Retransmit On, Address Check On

In this case, an RF Address must be assigned to each M10. There are

numerous possibilities, depending upon how the RF Address is selected.

1. Multiple M10s, each connected via a single Ethernet card to a computer,

in a peer-to-peer wireless network. Each M10 should learn or be

configured with the attached Ethernet Card's 802 address to be used for

its RF Address. This network behaves (logically) as though the network

cards are connected by wire.

2. Multiple M10s, each connected via a single Ethernet card to a router, in a

multi-point wireless inter-network configuration. Each M10 should be

configured with the attached Ethernet Card's address used for its RF

Address. M10s should be placed on local router ports, rather than WAN

ports, which are restricted in data rate.

3. Multiple M10s, each connected via a single Ethernet card to a bridge, in a

multi-point wireless bridging configuration. Each M10 should be

configured with its M10 Address as its RF Address. The bridges must

have address bindings between the various Ethernet cards and M10s, and

the source and destination addresses must correspond to the M10s on

either end; (wired-side) frames would, of course, be encapsulated within

the frame delivered to the M10 by the bridge. The topology appears very

similar to that of #2 (the router configuration), but M10 Addresses must

be used.

4. Multiple M10s each possibly connected to multiple Ethernet cards (e.g.,

via 10baseT hubs), in a peer-to-peer network with RF Addresses assigned

for only selected card addresses (one per M10). For example, by assigning

the address of a server to the M10's RF Address it is possible to operate

the RF-MAC-level retransmission protocol for the server traffic, leaving

only lower-priority peer-to-peer traffic somewhat disadvantaged.

In #2 and #3 above, note that a router is a peer correspondent on each

network to which it is connected, while the bridge is a peer on none of the

networks. That is, a router is a source and destination on a network, using

its Ethernet card's unique 802 address; while the bridge uses its Ethernet

card's 802 address only for network control, but for normal traffic it uses the

original source address and the end destination address.

M10 USE OF 802 ADDRESSES

From the wired side, frames are uploaded to and downloaded from the M10 at

the AUI Port (AUI connector is attached, mating MAU connector is on the

M10). From the RF side, frames are transmitted from and received into the

RF Port. The destination address of each received RF frame is checked, if
