Your computer and the Yahclick modem.
You may connect your computer directly to the Yahclick modem with an Ethernet cable (included). Better yet, connect a wireless router to create your own local wireless network, enabling you to connect multiple computers, tablets, smart phones and other wireless devices to your Yahclick service.
The Yahclick dish.
Our dish receives signals from and transmits signals to the satellite. It’s about the same size as satellite TV dishes, and can be mounted to the outside of your house, on the roof, or on a pole on your property.
Located in geostationary orbit, our satellites provide an efficient, effective method to provide high speed Internet service to Yemen using spot beam technology. The main purpose of the satellite is to relay signals from your home to our gateways, and back again.
Our gateways are located in different parts of the world. The gateway receives the signal from the satellite and connects it to the Internet, and transmits the data from the Internet back up to the satellite.
Everything on the Internet that’s available via a wired connection is also available through Yahclick satellite Internet service. You will now be able to browse the web super-fast, download music and movies, share photos and video chat with friends and family, and much, much more.

YahClick is a high-speed always-on Internet access service delivered via Satellite by TeleYemen.
The service is ideal for any consumer, business, or enterprise requiring an affordable high-speed always-on internet access service - especially where other alternatives:
- Are not available.
- Too expensive.
- Too slow.
- Have long install lead-times.
YahClick gets you online instantly to surf the web, watch videos, download mail, etc. Yahclick is available on a range of service plans with speeds up to 15Mbps.
The service does not depend on terrestrial cabling. Which means no long lead times waiting for cables to be installed or for cut or stolen cables to be replaced.
It also does not rely on 3G/LTE coverage.
Yahclick is available nearly throughout Yemen, even in remote areas far from cities or towns.
VSAT terminals are installed at customers’ sites by authorized installers. Each terminal consists of a small dish installed outside at a carefully selected position to ensure it has a ‘clean’ path between the dish and the satellite. The dish connects via coaxial cable to the satellite modem installed indoors, delivering internet access via its Ethernet port(s).
The satellite ‘relays’ signals in the Ka frequency band, between the VSAT terminal and an earth-station in Athens or Abu Dhabi, ‘connecting’ the VSAT terminal to the internet.
The service is available almost throughout Yemen. Coverage is delivered via 2 high-power spot-beams, each focused on a specific part of the country, overlapping in some areas.
The further a customer is located away from the center 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 3 dish sizes being deployed for this service are: 74cm (oval), 98cm (round) and 120cm (round).
There are numerous packages that can be selected 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 50% 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 Athens or Abu Dhabi, 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 Yemenn service is almost 800ms (round trip).
There are many speed test services available on the Internet. As only a small % of global internet users connect via satellite networks, 99.9% of these speed test services are tuned for terrestrial wired services such as ADSL - but give incorrect results when testing via a satellite based service. The test methodologies used by these services are not 'compatible' with the tcp acceleration features built into all modern satellite based networks.
For an accurate speed test, we have our own system that we know delivers accurate results. We can be sure of the speed test results when we deliver a file from "our side" of the customers' internet connection. This gives a true and accurate reading of the access network performance between the customer and our gateway at the satellite earth-station in Europe.
Once the 'traffic' enters the European Internet back-bone, there are many factors beyond our control which can affect the speeds.
The Yahclick service comes with a facility for testing download and uploads speeds. You can access this facility via the Yahclick end user portal - (https://eupgateway.yahclickonline.com)
If you insist on using speedtest.net, first change your ‘Preferred Server’ to ‘Athens or Abu Dhabi – DATACENTER (depending on your location) to test the performance of your Yahclick satellite link. If you do not, by default the test will be run against servers in Yemen delivering wrong results.
Yahclick is a great service, but it’s not for everybody.
For some activities and use-cases, Yahclick may not be a good match.
- Own tunnel based VPNs. Tunnel based VPNs do not work well over satellite links. You can implement VPNs over YahClick plans using L2TP, PPTP, IPSEC and other tunnel technologies, but you will experience reduced speeds by as much as 50-75%. Satellite platforms cannot accelerate connections running through tunnels. Should you choose to run tunnels over your satellite connections, you forfeit the benefit of many acceleration features built into the platform designed to compensate for high satellite latencies. TeleYemen does not provide help with configuring or troubleshooting problems associated with such tunnels and their VPN clients.
