SPEEDLAN Plus & 10 ;

WaveLAN Network ID (NWID) - The Network ID assigns a number used to identify the transmission an interface. In order for another wireless interface to receive the transmission, the interface must be a match Wave Wireless Networking product that has the same Network ID assigned to it, otherwise the transmissi will be discarded. This adds to the inherent security of Spread Spectrum technology by encoding the transn sions in such a manner that wireless traffic cannot be intercepted without matching Wave Wireless Network equipment and the exact Network ID that you assigned to the SPEEDLAN interface. WaveLAN DES Encryption Key - This option will only be available on SPEEDLAN equipment purcha with the DES Data Encryption package. The Data Encryption package allows further security of the transr ted data. The DES Encryption Key must be the same on all brouters expected to transmit data to or rece data from this interface. WaveLAN Receive Threshold - The WaveLAN Receive Threshold functions in a similar manner as Squelch Knob on many 2 way radio systems. Increasing the value of the threshold reduces the sensitivity of receiver. Increasing the value of the threshold would be used to filter out lower level signals that may interfering with the performance of the receiver. This setting should be changed in small increments until desired threshold is acheived, setting this value too high can result in the receiver not being able to detect transmissions of its partners slowing the performance of the unit, or rendering the brouter inoperable. Enable External Antenna Support - This setting is required for all installations that require the use of external antenna. Disabling this setting may damage the brouter. Enable Continous Signal Quality Tests - If continous signal quality tests are enabled the brouter will s special test packets at the rate of one per second. This is helpful because with these tests enabled any receiv station will keep statistics on its ability to receive from this station. The cost for this feature is that the t packets will use a small amount of RF air time. If you have a few wireless stations this is inconsequential. If}

have dozens of wireless stations in your wireless cell and all of these stations are transmitting test packets brouters will be severly hindered. Transport Methods The industry compatible method of transmitting and receiving data over wireless networks cause data pack to frequently be lost. This is due to the fact that a wireless network does not have the ability to detect collisi like a wired Ethernet network. On an Ethernet network collisions can be detected by the hardware and automatically retransmitted. Ethernet is refered to as CSMA/CD (Carrier Sense Multiple Access with Cc sion Detect). Wireless networks are CSMA/CA (Carrier Sense Multiple Access with Collision Avoidan:

The reason collisions can not be detected is wireless cannot receive and transmit at the same time, he:

SPEEDLAN is not able to listen for the collisions. In practice a properly operating SPEEDLAN point-

point network will loose, due to collisions, less than 1% of the transmitted packets. This packet loss is normally a problem with protocols such as Novell IPX (without the Burst Mode NLM) but may cause r works using most other protocols to experience poor performance. Campus Cell PRC helps to alleviate t problem by placing multiple packets into one larger packet, thus saving bandwidth by eliminating the e overhead. 28 SIFPEEMECOM Wh? =) WIRELESS INTERNATIONAL WIRELESS NETWORKING

Each Wave Wireless product is warranted against defects in material and workmanship for a period of one year from date of shipment. During the warranty period Wave Wireless will, at its option, repair or replace products that prove to be defective. If equipment fails, the Customer or Reseller shall notify Wave Wireless and request a Return Material Authorization (RMA) number. For warranty service or repair, this product must be returned to Wave Wireless. All returns to Wave Wireless MUST have a valid RMA number written clearly on the outside of the box or the shipment will be refused. The buyer shall pay all return shipping charges during the one-year warranty. All outbound shipments will be made via ground shipment by Wave Wireless or via air courier with the customers account number with the exception of Extended/Spare in the Air Warranty holders. Extended Warranty Policies (Includes Spare in the Air) At any time during the first year following an equipment purchase, an Extended Warranty Policy may be purchased for 10% of the original list price. Terms of the Extended Warranty include Spare in the Air privileges to allow the use of parts or a spare unit temporarily. Spare in the Air Loaner Unit or Parts Replacement Policies For an additional 10% of list price, the customer may purchase a Spare in the Air policy. This policy gives the customer the right to a loaner replacement unit shipped within 24 hours of acceptance of the RMA by Wave. All outbound shipments will be made via overnight air courier (during the first year). Spare in the Air Policy Steps for Warranty or Extended Warranty Loaner Service:

1. Customer obtains RMA approval 2. Overnight shipment of spare unit or parts to customer within 24 hours of approved RMA. Customer swaps unit or part(s) with phone assistance, if required. 3. Customer returns part(s) to Wave Wireless. All returns to Wave Wireless MUST have a valid RMA number written clearly on the outside of the box or the shipment will be refused. 4. After 14 days from the issuance of an RMA, an invoice for the list price of the unit or components will be issued for any equipment that has not been returned. This will be credited upon the return of the defective or replacement part or unit to Wave Wireless. Extended Warranty Pricing Schedule 1* year: 10% of published equipment list price 2 year: 15% of published equipment list price 3" year: 15% of published equipment list price

*If all three years are purchased simultaneously, the cost will be 10% per year or 30% of list. Years 2 & 3 can be purchased during the initial year of coverage if the equipment was under extended warranty during the first year or if a physical on-site equipment inspection is performed and equipment is evaluated in warrantable condition by Wave Wireless personnel at prevailing or site service call rates. Onsite Services Onsite services for troubleshooting and repair are billed at daily rate, plus expenses, unless otherwise agreed upon. Use of spectrum analyzers or other test equipment may raise the daily rate. Rental Unit Loaner Customer may rent a unit at an agreed upon daily rate, plus shipping expenses, in lieu of purchasing a spare or Spare in the Air policy. Rental days are counted from date shipped until the date the unit is received in return by Wave Wireless.
