Customer Premises Equipment for Tooway Satellite Internet
To establish a high-speed satellite internet connection, a specific set of hardware known as Customer Premises Equipment (CPE) is required. This system is divided into two primary components: the Outdoor Unit (ODU), which handles the wireless communication with the satellite, and the Indoor Unit (IDU), which manages the data flow within the home network.
The Outdoor Unit (ODU)
The ODU consists of a parabolic satellite antenna, typically 60–70 cm in diameter and manufactured by ViaSat. A standout feature of the ViaSat SurfBeam antenna is its frequency selective sub-reflector. This specialized component allows the antenna to be transparent to one frequency range while reflecting another, enabling a single ODU to handle both interactive services in the Ka band and Direct-to-Home (DTH) broadcast services in the Ku band.
Installation and Alignment
Installing the ODU involves automated tools to simplify commissioning and alignment. The process is standardized across the satellite service area, and the use of circular polarization—a method of transmitting electromagnetic waves in a spiral path—further reduces installation time and costs.
Precise alignment is critical; poor positioning leads to higher error rates and reduced broadband speeds. Because the system uses a unique Turbo Code 8PSK transmission system, standard DVB-S or DVB-S2 installation meters cannot be used for alignment. Specialized tools are required, such as the Horizon Global Electronics meter or the Applied Instruments Super Buddy 29. However, these older meters do not support newer Viasat SurfBeam DVB-S2 signals.
For higher capacity signals and Ka band frequencies, accuracy is even more vital. The SAM-plus meter from Maxpeak AB (publ) is specifically designed for these DVB-S2 ACM and VCM signals. Additionally, the current KA-SAT Surfbeam TRIA (the dish receiving block) includes a built-in audible tuner, allowing for accurate pointing without an external meter.
The Indoor Unit (IDU)
The IDU is a satellite modem manufactured by ViaSat that serves as the bridge between the satellite signal and the user's local network. It provides a plug-and-play Ethernet interface using DHCP (Dynamic Host Configuration Protocol), which automatically assigns IP addresses to connected devices.
While no specific software is required on the user's computer, a WiFi router can be connected to the modem to provide wireless access throughout the home. It is important to note that as of mid-2012, software updates disabled DHCP within the modem itself. Consequently, subscribers using more than one device must provide their own router with a DHCP server to manage network connectivity.
The front of the modem features LED indicators that provide real-time status updates on satellite reception (RX), transmission (TX), and general network activity. The IDU is linked to the ODU via two coaxial cables.
Key Facts
- Hardware Components: Consists of a ViaSat ODU (antenna) and an IDU (modem).
- Dual-Band Capability: Supports Ka band for interactive services and Ku band for broadcast services.
- Antenna Size: Typically ranges between 60 and 70 cm in diameter.
- Alignment Tools: Requires specialized meters (e.g., SAM-plus) or the built-in audible tuner in the TRIA block.
- Connectivity: The IDU and ODU are connected by two coaxial cables.
- Network Requirement: A separate DHCP-capable router is required for multi-device setups due to 2012 software changes.

Frequently Asked Questions
Can I install the Tooway dish myself?
While advanced users may be able to perform the installation, it is recommended to use a certified Tooway installer. Poor alignment can significantly degrade broadband speeds and increase error rates.
Why can't I use a standard DVB-S2 meter for alignment?
Standard meters do not recognize the unique Turbo Code 8PSK transmission system used by Tooway. Specialized meters like the SAM-plus or the TRIA's audible tuner are required.
Do I need special software on my computer to use the internet?
No, no specific software is required on the computer to connect to the service.
Why do I need my own router if I have multiple devices?
Due to software changes implemented in mid-2012, DHCP was disabled in the modem. A separate router with a DHCP server is necessary to assign IP addresses to multiple devices.
How is the indoor modem connected to the outdoor antenna?
The IDU is connected to the ODU using two coaxial cables.