- Twitch Games. Time-sensitive applications that require fractions-of-a-second user inputs (such as multi-player "twitch" games or real-time equities trading) are not recommended with YahClick due to latency issues. 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 up to the satellite and back (about 72000km). This round trip adds about a 600ms delay to the total time your computer takes to communicate with a Website or host server.
- Many Concurrent Voice Calls. To ensure voice quality, a network connection must support a feature called ‘Quality Of Service (QoS)’ that prioritizes voice traffic over normal data traffic (e.g. http, Youtube, torrents, etc.). Without this prioritization, the audio clarity of a voice call will deteriorate from time to time due to other traffic on the network. Activities such as opening a website, watching a youtube video, or downloading a file, will cause audio interruptions. The service plans available each have a limit to the maximum number of G.729 concurrent calls supported with QoS. If you need to run more concurrent calls that what is supported in the available service plans, or if your system does not support G.729, you will experience intermittent or persistent call quality issues.
- FoIP. Yahclick does not support running Fax over IP calls.
- FTP active mode. Yahclick customer terminals connect to the internet via a core firewall that performs dynamic Network Address Port Translation (NAPT). When using any ftp client located behind a firewall, you must configure your ftp client to use ‘passive’ mode and of course the ftp server you are connecting to, must also support passive mode connections. Nearly all ftp clients these days support passive mode connections. Before signing up for the Yahclick service, please ensure that any of your applications leveraging ftp can indeed be configured to run in ‘passive’ mode. If your application for some reason only supports ‘active’ ftp connections, then you can not use that application over a Yahclick connection.
- No direct line of sight to satellite. A mandatory requirement for using YahClick is that you must have a clean line of sight path between the installation location and the satellite. There should not be any vegetation, trees, buildings or any moving objects such as vehicles or people obscuring the direct line of sight path.
- Latency Sensitive Applications. Some applications just do not work well when being used over high-latency satellite links. Some may not work at all due to too-short timeouts hard-coded into the software. Before signing up for YahClick, please verify to ensure that your applications work via satellite links.
To ensure that all YahClick High-Speed Internet Service customers have equitable access to the network, YahClick sets usage allowances on the amount of data a subscriber can download within stated time periods specified in each service plan. If at any time a subscriber’s Usage Total is above the Usage Allowance, the YahClick system will temporarily limit the speed at which the subscriber can receive data over the network. Subscribers will still be able to use the Internet service but at a lower speed. The YahClick Fair Access Policy “FAP” is designed to impact the fewest customers who overuse the network while helping ensure the highest speeds for the vast majority of the users. In most networks, 5% of subscribers use 50% of the traffic. FAP policies are implemented by all to prevent abusive consumption of bandwidth by a minority of users.
The best way to describe usage w.r.t FAP is using the ‘bucket’ analogy as depicted below.
‘water/data’ runs into the bucket at a constant rate of ‘A’ liters per hour = (0.1 X Monthly FAP Allowance) / 72.
For example, on a service plan with a monthly allowance of 15GB per month, the bucket is filled up at a rate of (0.1 * 15000) / 72,= 1500 / 72 = 20.833 MBytes per hour.
When ‘water/data’ is consumed, they flow out of the bucket at rate B (Mbytes consumptions per hour).
So if you are emptying the bucket faster than the rate at which its being ‘filled’, then you will eventually have no more water/data left in the bucket and you will go into FAP. As you go into FAP, the size of the valve opening at B is reduced significantly, so as to ensure that the ‘water/data’ running out of the bucket can never exceed the rate at which ‘water/data’ is running into the bucket.
Once the bucket reaches a level of 33% (24 hours with zero usage) the valve will be fully open so that the maximum data can be used. But when you are in FAP and you still keep on using the data which is flowing into the bucket, you may never go out of FAP because the bucket only fills up at the rate of A.
When the bucket is full the data will still be flowing at a rate of A but it will overflow and the data usage will be lost.
By managing your daytime downloads your can maintain your enjoyment of high speed internet without experiencing any speed downgrades. Please note that YahClick also offers unlimited uploading so any photos or large files uploaded to the internet will not be counted as part of the data allowance.
