Data availability

Remote management allows for one central processing site (server), to manage a collection of remote sites.Data transfers are live.Data can be buffered in case of central server loss.Since no intelligence is located on remote sites,

software upgrades are all executed on the central server.

Local management allows automated local site management, with a periodical reporting of gathered data to the central server.Data transfers are typically buffered.

Communication costs GPRS communications

↑Provides a dedicated connection to the site, when a local connection is not available

↓expensive:• Hardware: a GPRS modem is necessary,• Subscription: especially in some countries,

↓ can be unreliable• Not monitored or manageable by on-site personnel,

Local network connection ↑ Reliable: Internet connectivity problems are instantly detected

by on-site personnel. ↑ Inexpensive:

• A device can be added to the network to provide access to Wavenis devices

• A software can be installed on a local computer, in which case the cost is minimal (Wavenis modem installed on the computer).

Layers of architecture

An overview of components playing a role in the architecture.

Central server

Connections:Can accept incoming connection from otherwise

inaccessible remote sites.Can establish connections to accessible sites.

Manages network topologyStores information about which site a sensor is located

(defines which Waveport to use), and what relay route must be used in order to reach the sensor.

Manages logs and network health.Sites can be monitored:

• Based on the last reported activity in the case of on-site intelligence.

• Based on the connectivity status of the on-site Waveport.

Local gateway

Can be a dedicated platform:Waveport IPWaveport GPRSNitrobox

Can be a service running on an existing computer.

Accepts or establishes a connection to/from the central server.

Buffers data, or transparently forwards it as it comes.

Waveport

One Waveport = One Wavenis network

A large number of Waveports can be connected to one central server or local gateway, via:Physical connection: USB, RS232Network connection: local network,

internet, GPRS.
