CLARION MERLAN M10

INTRODUCTION

The Clarion MerLAN M10 is a wireless transceiver providing 10 Megabits/sec

burst data rate to support wireless connections in IEEE 802.3 and Ethernet II

LANs. The MerLAN M10 functions as an Ethernet Medium Attachment Unit

(MAU). The Medium Access Control (MAC) frame from a standard

Attachment Unit Interface (AUI) port is encapsulated to form a Radio

Frequency (RF) MAC frame. It uses the state-of-the-art spread spectrum

technology to implement robust 10Mbps burst transmission. It also manages

the efficient utilization of frame buffers and coordination of the RF and wired

interface traffic to maintain this high throughput. In addition, the unit offers

true “Plug and Play” installation; no additional driver software is required for

its operation. That is, the MerLAN M10 can be connected to not only a

computer, but also to router. In certain configurations and topologies, the

unit can also be connected directly to a bridge or hub. Accordingly, you can

create various kinds of innovative LANs combining existing wired devices

and the Clarion MerLAN M10 units.

PRODUCT OVERVIEW

The Clarion MerLAN M10 is a combination of hardware and firmware

providing 10 Mbps data rate over a wirless medium using state of the art

direct sequence spread spectrum radio technology in the 2.4 GHz radio

frequency band. Utilizing forward error correction, re-transmission protocol,

flow control, and continuously changing spreading codes, the MerLAN M10

provides a fast, safe, secure, and robust wireless transmission. A Windows 3.1

based configuration utility program enables the MerLAN M10 to be fine

tuned to integrate seamlessly into your existing network environment

preserving your current resource investment. The configuration options

provide network connectivity directly to personal computers, routers, bridges,

and hubs.

DATA TRANSFERS

A data transfer is called an Upload when the ethernet device conveys a

frame from itself to the MerLAN M10’s buffered memory through the MAU

port. The buffered memory is organized as 16 2K byte FIFOs with each
