2 to reset to factory settings, u se the rese t function available through the web-scree n management module, or keep pressing the reset button located at the botto m of the device for 5 seconds. It has the following features: • Ethernet uplink WAN port • Local Ethernet LAN port (for configuration on ly) • Wireless (802.
3 802.11b The IEEE 802.11b standard, developed by the Wireless Et hernet Compatibility Alliance WECA) and ratified by IEEE, establishes a stable standard for compatibility. A user with an 802.11b product can use any bran d of access point with any other brand of client hardware that is built to the 802.
4 configured on the same subnetwork as the wired network interface and can be accessed by devices on the wired network. Possible AP Topologies 1. An access point can be used as a single AP without any connection to a wired network. In this configuration, it simply provides a stand-alone wireless network for a gro up of wireless devices.
5 Bridging A wireless bridge is an access point configured to allow wireless commu nication from access point to access point. The wireless bridging function in the WAB-1000 allows use as a wireless b.
6 SSID The Service Set ID (SSID) is a string used to define a common roaming do main among multiple wireless access points. Different SSIDs on access points can enable overlapping wireless networks. The SSID can act as a basic password without w hich the clien t cannot connect to the network.
7 3DES is modeled on the older DES standard but encrypts data three ti mes over. 3 DES uses more CPU resources than AES because of the triple encryption . MAC Address Authentication The MAC address, short for Media Access Control address, is a hardw are add ress that uniquely identifies each node of a net work.
8 Management After initial setup, maintenance of the system and programming of security functions are performed by personnel trained in the procedure using the embedd ed web-b ased management screens. The next chapter covers the basic proced ure for setting up the hardware.
9 Chapter 2: Hardware inst allation Prep aration for use The Level One WAB-1000 Outdoor Access Point requires physical mounting and installation on the site, following a prescribed placement design to ensure optimum operation and roaming.
10 Inst allation Instructions The WAB- 1000 inte nded to be instal led as pa rt of a complete wi reless d esign s olution. This manual deals only and specifically with the single WAB-1000 device as a unit.
11 The WAN port is used to connect the WAB-1000 to the organization’s LAN. The Ethernet cable is run from the WAB-1000 WAN port to the power injector which is then connected to a power source and the wired LAN. A second (LAN Port) Ethernet con nector is designed for use during initial configuration only .
12 Sealing Antenna Connections Once all antennas have been installed, th e connection should be sealed to protect them in an exterior harsh environment using a self amalga mating polyisob utylene tape which, over a period of hours, adheres to itself and forms a single amalgamated rubber molding confo rming to the shape of the item it is covering.
13 Chapter 3: Configure the W AB-1000 for use as an access point Introduction The WAB-1000 Gateway comes with the capability to be configured as an access point. It can be further configured for Bridging. This is discussed in Chapter 4. Configured as an access point, it allows one LAN to freely exchange data with another LAN without restriction.
14 Initial setup using the “Local” port Plug one end of an RJ-45 Ethernet cable to the LAN port of the WAB-1000 (see page 11) and the other end to an Ethernet port on your laptop.
15 NOTE: You will be asked for your user name and password. The default is " crypt o " with the p as sw ord " officer " to give f ull acce ss for s etup c onfigura tion.
16 Go next to the System Configuration—WAN page. W AN Click the entry on the left hand navigation panel for System Configuration-WAN. This directs you to the System Co nfiguration – WAN page.
17 If not using DHCP to get an IP address, input the information that the access poin t requ ires in order to allow the wireless devices it co ntrols access t o the wired LAN. This will be the IP address, Subnet Mask, Default Gateway, and, where needed, D NS 1 and 2.
18 Wireless Setup General Wireless Setu p allows your co mputer’s PC card to talk to the access point. Once y ou have completed wireless configuration, y ou can complete the rest of the co nfigura tion wire lessly if you wish, assuming that you have installed and configured a wireless PC card on your computer.

40 Chapter 4: Configure the W AB-1000 as a bridge Introduction In the WAB-1000, wireless b ridging uses a second WLAN card to set up an in dependent wireless bridge connection.
41 In the Wireless Configuration —Genera l screen, if you are setting up the WAB-1000 only as a bridge, the SSID can remain in its default setting , since the br id ge uses the BSSID for purposes of establishing contact. The BSSID is shown on the Wireless Configuration—Bridg ing page (see page 44).
42 The Wireless Configuration—Brid g ing Encr yption page is used to configure static encryption keys for the wireless bridge. This is an important page to set up to ensure that your bridge is working correctly.
43 The following sections describe the setup for three ty pes of bridg ing configuration: point-to- poin t, p oin t- t o - mu lt i po in t, or , last ly , re pea te r. Set up bridging type Point-to-point bridge configuration A point-to-point link is a di rect conn ection between two, and only two, locations or nodes.
44 For the two bridges that are to be linked to communicate properly , they have to be se t up with c ompatibl e comm ands in t he setup screens . For instance, the bridges mu st have the sa me channel n u mber. Because there is a separate WLAN card for bridging, there can be a separate WLAN on the 802.
45 Navigate to the Wireless Configuration —Bridging screen. In the first section: General, you will see the MAC address of the bridging card. This is used as the BSSID on other WAB-10 00 s that will be co mmunicating w it h this one. Wireless mode can be set to 802 .
46 enter only hexadecimal numbers, no colons. Data entry is not case sensitive. You m ay also enter a note that defines the location of the remote brid ge. Then click Add to accept. The remote bridge's BSSID will now appear in the third section of the page.
47 You must complete the configu r a tion of your Bridge 1 by foll owing the ge neral inst ruction s in Chapter 3 of this guide to establish any other required con figuration options such as General, WAN and LAN setting s. Configure the second of your two point-to-point bridges followi ng the instruc tions given f or Bridge 1 above.
48 bridging encryption of each must be set to the appropriate ty pe and key length and must be the same on all. Because the WAB-1000 has two separate WLAN cards, one for the AP card a nd one for the bridging card, each bridge can have a WLAN on the 802.
49 Wireless Con figuration – Brid ging Encryption Select appropriate key type/length and value. Must be the same key as Bridge 2~n. Select appropriate key type/length and value. Must be the sam e key as Bridge 1. The above recommended setup requires only Bridge 1 to be set in point-to-mu ltipoint mode.
50 BSSID Add Bridge 2's BSSID Add Bridge 1's and Bridge 3's BSSID Add Bridge 2's BSSID Wireless Conf iguration – Bridging Encryption Select appropriate key type/length and enter key value. Must be the same as that on the other 2 Bridges.
51 Chapter 5: T echnical Support Manufacturer ’ s S t atement The WAB-1000 is provided with warranty. It is not desired o r expected that the user open the device. If malfunction is experienced and all external causes are elimina ted, the user sh ou ld return the unit to the manufacturer and replace it w ith a functioning unit.
52 Glossary 3DES Also referred to as Triple DES , a mode of th e DES encryption algo rithm that encry pts data three ti mes. 802.11 802.11 refers to a fam ily of specifications developed by the IEEE for wireless LAN technology .
53 DHCP Dynamic Host Configuration Protocol, DHCP, i s a protoc ol for assigning dyn amic IP addresses to devices on a network. With dynam ic addressing, a device can have a diff erent IP addre ss every time it connects to the network . In some systems, th e device’s IP ad dress can even ch ange while it is still connected.
54 WPA WPA stands for Wi Fi Protected Access. It’s an interim standard developed by the WiFi Alliance pending full ratification of the 802.11i standard, to protect the wire d b and and impro ve upon the old WEP encry ption standard.
