Wireless LAN is local area networking without wires It uses radio frequencies to transmit and receive data between PC’s or other network devices. 802.11b Wireless LAN is able to configure independent networks and infrastructure networks. The former is suitable for small or temporary peer-to-peer configurations, and the later is offering fully distributed data connectivity via micro cells and roaming.

TELLUS Access Point/BRIDGE             Price:     NZ $250 plus gst

             APPLICATIONS

• Home networking for device sharing - Remote access to corporate network information email, file transfer and terminal emulation.
• Frequently changing environments - Retailers, manufacturers and banks that frequently rearrange the workplace and change location.
• SOHO (Small Office and Home Office) users - SOHO users need easy and quick installation of a small computer network functions.
• Inter-building connection - The wireless building-to-building network installs quickly, requires no monthly lease fees, and provides the flexibility to reconfigure easily.
• Typical applications include hard-to-wire buildings, campuses, hospitals/medical offices, warehouse, security huts, exhibition centres, etc.
• Temporary LANs for special projects or peak time - Auditors require workgroups at customer sites. Trade shows, exhibitions, retailers, airline, and shipping companies need additional workstations for a peak period.
• Enable the connection of high speed internet services eg jetstream where it is normally inaccessible ie transmit it from point to point office in town to home some Kms away

PCI       adaptor and card

This plug and play unit inserts into a PCI slot inside  the IMB compatible PC . It comes with PCI interface software and PCMCIA card software  .The PCMCIA card is now hot swappable and accessible through the rear of the computer  The PCMCIA cards are available in two models.

1. The internal antenna type and the version with a SX  external antenna   socket . This card in association with  the external remote 5 dBi Omni directional antenna gives good reliable consistent performance  and greater range than the internal antenna within the 'card, can provide . It is the combination of choice for a desktop computer

                        .

PCI adaptor card and PCMCIA  wireless network card card   NZ$ 280 plus gst

                                 PCMCIA Card only                                    NZ$ 100 plus gst

   5 dBi  Omni directional antenna with sx connector  NZ$  90 plus gst

2     The PCMCIA card without the external antenna socket, for use in the more mobile situation i.e  the use of a roving Laptop  prohibits the application of the external antenna .

There is no reason why the above card with antenna socket shouldn't be used in the Laptop if you don't mind having to attend to the small cabled antenna should you be moving around . This antenna addition can increase range and performance by potentially providing    stronger signals.

Setting up the Tellus Access Point.

The Access point can be addressed via  ethernet  cable connection using an IP address assigned  within the unit and/or  USB connection from the back of a PC capable of USB operation. The AP is supplied with software on CDROM to enable both methods.

IP Method :Set up the AP via a network connection> Install the Tellus supplied software from the   CDROM . Set up your 10/100  network card with the TCP/IP protocol ,   and  make sure that both your PC and Access Point are at the same domain, i.e. the first three fields of the IP address. The factory setting of Access Point IP address is 192.168.1.100. Make sure your pc has and IP address of 192.168.1. X       (where x can be from  1 to 254)        How ever you may change the IP address either on your PC or Access Point to make them register  the same domain. (you could do that via the local usb interface) . Make sure the units have separate IP addresses , the same subnet mask address , ESSID must be the same ,The same channel, "Disable WEP" to start with, set Authentication type to "open system",  give each Access point its own name for identification purposes,  set the Operational mode to "Access Point" and the other unit to "Access Point client", set the Primary port of unit with the Ethernet cable connected to your computer as "Ethernet" and the remote unit  port as "wireless", make sure Authorisation algorithm is "disabled" .  that should enable you to have two units IP address appear  on the SNMP screen after you click  "find AP" . Once you get the two units showing up, then you can play around adding WEP etc NOTE:  There are some "security" parameters that can only be changed by USB .

