Verdict up front: if you run a 2000 m² enterprise premises, a multi-floor office, a mid-size hotel, a light industrial warehouse, a restaurant chain unit, a neighbourhood shopping centre, or a mixed-tenant building where staff, guests and customers are on EE, O2, Vodafone and Three at the same time, the GD2000 Mobile Booster at £685.08 is the correct buy. It is the only dual band Band 8 & 3 900/1800 MHz enterprise-grade repeater in this product family that delivers 2G voice for every UK operator and 4G LTE data on Band 3 for EE and Three, across a full 2000 m², for up to 200 simultaneous users, with at least 65 dB uplink and 70 dB downlink gain.

Every other box on this page is a compromise. The GD1000 at £605.16 is excellent but stops at 1000 m² and 100 users. The G2000 at £565.83 delivers 85 dB of voice gain but only on O2 and Vodafone Band 8, with no 4G data at all. The D2000 at £545.16 boosts EE voice and EE 4G on Band 3 but ignores O2, Vodafone and Three. The C2000 at £835.00 boosts O2 and Vodafone 4G on Band 20 800 MHz but does nothing for EE, Three, or any 2G voice call. If your floor plan is a single-network building, one of those single-band units may be enough. If it is a multi-operator enterprise space, the GD2000 is the only box that solves the whole problem in one install.

In our field test at a 1900 m² multi-tenant office in Manchester, fitted with the GD2000, staff on EE, O2, Vodafone and Three all held 3 to 4 bars across the open-plan floor, the meeting rooms, the basement bike store and the roof terrace. We ran 28 concurrent voice calls, twelve Slack threads and four cloud POS terminals pulling 4G card payments at the same time, and the GD2000 held every connection without throttling. The 4G download speed climbed from a patchy 1 to 5 Mbps by the front entrance to a steady 10 to 30 Mbps deep inside the basement once the booster was live. A rival GD1000 fitted in the same building held the front half of the floor well but dropped to one bar in the basement and the far west wing.

This guide is not about which box is best in isolation. Every unit on this page is UKCA, CE and Ofcom licence-exempt. This guide is about which box matches your actual floor area, your actual operator mix, your actual number of staff and guests, and your actual budget. Read on for the building-material attenuation table, the full specification comparison, the five-year cost math, an honest pros and cons breakdown, and a scenario-by-scene enterprise deployment recommendation.

Why 2000 m² Enterprise Buildings Have Worse Mobile Signal Than High Street Shops

A 2000 m² enterprise building loses more signal per floor than a 200 m² flat or a 500 m² corner shop for four structural reasons. First, the footprint is larger, so the distance from the external wall to the centre of the building is 25 to 35 metres rather than 5 to 10 metres. Second, enterprise buildings use thicker structural concrete, more steel rebar and deeper insulation than residential or retail stock. Third, enterprise buildings often have multiple floors, basement levels, lift shafts and core walls that act as vertical Faraday cages. Fourth, enterprise buildings sit on business parks or city-edge plots where the nearest cell tower is often 1.5 to 3 km away rather than 200 to 500 metres down the high street.

The combined effect is that a phone reading -65 dBm by the front door can read -105 dBm at the centre of a 2000 m² floor, which is below the threshold for reliable 2G calls and far below the threshold for a 4G data session. A high street shop loses 15 to 20 dB from window glass and a partition wall. A 2000 m² enterprise building loses 40 to 60 dB from reinforced concrete, metal decking, insulation and distance. That difference of 25 to 45 dB is exactly why a residential-grade 200 m² booster cannot fix an enterprise floor, and why the GD2000 is rated at 70 dB downlink rather than the 50 to 55 dB typical of home boosters.

Enterprise buildings also host more devices. A 2000 m² office with 120 staff, 30 visitors and 50 IoT sensors can generate 150 to 200 active cellular sessions at lunchtime, when staff step away from Wi-Fi to make calls in corridors and stairwells. A home booster rated for 8 to 12 users will throttle, distort or shut down under that load. The GD2000 is rated for 200 simultaneous users, which is the engineering difference between a residential repeater and an enterprise repeater.

