2. A crossover, crossover SUV, or crossover utility vehicle (CUV) is a type of sport utility vehicle-like vehicle built with unibody frame construction. Crossovers are often based on a platform shared with a passenger car, as opposed to a platform shared with a pickup truck.Because of that, crossovers may also be referred as 'car-based SUVs'. Compared to truck-based SUVs, they typically have.

The United States had the 'Crosley' automobile, and Great Britain had the non-related marque, 'Crossley'. To differentiate Crosley's overseas export automobile product, the re-badged name 'Crosmobiles' was used.

Crossmobile Tech

I've been a Xamarin Developer for about a year or so. As a good modern developer, I google a lot during my working hours. Not once or twice but several times I've bumped with this post on the first page of my search results. I can obviously see why this post is relevant but as it's been a long time since it was written, I thought maybe I could share a counterpoint. Not that there's anything wrong with the author, au contraire. If I was to evaluate Xamarin on early 2013 I would possibly reach a conclusion very close to his. But time has passed and I feel comfortable enough as a mobile developer to say the exact opposite: I do recommend Xamarin for cross-mobile development, and I'm going to explain why on the next few lines.

Code-sharing: the Holy Grail of mobile development

For me, the second biggest advantage of the Xamarin world is the possibility to share code between the three platforms (number one is write C# instead of Obj-C and Java!). Before Xamarin.Forms, I would say that realistically you could share 40–50% of code on an regular app using Xamarin. Which was good enough for me, by the way. The possibility to use the same core between different platforms was by itself very tempting. Imagine you could write your unit tests only once, fix non-UI bugs on the three platforms simultaneously, reuse code from your website, webservice or desktop app etc. In summary, less code to maintain. Cool huh? Now, if you choose to develop your app using Xamarin.Forms (which, I have to say, it's not suitable to every situation), code-sharing can easily break the 90% mark. And I'm saying this by my own experience. 'Xamarin.Forms is a cross-platform natively backed UI toolkit abstraction that allows developers to easily create user interfaces that can be shared across Android, iOS, and Windows Phone[1]'. It's still under development but you can already write a pretty decent app with it. Outside the UI domain, if your company uses .NET as it's main platform, you can easily include your previously developed libraries and reuse even more code. Maybe someone already wrote some class to handle that annoying calendar logic on your website, you shouldn't have to write it again, right?

Ecosystem and Community

Nowadays, the Xamarin community is pretty big. Of course it doesn't even compare to the Java/iOS/HTML communities (and it never will) but in my practical experience it doesn't make that much of a difference. 'Why?', you'll ask me. Because most of the pain you're gonna have during the development of a mobile app relates to the platform you're dealing with, not the language you're writing your code. So, when I need to google for 'how to change UINavigationBar title color' or 'how to create a custom navigation drawer for Android', I don't even include the word 'Xamarin' on my query. You can easily translate any Java or Obj-C solution into C# code. In fact, you can even use native components and libraries like the ones found onCocoaControls on your Xamarin app. You'll have a little more trouble when hitting Xamarin.Forms barriers but normally I hangout on the same dark places where iOS and Android geeks live: StackOverflow.

Learning curve

Obviously, when you choose Xamarin, you're adding a third complexity layer into your development scenario. But again, this is not a big deal. If you're not a C# developer, you'll be amazed when you start using things like LINQ, async/await operators and so many other C# black magic. If you already are an experienced .NET developer, you'll feel empowered, able to develop mobile applications, no matter the platform. There are a few ifs and buts — like linker behaviors, JIT and a few other things — , of course, but overall it will be pretty easy to have a good exciting start. Again, if you choose to use Xamarin.Forms , you'll have more things to learn, but it pays off (remember, +90% of code-sharing, right?).

Xamarin bugs

Here I end up having the same thoughts as the author of the post I mentioned on the first paragraph. The only reason why my experience with Xamarin was not 100% smooth were the bugs, specially on Xamarin Studio, their OSX IDE. Don't get me wrong, it's an incredible tool, I love it, it's getting closer and closer to Visual Studio, but the constant updates not rarely added some annoying bugs that made me rollback my version. It doesn't happen as often as it did a few months ago but when it does, it's very frustrating. Xamarin is growing very fast as a company and this sorts of things tend to happen very rarely as time goes by.

