Fujitsu Point 510 Radio Installation Guide

Overview

This document describes the configuration of the Fujitsu Point 510 with regards to the radio it is equipped with and the configuration of protocols and network clients. For complete information and instructions for the Fujitsu Point 510, please refer to the Fujitsu manual Point 510 Users Guide included with the unit. Note: The Fujitsu Point 510 is configured with a 2.4 GHz radio. The drivers for the radio are installed before the Point 510 leaves LXE. The radio is a Type II PC Card and occupies the only available PCMCIA slot. Upon installing the radio drivers for the unit a generic network protocol is configured for use with the radio. This protocol can be removed if necessary and another protocol can be added.

Radio Location

The Point 510 is equipped with a Proxim 2.4GHz radio. The image below shows the location of the radio.

Reinstall the driver or install the new version. Reconfigure the required parameters is described in the Radio Configuration section.

Radio Parameters

This section will describe the various radio parameters that can be configured by selecting the Proxim RangeLANPC Card Adapter from the list of network components and choosing Properties. Select the Advanced tab when the Properties window appears.

Channel

Note: The Channel parameter is NOT used when the Station Type configuration is set to Station. Each Master can select one of 15 Channels to establish communications with Stations. Each Channel number sets a unique frequency hopping sequence allowing for multiple subnetworks with higher data rate transmission capability in the same air space. You may think of the Channel as a pipe. In order to communicate, radios must be on the same Channel and there must be one (and only one) Master that provides the timing for that Channel. There are 15 independent Channels designated 1 through 15 with 1 being the default setting. This means that there are 15 different sequences of frequency hops. Each Channel is at a different frequency at a different time. For networks with multiple Masters (like in a roaming environment), set each Master to a different channel for optimum performance. You need only set the Channel on a Master or Alternate Master. Stations will ignore the parameter if it is set.

Domain

In order to establish communications, all Station Types require the same Domain number. Radios on different Domains cannot communicate with each other. The Domain is a software filter which does not affect the actual radio frequency or the frequency hop sequence. You may want to set everyone on your network to the same Domain. For larger wireless networks, use the Domain to establish roaming subnetworks throughout your building. For example, the Engineering Department may use Domain 2 and the Sales Department may use Domain 5. Then engineers can only roam within the geographical area mapped out by Access Points with a Domain setting of 2. The Domain is a number between 0 and 15 with 0 being the default setting.
Inactivity Minutes and Inactivity Seconds
To conserve battery life, the RangeLANcard has an inactivity sleep mode. The sleep mode is automatically engaged when a certain period of time has elapsed since the computer has sent or received data over the network. Once the card is asleep, it can be awoken by a Master station attempting to send data to it. However, if the sleeping machine is acting as the Master station, you will lose all communication on your network. Do not set an inactivity timeout on a Master station. The time before sleeping is calculated by adding the Inactive Minute and Inactive Seconds parameters and rounding to the nearest 5 second interval.

MAC Optimize

Note: The MAC Optimize parameter is NOT used when the Station Type configuration is set to Station.
This parameter can help improve throughput for small networks. If you have 8 or fewer wireless nodes communicating with a Access Point at the same time, set this parameter to Light. (You can have more than 8 nodes synchronized to a Access Point but only 8 or fewer communicating at the same time for the Light parameter setting). In networks with more than 8 concurrent wireless users, set the parameter to Normal or Auto. You need only set the MAC Optimize parameter on a Master or Alternate Master. Stations will ignore the parameter if it is set.

Master Name

Note: You need only set the Master Name on a Master or Alternate Master. Stations will ignore the parameter if it is set.
This optional parameter of up to 11 characters specifies an alphanumeric name to simplify the identification of each Master in your network. Spaces are not allowed.

Node Override

The Node Override field allows you to change the MAC address the RangeLAN2 card will broadcast during the current network session. If this field is not filled out or an illegal address is entered, the MAC address burned in at the factory will be used. Illegal addresses include multicast addresses and non-hexadecimal characters in the address. A multicast address contains an odd number in the second digit. For example, the address 010000000000, is a multicast address and an illegal value for a node override. When displayed on a network analyzer or the RangeLAN2 Windows 95 utilities, the address displayed will be that entered by the user but with bit 1 of the most significant byte set. For example, if you enter 000000000000 as the node override address, 020000000000 will be displayed as the node address. If you entered 040000000000, 060000000000 will be displayed as the node address. This is best understood when the digits are converted into binary. The digit 2 is represented as 10, i.e. bit 1 of the most significant byte is set. The digit 4 is represented as 100 in binary, so would be converted to 110 or 6 in decimal so that bit 1 of the most significant bit could be set. Note that this only affects the second digit of the MAC address. The Node Override parameter is only visible in Windows 95 and Windows NT, although MAC addresses can be overridden in the ODI and NDIS drivers using the Node Address parameter.

