IoT connectivity





NB IoT

For applications that don’t move while in use and only require minimal bandwidth, NB IoT is a great option. It does not support full mobility (i.e. handoff between towers), but it does not need to, because assets are relatively stationary. Uses for NB IoT include street lighting, industrial monitors, parking and utility meters, heavy equipment tracking, and alarm panels.
It is important to note that while NB IoT may not be mobile, it is transportable. If an asset leveraging NB IoT technology changes locations, connectivity can be re-established with the nearest tower once stationary. Think of a moving company that provides containers as an option for transporting assets. They want to know whether or not the container has been dropped off at the customer’s location and when it has been picked up for delivery. NB IoT can pinpoint its resting location.
But what about its “in-transit” status once the pod is mobile? There is an LTE technology for that, too.

Cat-M

For uses that require a little more bandwidth, but do not require the advanced features of Cat-1, Cat-4, or Cat-6, there is Cat-M. Cat-M fully supports legacy IoT and M2M applications, offering four times the throughput with 50 percent of the battery life as NB IoT. Cat-M is a great option for mobile tracking use cases, such as fleet management, as it can jump from tower to tower without losing connectivity. It is also a great option for applications including building security and management, wearables, and remote patient monitoring.
Take the previous example: If the moving company needs to know if the containers have been dropped off or picked up as well as the in-transit status of the truck carrying the container in real time, then Cat-M would be a better solution.

hreflang? what is it? where does it come from?

Hreflang tags are a technical solution for sites that have similar content in multiple languages. The owner of a multilingual site wants search engines to send people to the content in their own language. Say a user is Dutch and the page that ranks is English, but there’s also a Dutch version. You would want Google to show the Dutch page in the search results for that Dutch user. This is the kind of problem hreflang was designed to solve. And for the  Webmasters who serve several versions of their content in different languages or for users in different countries should use   hreflang annotations   to help Google show the right version in the search results for each user. In this article, " How to implement hreflang tags... ", the author has lay out the steps from begin to finish on the right ways of implementing hreflang tags for your multilingual and multinational web sites. In another article, " hreflang: the ultimate guide ", the author has outlined the

Creating a file-based SWAP on your Beagleboard

On the Beagleboard you should expect to require a swap file given the limitation of how little RAM is available (between 256 MB and 512 MB). Some system programs like apt-get will only run properly when some swap space is present (due to 256 MB not being enough RAM). Some images (such as those from Linaro.org) do not come with a swap partition or any swap space allocated. Under Linux, swap space can be either a dedicated partition or a swap file. Both can be mounted as swap which the OS can access. Creating a Swapfile The following commands will create a 512MB file, limit access only to root, format it as swap and then make it available to the OS: sudo mkdir -p /var/cache/swap/ sudo dd if=/dev/zero of=/var/cache/swap/swapfile bs=1M count=512 sudo chmod 0600 /var/cache/swap/swapfile sudo mkswap /var/cache/swap/swapfile sudo swapon /var/cache/swap/swapfile To tell the OS to load this swapfile on each start up, edit the /etc/fstab file to include the following addi