When you apply a FAP token the bucket will get filled up, so you can use as normal and thereafter the bucket gets filled up at a rate of A and the B is still equal to the actual usage.
Note: This concept is applied only on the old packages. New packages outlined under Products are not having this policy.
The ‘Free Zone’ starts at 1:00am and ends at 6:00am. During this time, customers can enjoy downloading data at full speed without it counting against the Download Allowance.
This period has been provided for YahClick subscribers to schedule the downloading of automated updates or to download other large files. Its an incentive for users to rather schedule the downloading of large files to occur when the network is less busy and not place unnecessary load on the network during peak usage hours.
Download speeds are not guaranteed during these hours and this period is subject to available satellite capacity. Yahsat have reserved the right to review the availability of the FreeZone, or apply charges if there is network abuse during this time.
We recommend that you schedule your automatic system updates to occur during the FreeZone. Use a download manager software application to automatically schedule large file downloads to occur during the FreeZone.
Yes, you can connect multiple computers and laptops to a single YahClick Internet connection. Home networking equipment may be required and is not included with your YahClick system.
For network setup, support, and configuration, contact your network hardware manufacturer and/or operating system software developer (TeleYemen is not responsible for home network configuration or management).
Please understand that all computers on this network will be sharing a single connection. Simultaneous use of high-bandwidth applications by multiple users may result in degradation of speed and is subject to the YahClick Fair Access Policy.
Consumer service plans come with modem equipment that is designed for home users. In an average home there will be 1 to 3 computers served by the Yahclick terminal.
In a business environment, where there could be 20 simultaneous PCs served by a single modem, each operating a large number of user sessions, the business grade terminal is more powerful to handle this load. The business terminal also has two LAN ports.
14.Can YahClick’s NAPT firewall be configured so I am able to connect from the Internet to multiple devices/servers installed behind a YahClick link?
The Yahclick NAPT firewall simply does a one-to-one NAT and does not take port ranges into consideration at all.
To accomplish this, you need to install your own Firewall behind your YahClick terminal, accessible via a Static Public IP (an add-on available on the Business Service Plans) and do your port-based NAT translations there.
No, you cannot turn off the DHCP server or change the IP or the IP range of the modem. The only way to get around this is to put a router between the YahClick modem and your network.
The satellite router’s LAN interface is configured with a /28 network. This subnet is automatically allocated at the time of provisioning the terminal. It is not possible to specify or determine what this subnet will be prior to terminal provisioning.
When not deploying an additional firewall behind the Yahclick router, the maximum number of user devices that can be supported directly of the LAN interface is limited to 13.
Customers with more devices on their LAN, will need to install their own router/firewall with its WAN interface plugged into the Yahclick modem’s LAN interface.
YahClick 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 analyze 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
The YahClick system requires a unique dish in order to send and receive information via satellite. You cannot use your DSTV dish for YahClick high-speed Internet service.
Yes, provided you apply for a static IP
There is however an additional cost for a static IP on consumer service plans.
To ensure voice quality, a network connection must support a feature called ‘Quality Of Service (QoS)’ that prioritizes voice traffic over normal data traffic (e.g. http, YouTube, torrents, etc.).
Without this prioritization, the audio clarity of a voice call will deteriorate from time to time due to other traffic on the network. Activities such as opening a website, a YouTube video, or downloading a file, will cause audio interruptions with duration lasting from fractions of a second, to minutes.
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 prioritize voice and supports between one and eight concurrent G.729 encoded voice calls – depending on the service plan selected.
If your system negotiates G.711 on any call, your voice traffic exceeds the amount available on your service plan and quality will suffer.
For the QoS to work correctly, you VoIP system must be configured as follows:
- a) Codec: G.729 (Products that only support G.711 can not be used)
- b) p-time: 40ms (highest priority) followed by 20ms (second priority).
- c) Must run your SIP trunk to TeleYemen’ network.
- d) Use "yc.vphone.co.za : 5070" as registrar / sip-proxy.
- e) Do NOT enable STUN.
Please note that users who do not subscribe to a ‘Voice’ enabled service plan, will still be able to run voice over their YahClick links – however the quality will vary between good and very poor (especially when concurrently downloading or uploading large files).
Take note that should you exceed the maximum number of concurrent calls provided for by your service plan, all the voice calls (including the first one placed) will experience quality problems.