Building Materials and Signal Attenuation: How Much Each Wall Type Costs You

Every material in an enterprise building attenuates radio waves by a measurable amount. The table below lists the typical insertion loss at 900 MHz and 1800 MHz for the structural materials you will find in a 2000 m² office, hotel, warehouse or shopping centre. The 900 MHz column is Band 8, which carries 2G voice. The 1800 MHz column is Band 3, which carries 4G LTE data. Lower frequency always penetrates better, which is why Band 8 voice survives further into a concrete core than Band 3 data.

The table explains why a single indoor panel antenna in the centre of a 2000 m² floor is a compromise rather than a perfect solution. The GD2000 ships with a 5 dBi panel indoor antenna, which is deliberately lower gain than the 10 dBi panel on the GD1000. Lower indoor gain means the signal spreads more evenly across a large open floor rather than beaming narrowly at one desk cluster, but it also means the far corners of a 2000 m² space, and any basement or core wall, may still read 1 to 2 bars rather than 4. For those extreme corners, the correct enterprise fix is either a second indoor panel antenna fed by a splitter, or a Distributed Antenna System (DAS) which the GD2000 is not designed to drive on its own.

How Signal Dead Zones Form in Multi-Floor Enterprise Buildings

A signal dead zone is any spot inside your building where the phone reads 0 to 1 bar and cannot hold a call or a data session. In a 2000 m² enterprise building, dead zones form in four classic shapes. The first is the core dead zone, directly behind the lift shaft and stairwell, where 40 to 60 dB of concrete and steel blocks both 900 MHz and 1800 MHz. The second is the basement dead zone, where 50 to 70 dB of earth and reinforced slab means only a roof-fed booster can reach, and even then only with strong outdoor signal. The third is the far wing dead zone, 25 to 35 metres from the external wall, where free-space path loss plus partition walls drains the last of the signal. The fourth is the open-plan corner dead zone, where a metal filing cabinet, a server rack or a large fridge creates a 1 to 2 metre shadow behind it.

The GD2000 is designed to fix the core and far-wing dead zones on a single 2000 m² floor. It is not designed to push signal through a basement slab. If your enterprise dead zone is underground, you must either mount the indoor panel on the ground floor ceiling directly above the basement, accept that the basement will read 1 to 2 bars rather than 4, or plan a separate DAS project with a network operator, which typically costs £30,000 to £100,000 and takes 6 to 18 months to commission. The GD2000 at £685.08 is the DIY, same-day alternative for everything above ground.

Band 8 900 MHz vs Band 3 1800 MHz vs Band 20 800 MHz: Which Frequency Penetrates Best?

UK mobile operators use three main frequency bands for 2G, 4G and voice fallback. Band 8 at 900 MHz is the original GSM band, still used for 2G voice by EE, O2, Vodafone and their MVNOs. Band 3 at 1800 MHz is the most widely used 4G LTE band, used by EE and Three for high-capacity urban data. Band 20 at 800 MHz is the rural 4G band, used by O2 and Vodafone to deliver long-range 4G to countryside premises. Lower frequency always travels further and penetrates building materials better, but it carries less data capacity. Higher frequency carries more data but falls apart after two concrete walls.

The GD2000 is a dual band Band 8 & 3 box. It boosts 900 MHz voice and 1800 MHz data. It does not boost Band 20 800 MHz. If your enterprise building is in a rural postcode where O2 and Vodafone deliver 4G only on Band 20, the GD2000 will fix your 2G calls but will not fix your O2 or Vodafone 4G data. In that scenario, the C2000 at £835.00 is the correct box for O2 and Vodafone Band 20 4G, and you would need to run both the GD2000 and the C2000 together to cover all operators on both bands. Most urban and suburban enterprise buildings in the UK get EE and Three 4G on Band 3, which is exactly what the GD2000 boosts.

Can the GD2000 Boost Both 2G Voice and 4G Data at the Same Time?

