Answer up front: if your office floor, co-working space, rural warehouse, hotel, pub, restaurant, retail unit, clinic or multi-floor community hall mixes EE-family SIMs (EE, BT Mobile, Asda Mobile, Virgin Mobile) with O2, Vodafone and Three members and needs boosted EE voice calls alongside a universal 3G fallback rather than a data-only chassis, the DW2000 at £935.00 is the pick: it pairs Band 3 at 1800 MHz for EE-family voice, text and 1800 MHz 4G LTE with Band 1 at 2100 MHz for 3G UMTS data, voice and SMS across EE, O2, Vodafone and Three, cleans at ≥70 dB uplink and ≥75 dB downlink commercial gain, outputs ≥27 dBm behind a ≤5 dB noise figure, and covers up to 2000m² (21,528 ft²) for up to 200 users across four indoor whip zones expanded to up to 10 antennas through a multi-way splitter tree with the high-gain Yagi directional aerial included, the 3 dBi whip indoor antenna, a 10m outdoor coax plus a 5m indoor cable and the AC 100–240V to DC 5V UK Type plug.

The pairings differ before price: the DW2000 pairs Band 3 with Band 1 — EE voice and 1800 4G on Band 3, universal 3G on Band 1; the DW1000 carries the identical Band 3+1 band plan for a 1000m² commercial premises with 100 users at ≥70/≥75 dB gain, ≥20 dBm output, Yagi included and four indoor antennas on a 4-way splitter; the CD2000 tunes Band 20 at 800 MHz rural 4G data with Band 3 at 1800 MHz, with no call band and no Band 1 3G; the CW2000 tunes Band 20 at 800 MHz with Band 1 universal 3G, but it never tunes Band 3, so it cannot boost EE-family voice calls. The DW2000 at the same £935 tier versus the CD2000 and CW2000 is a pure band-plan choice; the DW2000 versus DW1000 is a premises-size, user-count, output and antenna-count gradient step of +£250.

The £0.00 DW2000-versus-CD2000 and DW2000-versus-CW2000 gaps buy different second bands rather than more machine: same 2000m², same 200 users, same ≥70/≥75 dB gain, same ≥27 dBm output class, same Yagi class, same 10m outdoor plus 5m indoor cable. The DW2000 keeps Band 3 at 1800 MHz for the EE family's voice calls and 1800 4G, and Band 1 at 2100 MHz for universal 3G; the CD2000 keeps Band 20 at 800 MHz rural data and Band 3 data but no voice band and no Band 1 3G; the CW2000 keeps Band 20 rural 4G and Band 1 universal 3G but no Band 3 voice. The DW1000's −£250 gap buys the same two bands at half the room size, half the users, lower output class and four antennas rather than ten; the DW500's −£450 gap buys the half-tier 500m² commercial class at ≥60/≥65 dB with three antennas.

This page compares the four chassis side by side rather than in a roundup: the DW2000, the DW1000, the CD2000 and the CW2000, with the CG2000 Band 20+8 legacy 2G model noted where it sits in the band matrix. It separates the two roles each chassis fills — a data or voice carrier band versus a universal fallback band — sizes the shared gain, output, cable and spec class, maps each MVNO to its host network, and gives a five-branch decision tree that follows which SIMs your staff and guests hold, whether VoLTE covers the premises, whether the weak row is voice, rural data or 3G, whether the premises really reach 2000m², and whether EE-family voice appears at all.

All four UK units are UKCA and CE certified, Ofcom licence-exempt, ship free within the UK on 1 to 2 day handling plus 10 to 15 day transit, and carry a 365-day mail return window with lifetime technical support. None carries 5G NR; the DW2000, DW1000, DW500, DW250, DW200 and DW100 carry Band 1 3G, while the CD2000 carries neither a voice band nor 3G. All run from the AC 100–240V 50/60Hz to DC 5V UK Type plug. The rest of this page numbers every band, the £0.00 and £250 gaps before you order, and the five-year cost before the decision tree.