Please note that Yahclick terminals accesses “yc.vphone.co.za” via dedicated leased capacity – not via the Internet. It is therefore not possible to reach yc.vphone.co.za via other Internet access services. SIP devices ‘talking’ to yc.vphone.co.za that have STUN enabled, will experience problems such as the inability to receive inbound calls, or one-way audio.
A G729 call will consume 22Mb/hour
The voice packages only support G729 with a p-time of 40ms as highest priority, followed by a p-time of 20ms.
During periods of bad weather, the link can go down for short intervals because of signal attenuation caused by rain. The system automatically compensates for such signal attenuation, boosting its power levels to compensate - up to a certain point.
Heavy rain, hail or snow occurring overhead customer terminals, or the earth station in Luxembourg, will cause signal attenuation and could result in short services outages.
YahClick service terminals are not Wi Fi enabled. However, customers may connect their own wireless devices to enable Wi Fi. However, TeleYemen is not responsible for troubleshooting wireless routers or other devices that were not sold as part of the Yahclick solution.
26.If I order a Yahclick Static Public IP Address, is it routed down to the LAN side of the YahClick modem?
The Static IP Address is configured as a one-to-one NAT on a centralized NAT Gateway router.
If you ordered a Static IP Address, then at least one of the devices on your LAN will be accessible from the Internet, using the assigned Static IP Address. The remaining devices will not be accessible from the Internet.
Even though these remaining devices are not accessible from the Internet, they are still accessible from all other Yahclick terminals on the Yahsat network by connecting directly to their statically assigned Private IP Addresses. For security reasons – you must keep this in mind and keep your devices secure. Install a firewall between your LAN devices and the satellite modem.
There is a “Choose your connection speed to optimize performance on the Experience tab under Options” in Remote Desktop Connection. When connecting to the remote computer, set the connection speed to Satellite (2Mbps – 16 Mbps with high latency).
If you forget to use this setting, you may find your connection randomly dropping, or you are not able to establish the connection at all.
To connect from the internet to a PC installed behind a YahClick link using Remote Desktop, you will need to connect to a Static IP which NATs through to that PC. So you will need to order a Static IP.
However keep in mind that downloading can consume a lot of your bandwidth and will also eat into your FAP allocation. It is also likely to slow down other activities such as normal browsing. We recommend that you schedule your downloading to occur during the “Free-Zone” between 1AM and 6AM.
When you connect to the Internet using YahClick, the upload and download speeds you experience will vary based on a variety of factors including the configuration of your computer, the number of concurrent users, network or Internet congestion, the size of the websites you are accessing, and many other factors.
Yahclick does not deliver a dedicated unshared pipe for each customer to the internet. Just like ADSL, the speeds indicated on Yahclick packages are the maximum "Up-To" speeds. During periods of very heavy concurrent customer demand, the speed experienced by a specific customer will decrease. Speeds may also be affected if there is a major event and all users are trying to access the same content at the same time.
Yahsat's capacity planning rules are such that the average speeds customers experience during the busy hours should not fall below 50% of the up-to speed. But still, this is no guarantee that it never will.
What about the satellite latency? The satellite technology used compensates for the high satellite latency between the customer terminal and the earth station, so it does not hamper TCP throughput.
Customers need to take into account that Yahclick is delivered via an Earth-Station located in Europe. So its just as if the customer happens to be located in Europe.
32.My download allowance status meter does not seem to match my usage reported on the Check Usage page. Why?
The Download Allowance status, available through the YahClick Status Meter application or via your terminal’s System Control Center, reflects the actual number of bytes you can download before your download speeds are reduced. This status comes from the YahClick gateway in real time as you receive data. The Check Usage page displays the total historical data downloaded and uploaded from your terminal. This data comes from usage records that are updated hourly. Based on network policies and system status, some data transmitted to your terminal may not be counted against your Download Allowance, but all data will be recorded on the Check Usage site for reference. For example, any data that you downloaded during the Download FreeZone will be reflected on the Check Usage page.
Should you Upgrade or Downgrade your service plan, there is a good chance that your terminal will be allocated a new IP address range. This is especially important for customers subscribing to the static public IP feature, as the one-to-one NAT configuration would then have to be updated to reflect the new IP address.
