the header of a data packet in the data transfer
NETWORKING BASICS 001-9193-001 Version 1 Page 13 of 48 Sentry 4G 900TM User Manual process. Ports are typically used to map data to a particular process running on a computer. PPP Point-to-point Protocol: creating a direct link between two nodes in network communication. Private IP address Private IP addresses are addresses that will not be routed on external networks. Any device on an internal LAN should be assigned a private IP address to avoid contention. The suggested private address ranges are Class A: 10.x.x.x Class B: 172.16.x.x through 172.31.x.x Class C: 192.168.x.x By default the Sentry 4G unit uses the 192.168.1.x address range. RIP Routing Information Protocol, protocol that helps routers dynamically adapt to changes of network connections by communicating information about which networks each router can reach and how far away those networks are. SOFDMA Scalable OFDMA. With bandwidth scalability, Mobile 802.16-2005 technology can comply with various frequency regulations worldwide. SSID Service Set Identifier. This is a name used to identify a WiFi wireless network. Subnet A range of addresses assigned to a LAN. All devices connected in a Sentry 4G network must be on the same subnet as the Sentry 4G routers. Subnet Mask Binary string that separates the subnet portion of an IP address and the host portion. TKIP/AES “Temporal Key Integrity Protocol” is an encryption method used by the WiFi interface when operating in WPA mode. TKIP was designed to solve security issues in WEP (it is considered stronger then WEP). "Advanced Encryption Standard" is the encryption protocol used by the WiFi interface when it operates in WPA2 mode. WAN Wide Area Network, a public network. The Internet is an example of a WAN. WEP Wired Equivalent Privacy. This is an IEEE security protocol for wireless 802.11 networks. It is an encryption method used by the WiFi interface. WiFi (802.11b, 802.11g) Wireless Fidelity is an IEEE 802.11 standard for wireless LANs 802.11b is a standard for operating at 2.4 GHz frequency with data rates up to 11 Mbps 802.11g is a standard for operating at 2.4 GHz frequency with data rates up to 54 Mbps WiFi Access Point (802.11) A Sentry 4G unit can operate in 802.11 access point mode. It can communicate with other devices operating in 802.11 access point mode. WiFi Client (802.11 Infrastructure mode) A Sentry 4G unit can operate in 802.11 Infrastructure mode. In this mode it is a WiFi client and will try to connect to a WiFi access point. WLAN Wireless Local Area Network, a private network. Refers to the network covered by the WiFi interface. WPA/WPA2 WiFi Protected Access" is a subset of 802.11i (security mechanisms for wireless networks). "WiFi Protected Access 2" is the complete version of 802.11i.

The ETH0 and ETH1 Settings pages contain the basic configuration information required to customize your LAN with the Sentry 4G router as the network connection point. User configuration will primarily occur on this page. 5.4.1 IP Settings 5.4.1.1 IP Configuration Ethernet IP address: LAN IP of the SENTRY 4G unit. This address is entered into a browser on a local PC when logging into the Sentry 4G home page. To decrease the chances of unwanted access, this value should be changed from its default prior to use. IMPORTANT NOTE: Changing this value will cause you to lose connection to the Sentry 4G unit. Enter the new address in the browser to reconnect. If you forget an address or make a mistake entering the new value, it may be difficult to reconnect to the device. Ethernet Subnet Mask: The Subnet mask is used in conjunction with the Ethernet IP address to partition the address into the network (subnet) portion and the host portion. This value will be entered automatically by the software based on the class of IP address entered. It is not be necessary to change the default value once the Ethernet IP is entered. 5.4.1.2 DNS Masquerade See the definition for DNS in Network Basics in section 3.1 above.