Before the tables, three rules keep the comparison honest. First, the chassis split into three distinct UK bands: Band 3 at 1800 MHz (uplink 1710–1785 MHz, downlink 1805–1880 MHz) carries the EE host network's voice calls, text and 1800 MHz 4G data, reaching direct EE and the BT Mobile, Asda Mobile, Virgin Mobile, Orange, T-Mobile and The People's Operator MVNOs that ride the EE host network; Band 1 at 2100 MHz (uplink 1930–1990 MHz, downlink 2110–2180 MHz) carries 3G UMTS data, voice and SMS for EE, O2, Vodafone and Three; Band 20 at 800 MHz (uplink 832–862, downlink 791–821) carries the rural 4G data channel across the major networks; Band 8 at 900 MHz carries O2/Vodafone legacy 2G voice, which the DW chassis do not tune. Each chassis pairs exactly two of these channels, so the comparison decides which pair your office floor, warehouse, hotel or clinic actually needs.

Second, the pairings differ: the DW2000 pairs Band 3 with Band 1 — EE voice and 1800 4G plus universal 3G; the DW1000 pairs Band 3 with Band 1 at the 1000m² commercial tier; the CD2000 pairs Band 20 with Band 3 — rural 4G data plus EE 1800 data, no call band and no 3G; the CW2000 pairs Band 20 with Band 1 — rural 4G data plus universal 3G, no Band 3 voice. The DW2000, CD2000 and CW2000 share the 2000m², 200-user, ≥70/≥75 dB and ≥27 dBm class; the DW1000 sits at the 1000m², 100-user, ≥70/≥75 dB and ≥20 dBm commercial tier; the DW500 sits at the deliberate 500m², 50-user, ≥60/≥65 dB half-tier. The DW2000 question is purely "which two bands do my SIMs need indoors?", and the DW1000 question is purely "does my premises fit the half-size tier?"

Because the trio's price, 2000m² space, 200-user cap, ≥70/≥75 dB gain and ≥27 dBm output are identical, this comparison never turns on power or size between the three £935 chassis; it turns on band plan and host network. A business that only ever holds one network's SIMs can use the narrowest data unit; a mixed-workforce office, hotel or campus on EE-family voice requirements and O2/Vodafone/Three staff or guests needs the Band 3 plus Band 1 pairing of the DW2000.

Coverage figures assume reasonable donor signal outside and sensible antenna separation: the rated 2000m² covers an office floor, commercial premises, co-working space, warehouse, hotel, pub, restaurant, retail unit, clinic, multi-floor building, community hall or large trading floor split into separate structures; the DW1000's 1000m² covers a large shop, mid-size business or half-floor premises. On a strong −70 to −90 dBm donor the DW2000 can add up to 10 indoor antennas through a 2/3/4-way cascaded splitter tree and extra cable, as the note "Expandable coverage by adding indoor antenna, splitter, cable if the outside signal is strong" describes; the DW1000's included Yagi and four-antenna layout cover the 1000m² premises. The tables below compare specs, the £0.00 tie, the £250 step and one five-year cost before the decision tree.

Read the voice and fallback rows before the price: the DW2000 and DW1000 keep both a Band 3 EE voice path and a Band 1 universal 3G fallback; the CD2000 keeps neither; the CW2000 keeps Band 1 3G but no Band 3 voice. The coverage, user, output and antenna rows then decide whether the DW2000's enterprise tier or the DW1000's commercial tier matches the measured premises.

The £0.00 trio ties buy different band pairs rather than more machine; the only gradient step in this page is the DW2000-to-DW1000 move of +£250 for the doubled coverage, doubled user cap, enterprise output headroom and ten-antenna tree. Gain stays ≥70/≥75 dB on the DW2000, DW1000, CD2000 and CW2000; the DW500's ≥60/≥65 dB half-tier gain belongs to the 500m² business class rather than this enterprise comparison.