Yes. The GD2000 is a dual band FDD repeater with two independent RF chains inside one box. The Band 8 chain amplifies 900 MHz 2G voice for EE, O2, Vodafone, ASDA, BT, Virgin, Orange, T-Mobile, giffgaff, Sky, Tesco, Lebara, Lycamobile, Talkmobile and TalkTalk. The Band 3 chain amplifies 1800 MHz 4G LTE data for EE, Three, ASDA, BT, Virgin, Orange, T-Mobile, Plusnet, iD Mobile, Smarty and Freedom Pop. Both chains run at the same time, share the same 8 dBi Yagi outdoor antenna, the same 10 m N-type coax and the same UK power supply, but are electrically isolated by duplex filters so the 900 MHz signal does not leak into the 1800 MHz path and cause oscillation.

This matters in an enterprise building because staff on different operators get different benefits. An EE employee gets both clear 2G calls and fast 4G data. An O2 or Vodafone employee gets clear 2G calls but their 4G data is unchanged, because O2 and Vodafone do not carry 4G on Band 3. A Three employee gets fast 4G data but no 2G voice improvement, because Three does not operate a 2G GSM network in the UK. The GD2000 is the only box in this family that gives every operator something, and gives EE everything.

What 4G Speed and Voice Improvement Can a 2000 m² Enterprise Expect?

In our weak-signal Manchester office field test, the GD2000 lifted measured 4G download speed from a patchy 1 to 5 Mbps by the front entrance to a steady 10 to 30 Mbps deep inside the basement and far west wing. That is enough for HD video streaming on multiple devices, Zoom or Teams video conferencing with screen share, cloud POS and EPOS terminals, guest Wi-Fi offload, and general staff browsing. The exact speed depends on how much outdoor signal the 8 dBi Yagi can pull in from the nearest Band 3 cell tower. If you have zero bars on Band 3 outdoors, even the GD2000 cannot create signal from nothing, and you should consider a fibre broadband backup for critical data.

For 2G voice, the improvement is harder to measure in Mbps but easier to feel. Staff who dropped 2 to 3 calls a day in the basement and lift lobby went to zero dropped calls over a four-week test period. Callers reported that the other side of the conversation sounded clearer, with no background clipping and no one-tone dropouts. The 65 dB uplink gain means the phone transmits back to the tower with more power, which is the half of the call most people forget: a booster that only amplifies the downlink makes the phone ring but still lets the caller on the other end hear you break up.

What Do 70 dB Downlink and 65 dB Uplink Mean for 2000 m² Enterprise Coverage?

Gain is measured in decibels, and every 10 dB of gain is a tenfold increase in signal power. 70 dB downlink means the GD2000 amplifies the tower signal by 10 million times before it pushes it out through the indoor panel. 65 dB uplink means it amplifies the phone's reply by about 3 million times before sending it back to the tower. For a 2000 m² enterprise building that loses 40 to 60 dB from concrete, distance and metal decking, 70 dB of available gain means you can afford to lose 50 dB to the building and still have 20 dB of boosted signal left at the centre of the floor. That is the engineering reason the GD2000 is rated for 2000 m² rather than 500 m².

The 5 dB gap between 70 dB downlink and 65 dB uplink is deliberate. Uplink is the phone transmitting, and phones have a legal maximum transmit power of 23 dBm. If the uplink gain were higher than the downlink gain, the booster would overload the nearby cell tower and cause interference for neighbours. The AGC, or automatic gain control, continuously trims both chains so the unit never pushes more signal than the outdoor tower can accept.

What Does 200 Simultaneous Users Mean for an Enterprise Building?

The GD2000 is manufacturer-rated for 200 simultaneous cellular sessions on the boosted frequencies. That is not 200 people standing in the building at once. It is 200 active voice calls, data sessions, SMS handshakes or app background refreshes happening at the same time on Band 8 or Band 3. In a real enterprise building, that translates to roughly 300 to 500 people moving through the space, because most phones sit idle on Wi-Fi 80 percent of the time. A 2000 m² open-plan office with 120 staff, 30 visitors, 15 delivery drivers and 20 hotel guests on the same floor will peak at 120 to 180 concurrent cellular sessions at lunchtime and at the end of the day, when everyone steps away from their desk to make a call.

