CHAPTER 1—INTRODUCTION Congratulations on your purchase of NETGEAR’s HE102 54 Mbps 802.11a Wireless Access Point, which gives you the ultimate in office mobility. This high-speed wireless device lets you quickly network multiple PCs and notebooks together without laying any new cabling, and gives users the freedom to roam throughout the workplace and stay connected to corporate resources, email, and the internet.
Features The key features of the HE102 Wireless Access Point are: ♦ Reliable IEEE 802.11a standards-based wireless technology. ♦ Interfaces directly to 10Mbps IEEE 802.3 Ethernet and IEEE802.3u Fast Ethernet networks. ♦ Roaming support between access points. ♦ Up to 72 Mbps high-speed rate in Turbo mode. Wireless nodes negotiate to operate in the optimal data transfer rate.
CHAPTER 2—WIRELESS NETWORK FUNDAMENTALS Wireless Network Configuration Ad-hoc Mode (Peer-to-Peer Workgroup) The Institute of Electrical and Electronics Engineers (IEEE) standard for wireless LANs (WLANs), 802.11 offers two methods for configuring a wireless network — ad-hoc and infrastructure. In an ad-hoc network, computers are brought together as needed; thus, there is no structure or fixed points to the network — each node can generally communicate with any other node.
In this configuration, network packets are directly sent and received by the intended transmitting and receiving stations. As long as the stations are within range of one another, this is the easiest and least expensive way to set up a wireless network. To set up an ad-hoc workgroup operating with standard protocols, do the following: ♦ Set all stations to connect in Ad-hoc mode (or Peer-to-Peer workgroup mode). ♦ Set all stations to use the same network name (or SSID).
To set up an infrastructure network operating with standard protocols, do the following: ♦ Set all wireless stations to connect in infrastructure mode ♦ Set all stations to use the same network name (or SSID). ♦ Set all wireless access points to use the same network name (or ESSID). For more information, please refer to page 7. ♦ Set all stations to use no WEP encryption key or an identical WEP encryption key as the one used in Access points.
A wireless LAN consisting of nodes operating in ad-hoc configuration without an access point is called a Basic Service Set (BSS). All nodes in a BSS must use the same Basic Service Set ID (BSSID). In an infrastructure configuration with access points, multiple BSS can be configured to form an Extended Service Set (ESS). In this configuration, the access points are configured with the same Extended Service Set ID (ESSID).
transmitted via the wireless interface. Some vendors may refer to the 40-bit WEP data encryption as 64-bit WEP data encryption since the actual encryption key used in the encryption process is 64 bits wide. The 128-bit WEP data encryption method consists of 104 configurable bits and the 152-bit WEP data encryption method consists of 128 configurable bits Similar to the forty-bit WEP data encryption method, the remaining 24 bits are factory set and not user configurable.
IEEE 802.11a uses Orthogonal Frequency Division Multiplexing (OFDM), a new encoding scheme that offers certain benefits over a spread spectrum in channel availability and data rate. The 802.11a uses OFDM to define a total of 8 non-overlapping 200 MHz channels across the 2 lower bands; each of these is divided into 52 subcarriers and each carrier is approximately 300 KHz wide. By comparison, 802.11b uses only 3 non-overlapping channels. IEEE 802.
The HE102 user can use eight channels in non-turbo mode. TURBO MODE: OFF Channel Frequency 36 5.18 GHz 40 5.20 GHz 44 5.22 GHz 48 5.24 GHz 52 5.26 GHz 56 5.28 GHz 60 5.30 GHz 64 5.32 GHz The HE102 user can use three channels in turbo mode. TURBO MODE: ON Channel Frequency 42 5.21 GHz 50 5.25 GHz 58 5.29 GHz Note: The available channels supported by the wireless products in various countries are different.
CHAPTER 3—INSTALLATION Installation Overview Please follow these instructions to successfully install your product. Estimated setup time is 10 to 15 minutes. 1. Determine the configuration of your wireless network. 2. Install the access point and connect it to your Ethernet network using the included Category 5 Ethernet cable. 3. Configure that computer to work with the access point and restart the computer. 4. Configure the access point. 5.
Please call the reseller or customer support in your area if there are any wrong, missing, or damaged parts. You can refer to the Support Information Card for the telephone number of customer support in your area. You should keep the Support Information Card, along with the original packing materials, and use the packing materials to repack the HE102 Wireless Access Point if you need to return it for repair.
Additionally, the HE102 Wireless Access Point supports the following wireless features: ♦ Distributed coordinated function (CSMA/CA, Back off procedure, ACK procedure, retransmission of unacknowledged frames ♦ RTS/CTS handshake ♦ Duplicate detection and Recovery ♦ Beacon generation ♦ Fragmentation and reassembly ♦ Authentication Algorithm (Open System, Shared Key) ♦ Roaming among access points on the same subnet LED Indicators The HE102 Wireless Access Point provides three green status LEDs: P
LED Power STATUS DESCRIPTION Off No Power On Power On Blink Off Green On Ethernet (Lnk/Activity) Green Blink Amber On Amber Blink Off WLAN (Link/Activity) Very Slow Blink Indicates: 1. running self-test, or 2. loading software, or 3.
Determine the Configuration of your Wireless Network Before installing the HE102 Wireless Access Point, you should make sure that your Ethernet network is up and working with a computer. You’ll be connecting the access point to the Ethernet network so that computers with the 802.11a Wireless Adapter will be able to communicate with computers on the Ethernet network. For each computer that you want to communicate with the access point, you must have an IEEE 802.
Note: Any access points configured to adjacent channels in the same vicinity will not interfere with each other. What is the WEP encryption key? _________________________________________ The absence of a physical connection between nodes makes the wireless links vulnerable to information theft. To provide a certain level of security from eavesdroppers and hackers, you can enable WEP encryption. The following information is needed to determine the WEP encryption level.
2. Connect the Ethernet Cable. You may use the included category 5 UTP Ethernet cable to connect the Ethernet port on the rear panel of HE102 Wireless Access Point to a 10 Base-T network hub, switch or router. 3. Connect the Power Cable. Connect the power cord of the HE102 Wireless Access Point power adapter to the 3.3V DC power socket on the rear panel of the access point. Then, plug the power adapter into an A/C power outlet.
CHAPTER 4—ACCESS POINT CONFIGURATION The HE102 Wireless Access Point can be configured remotely from either Microsoft I.E or the Netscape web browser on your computer. 1. Launch your web browser and enter the name of your access point in the Address or Location box. To find the name of your access point, refer to the labels on the bottom of your access point. The access point name should be similar to this, “netgear10d4b5,” where “10d4b5” is the last 6 digits of the MAC address of the HE102.
