There are a lot of significant issues surrounding an LTE rollout. Acquiring spectrum, developing a network map, deploying gear, testing/validation, selecting devices, building a subscriber offer… the list goes on.
When it comes to accelerating an LTE rollout, VoLGA
1- VoLGA supports SMS over LTE for data-only deployments.
The lack of native SMS over LTE support is a show-stopper for LTE dongle service. Mobile operators rely on SMS for back office customer care, provisioning and management of HSPA-dongle services. Some operators have suggested there are upwards of 50 different systems used in today’s HSPA services. Clearly those systems need to be available to an LTE-based dongle/datacard/netbook service at launch.
Upgrade your MSCs with a new interface for CS Fallback simply to deliver SMS over LTE? That’s costly, painful and very time consuming to support a service some operators will have available in early 2011.
Install an IMS infrastructure to support SMS over LTE… probably not.
VoLGA is the only alternative that can deliver SMS over LTE at a price point and timeframe that is viable.
2- VoLGA resolves the voice dilemma
While operators can initially roll LTE for data-only applications, massive nation-wide deployments come when there are mainstream LTE handsets. LTE will stay an ‘island’ technology if it’s only deployed for dongles and datacards.
The LTE ecosystem, infrastructure and device vendors, all benefit if LTE becomes the mainstream radio access network (RAN). Operators benefit too. LTE is significantly more efficient that previous technologies, and delivers dramatically lower cost per bit. Thus operator and vendor actions are aligned: drive LTE to become the RAN of choice.
But handset vendors won’t build phones until they understand the voice implications. Waiting for IMS, while a long term strategy, will only serve to delay handsets and thus leave LTE in a data-only state.
An immediate solution is needed to support voice from the existing network infrastructure. Between VoLGA and CS Fallback, the choice is crystal clear. CS Fallback just falls short. It delivers a sub-par user experience, it requires costly and painful MSC upgrades, and it doesn’t support LTE femtocells at all.
Plus, if you invested in VoLGA
If the industry wants mainstream LTE services, voice is required, and VoLGA
3- VoLGA: The path to IMS
For many operators, the long term goal is IMS. Yet there is a need to make a near term decision between VoLGA
You guessed it: VoLGA
An operator eying IMS down the road wants to do two things: First, they want to get started with IMS for new revenue generating data services, like the RCS (Rich Communications Suite). Operators can begin the road to IMS by deploying the data-only components of an IMS infrastructure and deliver combinational voice/data services.
Second, operators moving to IMS want to minimize investments in the existing MSC voice network. Long term, the vision is that this network will be capped and new capacity will be added with IMS telephony. VoLGA
There are a lot of elements which go into an LTE deployment, but it’s clear that VoLGA