Start the program  called TWL-A11 ,then SNMP Manager .   (small network management protocol) click on File , Find access point, after about 3 seconds the access point will appear ,double click on the access point you want to examine (there should be more than one available in a large wireless network but you may see only one so check the settings of the remote units PORT setting) type into the space provided the word password      "public"    and select "administrator"  before clicking OK. (click "user" and you can only look at settings and cant modify them) If the SNMP  is successful, you will see lots of selectable options appear on the top line of the SNMP window, these are...File, setup, commands, info, traps network, window and  help.     Click on each one to examine where it takes you but don't change anything  yet. You enter the Operational Mode by clicking Setup, Wireless LAN, Operational Settings of SNMP, and Advanced, choosing the Wireless Bridge.   Can I suggest you get the two units running as  two AP  set one to "Access point client" and one as "Access" point only , one must be master and one slave!

                                          Two options are available, one is the Point to Point and the other   is the Point to MultiPoint. For  Point to Point, the Wireless Bridge can communicate with a specific Remote MAC Address. (You need to define the Remote MAC Address, which corresponds to the MAC Address of the Wireless Bridge of the Remote LAN.)     For the remote "point to multipoint" unit to be seen from the "far end" using the SNMP, its primary port( via USB  AP utility) MUST be set from "Ethernet"  to "wireless"        For the Point to Multipoint, the Wireless Bridge can communicate with any Wireless Bridge available in the same channel. However when "Authorised Algorithm" is enabled, the Wireless Bridge can only  communicate with any Wireless Bridge whose MAC Addresses exist in the Authorisation Table. This increases the security of the system and minimises the possibility of unauthorised access. (note I said minimises, it will not prevent those wishing to hack into you system! ( see WEP)    When running other than TPC/IP,   set the IP Filtering of  the TWL-11A  to "disable" (Setup -> Bridge -> Filtering.)  You may use AP Utility or use SNMP to configure the Identifier of IP Filtering to disable  . Please note that setting the IP Filtering to "disable"  may degrade the network performance when you are running TCP/IP. Before leaving the SNMP screen go to "File" and click on "download changes" ,then go to Command and select "Reset ". if you get a reset failure (see bottom of screen left)   you can try a number of times more , if this keeps occurring , if possible unplug the power to the AP unit and let it reboot to effect the  configuration changes.                                                                                                 USB Method: This can only be done locally via a suitable pc with usb support and the correct TELLUS supplied software . The exact same information and available parameters are available with USB configuration , except it is in listed format.   Save your changes after modifications  this takes 10 seconds or so to implement.   Dont forget to "Reset AP"   to effect  the parameter changes.

This should be enough to get your system running you can now modify configurations to enhance performance set WEP etc  write down the settings that you change because if you come unstuck you can at least backtrack to a setting that provides communication.

APPLICATIONS

The range of the Wireless Lan systems can be extended greatly by the use of directional gain antennas, At Pinfold Health Services, we stock a range of antennas cables and connector adapters  made for outdoor use that will enable this .You may have a business contained in two separate buildings,  separated by distance eg  across a public road and it may be prohibitive to connect you computer system directly by cable, so you have to rely on the local telecommunications company to lease you expensive data lines.                    . Why not install a pair of TELLUS  AP units configured as LAN bridges, connected to small parabolic  antennas at each end and beam the signal over a line of sight path to interconnect your business. Why pay exorbitant fees when you can connect for free!!?                                                                                                                                                                            Haven't got ADSL at home or at the other premises??  you'd love to have it available, but ADSL  is not in you neighbourhood!? why not have it installed somewhere where it is available and beam it by TELLUS wireless  LAN to you. Not line of sight between ends ??   Tellus Access points are able to operate as data repeaters  so you can install one at a common visual point and still obtain connection provided the distance is no too great (ask us about this I've done it for my home internet there was no ADSL available in my area!! 5 km path too!)

Tellus wireless Lans can be used for a multitude of purposes where computers and digital signals are concerned.   security systems ... send sound and video from a security camera and computer at a remote site ??.   Let you imagination run wild!      I'm sure they will solve a problem for you!
