Broadband Maritime VSAT Flat Rate versus Pay-by-the-Byte Services

2way2sat Broadband Maritime VSAT services are offered for a flat monthly fee. MSS are pay-by-the-Byte / -Minute systems, i.e. the height of the monthly invoice depends on the consumed air time.

The following features differentiate 2way2sat Broadband Maritime VSAT from existing Maritime Satellite Services (MSS) with lower bandwidth solutions:

Pay-by-the-byte services can certainly meet basic voice and telecommunications requirements. However, they are not cost effective in applications such as web surfing, streaming video, or transmission of e-mail attachments larger than a few hundred kilobyte. Pay-by-the-byte services are suitable for voice, e-mail, SMS, transmission of low resolution pictures and small files. When using bandwidth saving protocols like SSH they can also be used for remote management of PCs and IT infrastructure onboard.

However, whoever plans to give crew members or passengers of ferries and cruisers access to the Internet definitely needs a fixed priced broadband VSAT service. This is one of the reasons why demand for atrexx’ 2way2sat Broadband Maritime VSAT services is rising rapidly.