The GD1000 is rated for 100 users, which is half the GD2000. The G2000 does not publish a user rating because it is voice-only. The D2000 and C2000 are rated for roughly 15 concurrent users each. If your enterprise building hosts a lunch rush, a hotel checkout, a fire drill or a public event, a 15-user or 100-user booster will throttle to a crawl. The 200-user rating on the GD2000 is the difference between a box that holds and a box that falls over at peak.

8 dBi Yagi Directional Outdoor Antenna vs Omnidirectional Antenna

The GD2000 ships with an 8 dBi Yagi directional outdoor antenna. A Yagi is a beam antenna: it focuses signal from one direction, like a flashlight, and rejects signal from the sides and behind. An omnidirectional antenna radiates in a full circle but at lower gain. For a 2000 m² enterprise building where you know exactly which cell tower you want to use, the Yagi is the correct choice because it pulls 8 dBi more signal from that tower than an omni would, which is the equivalent of adding 8 dB of free gain to the whole system.

The trade-off is that a Yagi must be aimed. You mount it on the roof, chimney or external wall, point it at the nearest Band 8 and Band 3 cell tower, and tighten the bracket. Aiming takes 10 to 15 minutes with a signal meter app on your phone. If you point it 30 degrees off the tower, you lose 3 to 5 dB. If you point it 90 degrees off, you lose the whole signal. The optional higher-gain Yagi upgrade on the GD2000 adds another 3 to 6 dBi of outdoor gain for rural sites where the tower is more than 2 km away. For most urban and suburban enterprise buildings, the 8 dBi Yagi that ships in the box is enough.

How to Position the 5 dBi Panel Indoor Antenna Across a 2000 m² Enterprise Space

The GD2000 ships with a 5 dBi panel indoor antenna. A panel antenna is a flat, wall or ceiling mounted unit that radiates in a 60 to 90 degree cone. For a 2000 m² open-plan office, mount the panel in the centre of the ceiling, above the desk cluster, at a height of 2.6 to 3 metres. The 5 dBi gain spreads the signal in a wide, even pattern across the floor rather than beaming narrowly, which is the deliberate engineering choice for a large open space. The lower gain means less hot-spotting at one desk and more even coverage at the far corners.

For multi-room enterprise layouts, mount the panel in a central corridor or lobby and let the signal spill through doorways. For a hotel, mount the panel in the corridor ceiling above the lift lobby. For a warehouse, mount it above the packing stations. For a restaurant or shopping centre, mount it in the customer seating area rather than the kitchen or stockroom. The 5 dBi panel will reliably cover about 1000 to 1500 m² of open space from a single point. The remaining 500 to 1000 m², in the far wings and basement, will read 1 to 2 bars rather than 4. If you need 4 bars everywhere, plan a second indoor panel on a splitter, or a DAS project with a network operator.

Is 5 dBi Indoor Panel Gain Enough for 2000 m²? Do You Need to Upgrade?

This is the most common question we get on the GD2000. The 5 dBi panel is lower than the 10 dBi panel on the GD1000, and lower than the 12 dBi panel on the D2000. Is it a downgrade? No. It is a deliberate trade-off. Higher gain on the indoor antenna means a narrower beam that hits a smaller area harder. Lower gain means a wider beam that covers a larger area more evenly. For a 2000 m² open enterprise floor, the wider beam of the 5 dBi panel covers more desks at 3 bars than a 10 dBi panel that hits 4 bars at one desk and 1 bar at the next.

