What Satellite can and cannot be used for

What Satellite Broadband Can And Cannot Be Used For

Application Operation via Satellite Recommendations / Limitations
HTTP (web) browsing

 

Works very well
TV on demand such as BBC iPlayer Works very well NB: data allowance limitations an SD film use 0.75 GB HD film 4.5GB
Facebook, LinkedIn and other social media sites Works very well
FTP and TFTP applications Works very well
Video on demand such as love film & Netflix Works very well NB: data allowance limitations an SD film uses 0.75 GB HD film 4.5GB
Internet Radio Works very well NB: data allowance limitations 8 hours of internet radio will use 1GB
Citrix (Thick Client) Operates but some issues are known Citrix acknowledge the adverse effect of high latency links on their Application. Three options must be utilised to improve Citrix operation (SpeedScreen, Bitmap Caching &Mouse & keyboard queuing)
Citrix (Thin Client) Works Well A Citrix engineer should be consulted prior to its use over satellite to optimise the timeout parameters on the server.
SSL VPN Works very well Unfortunately SSL VPN encryption only works for Web-based applications, therefore cannot allow secure file transfers from a Data Centre or FTP sever
IPSec VPN Works but limited to typically 150kbps or lower per TCP session IPSec is a more secure encryption method than SSL enabling full Packet encryption. This however renders all satellite network Accelerators and Optimisers ineffective. BT provides a satellite friendly IPSec & WAN Optimisation VPN overlay Product for Corporate solutions.
Interactive online gaming.

 

Works with limitations It is not recommended to play so called “first-person shooter” games. Any kind of combat or game that involves the need for an immediate reaction will not work so well just due to the extra time involved in the trip to the satellite and back that your data has to make.
You Tube video viewing and sharing

 

Works very well NB: data allowance limitations a 5 Min Video Clip on YouTube will use 0.1GB
IMAPI e-mail (Microsoft Exchange server etc.)

 

Works with noticeable delay Newer versions are continually improving the chatty protocol causing the lowered performance. An IT engineer should be consulted re possible alternative solutions to improve performance.
Web mail access to e-mail IMAPI servers Works  very well
POP3/SMTP email Works Well Check with existing ISP that customer can access their current email address from a different network than their current ISP, and the setting required to set up their email client.
VoIP Work with limitations Customers are welcome to use VoIP but there is no guarantee that Voice quality will be maintained throughout the call.
Skype Work with limitations Skype utilises the Peer 2 Peer protocols therefore will function but similarly to VoIP performance of the call (Voice and or Video) cannot be guaranteed.
Database Applications Work with limitations Large database transfers are accelerated. But not queries or directory synchronisation. A Database engineer should be consulted prior to its use over satellite to optimise the timeout parameters on the server.
Terminal emulators Work with limitations Must have local-echo enabled at the remote site in order to perform properly
Shared desktop TCP acceleration helps with bitmap files of screen images,
FTP & TFTP Works very well
NetBIOS

 

Does Not function This is a LAN technology that cannot be accelerated as it is not a routable function in a WAN environment.
Shared drives or Drive-mapping

 

Works with very noticeable delay Is not recommended over satellite except through a VPN tunnel. An IT engineer should be consulted re possible alternative solutions to improve performance. E.g. Web based Portals or WAN Optimisation.
Wireless Access Points Works very well Customer will need to purchase their own wireless router and these devices are available from most high street computer stores or via you as the Reseller. Please note that BT do not offer customer support for these devices, and all technical queries must be directed to the device manufacturer or the point of purchase.
