1. Private GSM/ Mobile Network
Confidential
Proprietary of Coral Telecom Ltd

2. Private GSM/Mobile Network
Private GSM networks with full feature functionality on GSM mobiles just like any PBX extensions
Cost effective & Rapid deployment of GSM services
Backhaul connectivity: Access Agnostic; Completely integrated with legacy connectivity's like E1 / PRI / E&M / Magneto / TWT / UHF / VHF & IP
Subscriber end supports Analog extensions, VoIP devices, SIP phones, GSM phones & key phones with equal ease thereby ensuring an environment with best of all the worlds.
New Generation (Soft switch) at the core facilitates duplicated / redundant / distributed processing.
Geographically distant locations could be seamlessly connected over IP backhaul to create a private network across multiple locations of an enterprise.

3. Unique Selling Proposition
Operator’s perspective: New concept that can attract Enterprises to adopt an Operator’s GSM network which would be like a “GSM Centrex” bundled up with the Enterprises’ private PBX.
“Frequency reuse” within a macro BTS thereby making it a spectrum efficient architecture for the Operator.
Capture the captive market with Defense, Railways, Disaster Management sites, Accident relief trains, Forests, NSG commando operations & far off resorts. UHF VHF & private networks could provide the backhaul in case of a remote site.
Off shore oil rigs, Mining & drilling sites inter-connected over IP backhaul to “on shore” offices.
Franchised operations for setting up private GSM network for Group housing societies. It may facilitate quick roll out like the Group PBX scheme.
Enterprise clusters could be large focus client groups like “Loha Mandi”, “Ball bearing merchant association”, “Panchratna building with gold merchants”, etc.
Sell the concept to the Ships as a mobile communication system on “high seas” with satellite backhaul. Roaming facility at ports can be organized. SDR based BTS can auto adjust to free frequency band. This could be a large market.

4. Why Fixed Mobile Convergence ??
Cell phones are the preferred mode of communication which has the following adverse implications on cost & expenditure
Organization’s don’t get the best out of bulk rates negotiated for the PRI lines.
Free “Intra office communication” on intercoms, ends up in being a paid call.
Free Inter branch communication on dedicated leased lines ends up as paid call.
VoIP tariff plans / infrastructure if available in the company is bypassed
Standard features of PBX - call transfer / Call hold / Call consult / Conference are paid.
Enterprise wide “UMS”, IVR & Voice mail services for staff efficiency are missed out.
Call escalation process within the organization will be by-passed.
Call center services not supported on mobile phone calls.

5. “Coral Air – NGX” - IP based Fixed Mobile Communication Platform
Mobile phones fully integrated with the Enterprise PBX can reduce costs
1. Attendance recording systems.
2. Mobility voice services - Replace expensive DECT or Tetra or Cordless
telephone.
3. Call routed through the least expensive route by intelligence built into
the PBX.
4. Unanswered calls go through an escalation matrix in the company.
If an Organization is using “Coral Air – NGX” solution, then as soon as an employee walks into the area covered by this network, registered mobile phones will become an extension of the PBX in a simple, secured, automatic process without the need for any complicated password, access code or manual registration.
