The bill proposes installation of femtocells and WiFi hotspots in about 9,000 buildings owned and operated by the US GSA, and to be mandatory in any future federal structures. The bill also asks for a $15 million budget for the performance of retrofitting and future installs.Click for details hereThe influence of industries and businesses over governance bodies is not new to the US.

If Femtocells were to operate on a frequency that is shared with the macro network in a restricted mode (i.e. only specific users can access a particular Femtocell), there is a concern that interference between the two layers may create a doomsday scenario. For some reason, many think that the uplink interference from Femto users will jam the macro recievers and cause macro uplink coverage to

Mobile access has become a neccessity not a luxury. Mobile operators are morphing and changing into utility-like companies, unfortunately this does not go hand-in-hand with the way mobile technology is evolving. Operators are not even close to tapping into the vast capabilities and strengths of their existing technologies and yet they talk about evolving and changing their infrastructure. It's

It's bizarre that some are talking about a 16 call femtocell. The whole idea of a femtocell is that it's a compact consumer device that provides adequate coverage and capacity within the home or place of work. Having a 16 call femtocell at home or in a shop is like driving your own bus to work everyday. It will get you to work, inefficiently, painfully and probably late... My view is that what is

I have spent some time now looking at various femtocell business cases and find it very interesting how creative some of the operators are when it comes to using femtocells to generate new revenue streams.It occured to me that sometimes it's the straightforward and simple things that get over looked in these business cases, and I wanted to go back to basics and look at the simplest scenario of

The mobile telecomm industry has evolved from few simple be-spoke systems to highly complicated and convoluted solutions that require an army of experts to anlayse and understand. With the myriad of technologies available, there are many nice innovative ideas out there. Technologically innovative ideas can be exciting and have a hypnotic effect on all of us technologist. However, very few ideas

Etisalat is the first operator in the Middle East who shows interest in FemtoCells, and therefore they asked us at Ubiquisys to showcase their femtocell on the Etisalat stand at Gitex 2008. They branded the product “Etisalat Home Cell”. So we took few units and demonstrated the first commercial femtocell ever in the Middle East and I ended up spending a week in Dubai during the Gitex technology

Link to Telecom.comInteresting analysis, though it's coming from a market demand point of view. This expectation is contingent on availability of commcercially viable femtoceels, in terms of pricing as well as technology stability. Both aspects are perfectly achievable, but the question is who will achieve them first.

The compelling selling points of femtocells are increasingly becoming more noticeable.The apparent strong compelling factor is the disruptive value proposition in terms of cost of delivering a minute of calls (or Mbytes of data) to the end user. Another obvious one is related to service bundling and other innovative marketing ideas.One area that is increasingly getting attention is the femtocell

The three points talked about in every Femtocell customer meeting:1 - Price and potential savings2 - The indoor coverage advantage3 - Architecture and how to integrate with existing network infrastructureThe Femtocell marketing effort can benefit from addressing three other areas:1- Targeting new breed of customers: Most of the effort is spent towards soliciting the traditional operators (VF, FT/

So why is Google interested in Femto cells?One view is that Google may be the first new breed of mobile operators. For a green field entrant the prospects of building a distributed network using Femto Cell technology surely has some benefit: the network is operational the minute the first Femto box is plugged in the wall and no valuable time is wasted acquiring sites, radio planning and

Here is a link to an article on BBC Technology News with a good summary of the case for Femtocells from a user's and operator's points of view.

The recent news of Google's $25 million investment in Ubiquisys is the beggining of a major change in the race to win the Femtocell race.While architecture, coverage and RF performance are some of the important areas to keep a close eye on, content and applications will be the major differentiating aspects. I talked in a previous post about content personalisation and customisation

One of the tooted selling points of FemtoCells is the enhanced user experience indoors. There is no doubt that in terms of radio coverage the FemtoCell will enable a more uniform and better RF signal indoors.The story does not end there however. The underlying concept of "convergence" with FemtoCells will give content personalisation and customisation a whole new dimension. In addition to simple

Telecoms.com (Informa's telecomm business intelligence reporting outlet) has some interesting and insightful coverage of the Femto Forum meeting that took place in London on first week of July.The article quotes Will Franks, CTO of Ubiquisys, as well as Dr. Simon Saunders, the newly appointed Chairman of the Femto Forum on the importance of bringing the femto vendors together and collaborate to

This has been out for a while, I don't know why I kept delaying linking to it:ABI research has ranked the various femtocell vendors. Check the news release here.Their ranking criteria is based on two aspects: Implemention and Innovation. This ranking is by no means a ranking of the femtocell prodcuts only. It also takes into account the overall position of the relavent company/division in terms

Reuters made a short report on a femtocell demo organised by ip.access. Check it out here. (Thanks to Mr. Adnan Boustany from PicoChip for sending the link).What I like the most about ip.access's approach is that they realised the importance of effective marketing to win customer confidence.

