The Gemini PDA, it's as close to a Psion as you'll get (and it's real)

Before the iPhone or even Blackberry, there was a PDA made by a company called Psion, well several, eventually culminating in the Series 5. It was a clamshell design with a keyboard on one side and the monochrome screen on the other. It could run applications and it did basic things like had a calendar, calculator and word processor, all driven by a toolbar running along the bottom of the screen. It also had a 'view' screen to see what was happening throughout your life (well days/weeks anyway).

Unfortunately Psion is no more, however a company called Planet Computers is trying to change that and though the actual Psion can't be resurrected, the Gemini is born. The company was set-up by Dr Janko Mrsic-Flogel who used to resell Psion hardware and develop software and has developed a lot of mobile cloud solutions under another company (Private Planet Ltd).

The Gemini looks and feels like a Psion 5

The PDA on the left is an actual working Psion 5 and the PDA on the right the Gemini - they do look remarkably similar. It's worth noting that the Gemini is also running a view screen that emulates the Psion calendar view, giving access to what's coming up in an easy to read manner.

The next picture shows another comparison, but with a lot of test keyboards too.

The various keyboards are for testing different membrane thicknesses and how 'clicky' the keys are. The current thinking is a softer keyboard which will probably appeal more to modern computer users who are used to the light touch, while programmers would probably prefer the keyboard with a deeper travel and more 'Cherry mechanical' keyboard feel (the programmers will probably lose out). But either way, it's perfect possible to touch type on either one.

Underneath the keyboard sits a big battery (removable Li-Ion 4220mAh) giving 12 hours talk-time and a full 2 weeks in standby.

The screen is a 5.99 inch FHD (18:9) with a resolution of 2160x1080 at 403 ppi and full colour. It looks very good. The Gemini doesn't come lightly spec'ed either with: -

• CPU - Mediatek MT6797X Helio X27 with 10 cores (2 x Cortex A72 @ 2.6GHz, 4 x Cortex A53 @ 2.0GHz, 4 x Cortex A53 @ 1.6GHz
• GPU - Quad core Mali T880 MP4 @ 875MHz
• RAM - 4GB
• ROM - 64GB
• Sound - Stereo speakers (either side of display)
• Microphone - integrated behind display and external 3.5mm jack
• Bluetooth - v4.0
• GPS - GPS and AGPS
• USB - 2 USB C ports (OTG support)
• Camera - front facing 5MP
• Sensors - accelerometer, gyroscope, compass, magneto-sensor, light sensor
• SD Card slot - takes at least 128GB, may take 256GB

The Gemini comes in 2 versions, WiFi only and WiFi with 4G. The specs for the 4G model are: -

• WiFi - 802.11a/b/g/n/ac
• GSM - 850/900/1800/1900 Mhz
• CDMA - 850/1900 Mhz BC0 BC1+ EVDO
• WCDMA - 900/2100 Mhz
• LTE - 1/2/3/4/5/7/12/17/20/41 and VoLTE

The 4G models has SIM slot (under the top lid) and both have an external camera module space (for a later rear 5MP camera module). There are also 5 fully programmable RGB LEDs on the lid, which can be programmed for fun, but also to light up to indicate, say, who's calling. When the phone rings, it can be operated without ever opening the case.

The Gemini's default operating system is Android (currently 7.1) and it will run many standard Android apps, but in order to make it more Psion like, there's a toolbar at the bottom of the screen that can launch specified apps (as well as using various Psion like key combinations).

There's a dedicated voice assist button giving access to Google's voice system.

A quirk is the Gemini can also dual-boot and the second partition holds Linux (currently Debian, but Planet will open source at least enough of the Linux side so other variants can be installed). Linux can also be run as a VM under Android (yes it does work).

All Planet apps can be run locally (with no need for access into the cloud), or they can link into the Private Planet cloud service (or Google's).

There will be a range of peripherals, but on launch there's a USB-C to HDMI adapter and a USB-C hub with 3 USB-A sockets, Ethernet port (and maybe others). There's also a USB-C mains charger and a nice leather pouch.

Using the HDMI adapter, an external HD display is easily driven running video/etc.

The Gemini is currently selling 'in-demand ' on Indiegogo (the original target was for $200,000 and it's now at over $800,000).

The WiFi only version sells for $299 and the WiFi + 4G is $399 (prices are likely to go up by $200 after the campaign).

The Gemini is a very nice unit and completely usable as a mobile phone, but with a full features of a PDA with a touch-typable keyboard so allowing productivity apps and leisure apps like video to run, even at the same time and it will fit into a jacket pocket.

Ofcom to undertake a Strategic Review of Digital Communications

Ofcom, the Super Regulator, is holding a Strategic Review of Digital Communications to promote competition and investment in converged digital communications services.

