If, for example, you'd like to see which FTTH devices support VOIP and use dual band wireless, start by selecting FTTH and take note of the supported devices. From there, click VOIP and see which of those devices remain in the list. Now click dual band wireless and although other devices might show up, you should only be taking note of the devices that previously supported the features you had selected.

Here are some helpful FAQs on the various technical terms above

Making sense of technical jargon

VOIP stands for Voice-Over-IP. This means your voice calls no longer go along your traditional copper telephone cables and can now be integrated directly with your data at reduced costs. In order to take advantage of this, you will need to be able to connect with a username and password (just like you do for your data account) to what is called a SIP account. The SIP account handles your voice calls. This requires a device that support SIP connections. Often you can purchase a specific VOIP phone which handles this SIP connection, however this is often best performed by your router itself, which is why we offer routers that support SIP.

Our Crystal Web VOIP supported routers allow you to connect your ordinary analogue phone line to the router without having to purchase new digital hardware.

If you wish to use VOIP and prefer to use a wireless handset, you require what is called a base-station, which acts as the primary wireless phone receiver, and manages all wireless handsets that are connected. Crystal Web DECT supported routers have this function built-in, meaning that all you have to do is pair the wireless handset with the router, and your VOIP calls will be handled by your wireless handsets, all managed centrally by your router. It's intelligent VOIP, done right.

Remember that you can use VOIP on your smartphone instead of a separate device and each family member can register the same credentials, so there really isn't a need for physical hardware in the home unless you prefer it that way. An ingenious use of a spare smartphone may be to load your VOIP credentials onto it and use that instead as your physical device.

If you wish to use the latest in technology and save on your phoone bill each month, VOIP is your best option. If you wish to use the a wireless telephone in your house with VOIP, you will need a basestation for that wireless phone to connect to. That's where DECT comes in.

Simply put, no. You can opt to use an app loaded on your mobile phone like Zoiper which will route all of your calls to your mobile phone, and allow you to make calls using VOIP over your mobile device.

If however you wish to connect your existing analogue phones and wireless handsets in your house, you can do so using our devices that we offer, that provide for an analogue phone port connection. This means you would simply plug your existing analogue phone into the router and connect your VOIP credentials in the router admin interface.

If you wish to connect your wireless handsets, you will need a device that supports DECT. We recommend trying out Zoiper and using your mobile phone instead. It's really easy, and it means your VOIP calls go with you everywhere that you are.

In today's modern world, broadband speeds are getting faster and faster, and houses are getting bigger and bigger. Combined with concrete walls and other wireless and electrical signal interference, the biggest bottleneck in achieving your broadband throughput can often be your home wireless setup. Crystal Web offers AirTies wireless mesh units, which seamlessly connect to each other with a single press of a button, and provide up to 1Gb/s (10x faster than 100Mb/s) wireless connectivity throughput your property.

Traditionally, wireless range extenders have been used to achieve better signal, however these only serve to create more interference and are often unreliable. A mesh network rather stitches together each device into its own part of the wireless spectrum in order to be avoid these types of problems, and all devices communicate with each other at all times to retain the highest possible speeds. No cables to run! No complex setup process. No wireless speed bottlenecks. Just plug and play to extend your home or office wireless network up to 1Gb/s.

ADSL, ADSL2+, and VDSL are all technologies that form part of the broader DSL network technology. They use copper cables to connect your house to the nearest infrastructure, and thus require different routers/modems to those used for FTTH connections, which typically use an ethernet cable to connect into your premises. Put simply, DSL technolology requires a copper telephone line to connect to the router, while FTTH doesn't.

Make sure to choose the correct device when upgrading or changing your connection.

While using our feature comparison, you may notice that some devices show features for numerous functions and technologies, such as a single device that supports ADSL, VDSL, and FTTH. This is called a multi-purpose device, and means that it will support all of the features and networking technologies that show as applicable for the device. This can save you quite a lot of money as you consider upgrading to newer technologies, such as upgrading from DSL to FTTH, or deciding to use VOIP services without having to buy new and expensive devices.

Make sure that you're buying the right device for your upgrade needs to save money.

Most people could greatly benefit from one. Wireless mesh networks are advised for large properties and high speed connections, such as VDSL and FTTH. No single WiFI device will ever cover an entire home with full speeds to all corners. To ensure that you are connecting with the best possible technology and to take advantage of your high speed broadband connection, you should invest in a simple, no fuss, plug-and-play wireless mesh network. The same principle applies to large homes even with slower speeds than VDSL and FTTH. Mesh networks for the home and office not only increase speeds, but increase reliability and wireless coverage.
