Yahsat Satellite

Yahsat Offers A Wide Range Of Satellite Services To Meet All The Major Market Requirements:
YahClick will be provided by Y1B, Yahsats second satellite which was launched in the second half of 2011 across 24 countries in South West Asia, Africa and the Middle East. The countries under YahClicks satellite coverage are UAE, KSA, Kuwait, Qatar, Bahrain, Oman, Yemen, Jordan, Syria, Lebanon, Iraq, Turkey, Afghanistan, Pakistan, Iran, Cyprus, Nigeria, Sudan, Egypt, Kenya, Tanzania, Uganda, South Africa, and Angola.

Y1B will be the first satellite in the region to offer internet connectivity through the latest technology, the Ka-band multi-spot beams, with reusable frequencies to maximize spectrum efficiency. The multi spot-beam technology means greater efficiency on the ground, which enables use of a smaller antenna size with a low power amplifier.

How Satellite internet works

Satellite Internet is the ability to transmit and receive data from a relatively small satellite dish on Earth and communicate with an orbiting geostationary satellite 36,000 kilometers above Earth's Equator.

The satellite transmits and receives its information to a single location called the Network Operations Center or NOC (pronounced "knock"). The NOC itself is connected to the Internet (or private network), so all communication made to the Internet must all flow through the NOC.

Data communication via satellite is not much different than someone using a land based data provider. The key to remember is that once the satellite system is configured by the installer, the service acts nearly identically as any other data service and may be configured as such.

Satellite Equipment

The Satellite Modem
This is a small modem much like any land based modem that is connected to the end user's computer and the satellite dish.

Satellite dish
Yahsat mini-dish (74cm & 98cm) receives signals from the satellite, and sends signals from the customer up to the satellite. This small dish can be mounted on a roof, wall or via pole mount in the ground.

Outdoor Unit-The Radio
Besides the dish (also called the reflector) what makes up a satellite system is the BUC (pronounced "buck") which is simply the transmitter, and the LNB receiver. Both require a high performance coax cable connected to the indoor Satellite router. BUCs come in different wattages. The higher the wattage, the greater the satellite system can perform in both speed and in poor environmental conditions. Consumer systems normally use a 1 watt BUC. Business systems use a 2 watt BUC with most systems.

The main advantages over conventional satellites include:

More efficiency on the ground which enables use of a smaller antenna size (75 cm)
with low power amplifier driving down the cost of user equipment.

Cost effective bandwidth supply due to efficient frequency re-use in spot beams.

Faster access speeds with high reliability (Terminal supports data-rates of more than 15 Mbps on the downstream and 3 Mbps on the upstream)

Key YahClick Characteristics

  • High speed shared broadband internet connection
  • Direct from satellite to gateway to user
  • Affordable
  • Reliable
  • High performance
  • Last mile solution
  • Shared network, all users reside in a single large pool within a beam

YahClick Strengths compared with Ku/C band VSATs

  • Highly optimised, large scale gateways managing the traffic, maximise performance. Wide user pool reduces congestion.
  • Real broadband offerings ranging up to 15Mbps
  • Affordable Bandwidth, with very competitive monthly subscriptions
  • Small 74cm antenna, lower cost, simpler installation time and cost, little site work needed
  • Signal routed directly to/from customer to satellite to backbone at the YahClick gateway. No in-country last mile hassles.
  • Powerful small beam ensures strong signal quality. Users grouped geographically in one small spot beam over 300km diameter.