This is mainly concerned with infrastructure services such as broadband, but will also cover mobile 4G and future 5G services and "over-the-top" services (i.e. services deliver on top of Internet services such as VoIP, messaging systems such as WhatsApp which is replacing SMS, etc).

Ofcom last held a review 10 years ago after BT's infrastructure operation was separated into a distinct entity (BT Openreach, though still part of BT Group).

There have been many changes since the last review such as the merger of T-Mobile and Orange into EE (which has subsequently been purchased by BT) and consolidation in the ISP market (02, Tiscali, AOL, Be, Easynet).

Since 2005

• broadband adoption has increased from 31% to 78%
• take-up of bundled services has risen from 29% in 2005 to 63% today
• significant commercial and public sector investment in superfast broadband has resulted in 78% availability five years after deployment started. Adoption of this new service is now 27%
• mobile broadband availability has increased significantly, with 3G increasing from 82% to 99% of premises, and 4G services available to 73% of premises. Mobile broadband take-up is now 67%
• new entrants have shown strong growth in some areas (for example, local loop unbundling now accounts for 44% of broadband connections, up from 17% in 2005)

While Ofcom can not predict the overall output it will likely encompass

• Efficient investment: How can incentives for efficient private sector investment and innovation be maintained and strengthened, to ensure widespread availability and high quality of service?
• Competition: What should be the focus of competition policy in future networks (the 'enduring economic bottlenecks')?
• Deregulation: What is the scope for deregulating networks and services downstream of any 'enduring bottlenecks'?

Ofcom is planning to complete the review by Summer of 2015.

Ofcom consulting on releasing public sector spectrum

Ofcom, the Super regulator that has responsibility for spectrum allocation, is consulting on the planned release of MoD spectrum in the 2.3GHz and 3.4GHz bands.

The bands being made available are 2350 to 2390 MHz (40MHz) and 3410 to 3600 MHz (150MHz). It is expected that these bands will be licensed for use by mobile network operators for 4G/LTE services, though other broadband services could also be offered.

Unfortunately these bands are also used by amateur radio and it is likely that severe interference can be expected. Therefore Ofcom has proposed three recommendations to minimise interference.

• i) Remove access to the adjacent bands
• ii) Retain access to the adjacent bands on the current terms but with clarification of the notice period required for future amateur use to cease if amateurs cause interference to other users in the release band or the adjacent band
• iii) Restrict amateur access to a smaller part of one or more adjacent bands.

Of these 3 Ofcom's preferred option is ii) whereby Ofcom will require amateurs to stop using these bands if there is interference to licensed users (with a notification period).

Ofcom wants to make changes to amateur licenses such that if the proposals are accepted would

• i) remove the frequencies of the release bands from the licence.
We have set out three options for the adjacent bands and are recommending option two which if implemented would:
• ii) introduce a procedure to enable removal of additional frequencies (i.e. the adjacent bands) to quickly if harmful interference arises in the future.

Though this will adversely potentially affect amateur radio users, the benefit to the overall population will be increased with access to more spectrum for LTE or other services.

The consultation has now closed.

Ofcom consults on Spectrum Management Approach in the 70/80GHz bands

Ofcom, the Super regulator that looks after spectrum management is holding a consultation on proposals to change the management and authorisation approach used to manage the bands 71 - 76 GHz and 81 - 86 GHz (70 / 80GHz). These offer 2 x 4.75 GHz of bandwidth allowing very high capacity links (over 1Gb/s) which are not supported in lower frequency bands. These bands have been available for use since 2007.

Currently the spectrum is not managed at is up to the users of these bands to co-ordinate amongst themselves on use (self coordinated spectrum), though currently use of the spectrum is minimal compared to lower frequency bands. However with the rapid adoption of 4G services and the bandwidth that will be required to remote cell-sites, usage can be expected to rapidly increase and operators are now worried that self-coordinated management will not suffice as links in these bands will have to provide 99.99% to 99.999% availability, so any interference could be disastrous for mobile networks.

Ofcom is proposing to manage the spectrum in a mixed manner offering partial self-coordinated use and partial managed use.

Ofcom coordinated approach: 2 x 2 GHz

Guard band: 2 x 250 MHz

Self coordinated approach: 2 x 2.5 GHz

NOTE Image (C) Ofcom.

This will allow non-critical links to be operated as now in the higher part of the bands while more critical services will be in the lower part of the bands managed by Ofcom (using the same regulatory environment as for fixed links in lower bands).

This should be good news for users and backhaul links get very expensive very quickly and can limit the growth of a mobile network (in terms of coverage), so being able to use protected spectrum to maintain high bandwidth links to cell-sites and allowing the networks to provision more 4G cells.

The full consultation is available on-line and stakeholders may respond here, the by 5th October 2013.