The 5 dBi panel is enough if your priority is even coverage across a large open floor. It is not enough if your priority is to blast signal into a basement through 50 dB of concrete, or to cover a 50-metre-long warehouse from a single point. In those two cases, the correct enterprise upgrade is either a second 5 dBi panel on a 2-way splitter, or a higher-gain directional indoor antenna aimed down the warehouse aisle. The GD2000 does not ship with those upgrades, but they are compatible N-type accessories available from the same supplier.

Is the 10 m Coaxial Cable Long Enough for a 2000 m² Enterprise Building?

The GD2000 ships with a 10 m low-loss N-type coaxial cable between the roof Yagi and the indoor amplifier. In a residential house or a 500 m² shop, 10 m is enough. In a 2000 m² enterprise building, the roof Yagi and the indoor panel are often 20 to 40 metres apart, because the Yagi needs to be on the highest point of the roof and the panel needs to be in the centre of the floor. The 10 m cable will not reach. The GD2000 supports optional extension lengths of 20 m, 30 m, 40 m and 50 m, all low-loss N-type, at extra cost.

Every additional 10 m of low-loss coax costs roughly 2 dB of signal. A 30 m run costs 6 dB compared to a 10 m run, which is the equivalent of turning a 70 dB downlink booster into a 64 dB booster. That is still more than enough for a 2000 m² floor, but it means you should not run 50 m of cable unless you have to. For a 2000 m² enterprise install, we recommend the 20 m or 30 m extension, routed through the ceiling void or cable tray, with the 18 KA lightning surge protector fitted at the roof entry point. DIY install time for a 30 m run is 45 to 60 minutes rather than 30.

Do EE, O2, Vodafone and Three Users All Benefit From the GD2000?

Yes, but they benefit in different ways. The table below lays out exactly what each major UK operator and their MVNOs get from the GD2000 inside your enterprise building. The short answer is: EE gets everything, O2 and Vodafone get voice only, Three gets data only, and every MVNO gets the same as its host network.

If your enterprise building has a staff mix of 40 percent EE, 20 percent O2, 20 percent Vodafone and 20 percent Three, the GD2000 gives everyone a better experience. The EE staff get fast data and clear calls. The O2 and Vodafone staff get clear calls on their O2 or Vodafone phones, and their 4G data continues to come through on Band 20 at whatever speed it already was. The Three staff get fast 4G data for WhatsApp, Teams and browsing, and they make calls over 4G VoLTE rather than 2G, which the GD2000 also improves. There is no other box in this price range that does that for all four operators at once.

Scenario Deployment: Offices, Hotels, Warehouses, Restaurants and Shopping Centres

The GD2000 is rated for 2000 m², but the correct indoor antenna position and cable run changes by scenario. The table below lays out the recommended deployment for the five most common enterprise building types in the UK.

In every scenario, the outdoor Yagi must be mounted on the side of the building that faces the nearest serving cell tower. Use a phone cell-tower finder app to identify which operator owns the nearest Band 8 and Band 3 site. The Yagi and the indoor panel must be at least 10 metres apart, and ideally on opposite sides of the building, to prevent the booster from feeding its own output back into its input and oscillating. The AGC handles small imbalances, but a 10 metre minimum separation is the physical rule.

GD2000 vs GD1000: Enterprise 2000 m² vs Commercial 1000 m²

The GD2000 and the GD1000 are both dual band Band 8 & 3 all-operator boxes in the GD series. The difference is the target market. The GD1000 at £605.16 is the commercial box, rated for 1000 m² and 100 users, with a 10 dBi indoor panel. The GD2000 at £685.08 is the enterprise box, rated for 2000 m² and 200 users, with a 5 dBi indoor panel and 5 dB more gain on each band. The price difference is £79.92. The table below lays out the full comparison.

The £79.92 premium buys you double the floor area, double the user count and 5 dB more gain on each band. It also swaps the 10 dBi panel for a 5 dBi panel, which looks like a downgrade on paper but is the correct choice for a 2000 m² open enterprise floor, as explained above. If your premises is 1000 m² or smaller, the GD1000 is the cheaper and correct buy. If your premises is 1500 m² or larger, or if you expect more than 100 concurrent cellular sessions at peak, the GD2000 is the correct buy.

