So how do you explain the larger number of reported rapes in Sweden then?

http://www.thelocal.se/19102/20090427/

"Sweden has the highest incidence of reported rapes in Europe - twice as many as "runner up" the UK, a new study shows."

I wonder how the fact that India and China went to war in 1962 impacts these decisions. They also still share a disputed border.

Would not surprise me if this influences how the Indian government feels about their telecoms using equipment from ZTE or Huawei.

Sorry, forgot about AMR which a voice codec (Adjustable Mode Rate or something). Aha, "Adaptive Multi-Rate audio codec" according to our friend wikipedia.

I thought this was a geek heavy site and that networking would be somewhat understood.

In "lay man"'s terms, cellular standards before LTE (I am talking mostly of 3GPP standards but I assume this applies to WiMAX as well) are really really messy.

A normal UMTS radio access network which has evolved from GSM to UMTS might be amix of TDM, ATM och IP based networks with legacy protocols such as SS7. Through that together with general telecom wierdness where much intelligence is deep inside the network.

These networks are optimizing for running voice traffic, so when you are running VoIP you are pushing what the networks are capably of. Also, since there are usually 3-4 nodes between your phone and the gateway to the packet core you will have latency issues since the network is not putting your VoIP-session in a high QoS class.

I am not really sure if you are interested in knowing the gory details, but that was a quick overview. There should be RF- and core-network engineers here on /. who can explain these things more in detail, I only have experience from R&D of these systems in a lab environment.

VoIP = Voice over IP

UDP = User Datagram Procotol

GTP-U = GPRS (GSM Packet Radio System) Tunneling Protocol Userplane. A tunneling protocol which is setup by the radio access network towards the packet core network for transporting your IP traffic from your UE (user equipment, e.g. phone, modem or other device).

GGSN = The gateway (Gateway GPRS Support Node) node where all IP traffic from the radio access network enters the packet core.

UMTS = Universial Mobile Telephony System, which is mostly implemted as WCDMA everywhere except China where TD-SCDMA is used. These names for the L1 protocol, also known as the air interface.

DS0 = Digital Signal 0, a 64kbit/s transmission standard.

T1 = 1.544Mbps physical connection which can carry up to 24 DS0

STM-1 = 155Mbit/s framing standard for optical networks based on SDH (Synchronous Digital Hierarchy).

Multiplexing = Taking several bit streams and combining them into one stream to send it over one physical interface.

Inverse Multiplexing = Taking a high bit rate connection and splitting it into many "virtual" lower bit rate connections. For example making a whole bunch of DS0 (64 kbit/s remember?) connections from the STM-1 (155Mbit/s remember?) connection.

Voice is circuit switched in UMTS so of course there are different "channels", or tubes if you like. Voice is mostly likely AMR coded over the air interface which is then sent over a ds0 over a T1, either physical or inverse multiplexed over a STM-1 further into the circuit switched core network.

So, yes it will be much for efficent than your run of the mill VoIP which will travel over as UDP over a GTP-U tunnel terminated in the GGSN.

Now it came! :)

It will be using AT&T's WCDMA/HSPA network. Good stuff!

So I need a phone, which already does most of what this thing does, before I can use it on the subway?

If you need another device to make it mobile it is not really a mobile device is it? Anyhow, how do I tether it? Do I need to buy this AND a iPhone?

How can you claim to be making a mobile device if it does not have mobile broadband? This thing yearning for a mobile internet connection so bad. The only reason that I can think of is that Steve is waiting to deploy this on Verizon's coming LTE network.

In what way is that "GSM"'s fault?

Please explain what socialism has to due to the enormous growth in broadband in Sweden after the de-regulation of the telecom industry?

Also, this is a private company providing the service.

Cisco is behind the telecom giant Ericsson here, they already have a blade system delivered to Telstra:

Cisco, behind old and boring telecom? :)
