Yacht / Marine Telecom – Pepwave Max BR1 – Embedded 4G LTE or World Mode 3G Modem …

14. February 2013 21:23 / Leave a Comment / Alan Spicer

The Pepwave Max BR1 is giving me some excitement here lately … previously the built-in modem in Pepwave Max was 3G although you could add a 4G LTE data card to it. But this version has built-in 4G LTE. (Available WINTER 2013.)

New iOS Jailbreak release … Cydia is having an Evasion “invasion” …

5. February 2013 07:48 / Leave a Comment / Alan Spicer

 I’ve been waiting on this one for AWHILE … I couldn’t get off of iOS 5.01 without losing WiFi Apps I need for my work. I had a little bit of trouble but after a Restore / Upgrade the Jailbreak worked. And then I end up with the problem that a TON of other people are facing. Cydia – the App Store for Jail broken iOS devices is swamped with traffic and is giving errors to everything you try to do via Cydia.

photo.PNG

So far my Jailbroken iPhone 4S is pretty bare! I got back all of my Apple sanctioned apps and all my phone contacts and even my photos (which worried me since I had to do a restore to get off Jailbroken iOS 5.01) … I’ll have to wait until the traffic to the Cydia related servers slows down to put my tweaks and WiFi Apps and such back on.

See this link for another report on the ~slowdown~ jailbreakers are experiencing:

http://www.computerworld.com/s/article/9236507/iOS_6_untethered_jailbreak_released_Cydia_app_store_flooded

The Windows or Mac application that you have to download to do this Jailbreak thing is called “Evasi0n” … but being Zero Day for this Jailbreak release Everybody and his Brother is trying to download their Tweaks and Apps at the same time. Servers and networks can only handle so much activity and network traffic before they get bogged down. So the Cydia App and the Repositories (sites that store the apps) are having an Evasi0n Invasion … and are failing tonight.

So we’ll have to wait and try again later. One person commented on Twitter to wait until the kiddies have to go to bed around 9:30 pm … but their is a National and International problem with that thinking. East Coast 9:30 pm is only 6:30 pm on the West Coast of the U.S. And what about the rest of the world? There are a lot of time zones to deal with. Who knows how long this will take to settle down.

Update: It finally settled down late at night that night and I got all of my Cydia apps and tweaks back installed. Here is a latest screen shot:

iOS 6.1 Jailbroken Screen shot with Cydia Apps and Tweaks installed

iOS 6.1 Jailbroken Screen shot with Cydia Apps and Tweaks installed

(Barrel App) iOS 6.1 Jailbroken Screen shot with Cydia Apps and Tweaks installed

(Barrel App) iOS 6.1 Jailbroken Screen shot with Cydia Apps and Tweaks installed

A nice twisty – rolling transition instead of the normal boring screens swiping to the left. Also notice the 5 icons across and the multi-icon scrollable dock at the bottom.

Yachts: Put some 4G LTE on your boat … Cradlepoint MBR Router Products

4. February 2013 00:11 / Leave a Comment / Alan Spicer

I still recommend Ericsson W35 for the voice telephone (to PBX) connection … but if you want to try out the faster speed of 4G LTE – consider our Cradlepoint Router Products.

Image – Cradlepoint MBR1400

I just did an MBR95 on a smaller yacht the other day and got 10 Mb/s download speed on Speedtest.net. That’s considerably faster than 3G Internet previously used on that boat. Get your emails (especially with file attachments) faster! And enjoy other video and audio offerrings on the Internet.

An IT company rep. in Mallorca – Balearic Island, Spain is considering MBR1400 for deployment on a yacht. We also have MBR1200B and the MBR95 for different price points and different capabilities. The MBR1400 is  the best one at just $380.00 plus shipping. You can look at all of the Cradlepoint Products on:

http://www.marinetelecom.net/cradlepoint.html (see the Cradlepoint Tab here on the blog.)

The products are easy to install and use … but I can provide assistance (support) if desired for installation and usage. The products can take another Internet Connection (or two on some) and become your Internet Switching Center between multiple Internet Router systems.

P.S. I have a Cradlepoint MBR1400 in hand here – if anyone has a 4G or 3G cellular data card and would like a demonstration onboard a yacht in the Fort Lauderdale area.

Alan Spicer comments … Twitter says it was targeted by hackers, 250,000 accounts compromised

Alan Spicer says:

So what are they going to do TWEET from all of them in a Bot Net style? Sending spam? There has to be a monetary gain behind such a thing … if not just a childish “script kiddy” kind of thing. Prove to your friends that you can hack 200,000 +Twitter accounts and you are IN the Chinese Haxor Club.

Twitter is big enough that this will be squashed rather rapidly. So it will probably just go on some Chinese hacker bravado resume …,

Thanks for the heads up. I am on Twitter … but not as often as some KIDS are. I don’t have to tell my audience when I take a sheite … or when I go to the beach. Which is rare lately unless I am working on a boat at Bahia Mar or Las Olas Docks.