Peer to Peer

If the Peer to Peer parameter is set to Yes, wireless clients can communicate with one another. If set to No, the wireless nodes will only communicate with the Master unit. This results in a shorter synchronization time between the wireless clients and the Master unit. There are programs whose timings are inappropriate for wireless networking, resulting in the wireless nodes losing the network connection unless this parameter box is unchecked. You need only set the Peer to Peer parameter on a Station or Alternate Master. Masters will ignore the parameter if it is set.

Roam Config

The Roam Config parameter allows you to determine how quickly stations will roam from one Access Point to another. In areas with many Access Points providing heavy overlapping coverage, set this parameter to Fast to maintain high throughput for each of the wireless nodes. In most networks, set the Roam Config parameter to Normal. Wireless node throughput will not change noticeably, and an overabundance of Access Points is not required. If the wireless coverage area provided by Access Points is sparse, set the Roam Config parameter to Slow. Wireless nodes will note roam until the are nearly out of range of the Access Point. You need only set the Roam Config parameter on a Station or Alternate Master. Masters will ignore the parameters if it is set.

Station Type

In order for this system to work, in each subnetwork there must be one unit that coordinates the hops. This station is called the Master. It might help you to think of the Master as the conductor of a frequency hopping orchestra. The Master keeps time so all units know when to hop and what frequency to hop to. Units classified as Stations synchronize to the Master and follow its signal to learn what frequency in the pattern the Master is currently using. An acting Master can be configured either as a Master or Alternate Master. Alternate Masters act either as a Master or a Station. If an Alternate Master unit is unable to locate any other Master within range, it acts as a Master. If a Master is already present, then the Alternate Master acts as a Station. When there are multiple Alternate Masters, they coordinate amongst themselves to determine who will become the Master. There must be at least one station on the network designated the Master. For most network operating systems, the LXE 6430 Access Point should be the Master and all clients are defined as Stations. In a roaming environment, all Access Points will be configured as Masters. The RangeLANclients are all configured as Stations and roam from one Master to another. You will want to set as few machines as Alternate Master as possible to increase performance. The checking the system does to see if it needs to become a Master adds overhead to the wireless traffic.

Subchannel

The Subchannel is a software code that is appended to each radio packet. It does not affect the frequency hopping sequence like a Channel does. Use a Subchannel if you need more than 15 Masters in the same area and, therefore, all the Channels are used. For example, you can use Channel 1, Subchannel 1 for Network A and Channel 1, Subchannel 2 for Network B. The two networks will not communicate with one another. They are, however, still sharing the 1.6 Mbps pipe since they are both using Channel 1. The Subchannels are designated 1 through 15 with 1 being the default setting. You need only set the Subchannel on a Master or Alternate Master. Stations will ignore the parameter if it is set.

In this position paper we argue that electronic book and document readers (HUHDGHUV) open new avenues for computer supported collaborative work. This position draws on our experience building and e-reading with the XLibris active reading machine, a portable pen-based computer specialized for the task of reading, critical thinking, and analysis.

KEYWORDS

Electronic book, electronic reader, e-reader, reading appliance, computer supported collaborative work.

INTRODUCTION

)LJXUH 7KH ;/LEULV (5HDGHU platform for a new class of computer supported cooperative work applications. Here we present five visions of how collaborative work might change with the introduction of e-readers. Each idea starts with the free-form ink marks that people naturally make as a part of their work with books and documents and adds computation and communication to make these marks more useful in a collaborative setting. The first two cases explore different aspects of using e-readers in the course of common document activities: reviewing/revising and discussing. The last three amplify positive effects that arise in paper document work: serendipitous sharing of marginalia, identifying passages of common interest, and discovering people with like interests by what they read.

WRITING AND REVIEWING

During the last two years we have been investigating how electronic book and document readers (HUHDGHUV) can augment knowledge work. The paper-document metaphor we designed for our XLibris research prototype1 (Figure 1) imitates the physical experience of working with paper: readers hold an electronic page in their lap, moving the ereader to avoid glare; mark with various pens and highlighters; and riffle through an electronic document. Beyond imitation, XLibris uses computation to augment existing analytic reading practices, such as searching for related documents, organizing your readings, and skimming for important information [2]. XLibris and other e-readers create exciting opportunities for collaboration not possible with previous interfaces. This is because e-readers blur the distinction between paper and computer work. People easily collaborate over paper books and documents everyday in all sorts of ways, yet people are limited to passing and faxing paper around. On the other hand existing computer-based tools provide many benefits for collaborative work, yet they often get in the way. By combining the ease of use of paper with the computation and communication of computers, e-readers are a unique
How do writers collaborate? They create documents and circulate them for review. Typically, reviewers are handed paper documents to mark up, return, and sometimes discuss. In the end the writer revises the text while referring to the marked-up drafts. How might writers and reviewers collaborate over e-readers?
The writers point of view
XLibris is hosted on commercial pen computers including the Fujitsu Point 510: 3.9 lbs.; 2.1 GB disk; 800 x 600 SVGA color display; 1.6 Mbps spread spectrum wireless LAN.
Writers often receive comments from more than one reviewer. Revising a document by integrating the comments from multiple reviewers is awkward. The writer is forced to
navigate among multiple marked-up paper copies as well as the online version under revision. Because they support free-form markup, e-readers can electronically record and later present comments from multiple reviewers so that the revisions can be easily integrated. The comments can be presented to the writer all at once, in a single draft (perhaps in different colors). When multiple comments in a passage interfere with each other, the writer might ask to selectively show or hide certain reviewers comments (e.g., hide all of Cathys scrawls).