Ofcom opens 2G and 3G bands for 4G use

Ofcom, the Super Regulator that oversees radio spectrum (amongst its many duties) has published a statement allowing mobile network operators (MNOs) to utilise their 2G and 3G bands for 4G use, without applying for a license variation.

This affects the 900MHz, 1800MHz and 2100MHz bands. Ofcom has also allowed an increase in power of 3dB in the 900MHz band to align it with power levels in the 800MHz band.

This is in-line with Ofcom's policy to liberalise licenses and make them technology neutral and will allow the MNOs to roll-out 4G (LTE) services on any of their spectrum without regulatory hinderance.

EE and 3 may share 800MHz spectrum

Both EE and 3UK won 2 x 5MHz chunks of 800MHz spectrum in the recent UK spectrum auction for deploying LTE/4G mobile services. O2/Telefonica and Vodafone both won 2 x 10MHz chunks (with O2 having a coverage obligation).

EE currently has deployed LTE in their 1800MHz spectrum and they will relinquish some of this (2 x 15MHz) to 3UK by the end of 2013 when 3UK can deploy their own LTE services.

Generally the minimum requirement to deploy LTE is a requirement of at least 2 x 10MHz, so the two lots of 2 x 5MHz may cause EE and 3UK issues, so they are considering joining their efforts and sharing their joint spectrum, giving them access to a joint amount of 2 x 10MHz.

Currently this is just in the planning stage and it may not be technically feasible, though there is no reason why it shouldn't be.

Ofcom proposes to allow 4G on all 2G and 3G bands

Ofcom, the Super regulator, has opened a consultation to allow the liberalisation of all existing 2G and 3G bands so they can also be used for 4G (LTE) services.

This would mean O2 and Vodafone can refarm both their 900MHz 2G spectrum and their 2.1GHz 3G spectrum, EE (the combined entity of Orange and T-Mobile) have already started refarming of their 1800MHz spectrum, but they will be allowed to also refarm their 2.1GHz 3G spectrum. 3UK only have (currently) 2.1GHz 3G spectrum but will be able to refarm this and when EE transfer around 25% of their 1800MHz spectrum to 3UK they will also be allowed to use this for 4G (though this is not expected to happen until September 2013).

This is separate from any spectrum that is currently being auctioned (800MHz and 2.6GHz) though Ofcom has not yet announced who is bidding for what spectrum.

3UK have announced that when they launch 4G services, they will not differentiate on price between 4G and 3G services. The consultation is available here and interested stakeholders can respond on-line.

Everything Everywhere sells spectrum to Three (but they cant use it)

Everything Everywhere (EE) the combined company made up to Orange and T-Mobile has sold off some of their 1800MHz spectrum to Three UK (3). The terms of the deal have not been specified.

EE has 2 x 60 MHz bands in 1800MHz and they were forced to relinquish some of this spectrum by the European Competition Commission (2 x 15 MHz chunks) and they have no done this by selling it to 3.

However there's a twist as 3 won't actually get hold of the spectrum until 2013 (which is pretty much the maximum time frame the Competition Commission allowed), which gives EE a whole year to offer 4G (LTE) services in the 1800MHz band and be a UK monopoly for 4G services (Ofcom granted EE a license variation to allow 4G services in EE's 1800MHz band earlier this week).

All of the other mobile network operators have cried foul play as they have to wait for spectrum to become available in 800MHz and 2.6GHz as part of the digital dividend, but Ofcom won't auction the spectrum until 2013 and it's not expected to be available until at least the end of 2013.

By offering LTE services it's likely devices such as the iPhone 5 and other smartphones and tablets will be able to use these frequencies as they're already used in Australia and some Asia Pacific countries. Though UK Broadband is also offering LTE on their spectrum, it's in a band that's not commonly used for LTE and they are having specific devices made to use it.

Ofcom announces 4G auction

Ofcom the super regulator has published a statement on the forthcoming 4G auction of 800MHz and 2.6GHz spectrum.

The 800MHz spectrum has become available due to the switching off of analogue television services (the digital divide) while 2.6GHz was reserved for future IMT-2000 (3G) services.

The 800MHz spectrum will be auctioned as 2 x 30 MHz blocks (paired spectrum) while the 2.6GHz band will consist of 2 x 70MHz blocks and a 50 MHz single (unpaired) block. This spectrum amounts to an 80% increase on all spectrum allocated to date.

Existing spectrum holders can bid for increased allocations, though spectrum will be reserved for a new entrant (i.e. one that isn't Telefonica O2, Everything Everywhere and Vodafone), this new entrant could be Hutchison 3G (who currently do not have any 2G i.e. sub 2 GHz spectrum.

The 800MHz licensee will have to meet 98% indoor coverage which implies 99.5% outdoor coverage, by 2017. The licensee will also have obligations to cover 95% of the populations of England, Scotland, Wales and Northern Ireland.

