About Teclo's optimization technology (see also "Teclo Networks Unveils Most Comprehensive TCP Data Optimization Product" - here):
"TCP/IP does not interact efficiently with radio networks. A few packets of data lost at the wrong time in a mobile broadband network leads to extended pauses in downloads and web page loading. This leads to frustration and dissatisfaction for the customer and more often than not a swift departure to another provider.Sambal has been measured to achieve 30% speedups in typical mobile broadband networks. This is achieved solely by optimising TCP/IP behaviour to make it operate much more effectively towards a lossy and high latency radio network"