There are as many companies active on the femtocell backhaul integration with IP core as there are Femto cell manufacturers, with Kineto, Sonus and Tatara systems topping the list. Sonus has recently announced partnerships with three femtocell manufacturers: ip.access, 3way and RadioFrame.My worry is that some companies in the IP core space are re-inventing the wheel so to speak which threatens

Cellular News published an interesting short article suggesting that femtocell shipments will reach 36million in 2012, which in my view a rather conservative estimate. The estimate is contingent on a couple of big operators tidying up their messy business models. If operators grasp the big potential offered by the femto concept, then one can easily predict an estimate closer to 100 million plus.

In a previous post I talked about the potential benefits of femtocells to the operators as well as consumers. In this post I'd like to investigate the potential hurdles in the road to viable femtocell solutions.Looking at various analysts remarks I narrowed the list of potential show stoppers to the following items, all of which are not unresolvable, but one has to be aware of:Cost: This is the

The business case for indoor femto cells has gained increasing traction in the last few weeks, and lots of news comments about various femto cell development companies. For example, check here, here and here.Although the femto cell concept is quickly gaining grounds towards complete and operational products, there is still some misunderstanding on how the overall network architecture will look

The list of top 20 selling handsets with contracts from Mobile Today shows the weakest performance of Motorola handsets this year.In the top 20 there are: 7 SonyEricsson, 6 Nokia, 4 Samsung, 2 LG and only one Motorola made handset. The only Motorola handset in the list is the KRZR, ranking 14.I'm not sure if analysts use this kind of market trends at all when they make investment decisions, but

So Carl Icahn failed to get a seat on Motorola board. Few months back Icahn raised some valid and very real concerns as an important shareholder of the company, which any sensible corporate interested in adding value to its shareholder should keenly take on board (almost literally!) and address sincerely and with an open mind.I just could not believe how Ed Zander reacted to Icahn’s concerns: he

Both Epen and Martin made valuable comments on my last posting, so I thought that expanding some of the ideas is in place.From the consumer point of view, reduced call prices are definitely an important aspect of Femto cells. As for the interference aspect, whether Femto cells will cause more or less interference to Macro cells is debatable. On one hand the signal will be contained within indoors

Home base station solutions, also called Femto cells have recently attracted a lot of attention. The idea is to give the mobile user a small box similar to wireless routers, which provides mobile cellular coverage at home. But why would mobile operators want to do that?In order to answer this question, one has to look at what mobile operators are competing against. Fixed line carriers and DSL

MIMO stands for “Multiple Input Multiple Output”. A MIMO system consists of multiple antennas at both the transmitter and the receiver.A scattering channel can be problematic because it causes interference and hence sub-optimal reception. Many methods have been introduced to counter the effect of interference, such as interference cancellation, phased array antennas and many of the diversity

In a conventional WCDMA system, each user is detected non-cooperatively where other users’ signals are treated as noise. This basic scheme has a low implementation complexity but a limited overall spectral efficiency due to multiple-access interference (MAI).Higher spectral efficiency can be achieved by reducing the MAI. In contrast to conventional RAKE receivers, the Multi-user detection (MUD)

3GPP is constantly thinking of ways to improve the performance of UMTS to compete with new emerging technologies that promise enhanced performance over legacy systems.There are two evolution philosophies within 3GPP. One philosophy is start from scratch and design a new system with new architecture and air interface which do not have any legacy constraints. Another philosophy is to fine-tune

Steered beams are essentially the combination of two technologies: Beam-forming and beam steering.Beam-forming is achieved by using phased array antennas to create a narrow beam directed at each mobile in the downlink. The antenna elements form a phased array antenna that have very small spacing (usually half a wavelength). By virtue of the small spacing, transmitted signals from the array

At the end of 2005, the number of global subscribers exceeded the 2 billion mark. Vendors were preparing themselves for the challenge of adding the next billion subscribers.

This post is a try to summarise and distill a theme from the previous posts about VoIP over UMTS, without getting much into the technical detail, but rather by proposing a view of the telecomm market and motivations for VoIP.First, let us get the definitions out of the way:VoIP over cellular:Carry the voice conversations of mobile users using VoIP by routing them over a packet-switched network,

Just read this article by Ian Poole in IET Communications, which is a good overview of IMS architecture. (I don't know why I pay them subscription fees for the magazine when you can download all the articles for free!).I am not convinced that the need for IMS stems from the desire to "converge". The main objective for IMS is to give the operators a mechanism by which they can charge for any user

It does sound like an outrageous question, doesn't it? Everybody knows VoIP is all about "cheap"... or is it?Cellular operators who want to introduce VoIP are in two categories. Some do not have a choice, because VoIP is about the only method to carry voice traffic. Verizon Wireless with their EV-DO network is one example. Other operators see the shift towards VoIP as an inevitable mechanism to