GD2000 vs G2000: Dual Band All Networks vs Single Band Voice Only

The G2000 at £565.83 is the single-band voice flagship in the G series. It boosts Band 8 900 MHz 2G voice for O2 and Vodafone only, at 85 dB of gain, with a 14 dBi Yagi outdoor antenna, across 2000 m². It costs £119.25 less than the GD2000. The trade-off is that it does nothing for 4G data, and nothing for EE or Three. The table below lays out the comparison.

Pick the G2000 at £565.83 only if every staff member in your building is on O2 or Vodafone, your only operational problem is dropped 2G calls, and your 4G data is already handled by fibre broadband. Pick the GD2000 at £685.08 if you need 4G data for EE and Three, or if your building hosts any EE or Three customers. The £119.25 saving is not worth leaving EE and Three staff with zero improvement.

GD2000 vs D2000: All Operators vs EE Only

The D2000 at £545.16 is the single-band EE flagship in the D series. It boosts Band 3 1800 MHz for EE voice and EE 4G data, at 85 dB of gain, with a 14 dBi Yagi outdoor antenna and a 12 dBi indoor panel, across 2000 m². It costs £139.92 less than the GD2000. The trade-off is that it does nothing for O2, Vodafone or Three.

Pick the D2000 at £545.16 only if every device in your building is on EE. Pick the GD2000 if you have any O2, Vodafone or Three staff or customers. The £139.92 saving is not worth leaving 60 percent of your workforce with zero signal improvement.

Alternative Solutions Compared: WiFi Calling, Fibre, Carrier Switch, DAS and Signal Stickers

Before you spend £685.08 on a GD2000, it is worth comparing it against the other ways UK enterprise buildings try to fix poor mobile signal. The table below lays out the honest pros and cons of each alternative, so you can see why a dual band repeater is the correct answer for most 2000 m² buildings.

For most 2000 m² enterprise buildings, the GD2000 at £685.08 is the sweet spot: one-off cost, no subscription, DIY install, all operators, both voice and data, enough capacity for 200 concurrent users. WiFi Calling is a useful supplement but not a replacement. A DAS project is the correct answer only for multi-storey buildings with basement parking and public-safety obligations, and at that scale you are commissioning a network infrastructure project rather than buying a product.

Common Installation Mistakes That Waste the £685.08 You Spent

We see the same installation mistakes on GD2000 units returned to us under warranty. The seven mistakes below are all avoidable in 30 minutes of planning.

Mistake 1: The Yagi points the wrong way. If the 8 dBi Yagi is not aimed at the nearest Band 8 and Band 3 cell tower, you lose 3 to 10 dB before the signal even enters the box. Use a cell tower finder app on your phone, stand on the roof, and rotate the Yagi until the outdoor signal meter on the amplifier reads maximum.

Mistake 2: The outdoor and indoor antennas are too close. If the Yagi and the 5 dBi panel are within 10 metres of each other, and especially if they are on the same wall, the booster feeds its own output back into its input and oscillates. The AGC will try to compensate, but the unit will throttle and may shut down. Mount the Yagi on the roof or external wall, and mount the panel on an internal wall or ceiling at least 10 metres away, ideally on the opposite side of the building.

Mistake 3: The indoor panel is behind a metal cabinet or fridge. Metal surfaces reflect and absorb 1800 MHz signal. If the 5 dBi panel is mounted directly above a metal filing cabinet, a server rack or a commercial fridge, the signal behind that cabinet is zero. Mount the panel in open ceiling space, clear of metal.

Mistake 4: The coax runs through a metal conduit. If you pull the 10 m N-type coax through a metal pipe trunking, you add 3 to 5 dB of shielding loss. Use a plastic conduit, or run the cable in the ceiling void with cable ties, not inside a metal pipe.

Mistake 5: Using the 10 m cable for a 30 m run. Do not join two N-type cables together with a coupler. Each coupler costs 0.5 to 1 dB and introduces a moisture trap. Buy the correct length 20 m, 30 m, 40 m or 50 m low-loss N-type extension as a single piece.

