Connecting all of South Africa

It is a high-speed, Always-On Internet access service delivered via Satellite by Vox Telecom.

The service is ideal for any consumer, business or enterprise requiring an affordable high-speed Internet access service – especially where other alternatives aren’t available.

Satellite internet beams data from homes and business premises up into space. A satellite then receives the communication and relays it back to Earth, from where it can be sent to its intended recipient. The service does not depend on terrestrial cabling, which means no long lead times waiting for cables to be installed, or for stolen cables to be replaced.

Satellite uses sophisticated acceleration techniques to enable high-speed performance over high-latency satellite links. Without this feature, TCP connections would only deliver a throughput of around 100Kbps – simply because of the round trip latencies involved over satellite connections.

These acceleration technologies cannot accelerate traffic running inside tunnels. Tunnel payloads are commonly encrypted in any event, making it impossible to analyse the packet payload to attempt acceleration.

When running VPN tunnels over YahClick, customers need to implement their own TCP acceleration system. Otherwise the performance will be limited to around 100Kbps – regardless of service plan being used.

To ensure voice quality, a network connection must support a feature called ‘Quality Of Service (QoS)’ that prioritises voice traffic over normal data traffic (e.g. http, YouTube, torrents, etc.).

If you need to run telephone calls, please ensure that you choose one of the YahClick ‘Voice’ enabled service plans.

These are specifically designed to prioritise voice and supports between one to eight concurrent G.729 encoded voice calls – depending on the service plan selected.

The service is available throughout South Africa. Coverage is delivered via 128 high-power spot-beams, each focused on a specific part of the country, overlapping in some areas.

There are numerous packages that can be selected from. The advertised speeds are maximum “burstable” throughputs.

There are numerous packages available to choose from. The advertised speeds are maximum “burstable” throughputs. YahSat’s network capacity planning aims to ensure that during the busiest hours of usage, the throughput over the satellite path does not drop below 30% of the link’s maximum speed.

Latency refers to the amount of time it takes a packet of data to travel across a network. With satellite service, that data must travel via to the satellite (about 72000 km), terminate in Europe, breakout to the Internet and on to its destination.

This round trip adds about a 600ms delay to the total time your computer takes to communicate with an international Website or host server. The latency to a South African service is almost 800ms (round trip).

The further a customer is located away from the centre of the spot-beam (where signals are the strongest), the weaker the signals become. For sites towards the edges of the beams, we compensate for the ‘weaker’ signal by using a larger dish. The 2 dish sizes being deployed for this service are: 74cm (oval) and 98cm (round) and this is dependent on feasibility.

Fair Use Policy (FUP) will be implemented on unlimited service plans according to the soft cap limits. Should utilization reach a percentage of the allowed bandwidth threshold, the speed will be limited to a percentage of the contracted speed. This methodology can be implemented in more than one step:

• Unlimited 5Mbps: Will be throttled to 1Mbps/1Mbps after a 100GB used, 512kbps/512kbps after 200GB used during the monthly data cycle.
• Unlimited 10Mbps: Will be throttled to 2.5Mbps/2.5Mbps after a 200GB used,1Mbps/1Mbps after 300GB used during the monthly data cycle.
• Unlimited 20Mbps: Will be throttled to 5Mbps/3Mbps after a 200GB used, 2Mbps/2Mbps after 300GB used during the monthly data cycle.
• Unlimited 30Mbps: Will be throttled to 10Mbps/5Mbps after a 200GB used, 4Mbps/4Mbps after 300GB used during the monthly data cycle.
• Unlimited 50Mbps: Will be throttled to 15Mbps/5Mbps after a 200GB used, 5Mbps/5Mbps after 300GB used during the monthly data cycle.