Cellular operators seem to be confused about VoIP. On one hand they seem to think that the whole world is going IP, hence VoIP is inevitable. On the other hand, they do not want to undermine their number one profitable application: trunked voice. There is also confusion about benefits of carrying VoIP on cellular radio access networks.Most cellular operators see VoIP as a dangerous proposition

I have received some queries about the delay encountered by VoIP calls. Thanks for the interaction and questions, keep them coming.In this post I will summarise the various reasons that cause delay of VoIP speech over a UMTS network, or over any network for that matter.I should mention here that I am not trying to show that VoIP over UMTS is any better or worse than conventional UMTS (I will only

In the first episode we discussed how the various implementation options compare in terms of performance and complexity. We say that there are various necessary changes to the high speed channels to make them an attractive medium to carry VoIP traffic. Some of these changes are also necessary to reach VoIP capacities that exceed conventional circuit switched capacity. In this post I will discuss

Looking at the viewing stats, the VoIP postings seem to have stirred some interest out there.Hopefully you will find this posting equally interesting. In this one I will discuss some of improvements required for UMTS in order to carry VoIP traffic or to improve its performance.RoHC (Robust Header Compression) The various headers required to transmit VoIP packets typically add around 200-300% more

In my previous post, I looked at some of the reasons why mobile operators think they need VoIP/UMTS. In this post I'd like to investigate these reasons a bit further. The list is not comprehensive so if you think of any other motivations please let me know:Operators think that VoIP can help them utilise their transmission network more efficiently. The idea here is simple: if all traffic is IP

There has been talk in the market about introducing VoIP over UMTS networks. In this posting I investigate the viability of various VoIP over UMTS solutions. The three options presented here are: VoIP gateway, end-to-end VoIP over shared channels and end-to-end VoIP over dedicated channels.Clarification of terms:Before starting, let me clarify the term "VoIP over UMTS". I chose it because the

If you have been in the wireless business long enough, you must have noticed all the puff and hype that comes about every time a new technology is talked about. I've seen it with Edge, UMTS and HSDPA. Every time, operators are duped into believing that they will achieve unprecedented throughputs and enormous coverage. This has happened again with WiMax. What makes it worse this time is that Intel

Between the recent impounding of 50,000 handsets in Russia, and the imminent patent violation lawsuit, it is obvious that Motorola's future in Russia is in jeopardy.Read this and thisA global corporate, like Motorola, sending $100m worth of handsets without proper conformance testing is a ridiculously stupid thing to do. On one hand, Motorola keeps highlighting the importance of the emerging

In my line of work I tend to read many document, comment on them and then summarise them or take extracts from them.In the past, I used to print out the documents, scribble my thoughts and comments in the margin, and add plenty of arrows and circles. I'm awful at keeping my workspace tidy, so there are many documents scattered around me, so I tend to spend hours trying to locate the right

Telecomm equipment vendors are running around clueless like headless chicken. They jump on the bandwagon of any new technology and let cob webs grow on their long term plans, so called "visionary strategies". Here's how the thinking goes:"ok, so we think that it's time to develop a new standard, let's call it UMTS. Go and develop it, what are you waiting for?. Ok, so let us add HSDPA (even before

Highspeed data (e.g. HSDPA), mobile TV, IM and wireless broadband. These are the areas that most companies emphasised upon this year. However, beside these over hyped technologies, there are many items in news coverage of 3GSM 2006 that are worth taking note of: - Nokia and Sanyo's collaboration to penetrate the CDMA handset market in USA in direct competition to Qualcomm and Samsung. -

I have been reading an industry report on the Mobile Download business. The report highlighted the following facts:- most downloaders are young people under 25 years old, - surprisingly, most downloaders are from families with low income.- People who watch >5 hours of TV a day are more likely to download mobile content.The report tried to come up with justifications for these intriguing findings,

Every project I see around me suffers from serious lack of coordination and chaos. As a matter of fact it has reached epidemic proportions that can only be eliminated by someone strongly resolute and with serious leadership.Having said that, I'm infamous for being the cynic in my workplace. In my eyes everything seems to be going on wrongly and all decisions appear to me as counter productive and

Having worked for a long time with two major telecomm equipment vendors, I have an insider's view on what goes on behind the flashy brands and rosy corporate image.What appear to be cool and innovative products are in fact extremely suboptimal and inefficient bundles of electronics and poor software which are usually patched and repatched hundreds of times. This is to the extent that it is almost

HSDPA is a 3GPP release 5 feature which promises a maximum of 14.4 Mbps per cell.There is great confusion as to what this throughput really means and to what extent it can be utilised.I've seen vendors and operators alike push for overblown node-b designs that can connect to multiple E1 links in order to carry all the HSDPA traffic and then sit back and watch the green bucks roll in the bank

Uncontrolled static electricity discharge can cause damage to electronic equipment, for that reason measures are taken to design handheld devices in ways that protect them from the evils of static electricity. But what if you can utilise static charges in a constructive way? What if you can store static electricity to top-up batteries of various handheld devices?Imagine yourself in a train and