The reviewers point of view
by the marks themselves. On the other hand, if a person borrows a paper from a colleague she respects, she may value even a simple underline or an exclamation point in the margin. Anonymity and reciprocity are issues that need to be addressed by designers of systems that share electronic book annotations.

BUILDING CONSENSUS

On the way to producing a final document, reviewers are asked to comment on several revisions. When reviewers do this, they ask themselves: Didnt I comment on this last time? How has this changed? Change bars and online markup (ala Microsoft Word) can help answers these questions, but force the reviewer and writer to use the same text-editor interface for making and responding to comments. This isnt a problem for the writer, but people prefer making free-form ink marks when reviewing. Using an e-reader, a reviewer can still use free-form ink to markup a document, but can also use the computer to help compare the versions. In this case, Cathy can say: ditto on that same comment I made last time!
USING THE PAGE TO FOCUS A DISCUSSION
Annotations on paper documents and books reflect a readers unselfconscious engagement with the text. Freeform annotations on e-readers enable this same sort of engagement with digital media. The question then becomes: Can we parlay these marks into something more? How can free form annotations become a resource for a community of annotators focused on the same document? If we examine the kinds of marks that readers make, there is great variability among individuals. However, one thing is clear: the annotations, highlights, and other marks demonstrate a readers focus. By looking at ZKHUH people mark, rather than KRZ they mark we can find areas of consensus: places in the text that all or many of the readers found sufficiently important to mark [1]. This view can then be used to create summaries based on a group reading, or can focus a group discussion in, for example, a face-to-face meeting or distance-learning classroom. This way, readers not only know what the author found important (through structural or typographical cues like topic sentences or boldface text), but also what RWKHU UHDGHUV thought remarkable.

BRINGING PEOPLE TOGETHER

When people work with documents, they crowd over the page, pointing at and marking on text. What happens when people arent co-located? They might fax the document back and forth and discuss it over the phone, but they lose the sense of shared focus that comes from face-to-face interaction. Or they might give up, turning the desired tightly focused synchronous collaboration into an asynchronous exchange. With e-readers people can crowd over a shared page even when they are not co-located. The e-reader might present marks or a cursor from other e-readers and synchronize page navigation. Free-form ink is a natural means for a group to work on a document [3].

SERENDIPITOUS SHARING

The books and documents we read along with the ink annotations we make on e-readers create a new way to identify potential collaborators. For example, you have expressed interest in finding collaborators in your work. You are reading and marking-up a company report on lowemission vehicles and your e-reader notifies you that someone in manufacturing has been reading the same report, they are also interested in nitroglycerine fuel cells, would you like to send e-mail? A system for connecting people may work best with a TXLG SUR TXR arrangement: you must publish your reading and annotation data before you can search other peoples reading data for collaborators. Bringing together people with similar interests and goals DV WKH\ SHUIRUP NQRZOHGJH ZRUN can be extremely powerful. The key advantage of e-readers is taking peoples existing practice of making marks and then inferring interest and matching one persons reading interests to another. Of course docu-dating might prove valuable for non-work situations as well: the attractive blond at the end of the bar also reads lawyer-drama fiction.

CAVEATS

Paper documents and books pass from hand to hand. The marks people have made on the documents travel with them, seamlessly, without the intentional act of publishing the annotations (as most shared annotation systems demand). How will electronic books and the facility to mark in them play into this practice? Can we take advantage of how marks on paper are unintentionally shared? The marks that readers make are not universally valuable or intelligible [2]. Nor is their status unambiguously public or clearly private. A used book may have valuable (or annoying) markings that have been rendered anonymous if they are resold by a third party (a bookstore, for example). The reader has no real way of assessing their worth except
E-readers exist within a broader setting of work and technology, something that designers of e-reader supported cooperative work must account for. In particular, the e-reader will likely be used in tandem with paper and traditional

desktop computers. Also, documents are used in ways beyond just conveying information; placing a paper on your boss keyboard is different than putting it in her mailbox. Finally, as with most CSCW technologies, collaborative ereading will require up-front social negotiation about privacy and reciprocity.

We use paper books and documents in our daily collaborations. E-readers have the potential to enhance these paperbased collaborations and also to create new opportunities and ways of working together. In this position paper we focused on peoples free-form ink marks as the principal means for initiating collaborative activities with little additional overhead. Collaborative practices using paper books and documents are rich, complex, and varied, and invariably e-reading will increase this diversity. This position paper has explored but a few aspects of how e-readers may help us collaborate.