The DW2000 and DW1000 carry the identical Band 3+1 band plan: Band 3 at 1800 MHz for EE-family voice, text and 1800 4G, Band 1 at 2100 MHz for 3G UMTS data, voice and SMS across EE, O2, Vodafone and Three. Both clean at ≥70 dB uplink and ≥75 dB downlink gain, both ship the high-gain Yagi directional outdoor aerial, both include the 3 dBi whip indoor antenna, the 10m outdoor low-loss coax and the 5m indoor cable, both run from the AC 100–240V to DC 5V UK Type plug, and both offer the 20/30/40/50m outdoor cable and 18KA surge protector as paid variants. The differences are the enterprise gradient: coverage, user cap, output class and antenna layout.

The +£250 buys the doubled 2000m² space, the doubled 200-user cap, the ≥27 dBm enterprise output class that drives a ten-antenna splitter tree through insertion loss, and the multi-way splitter layout for a second floor, distant warehouse wing, hotel annex or hospital corridor. The DW1000's ≥20 dBm output and four-antenna layout serve a 1000m² commercial premises with one hundred active devices; stretching it to a 2000m² HQ, multi-floor building or campus leaves the distant zone quiet, the user cap overwhelmed and the splitter legs starved after the first cascade.

Take the DW1000 when the measured floor plan is one commercial premises up to 1000m², staff and guests total under one hundred, and four whip zones cover reception, open-plan floor, meeting rooms and a rear office. Take the DW2000 when the premises span two floors, a warehouse plus offices, a hotel with public areas and guest wings, a hospital wing with corridors and waiting rooms, a school or campus with multiple rooms, or a conference centre approaching two hundred active devices; the ≥27 dBm output and ten-antenna tree are what keep the last splitter leg clean rather than overloading the commercial tier.

The CD2000 at £935.00 matches the DW2000 on price, 2000m² coverage, 200-user cap, ≥70/≥75 dB gain class, ≥27 dBm output class, Yagi class and cable bundle, but tunes Band 20 at 800 MHz rural 4G data with Band 3 at 1800 MHz for the EE 1800 data layer. It carries no dedicated voice channel and no Band 1 3G fallback: a call that would ride a boosted voice or 3G path stays native indoors, and an O2, Vodafone or Three member has rural 4G data but no boosted fallback if 4G drops.

The CD2000 suits a data-first warehouse, office or rural premises where the 800 MHz coverage is the weak link and native calling already holds on the handsets. It cannot give an EE business a boosted Band 3 voice path in the DW2000 sense, and it cannot give O2, Vodafone or Three members a Band 1 3G fallback. If your staff or guests report dropped calls, weak call tone or failed handover when 4G weakens, the CD2000 does not fix that row; the DW2000 does, because it keeps Band 3 voice and Band 1 3G in the same chassis.

The CW2000 at £935.00 also matches on price, space, users, gain and output class, but tunes Band 20 at 800 MHz rural 4G data with Band 1 at 2100 MHz for universal 3G. On O2, Vodafone and Three it pairs rural 4G with a Band 1 3G fallback; on EE it provides Band 1 3G fallback but never tunes Band 3, so the EE voice call path is not boosted. The CW2000 is the closest technical sibling to the DW2000: the two share Band 1 and the same 2000m² gain and output class, and the £0.00 tie decides whether the second band should be Band 3 EE voice and 1800 4G (DW2000) or Band 20 rural 800 4G (CW2000).

The CW2000 is the right box for an O2/Vodafone-led warehouse or rural business that wants rural 800 MHz 4G plus a universal 3G fallback and has no EE-family voice requirement. An EE, BT Mobile, Asda Mobile or Virgin Mobile business that needs boosted Band 3 calls should choose the DW2000 rather than the CW2000; on the CW2000 those SIMs keep Band 1 3G fallback but their call path runs native indoors.

The CG2000 at £935.00 pairs Band 20 at 800 MHz with Band 8 at 900 MHz for O2 and Vodafone 4G data plus legacy 2G voice, again at the 2000m² and 200-user class. It does not tune Band 3 at 1800 MHz, so there is no EE 4G data channel, and it does not tune Band 1 at 2100 MHz, so there is no universal 3G fallback on EE, O2, Vodafone or Three. The CG2000 suits an older O2/Vodafone-led warehouse or site that still relies on the 900 MHz 2G voice layer and needs 800 MHz rural data; it is the narrowest pair in the quartet for a modern EE-business HQ or mixed-network enterprise premises, where both 4G data and 3G fallback matter. In the decision tree below, the CG2000 appears only as a legacy 2G note rather than a primary branch.

