Cellular Market Headlines
• LTE rolling out faster than expected
• Cheaper, faster, easier
• Better for rural with 700/800 MHz spectrum
• Global Public Safety push to use LTE
• 3G being used for cost or regulatory reasons
• Handsets still cheaper (second-hand ones) –
all new chipsets support LTE
• Some countries tie spectrum to technology
• 2G coverage for USO etc.
• Still most efficient for basic voice coverageFrank Bennett / Orionist - Data: LTE World Map and LTE Evolution Report
Why LTE for Rural?
• Wide range of low, medium & high power eNBs
• Availability of low frequency band (UHF) systems that give 4x greater
coverage than GHz options
• No annoying distance limitations on small cell versions due to
processor limitations (cf most 3G small cells)
• Consistent backhaul technology for rural, remote and mobile locations
Why LTE for Public Safety ?
• Drive for data for blue-light services
• Uplink speeds very important to return live video
etc. as well as classic downlink use-cases
• Ubiquitous coverage using low-band radios
• As obtained from existing 450MHz TETRA /
Tetrapol etc.
• Highly responsive PTT service
• Satellite will be needed to meet these requirements
iDirect SatHaul™ for LTE
• Development lab focused on 3GPP s/w support
• Dedicated team focused on cellular and satellite integration
• Advanced software features for better 4G performance
• Stronger user experience
• Improve efficiency making a better business case and ROI
• New EC series of satellite remotes for CB
• Fully featured satellite remote with embedded advanced applications
• Open Intel / Linux environment
• Supports multiple concurrent applications – upgradeable
• E.g. LTE, 2G/3G, Local switching, PTT server etc.
• Combined with the satellite modem as a ‘data-pump’