Ofcom will not reserve any spectrum for low power localised services, though a low power provider can apply for a national license.

Ofcom is reserving spectrum portfolios for a new entrant, these are

Portfolio	800 MHz	1800 MHz	2.6 GHz
1	2 x 15 MHz
2	2 x 10 MHz		2 x 10 MHz
3	2 x 5 MHz	2 x 15 MHz
4		2 x 15 MHz	2 x 20 MHz

EverythingEverywhere have to relinquish 2 x 15 MHz paired spectrum as part of their arrangements with the EU when they combined T-Mobile and Orange. Ofcom have considered the request from EverythingEverywhere as to allow them to ref arm their 1800 MHz spectrum for LTE us independently from this spectrum auction and will announce its results later this year.

Ofcom has published a draft legal document which implements the auction rules, the consultation will close on 11th September 2012.

Ofcom will invite application to bid before the end of 2012 with the auction starting in 2013 and licenses awarded in March 2013.

Winners of spectrum are expected to roll-out LTE services on the new spectrum starting in the middle of 2013 with consumer services being available after that.

Everything Everywhere 4G LTE trial in Cumbria

Everything Everywhere (the combined Orange and T-Mobile mobile network operators) has been running a trial in Cumbria using LTE in it's existing 1800MHz spectrum. The trialists were made up of users from local businesses and they either used dongles or mobile routers. Speeds of up to 20Mb/s (download) were achieved, though this depended on the number of users per mast and distance from the mast. The area isn't well serviced by fixed line broadband which meant high speed mobile via mobile was a boon to users. EE have applied to Ofcom for a license variation to allow them to utilise LTE on their existing 1800MHz spectrum nationally and Ofcom have opened a consultation on whether to allow this. The other MNOs are objecting, though EE have to return some of that spectrum as part of their merger conditions.

Ofcom opens test facility for testing SRDs

Ofcom the super regulator covering media, broadcasting, radio, telecommunications and postal services is opening a testing facility in Baldock on March 5th 2012.

Short Range Devices (SRDs) such as consumer wireless headphones, wireless microphones (those used for public address in non commercial environments), certain wireless alarms and devices for tracking supermarket stock can be used without a license across Europe. They operate in the band between 863 and 870 MHz (known as the SRD band).

This band is in the wider current analogue TV band which is due to be switched off in April 2012 and will be auctioned in 2013. Though the auction will be technology neutral, it is expected to be used for Long Term Evolution (LTE) otherwise known as 4G services.

The testing facility will allow SRDs to be tested in the presence of LTE emissions from handsets/dongles to see the effects and ensure they continue working.

Ofcom publishes possible 4G capacity gains

Ofcom the super regulator today published its report into what capacity gains that 4G networks could provide compared to existing capacity on 3G networks.

In summary compared to existing HSUPA 3G networks, there will be an increase of 3.3x which will increase to 5.5x by 2020 i.e. 3.3 to 5.5 times as much traffic can be put over the equivalent spectrum which will be opportune as data usage increases.

However network operators will need to manage the topology of their 4G networks more carefully than current 3G networks.

The statement may be found here.

2.6GHz spectrum Auction on again?

ZDnet has reported that the Government has sent proposals for 800MHz, 2.6GHz and 2G/3G bands to Ofcom, which could mean Ofcom holding an auction for the 800MHz and 2.6GHz bands later this year.

There has been controversy with various particulars of these spectrum auction with initially T-Mobile taking Ofcom to court saying the 2.6GHz band (which was reserved as an IMT-2000 i.e. 3G band in case the new 3G entrant failed) could not be allocated until 2G refarming had been sorted out. Currently the 2G bands are exclusively reserved for 2G use, naturally the Mobile Network Operators (MNOs) want to re-use 2G bands for 3G services. However refarming was fraught with further complications as Vodafone and O2 have 900MHz spectrum while T-Mobile and Orange have 1800MHz (1.8GHz) and 900MHz propagates better than 1.8GHz.

Things were further muddied when T-Mobile and Orange announced their merger (which has since been approved) as the combined company would have more than the maximum allowable spectrum.

Things have also simplified as the maximum spectrum a MNO can have has been increased from 2 x 60MHz to 2 x 90MHz, 2G spectrum will be allowed to be used for 3/4G services and licenses will become indefinite and tradable (the 2G licenses are currently set at 15 years). Also the 800MHz license will be awarded to 2 licensees, but they will have to give guarantees of 99% population coverage which should stimulate rural broadband.

Though 800MHz is optimal spectrum (it has extremely good propagation characteristics (and penetrates building well), BT are still thought to have an extreme interest in the 2.6GHz spectrum as this will allow them to offer WiMAX (or other wireless broadband) in rural areas and 3G services in urban locations.

Though the landscape is looking more positive, there may still be legal action from the MNOs as has occurred in other countries.
