The long road from Analogue to 4G mobile

From then to now?

Many many years ago when the yuppie hoard roamed the western world there came a really useful form of communications in the form of a portable phone. Portable was the description but it was more akin to ‘luggable’ and came in the form of a small suitcase or brief case connected to a car battery or similar. At the time they were the rich business man’s toy and remained so for some time with the key advantage being that you could tell your wife that you were on the way home and to put the dinner on! How things have changed over the last 25 years!

Analogue technology was very quickly replaced by Digital at the beginning of the 90’s and GSM was born. This was a natural evolution from a specification that was developed in the Nordic countries called NMT (Nordic Mobile Telecommunications). It was such a good fit that it became the major template for the new standard although the operating frequencies necessarily had to change. Operating frequencies and their availability remains a major theme of all development discussion in this space to this day and is likely to always remain so. Incidentally, this left two major telecoms vendors in a remarkably good position to supply the world with mobile terminals and Nokia and Ericsson started to clean up with one company becoming almost preeminent for the whole of the 90’s and even into the 00’s. But, as Nokia now know, nothing can ever be taken for granted.

What grew up behind this development was a battle between Europe /Asia and the USA and Japan. The major market developed in Europe and Asia and the USA lagged behind. Japan managed to maintain a considerable growth and innovation with their standards approach but it had little to do with the rest of the world and just made it a difficult market to enter for western suppliers. This is a whole historical piece on its own but is really just an interesting subject conversation and considered opinions as to how this period became so complicated.

Things are much clearer now however, or are they? Now we are heading through the 3G period, with 2G almost forgotten, (although used by us all on a daily basis) and with many improvements being layered on top of the old standard. Now we see HSPA in its two main varieties HSDPA and HSUPA, the D and the U in both cases standing for Download and Upload. These services provide High Speed access to mobile at and around fixed broadband speeds where network is available.

We are now moving slowly towards 4G and LTE services and these are expected in the UK in 2013 if all goes to plan. Briefly, LTE stands for Long Term Evolution and is a subset of the overall 4G standard. As usual, there are standards, and there are standards; which leaves some confusion. The major hardware vendors are all rushing to get their interpretation of the ‘standard’ out there and working to prove a point and accelerate growth. Certain parts of Scandinavia, USA and Arabia are already starting to offer trial services although the terminals are not in the mass market yet.  The consideration of these standards and services requires considerable explanation but for now, let’s have a look at the quantum jump in speeds we can expect in the future if all works out perfectly – which it won’t!

What is LTE ?

What is LTE ?

To help answer the question “What is LTE ?” we have compiled the following information.  LTE (Long Term Evolution) is the project name of a new high performance air interface for cellular mobile communication systems. It is the last step toward the 4th generation (4G) of radio technologies designed to increase the capacity and speed of mobile telephone networks.  LTE is commonly known as 4G so you may have started to hear about the latest 4G phones, 4G Mobiles, 4G modems and even 4G Routers.

LTE will support typical download speeds of 100Mbps and upload speeds of 50Mbps, however the initial LTE products including LTE mobile Phones, LTE Smartphones and LTE Routers will typically support either 21Mbps or 42Mbps, but these will be subject to the availability of LTE networks.

When will LTE be available in the UK?

O2 and Huawei have just finished trials of an 4G Mobile Network LTE service in Slough where they reached download speeds of 150Mbps.  However, the UK mobile phone operators will need to move quickly to roll out 4G LTE services becuase acording to a recent Financial Times article, Hong Kong based PCCW is looking to roll out an LTE network in the UK through its UK subsidiary UK Broadband.  PCCW recently aquired all the UK WiMax licenses and plans to operate its 4G network using the 3.5GHz and 3.6GHz frequencies for LTE.

LTE Hardware

There are a growing number of 4G phones available, but with no usable network they will not live up to their performance claims in the UK and there are also a growing number of other 4G business hardware solutions such as 4G Routers.  A good example is the Vololink VA126 LTE router which can provide download speeds up to 42Mbps and is available to buy now, which is great if you live in one of the LTE network trial areas but we imagine that as LTE services are rolled out during 2011 and 2012 in the UK then products such as the Vololink and Zalip HSPA+ routers that can take advantage of the high speed LTE mobile broadband networks will become more popular and start to replace the 3G router products currently being used for IP CCTV and M2M remote monitoring and management applications.

In summary, the answer to the question “What is LTE ?” is that LTE is high speed mobile broadband offering potentially faster sdownload speeds than traditional wired broadband services for use with LTE mobile phone handsets and other mobile broadband equipment such as LTE Routers and LTE Modems.


Vololink 3G Routers now available from the 3G Router Store

The Vololink range of 3G Routers, 4G Routers and LTE Routers are now available in the UK from the 3G Router Store from Westlake Communications.


The available range initially includes the Vololink VA126, Vololink VA125 and the Vololink VA122 Embedded HSPA 3G Routers which will work with all 3G mobile broadband SIM cards from the leading networks including Vodafone, Orange, T-Mobile, Everything Everywhere, O2, 3 Mobile ( three ) and are also suitable for use with fixed IP SIM cards available from specialist network providers.

The Vololink 3G routers are ideal for a variety of applications including 3G Wireless Broadband Backup of ADSL Bradband services, remote, temporary or mobile offices, disaster recovery and M2M (Machine to Machine) applications including IP CCTV, Digital Signage and remote monitoring and management.  3G Routers are also being used as a back up for VoIP applications such as SIP Trunking and Hosted Telephony.