An MVNO rides the host network's masts and radio channels, so the booster band that matters to a giffgaff SIM is the band its O2 host uses, not the giffgaff brand name. Map every SIM your staff, guests, tenants or patients hold before choosing between the DW2000, CD2000 and CW2000.

On this map, an EE-hosted BT, ASDA or Virgin SIM needs Band 3 for boosted calling; the DW2000 carries Band 3, the CD2000 carries Band 3 data without a voice path, and the CW2000 carries no Band 3 at all. An O2-hosted giffgaff, Sky, Tesco or Lycamobile SIM and a Vodafone-hosted Lebara or Talkmobile SIM need Band 1 3G fallback or Band 20 rural data; the DW2000 and CW2000 carry Band 1, the CD2000 carries Band 20 data only. A Three-hosted iD or Smarty SIM follows the same split: Band 1 fallback on the DW2000 and CW2000, Band 20 data on the CD2000, no boosted fallback on the CD2000.

Work the branches in order; stop at the branch that matches your premises rather than buying the biggest sticker.

1. Large office building, enterprise HQ or corporate floor. A Birmingham or Manchester HQ on EE Business with mixed BT Mobile, giffgaff, Sky and Three staff SIMs needs Band 3 voice for the EE family and Band 1 fallback for every other host; at 1000 to 2000m² across open-plan floors, reception and meeting rooms, the DW2000's ≥27 dBm output and up to ten whips cover the layout; a single-floor 1000m² office under one hundred devices takes the DW1000.

2. EE-Business large enterprise or mixed-network workforce. Where company contracts split EE, O2, Vodafone and Three SIMs across departments, the voice band matters on the EE handset and the fallback band matters on the other three; the DW2000 or DW1000 covers both rows in one Ofcom-exempt box, while stacking a CD2000 for data and a separate voice band later costs more than the single Band 3+1 chassis.

3. Large warehouse, distribution centre, factory or logistics site. Steel cladding, rack rows and yard steelwork weaken both voice and data. A delivery-centre SIM mix of EE-family voice, O2 and Vodafone maintenance phones and Three fleet devices needs Band 3 plus Band 1; the rooftop Yagi aims at the nearest mast, and the splitter tree places whips by bay, office and dispatch office. A data-first warehouse with native calling holds on the CD2000; an O2/Vodafone rural site needing rural data plus fallback holds on the CW2000.

4. Hotel, hospital, school, campus or shopping arcade. Guests, patients, students and visitors arrive on every host and every MVNO. Reception, corridors, restaurant, waiting rooms, classrooms, shop units and back offices need boosted Band 3 calling for EE-family visitors and Band 1 fallback for the rest; a 2000m² multi-room premises approaching two hundred devices takes the DW2000, a 1000m² clinic, school wing or large shop takes the DW1000. A data-only retail unit with native calling compares the CD2000.

5. Whole multi-floor building, rural estate or conference centre. A three-floor conversion, rural manor house with conference rooms, or a mixed-use estate with offices, function rooms and residential zones spreads whips across floors and wings. The DW2000's ten-antenna tree and ≥27 dBm output balance the splitter legs over distance; plan cable length and splitter insertion loss before fixing the Yagi, and use the paid long-cable variant where the aerial cannot sit within 10m of the booster.

Day one, the DW2000, CD2000 and CW2000 tie at £935.00; the DW1000 sits at £685.00; the DW500 sits at £485.00; the CG2000 sits in the same £935 legacy class. The five-year row decides what the band gap costs in a second purchase.

