Abstract

Thes case studies illustrate the flexibility of the Romantis equipment and utilises those to create

a capex and ofex benefit compared to other satellite modem products.

IntroductioniSat is a reseller of the Universal Hardware Platform (UHP) satellite modem manufactured in

Germany by Romantis. The UHP has the ability to operate in SCPC, Full Mesh, TDM/TDMA star

hub, and economical combinations of all three. The different operating modes are features

which are enabled by the purchase of different software keys.

A unique feature of the UHP is that it has 2 receivers- a DVB reciever and a TDMA receiver- both

of which can be receiving at the same time.

The Romantis includes a VLAN capability, so IP traffic can be directed effeciently even in Full

Mesh mode, (ie when you ping a site- you dont get all the sites responding).

The Romantis has multiple levels of QOS to prioritise traffic, as well as programable TDMA slot

lengths, and minimum fixed slots per site. Together these three features mean that for voice

traffic:-

When a fixed number of slots are available for a site it can mean the voice gets loaded

into a slot without the need to request a slot from the hub and wait.

The TDMA slot length can be long (for maximum effeciency), or can be short to reduce

the time delay for voice.The packets for voice traffic can be prioritised over other forms of traffic to ensure that

voice gets on the TDMA faster than other data.

When the system is configured correctly, the result is an incredibly high control of the quality of

the system for voice, which can have lower delay (even including the satellite delay) than is

sometimes experienced with terrestrial SIP voice systems.

The Romantis is universal hardware, so even at the end of a 2 or 3 year contract- if they arent

needed any longer, they can be redeployed/ re-enabled to operate in another network.

Case Study 1. 5 site in-country network

ContextA mining company in an African country wants to connect its HQ in the capital city in country,

with 4 remote sites that has to use satellite. The in-country regional hub has a 2.4mtr, and 1.8 is

desired at remote sites to keep transport costs down. The M&C supervision and internatiional

connection is through a European based hub.

Network configuration optionsVarious options can be considered and in each case the points represent the following stations

diagramatically

Topology Positives Negatives

Remotes and Hubs can all

share one pool of bandwidth

up to maximum 6.5Mbps- inthe described case TDMA

would be about 756kbps.

Although remotes have

1.8mtr and they need a

timing signal from the

Master Mesh device, they

dont need to receive each

others signal to be timed.

The Master Mesh unit in

country or in supervisory

hub needs to rx all remotes.

Remote stations with only

1.8 mtr antennas need a high

capex BUC to be part of the756kbps bandwidth TDMA

pool.

In full mesh the maximum

modulation is limited to

QPSK, so the high bandwidth

outbound from in country

hub is ineffeciently using

satellite bandwidth.


5/13



TDM/TDMA regional hub with all other

sites in a star network.

A traditional solution with

benefit of shared outbound,

and shared inbound on the

major routes.

From the remote sites, both

international voice and

internet takes a double hop;

which means that the 256K

that is expected to be

running through the

supervisory hub is actually

consuming up to 512K.

Theres no direct connection

between M&C and remote

stations and connection is

dependent on in country

hub. If that goes down, then

all stations are unreachable.

The capex for the hub for

such a low number of sites is

large.

The in-country hub uses

highly effecient DVB-S2 to

download the 500kbps into

the remotes and supervisory

site.

The remote BUC size isreduced, as the Full Mesh

TDMA carrier is smaller.

The remotes and supervisory

hub are using both DVB-S2

and TDMA receivers.

All traffic is single hop.

The in-country hub is timed

by the Master Mesh unit

residing in the supervisory

hub so its TDMA receiver is

available to be part of the

TDMA pool.

The capex of a TDM/TDMA

hub is avoided.

Recommended Spares

Recommended spares would include a full mesh master for the hub (5,900), and one full meshslave at the in-country hub (3000). This in-country spare can fullfill the role played by any of the

UHPs at any in-country site (hub or remote). The hardware is the same at all the in-country

sites, and the UHP feature set includes all the features available at prices up to and including

the highest cost feature purchased.

Calculated BUC size

The BUC sizes on the 1.8mtr were 5 watts and calculated to be below the requirements of ITU

neighboring satellite interference.

The BUC size at the 2.4mtr regional hub was 20 watts.

The infrastructure at the supervisory site was already established.

Case Study 2. A scaleable network approach.

Context

The customer wants to start a small scaleable VSAT network, and gradually pay more for higher

technology as the savings in the incresaing volume of space segment cost justify the

investment.

Cost effective UHP SCPC DVB-S2 modems

The solution in this case is to start with transmitting from UK in TDM DVB-S2 and return SCPC to

a bank of SCPC receivers. The maximum modulation is 16APSK ACM in DVB-S2.

With growing numbers of remotes, a point will be reached when its justified to change the UKhub to a TDM outbound as before, but create a TDMA pool on return. The TDMA pool for a

small number of sites is most cost effective using the TDMA full mesh option.

With further growth of remotes, a decision can be taken to invest in a full TDM/TDMA hub

reducing the cost of remote hardware to the minimum. The following tables illustrate the 3

phases.

Hardware cost phase 2 TDM DVB-S2 outbound, Full Mesh TDMA.

The network operator recognises that creating a shared inbound TDMA channel from the

remotes would make a huge advantage of the space segment so changes the configuration to

retain the TDM outbound, and use a full mesh TDMA return channel. The UHPs are upgraded

for new functionality, and any units at hub can be re-allocated to function as remote.

Hardware cost phase 3 TDM DVB-S2/ TDMA return.

The network operator expects the network to expand to over 30 sites. The anticipated cost ofbuying so many Mesh Slaves at 3000 dollars each will create an uneconomic solution compared

to upgrading the hub to TDM/TDMA and acquiring remotes for 1000 dollars per unit.

Hardware cost phase 4 TDM DVB-S2/ TDMA return with meshed spur to

regional HQ

There is one site that needs to talk to a regional HQ. The TDMA can be controlled from the hub

to allow direct connection between remote and regional HQ. This is called half mesh and

depends on the antenna at regional HQ being adequately sized. No upgrade cost required for

this- just some bandwidth of the TDMA pool will be allocated by the hub for the function.

Recommended Spares1 unit will support any type of UHP because the supplier has sold a licence to use a product in a

certain mode, so if you despatch a failed unit, then another can be immediately enabled.

Conclusion

The two examples show that for price and flexibility, the Romantis UHP is better than any other

solution currently available in the market.