This isn’t a threat to national security … I don’t think. Unless the president twitter account got compromised and they signed the Treaty of Versailles or something all over again.

The internet at large will take an aspirin and be ok in the morning.

Marine WiFi (and every WiFi): ‘N’ wasn’t the eNd – read: 802.11ac new WiFi Standard

1. February 2013 00:02 / Leave a Comment / Alan Spicer

I got a web seminar invite from Information Week on a new WiFi Standard - 802.11ac. But I don’t need to wait for a seminar to read up on the new standard.

http://en.wikipedia.org/wiki/IEEE_802.11ac - Wikipedia has a page on this.

For boats and yachts for now I wouldn’t worry about this on the Marina Hotspot (your topside WiFi antenna for Hotspots – if you have one?) side as of yet. We’re still looking for any benefit from 802.11n which was the last WiFi Standard update. The Internet connection behind a WiFi hotspot might be 10 Mb/s Cable (or less) and so getting a faster link to them wouldn’t make any difference if the backhaul is multiples of slower than the wireless link speed.

However on board the vessel – if you have application(s) that have a “Need for Speed” such as video streaming on board the boat – video camera viewing – other multimedia – engineering applications that need faster speed – or you just want to be in the forefront of wireless technology inside the boat … you might want to start looking into 802.11ac capable wireless access points.

Spatial Streams, Multi-Antenna – Multiple Input Multiple Output (multi-user even?), and 256 QAM – Oh My!

Lions and Tigers and Bears, Oh My!

QAM 16 Demonstration

QAM 16 Demonstration – imagine 256 QAM …

(Digital 16-QAM with example constellation points. [Constellation Diagram])

“Like many digital modulation schemes, the constellation diagram is a useful representation. In QAM, the constellation points are usually arranged in a square grid with equal vertical and horizontal spacing, although other configurations are possible (e.g. Cross-QAM). Since in digital telecommunications the data are usually binary, the number of points in the grid is usually a power of 2 (2, 4, 8, …). Since QAM is usually square, some of these are rare—the most common forms are 16-QAM, 64-QAM and 256-QAM. By moving to a higher-order constellation, it is possible to transmit more bits per symbol. However, if the mean energy of the constellation is to remain the same (by way of making a fair comparison), the points must be closer together and are thus more susceptible to noise and other corruption; this results in a higher bit error rate and so higher-order QAM can deliver more data less reliably than lower-order QAM, for constant mean constellation energy. Using higher-order QAM without increasing the bit error rate requires a higher signal-to-noise ratio (SNR) by increasing signal energy, reducing noise, or both.” [http://en.wikipedia.org/wiki/256QAM.]

“IEEE 802.11ac is a wireless computer networking standard of 802.11, currently under development (Draft 4.0[1]), providing high-throughput wireless local area networks on the 5 GHz band.[1] Standard finalization is in late 2012, with final 802.11 Working Group approval in late 2013.[1] According to a study, devices with the 802.11ac specification are expected to be common by 2015 with an estimated one billion spread around the world.[2]

Theoretically, this specification will enable multi-station WLAN throughput of at least 1 gigabit per second and a maximum single link throughput of at least 500 megabits per second (500 Mbit/s). This is accomplished by extending the air interface concepts embraced by 802.11n: wider RF bandwidth (up to 160 MHz), more MIMO spatial streams (up to 8), multi-user MIMO, and high-density modulation (up to 256 QAM).”

* Alan’s Final Note: So 802.11ac should be coming to a theatre near you – showing up in Laptop and other portable devices and becoming available in wireless access points. Also note this new standard is in the 5 Ghz band as opposed to the more commonly used (up till now?) 2.4 Ghz band. It’s a different antenna if we were talking about a topside antenna … but in portable computing devices and on board access points the antennas will be already built-in. The question of what frequency band came to me again while re-reading the above quote paragraph – as we already have to be careful with 2.4 Ghz channels because they overlap. It’s common in installation use only channels 1, 6, and 11 in the 2.4 Ghz WiFi band because of this overlap in the channels RF bandwidth. It will be interesting to know, going forward, how the 5 Ghz band is used as far as overlap and interference with other services (e.g. radar and military applications … example given TDWR) see:

http://en.wikipedia.org/wiki/List_of_WLAN_channels

If you are interested in the interference / overlap situation in 5 Ghz, as I am, have a look at:

http://www.smallnetbuilder.com/wireless/wireless-features/31694-why-80211ac-will-kill-the-5-ghz-wi-fi-band

“This will enable faster peer-to-peer Wi-Fi Direct data transfer and higher quality screen-casting/throwing from phones and tablets to large flatscreens via Wi-Fi Display. But again, the higher speeds will come at the expense of using wider swaths of bandwidth in the currently relatively uncluttered 5 GHz band. There goes the neighborhood!”

* As some ham radio guys would say with the U-Verse expanded frequency band use (now in the same frequencies used for H.F. SSB Radio) – “There goes the neighborhood!”