CONFIGURATION 001-9193-001 Version 1 Page 25 of 48 Sentry 4G 900TM User Manual DNS Auto: The command enables/disables the Sentry 4G DNS server. Except in special cases, this should always be enabled. 5.4.1.3 DHCP Server Configuration DHCP Server: (Dynamic Host Configuration Protocol) A protocol used by client devices that are connected to the LAN port of this device to automatically obtain an IP address assigned by this server/router. Selecting Enable will configure this device to assign IP addresses to client devices taken from a pool specified by the values entered in DHCP start range and DHCP end range. If DHCP is disabled, the information must be entered manually on all PCs. DHCP Start IP Address/End IP Address: Sets the range of IP addresses assigned to the PCs. The user can limit the number of devices allowed on the network by limiting the range of IP addresses. IMPORTANT NOTE: The addresses in this range must be on the same subnet as the Ethernet IP IMPORTANT NOTE: The Ethernet IP should not be in the DHCP range. DHCP Lease Time: Number that dictates the length of time a device on the LAN can hold an IP address. In most cases, this should be set to the maximum (default value) of 86400. If this value is set too low, it can cause network connectivity problems. Domain Name Suffix: The DNS suffix to be assigned by the DHCP server. Preferred DNS Server: IP address of the preferred DNS server. Alternate DNS Server: IP address of the alternate DNS server. 5.4.1.4 Disabling DHCP server When DHCP server is enabled, any PC with physical access to the Sentry 4G Ethernet port will be assigned an IP address and have access to browse the Internet. This may cause security problems. Disabling DHCP server will allow the user to control which PCs have the ability to connect through the Sentry 4G unit. If changes are made to the network settings, be sure to keep a record of the changes for future use.  Disabling DHCP server is performed on the LAN settings page. Under the DHCP section, select Disable, then click Save. IMPORTANT NOTE: This also disables DNS Masquerading. Disabling DHCP server will remove all values in the DHCP and DNS sections. Record all values in these fields prior to disabling in case you are required to go back to the original configuration.  To improve security, change the Ethernet IP of the Sentry 4G unit from the default setting. IMPORTANT NOTE: If the DHCP server is disabled, and you do not have a record of the Ethernet IP, you will not be able to login to the Sentry 4G home page. On the network setting page of each PC set the following – IP address: Set a unique address on the same subnet as the Sentry 4G router – Subnet Mask: Set to the same value as the Sentry4G’s Ethernet Subnet Mask field – Default Gateway: Ethernet IP of the Sentry 4G router – Preferred DNS: Ethernet IP of Sentry 4G router
CONFIGURATION 001-9193-001 Version 1 Page 26 of 48 Sentry 4G 900TM User Manual When these settings are complete, the PC will have network access. 5.4.1.5 Static IP Setup If your network requires each PC to have a statically set LAN IP addresses, follow the previous procedure for all PCs on the network. If the network requires a mix of static and dynamically assigned IP addresses, assign static IPs outside the DHCP address range for PCs that require static IP addresses and allow the Sentry 4G router DHCP to assign the remaining PC IP addresses. 5.4.2 Statistics This tab displays information regarding the number of packets and bytes transmitted and received over the ETH0 or ETH1 interface. 5.5 WiFi (WLAN) A Sentry 4G unit can operate in an access point mode and in a client mode. In access point mode, the Sentry 4G router offers wireless tether. It forwards local WiFi traffic to application servers over the broadband 802.16-2005 network and works in parallel with Ethernet connection, providing for simultaneous WiFi and Ethernet connections (see Figure 13A). In client mode the Sentry 4G unit can automatically switch between broadband 802.16-2005 and WiFi connections providing for seamless handover when coupled with modern applications (see Figure 13B).

In some cases however, the Sentry 4G unit may need to communicate with a previously existing subnet other than its own. This route cannot be automatically generated; it must be manually entered as a static route by the user. The static route gives the Sentry 4G router its “next hop” instructions. Route no: A generic number assigned to the route. Multiple static routes can be assigned as long as they have distinct route numbers. Description: Nickname assigned to the route by the user. IP Address: This is the destination IP address that is delivered to the Sentry 4G unit. Since this IP address will not be on the same subnet, the Sentry 4G unit will not have a defined route, and will not know where to send it by default. Setting up the static route will inform the Sentry 4G unit where to send the data. Subnet Mask: The Subnet mask is determined by the subnet of the destination address Gateway: This is the address that the data packet will be routed to. Note: The device at this address must be a router that is either on the same subnet as the Destination IP or one with its own statically setup route to the destination address. If this is not the case, the packet data will be dropped.
CONFIGURATION 001-9193-001 Version 1 Page 34 of 48 Sentry 4G 900TM User Manual Metric: This sets the priority of the routes compared to other static routed defined. The lower the number, the higher priority the route. Click on “Add” when all necessary information has been entered. The route will be shown on the bottom of the screen (under Static Routing Table). Additional routes can be added provided they have a unique Route no, name and metric. Routes can be deleted by clicking the Delete Entry option of the desired entry. Note: Routing table (found under “Routing Table” tab) shows all routes, while Static Table (found under “Static Routing” tab) shows manually entered routes only. 5.6.2 IP Filtering IP Filtering provides certain Internet firewall protection. The user can enter up to 20 IP filters. Each IP filter is identified by a unique number (from 1 to 20). When IP filtering is enabled, any custom IP filter entered by the user as well as predefined IP filters will be taken into account when processing IP packets. See Figure 20. An IP packet passes through the filtering logic when IP filtering is enabled: 1) An IP packet is received on one of the interface and is destined to the Sentry 4G unit OR 2) An IP packet is sent by the Sentry 4G unit OR 3) An IP packet is forwarded by the Sentry 4G unit. 5.6.2.1 Predefined IP Filters Drop Remote Pings: If IP filtering is enabled, any ICMP echo request coming from the WAN interface will not be replied to. This prevents remote hosts from detecting your IP address on the WAN. Drop Remote IP Fragments: If IP filtering is enabled, any fragmented IP packets coming from the WAN interface will be dropped. Drop Invalid Packets: If IP filtering is enabled, any invalid packet received by the unit will be silently dropped. An invalid IP packet is one that cannot be identified. 5.6.2.2 Add Custom IP Filters Fill in the parameters described below and click “Add…”. Your entry should appear in the Custom IP Filters table on the bottom of the page. Note: Criteria are for inclusion by default. Select “exclude” if your criterion is for exclusion. Filter Number: Each IP filter is identified by a unique number from 1 to 20.
