Huawei E5776s-32 MiFi and Cellhire SIM

MiFi devices have been available for some time and Huawei seem to be the market leader. They act as a local WiFi hotspot and allow other devices to connect to them and they connect to the Internet over a GSM/GPRS/3G or 4G network.

Initially MiFi units were quite simplistic, but they now have quite a lot of functionality built-in and can be configured through a web interface.

Huawei's new E5776s-32 supports a 4G connection and 2.4 Ghz at B,G and N. It has a funky monochrome LCD screen and takes a TS9 connector for an external antenna allowing for extra radio sensitivity. The manual with the device claims the following:

• offers up to 6 hours of working time and up to 300 hours of standby
• supports 10 WiFi clients
• provides up to 150 Mbps 4G LTE and 43.2 Mbps 3G download
• supports 2.4 GHz and 5GHz WiFi 802.11b/g/n
• features menu-style LCD UI with support for multiple languages

In testing, the device didn't support WiFi over 5GHz, but maybe this will come later with a firmware update. The unit is configured through a web page access through a browser on a connected device.

The 4G connection is a class Cat 4 giving the unit a maximum throughput of 150Mbps on the mobile radio interface along with 150Mbps/s for the N wireless so should allow for decent bandwidth through the unit. The settings are easy to configure withou too much baffling information and so it should only take 5 mins to get up and running.

It's customary to test units in an urban environment where 4G is well established but there is also a lot of Wi-Fi around, much of which is free. In order to do a more useful test, the MiFi was taken to Wales. The unit was placed into the glove box of the car with the external antenna connection to an aerial on a magnetic mount stuck to the outside of the car. This gave an incar hotspot for the duration of the trip. The Huawei gave a very good signal for most of the journey where as the Note 4 would indicate a poor signal. Doing a straight comparison between the phone and the signal with the Huawei and aerial showed that in every location the E5776s got a better signal.

There were some times where it looked like there was enough signal through the mobile phone network for the E5776s but phone and latop refused to connect to the E5776s for periods of up to 10 minutes, the phone showing that is was waiting for the internet quality to improve, but this may well have been a congested cell in Vodafone's network or other network issue. Generally though it was worth using the superior connection of the MiFi.

In conclusion it makes sense to use the Huawei MiFi in rural areas with an external aerial so it can handle the connection to the mobile network and devices connect over WiFi. If it's your mobile phone connected the battery will last noticeably longer as it won't have to use battery power talking to cells that are a long distance away.

The MiFi came with a Cellhire SIM which allows International roaming for a fixed cost (though not particularly cheap), the SIM is guaranteed to work abroad and cost are capped which is more suited to the business traveller. As the SIMs are 3G and 4G you'll get access to those networks when travelling, quite a lot of consumer services only give access to slower 2G networks.

Urban situation 4/10 Everywhere else 8/10

Ofcom clears the way for 700MHz broadband

Ofcom, the Super Regulator, has published a statement that will clear the 700MHz band (694 MHz - 790 MHz) for use by mobile broadband services (likely to be additional bands for LTE services).

It is expected that the auctioning of this band will raise significant revenue for the treasury as well as having a positive economic benefit by allowing mobile network operators (MNOs) access to increased spectrum allowing them to provide better data services. The 700MHz band has very good propagation properties (i.e. signals pass through walls etc well) which should improve mobile coverage in rural areas.

Digital Terrestrial Television (DTT) services will continue to operate in the 600MHz band, though multiplexes will use MPEG-4 and DVB-T2 technologies (any tuner that can decode Freeview HD will work with these technologies).

The main users affected by this will be Programming and Special Events (PMSE) radio microphones, who will have to move to other bands.

Whitespace technologies may also be affected, however these haven't really taken off in a big way and even Neul that has built equipment to utilise whitespace have recently concentrated on licensed spectrum (and have been purchased by Huawei).

This may seem daunting, but Ofcom is not proposing that these changes come into effect until 2020 (and maybe 2 years earlier in 2018), this is in-line with European harmonised spectrum strategy.

BT and EE launch LTE trial (in Cornwall)

BT Wholesale and Everything Everywhere have launched a trial of LTE (long term evolution or 4G) services running in Cornwall.

The trial will support 200 users split between mobile and fixed users in an area where fixed broadband is currently unavailable.

The trial uses equipment form the Chinese vendor Huawei and will run until next year.

Cornwall is a convenient area to run these kinds of trial as there is poor fixed line coverage, the conversion from analogue to digital TV has already taken place (so the 800MHz spectrum is available) and even if they get a few things wrong, there's no one to interfere with anyway.

As a shared trial, BT and EE will be ensuring the equipment can share access to the two seperate networks.

Alcatel-Lucent develops 400Gb/s processor

This isn't a normal CPU that comes in a general purpose computer, but a network
compute engine and 400Gb/s is high speed. As mobile data and Internet data incre
ase the core backbones have to support more and more traffic.
LAN speeds have been increasing over the years and while a few years back everybody was happy with 10Mb/s Ethernet, now home (wired) LANs are 100Mb/s or even 1000Mb/s (1Gb/s).

At the Internet Service Providers (ISPs) they have to cope with much higher speeds and LANs might run at 10Gb/s or even 40Gb/s and very shortly 100Gb/s (the 100Gb/s standard was only ratified last year and it takes a while for vendors to produce equipment based on the standards). The next speed increase takes the LAN up to 400Gb/s.

It's all very well running high speed LANs but they need to connect to other things (just like a home router with multiple LAN connections) and the equipment needs high speed network processors to be able to move data around and work out where it should be going in real-time.

Traditionally the high speed core router market has been dominated by Cisco followed by Juniper and more recent Huawei from China. This now put Alcatel-Lucent back in the race for providing the next generation of Internet systems.

Alcatel-Lucent's processor is known as the FP3 and can handle 70,000 simultaneous HD video streams or 8.4m cloud sessions and it's these types of services which are expanding rapidly and the core networks need to stay ahead of consumer demand.