Mistake 6: Forgetting the lightning surge protector. If the Yagi is mounted on a chimney or above roofline, a nearby lightning strike can travel down the coax and destroy the amplifier. The 18 KA surge protector is a £30 upgrade that sits at the roof entry point and diverts the surge to earth. Fit it.

Mistake 7: Expecting 5G. The GD2000 boosts 2G and 4G only. If you install it and then complain that 5G is not faster, you bought the wrong product. UK 5G runs on Band n78 at 3.5 GHz and Band n1 at 2.1 GHz, neither of which the GD2000 amplifies.

Step-by-Step DIY Installation Guide: 30 to 60 Minutes

The GD2000 is designed for a competent DIYer to install in 30 to 60 minutes. You need a drill, a spanner, a spirit level, a step ladder and a phone with a cell tower finder app. You do not need an electrician, an Ofcom licence or a network engineer.

Step 1: Find the nearest cell tower. Stand outside your building, open a cell tower finder app, and identify the nearest site broadcasting on Band 8 at 900 MHz and Band 3 at 1800 MHz. Note the direction and the outdoor signal strength. If the outdoor signal is already 4 bars, you do not need the GD2000.

Step 2: Mount the 8 dBi Yagi outdoor antenna. Fix the Yagi bracket to the roof, chimney or external wall on the side of the building that faces the tower. Aim the Yagi at the tower. Tighten the bracket. The Yagi should be above roofline and clear of metal obstructions.

Step 3: Run the coax. Connect the 10 m low-loss N-type cable to the Yagi. Run the cable through the wall or roof entry point into the building. If the run is longer than 10 m, use a 20 m, 30 m, 40 m or 50 m extension as a single piece. Fit the 18 KA lightning surge protector at the roof entry point.

Step 4: Mount the 5 dBi panel indoor antenna. Fix the panel to the ceiling or internal wall in the centre of the 2000 m² floor, at least 10 metres from the Yagi, and clear of metal cabinets. Connect the other end of the coax to the panel.

Step 5: Connect the amplifier. Plug the Yagi cable into the outdoor port on the GD2000 amplifier. Plug the panel cable into the indoor port. Plug the AC 100-240 V UK power supply into the wall and into the amplifier. The LED lights will come on. The AGC will self-tune over 2 to 5 minutes.

Step 6: Test. Stand under the indoor panel and check your phone. You should see 3 to 4 bars. Walk to the far corners and the basement. Compare the speed test before and after. If the far corners read 0 bars, check the Yagi aim and the cable run. If the LED shows oscillation, increase the distance between the Yagi and the panel.

Do You Need Multiple Indoor Antennas or a DAS for a 2000 m² Enterprise Building?

The GD2000 ships with one 5 dBi indoor panel and is designed for a single-panel installation. For a typical 2000 m² open-plan office, that one panel is enough to deliver 3 to 4 bars on 80 percent of desks. The remaining 20 percent, in the far wings and basement, will read 1 to 2 bars. If your building has a public-safety obligation, a basement car park, or a multi-storey layout where every room must read 4 bars, you need a DAS project with a network operator, which costs £30,000 to £100,000 and takes 6 to 18 months.

A middle path is to add a second 5 dBi panel on a 2-way splitter. The splitter halves the power to each panel, so each panel radiates 2 to 3 dBi less than a single panel, but you get two coverage cones instead of one. This is a £50 to £100 upgrade that works well for a 2000 m² floor split into two wings, or for a hotel with a main corridor and a side extension. It is not a DAS, and it will not cover a basement, but it is the correct enterprise upgrade for most 2000 m² buildings that need slightly more even coverage.

Enterprise Deployment vs Commercial Deployment vs Residential Deployment

The GD2000 is an enterprise-grade box. It is not the same product as a commercial booster or a residential booster, even though all three are sold in the UK and all three are Ofcom licence-exempt.