Some extra toys

The good thing about dealing with a commercially backed technology is tooling. And Xamarin is getting the hang of it. At last year's Evolve — Xamarin's anual convention — they presented a few awesome tools, that I'll briefly mention: Xamarin Insights, a real-time app monitoring tool, Android Player, a incredibly fast Android simulator and the most impressive of all: Xamarin Test Cloud, a solution to run automated acceptance tests on more than 1.000 real devices, simultaneously. This one I recommend to every mobile developer, since you can run any iOS and Android applications on it. It's not cheap but it's really amazing.

Summary

Before my conclusion, I'd like to mention that I'm not anyhow related to Xamarin and I'm not receiving any benefits for this post. This is simply my view as someone who's spending most of the day with this particular technology. And in my view, Xamarin is by far the best solution for cross-mobile development, specially if you consider the competition: things like PhoneGap, Ionic and Appcelerator. Let's face it: html for mobile development is still a badly-resolved promise. There are a lot of medium and big sized companies placing their bets on Xamarin, building from extremely polished corporate apps to big successful games. Give it a try. If cross-mobile is a key thing to you or your company, there is a huge chance you'll end up using Xamarin in the near future.

The CROSSMobile Van

Why?

Connecting theory to practice for wireless networks requires a substantial investment in lab facilities. But even so, the more interesting studies involve real topographies, real antennas, and real user equipment with real users. Bridging the gap often involves extensive planning, logistics and setup to create a real network in the field.

What?

Cross Mobile Platform Development

The CROSSMobile project at CMU’s Silicon Valley campus includes an on-campus cellular network testbed, supporting experimentation at all levels of networks. In addition to this fixed network, we’ve designed and built a mobile RF laboratory that allows us to take this capability into the field — with the ability to create, run, instrument and study cellular, WiFi, and narrowband networks. This mobile lab also includes local compute servers, a satellite ground station and a stand-alone power plant that give us the opportunity to create a full mobile network wherever we go.

We created the concept for our mobile lab by studying emergency communications vehicles that other organization had assembled. We observed that many, if not most, were designed to house many traditional fixed-band radios. Using the software-defined mobile network approach that we applied to our on-campus network, we built the mobile lab using software-defined radios and software-defined networking. All of the core computing, including the software-defined radios themselves, run within a unified virtualization environment in the van. This same environment supports both virtualized network functions as well as service machines — a local computing cloud — that is integrated with the wireless network. This integration and flexibility make it straightforward to configure the van for different applications. Drone-based data collection and real-time visualization use the same infrastructure as our Survivable Social Network (an emergency communications service).

How?

Our van began its life as an honest-to-goodness ambulance for the City of Los Angeles. We selected an ambulance as our vehicle of choice because it provides multiple power sources (alternator, shore power, battery), some natural places for equipment (more on that below), storage space for equipment, and decent creature comforts.

Re-fitting the ambulance involved putting in a shock-mounted equipment rack where one of the paramedics used to sit (see the photo on the right), putting in a 42-foot pneumatic antenna mast where the oxygen bottle used to go, creating a full roof walk with ladder, making it easy to attach various fixtures to the top of the mast, and filling the rack with networking and computing equipment.

Capabilities

The van is currently outfitted to provide four access networks supported by three backhaul networks, undergirded by four power sources.

Access Network

• Our software-defined LTE network that is band-agile
• A mast-mounted WiFi access point for 2.4 / 5 GHz WiFi coverage
• A Motorola XPR8300 repeater, providing DMR (digital mobile radio) coverage. This repeater is also connected to the internet through our soft switch. With a live internet connection, our DMR handheld radios can access the worldwide DMR network
• A low-power, wide-area network (LP-WAN) using LoRa radios

Cross Mobile Platform

Backhaul Network

• The van can re-link to the internet four different ways: via a multi-operator cellular router, by WiFi (if available), by wired ethernet, or via an Inmarsat ground station. Flexible, software-defined routing allows our van to inter-network with other in-the-field networks as well.

Power Sources

• A high-capacity alternator
• Three marine batteries
• A shore power inlet and charger
• A backup gasoline generator

Computing

• Onboard rackmounted servers, virtualized with Xen

Field trials

The van is in regular use for field experiments at Camp Roberts, CA (including Field Experiments sponsored by the Naval Postgraduate School — NPS-FX), providing communications, computation, and flight operations support for our drone fleet. The van has also made guest appearances at emergency preparedness events and is in regular use on and around campus.
