What Satellite can and cannot be used for

What Satellite Broadband Can And Cannot Be Used For

ApplicationOperation via SatelliteRecommendations / Limitations
HTTP (web) browsing

 

Works very well
TV on demand such as BBC iPlayerWorks very wellNB: data allowance limitations an SD film use 0.75 GB HD film 4.5GB
Facebook, LinkedIn and other social media sitesWorks very well
FTP and TFTP applicationsWorks very well
Video on demand such as love film & NetflixWorks very wellNB: data allowance limitations an SD film uses 0.75 GB HD film 4.5GB
Internet RadioWorks very wellNB: data allowance limitations 8 hours of internet radio will use 1GB
Citrix (Thick Client)Operates but some issues are knownCitrix 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 WellA Citrix engineer should be consulted prior to its use over satellite to optimise the timeout parameters on the server.
SSL VPNWorks very wellUnfortunately SSL VPN encryption only works for Web-based applications, therefore cannot allow secure file transfers from a Data Centre or FTP sever
IPSec VPNWorks but limited to typically 150kbps or lower per TCP sessionIPSec 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 limitationsIt 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 wellNB: data allowance limitations a 5 Min Video Clip on YouTube will use 0.1GB
IMAPI e-mail (Microsoft Exchange server etc.)

 

Works with noticeable delayNewer 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 serversWorks  very well
POP3/SMTP emailWorks WellCheck 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.
VoIPWork with limitationsCustomers are welcome to use VoIP but there is no guarantee that Voice quality will be maintained throughout the call.
SkypeWork with limitationsSkype 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 ApplicationsWork with limitationsLarge 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 emulatorsWork with limitationsMust have local-echo enabled at the remote site in order to perform properly
Shared desktopTCP acceleration helps with bitmap files of screen images,
FTP & TFTPWorks very well
NetBIOS

 

Does Not functionThis 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 delayIs 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 PointsWorks very wellCustomer 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.
