Network Connection

The ORB can communicate with the Senquip Portal or a remote server via Wi-Fi or 4G LTE. Where both Wi-Fi and 4G LTE networks are selected, the ORB will first attempt to connect via Wi-Fi and if that is unsuccessful, the ORB will then attempt to connect via 4G LTE. In the event that neither Wi-Fi or 4G LTE networks can be found, the ORB can be set to log data to internal memory and then upload it when a network becomes available (see Endpoint settings).

Wi-Fi Specification

Wi-Fi on the ORB is used to transmit data, to allow settings to be remotely updated, to allow in-field software updates and also to enable setup via an integrated web-server that can be accessed in setup mode via a mobile phone or other Wi-Fi device.

The ORB Wi-Fi implementation supports Wi-Fi 802.11 b/g/n. The Wi-Fi antenna is integrated into the ORB. In typical applications, the range achievable with Wi-Fi is 500m.

4G LTE Specification

4G LTE on the ORB is used to transmit data, to allow settings to be remotely updated and to allow in-field software updates.

The ORB 4G LTE implementation is designed for global use and supports Cat-M1 and CAT-1 in the following bands:

Device	LTE Category	Bands
ORB-xx-G	CAT-M1 EGPRS	B1/B2/B3/B4/B5/B8/B12/B13/B18/B19/B20/B26/B28/B39 850/900/1800/1900MHz
ORB-xx-H	CAT-1 GSM / EDGE	B1/B3/B7/B8/B20/B28 B3/B8

The 4G LTE antenna is integrated into the ORB.

Connecting to a Wi-Fi Network

Once in setup mode, use the Network page to connect the ORB to a Wi-Fi network.

On the Network page, press the Scan for Wi-Fi Networks button. After a few seconds, a list of SSIDs for visible Wi-Fi networks will be shown. Select the Wi-Fi network to which you would like to connect by selecting the SSID from the list. The SSID will automatically be copied to the Wi-Fi SSID field and you will be prompted for the network password. After entering the password, press Save Settings. You will be prompted to restart the device; settings will only be applied after a restart. To continue with setup, press CANCEL or to restart and apply your settings, press OK.

Save your changes — Save changes and reboot

After a reboot, the ORB will attempt to connect to the specified Wi-Fi network. You can check if the ORB has successfully connected to the chosen network by placing the ORB in setup mode and returning to the Network page. At the top of the page, the current network status will be shown. Note the IP address that your Wi-Fi modem has allocated to the ORB; you can use this address to access the ORB directly on your WiFI network.

Check that you are connected — Note the IP address on your network

Further Wi-Fi settings are available by selecting the Advanced option. Once selected, a static IP address, netmask, gateway and DNS server can be specified.

The integrated web-server is normally only active in setup mode; it can however be made to be always on by setting the web setting to ON. This may be an advantage in systems where permanent power is available and the user wants to be able to make remote changes directly on the ORB without having to access the Senquip Portal. Keeping the web-server active will require that the ORB remain awake at all times but does mean that the user can make instant changes to settings and see the latest measured data.

When connected to a Wi-Fi network, the ORB may need to be able to make outgoing connections to remote services. To allow the ORB to make connections, some ports need to be enabled for outgoing connections on your Wi-Fi network.

Function	Port Number	Description
NTP Time	123	To be able to correctly timestamp measured data and for certain encryption functions the ORB needs to know time accurately. Time is accessed by connecting to an NTP server on this port.
MQTT to Senquip Portal	8883	Secure communications with the Senquip Portal are established on this port.
OTA update	80, 443	Over the Air (OTA) is a method by which the ORB software can be remotely updated. To enable remote software upgrades of the ORB software, outgoing connections need to be enabled on this port.

Wi-Fi Settings

A full list of Wi-Fi settings is given in the table at the end of the chapter.

Connecting to a 4G LTE Network

Once in setup mode, use the Network page to connect the ORB to a 4G LTE network.

In most cases only a 4G LTE network name and APN will be required to establish a 4G LTE connection. Some service providers will require a username and password and some SIM cards will require a pin. If these are not needed, leave them blank.

Once configured, press the check network button. If a connection is successful, the signal strength of the 4G LTE connection will be shown. Use the signal strength to optimise the mounting position.

RSSI	Signal Strength	Meaning
0	-113dBm or less	Signal strength poor
1	-111dBm	Signal strength poor
2…30	-109… -53dBm	Medium signal strength
31	-51dBm or greater	Signal strength excellent
