Chapter 1 - Introduction

Roaming Between SpaceLink™ Gateways or APs

If there are multiple SpaceLink Home Gateways or Access Points on the

network, then a wireless mobile client may seamlessly roam from one the

SpaceLink Home Gateway or Access Point to another.

Each SpaceLink Home Gateway or Access Point creates its own wireless

cell or coverage area. This is also known as a Basic Service Set (BSS). Any

wireless mobile client can communicate with a particular SpaceLink Home

Gateway or Access Point if it is within the SpaceLink Home Gateway's or

Access Point's coverage area.

If the cells of multiple SpaceLink Home Gateways or Access Points overlap,

then the wireless mobile client may switch from one SpaceLink Home

Gateway or Access Point to another as it travels throughout the facility.

During the hand-off from one SpaceLink Home Gateway or Access Point

to another, the wireless mobile client maintains an uninterrupted connection

to the network. This is known as "roaming."

Multiple SpaceLink Home Gateways connected to a common Ethernet

network form an Extended Service Set (ESS). All members of an Extended

Service Set are configured with an ID, known as the SSID or ESSID.

Wireless mobile clients must be configured with the same SSID as the

SpaceLink Home Gateways or Access Points on the network; a client can

only roam between the SpaceLink Home Gateways or Access Points that

share the same SSID.