The CD2000 buyer later adds a voice band and a Band 1 3G unit on top of the same £935 already spent; the CG2000 buyer later adds Band 3 4G and Band 1 3G; the CW2000 buyer later adds Band 3 for EE calls; the DW1000 buyer who outgrows a 1000m² premises moves up to the DW2000 rather than stacking smaller units around an HQ floor, warehouse or hotel wing. The single DW2000 at £935 wins the EE-family HQ floor, mixed-network enterprise campus, 200-user hotel, warehouse, hospital, school or conference centre on both day-one and five-year cost; the CD2000 wins only when rural 800 4G data matters and calls already hold natively, the CG2000 wins only for a legacy O2/Vodafone 2G site, and the CW2000 wins only when O2/Vodafone rural 4G plus 3G matters and EE voice never needs boosting.

Basic setup takes 10 to 15 minutes: mount the Yagi with a clear mast view, keep the whips a sensible distance inside, run the 10m outdoor coax from the BS outdoor port to the MS indoor port with the 5m indoor cable completing the run, power from the UK plug, and read steady green before testing. Keep a minimum 10m vertical separation between outdoor and indoor antennas where the floor plan allows, and do not power on until both antennas are connected. On a strong −70 to −90 dBm donor, a multi-way splitter tree and extra coax feed up to 10 indoor antennas for reception, open-plan floor, warehouse bay, hotel corridor, clinic wing, campus floor or conference hall; the included Yagi is aimed at the nearest mast in a weak −97 to −105 dBm rural location.

The splitter loss budget matters at ten antennas: each cascade stage divides signal and adds insertion loss, so plan the tree as a first-stage splitter near the booster feeding second-stage splitters on each floor or wing, keep cable legs as balanced in length as practical, and place whips where reception is weakest rather than evenly by room size. Use the paid 20/30/40/50m outdoor cable only where the Yagi cannot sit within 10m of the indoor booster, and fit the 18KA surge protector on an exposed rooftop Yagi, long roof run or warehouse steelwork mount. The verbatim expansion note reads "Expandable coverage by adding indoor antenna, splitter, cable if the outside signal is strong."

All units carry UKCA, CE and RoHS marks, are Ofcom licence-exempt under the mobile repeater technical standard, ship free within the UK on 1 to 2 day handling plus 10 to 15 day transit, and carry a 365-day mail return window with lifetime technical support. The booster needs 1 to 2 bars of external donor signal to amplify and cannot create signal in a fully dead spot; none of the chassis carries 5G NR, and Band 20 rural 4G appears only on the CD2000, CG2000 and CW2000 rows.

For an EE-business HQ, mixed-network enterprise campus, large warehouse, hotel, hospital, school, shopping arcade, whole multi-floor building, rural estate or conference centre where BT, ASDA and Virgin SIMs need boosted Band 3 voice calls and every host needs a Band 1 3G fallback across 2000m² at the ≥27 dBm enterprise output with up to ten indoor zones and the Yagi already in the box, the DW2000 at £935.00 is the pick: Band 3 voice and 1800 4G together with Band 1 universal 3G in one Ofcom-legal UKCA box, no second voice purchase planned.

For a single-floor 1000m² commercial premises under one hundred active devices with four whip zones, the DW1000 at £685 carries the same Band 3+1 plan at the commercial tier. For a data-first warehouse or office prioritising rural Band 20 800 MHz 4G over calls, the CD2000 at £935 covers that data job at the same gain, size and kit, provided voice and 3G fallback are not required. For an O2/Vodafone-led rural business wanting rural 800 MHz 4G plus universal 3G rather than EE voice, the CW2000 at £935 covers that narrower path at the same gain, size and kit, provided the Band 3 EE call band never appears. The CG2000 at £935 remains a legacy O2/Vodafone 2G option only.

Quick verdict: the £935 trio shares gain, size, users, output class, Yagi and cable, so the DW2000 versus CD2000 versus CW2000 choice is a band-plan decision rather than a power decision — DW2000 keeps Band 3 EE voice and Band 1 universal 3G, CD2000 keeps rural data without calls or fallback, CW2000 keeps rural data plus 3G without the EE voice band; the only gradient step is DW2000 versus DW1000, where +£250 doubles coverage, doubles users, raises output to ≥27 dBm and expands four zones to a ten-antenna tree, and a mixed-network enterprise needing boosted EE calls alongside universal 3G across a 2000m² premises should stop comparing data-only chassis and take the DW2000.
